Autumn delayed vegetable cultivation techniques

The selection of cultivated bean varieties for cultivation of late-delayed dwarf beans should be adapted to varieties with strong adaptability, wide adaptability to temperature, early maturing and high yield, such as French bean (also known as tender bean, Beijing fast bean, etc.), black bean, and dwarf. As early as 18, Chang'e 2, New Zealand 3 and so on. Suitable varieties of kidney beans cultivated on the ground include Qiu Kang 19, Huang County 8 inch, Zhucheng Laolai, Bifeng, Yangbai 313, Chunfeng No. 2, Fufeng, Ha Caidou No. 1 and so on. Appropriate sowing in the middle and lower reaches of the Yellow River, the appropriate sowing time for the cultivation of late-cultivated dwarf beans with a small arch shed is in late August, and the suitable sowing time for the cultivation of autumn dwarf beans in Yangshuo is in early September. Sowing early as soon as possible, the product is on the market early, can not reach the purpose of delayed listing; late sowing temperature can not meet the requirements of dwarf bean growth and development, not only the slow growth of plants and pods, and easy to fall out of flower, Lower production. Dwarf bean cultivars are generally sowed directly with dry seeds, with a row spacing of 33 cm and a hole spacing of 30 cm. Four to five seeds per hole are sown and the soil is sowed after sowing. Field management should be cultivated in time after emergence. When the soil is arid, pour 1 small water, combine topdressing with watering, and apply 10-15 kg of ammonium sulfate per acre, and then cultivate the soil to increase soil permeability and promote seedling rooting. After cultivating the seedlings for 10 to 15 days, apply 10-15 kg of ammonium sulfate and water. After watering, cultivating once, and then controlling watering to avoid plant growth. Plants grow until the flowering and weeding stage to stop watering to prevent falling flowers. When the largest pod grows to 2 to 3 centimeters in length, pour water once more, and combine with water to flush with diluted manure. After the plants grow up, due to their hiding effect, the water in the loquats is lost more slowly. The water can be poured every 7 to 10 days depending on soil moisture. Plastic film covering the beginning of October, Yangshuo cultivation must be used to fight the wall, stand wind barrier, using a small arch shed cultured arches. Because nighttime low temperature is not conducive to the growth of bean, film insulation should be covered. After the temperature has gradually decreased in the middle and late October, when the temperature is less than 20°C during the daytime, the film should be kept warm, and proper ventilation at noon to prevent the occurrence of high temperature and affect plant flowering and fruit setting. At night, if the temperature cannot be maintained above 10°C after covering the film, cover the grasshopper. After entering the month of November, the film shall be tightly capped, with little or no ventilation, and grasshoppers shall be covered as soon as possible, and thickened if necessary. If the insulation of the insulation material is good and the temperature is properly managed, the harvest period can be extended from late November to early December. Green pepper greenhouses, green pepper greenhouses in the summer and late postponed cultivation should use medium-late maturing varieties and strengthen management, so as to achieve better economic benefits. In the summer after the high temperature, in order to promote the main branch results, improve the commercial nature of the fruit, the top of the branches should be cut after two sections. After pruning, the top dressing and watering work are strengthened to promote the development of new shoots. After the fall, when the minimum temperature in the outside world is lower than 15°C, it is necessary to cover the plastic film and carry out the postponed cultivation. The time for the sheds should not be too early or too late. The prematurely high temperatures are not conducive to the growth of the fruits; too late, the temperatures are low and the fruits are difficult to mature. The work of the shed can be carried out step by step. At the beginning, only the roof of the shed is buckled and it is like a ceiling. As the temperature drops, the thin film around the shed must be tightly closed at night and be opened again during the day. When the outside temperature drops below 15°C, the entire shed shall be tightly closed during the night, and no longer ventilated when the temperature in the shed is no more than 15°C during the daytime, and plastic mulches shall be placed on the plastic film around the greenhouse and on the south of the greenhouse to prevent thermal insulation. Promote fruit ripening. After the fruit is buckled, the fruit enters the inflating stage, and 500 kilos of human urine or 10 to 15 kg of urea is applied per mu, and carbon dioxide gas fertilizer may be added to promote the fruit's rapid expansion. Since then, the management of greenhouses and greenhouses has been mainly based on thermal insulation and ventilation. In order to avoid excessive humidity in the shed, irrigation can be controlled. As long as the soil is not too dry, in principle no longer watering. If the humidity in the shed is too high, the ash or dried soil can be applied in the pod. Zucchini selection of fine varieties of cultivated autumn delay Zucchini should choose early maturation, disease resistance, moisture resistance, shade tolerance, low temperature, high yield and strong varieties, such as the early generation, a litter of monkeys, Algeria and so on. When the delayed sowing squash is planted during the appropriate sowing and cultivation period, due to the gradual decrease of the temperature, the illumination is poor, and the plants are susceptible to premature senescence, and the grafting cultivation is suitable. There are a variety of grafting methods, generally rely on the connection method. Squash should be sowed before grafting and black seed pumpkins should be sown after 2 to 3 days. Seeds of zucchini are sown at a spacing and spacing of 5 to 8 cm. After sowing, 3 cm of fine soil is covered. After 3 days, black seed pumpkin seeds are sown by the same method. After sowing, in order to prevent seedlings from drying out and rain showers from affecting emergence, a small arch shed can be added and covered with a film, and the temperature can be controlled at 25° C. to 28° C. After 70% emergence, the film is removed. Grafting and management of the first cotyledon of Zucchini is the appropriate time for grafting. The specific operation procedure of the docking method is: excavate rootstock seedlings and eliminate their growth points, cut a knife at a depth of 45 to 1 centimeter below the cotyledon of the rootstock with a blade at a 45 angle, and the depth is 2/5 to 1/2 of the embryonic axis. About 1 cm long, and then take the scion (squash), and cut 1.5 centimeters below the cotyledon with a blade at a 45-degree angle, 1/2 to 2/3 of the depth of the embryonic axis, equal in length to the rootstock. After the anvils and scion's interface are matched, the graft clips can be clipped. After grafting, the grafted seedlings are planted on well-prepared seedbeds and watered while planting. After the planting, an arch shed was set up, covered with a film and covered with a grass cover. After 3 to 4 days, the grasshopper was gradually removed. After 10 days, the radicles under the interface of the zucchini were cut off, and the ventilation volume was increased after the wound had healed. When the seedling grows to 3 leaves 1 heart to 4 leaves 1 heart, it is suitable for colonization. After the management and colonization, the temperature is maintained at 25°C-30°C to facilitate seedlings sowing, and when the temperature exceeds 30°C, the air is released in time, and the temperature is controlled at 20°C-25°C after the seedlings are sown to prevent the seedlings from growing. When the outside temperature is gradually reduced to 12 °C ~ 15 °C, cover grasshoppers at night, but cover early cover to extend the lighting time. Before the opening of the first female flower, the daytime temperature was controlled at 22°C-25°C; after root cucumber was sitting, the daytime temperature was controlled at 22°C-28°C to promote fruit growth and development. Every day from 8 to 10 am, the open female flowers are coated with 15 to 30 ppm of 2,4-D solution on a flower stalk and style to facilitate sitting. After harvesting the first loquat fruit, the cranberries are lifted and the side vines are wiped off. If the side vines grow tender guava, 2 to 3 leaves can be kept and the top buds can be removed. When harvesting the first loquat fruit, the weight of the fruit will be harvested in time of about 0.3 kg so as to prevent falling pods, causing premature aging of pods and other female flowers. To select good varieties of tomatoes, to cultivate tomatoes in late autumn in greenhouses, use varieties with high resistance to virus disease, low light resistance, high temperature resistance, and strong growth potential, such as Maofen 802, Shuangkang 2nd, Qiangfeng, Sukang 5, Jiafen Number 10 and so on. Strengthen the temperature, light management of tomato colonization in greenhouses, the external environmental conditions to meet the normal growth and development of seedlings, this time without the need to shed, with the gradual decline in temperature, from the end of September to early October shed. After the shed, the front edge of the greenhouse should be lifted during the day to cool the air and cover it at night. The temperature of the shed should be controlled at 23°C to 28°C during the day and 15°C to 20°C at night. After the tomato enters the late growth stage, the insulation work should be strengthened. At night, the grass can be covered around the greenhouse to make the minimum temperature within the shed not lower than 8°C. Under the condition of ensuring the normal growth of the tomato, the pods should be covered as soon as possible. To extend the lighting time. In case of cloudy snow weather, it is also necessary to lift the grasshoppers during the day after the snow is stopped to increase the lighting in the shed. Rational fertilization Irrigation before replanting basal fertigation, application of high quality manure per acre 5000 ~ 7500 kg, 100 kg of diammonium phosphate, after the fertilization will be deep enough to make rake. After planting, the seedlings should be irrigated with water, and the cultivars should be cultivated in proper time till the first fruit is usually not watered before sitting. When the soil is too dry, it can be poured with small water. When the first ear grows to the size of the walnut, it is necessary to top-up fertilizer in a timely manner. Each acre can be topdressed with 10-15 kg of urea or 5,000 kg of human waste. During the second and third layers of fruit enlargement, fertilizer should be applied separately to keep the soil intact. Dry to see wet. Irrigation is controlled after the beginning of winter, and water is usually poured every 10 to 15 days. To maintain balanced development of vegetative and reproductive growth, usually leave 4 to 5 spikes per plant, leaving 3-4 fruits per panicle. Pruning in time in the cultivation should be timely, removal of old leaves, diseased leaves and wipe the lateral buds. When the lower temperature is low, 2,4-D or tomato spirit can be used to facilitate fruit setting. Timely harvesting and ripening of tomatoes should be promptly harvested in order to facilitate the normal growth and development of other fruits on the plant. Fruits that have turned red after harvesting can be stored for 15 to 20 days at a low temperature of 2°C to 5°C. In order to enable the tomatoes to be listed on the National Day-Spring Festival, the white ripe fruit can be picked 3 to 5 days in advance and used for ripening after ethephon.
