Dianchi Lake Construction 1. Site selection: Dianchi Lake is to be selected from the headland, deserted land, waste pits, and saline-alkali lands and depressions where there is sufficient sunlight and there is no shaded trees. 2. Material preparation: 5 tons of lime, 5 tons of cement, 30 tons of sand, 8 square meters of film, 800 square meters of 50 centimeters, 70 centimeters, and 5 centimeters of prefabricated blocks with a thickness of 5 centimeters. The total construction cost per mu is 4000~ 5000 yuan. 3, build the pool. 1 Digging the pool: Use an excavator or artificial, the depth of the pool is 60 cm, and the slope of the pool wall is 60 degrees. 2 hammer at the end of the gang: lime will be thrown into the bottom of the pool, with rotary plough plow 2 to 3 times, depth 20 cm, after mixing the earth ash, the bottom level of the pool with a mechanical compaction, with 3:7 lime soil pool Wall compaction compaction. 3 film: After the bottom of the hammer, use a film to lay the bottom of the pool and the wall of the pool. 4 bottom: after laying the film, use 2 to 3 cm thick concrete to wipe. 3 ramp plate: The inclined plate is ready to stand on the pool wall, cement will be used to wipe the seams, so that Dianchi is ready. Site Preparation Fertilizer 1 and Shop Straw: Before planting, plant wheat straw, corn stalks or weeds into the pool with a thickness of 30 to 40 cm. Use 1.25 to 15,000 kilograms per mu and about 25 acres of crop straw. 2. Fertilization: Before dumping, 5,000 kg of earth-fertilizer, 75 kg of diammonium phosphate, 50 kg of potassium sulfate, and 20 kg of urea should be mixed with the cover soil and uniformly covered on the straw. The thickness is about 12 cm. Selection of planting and planting selection: Shallow water planters should choose small early maturing varieties such as Jinan Bailian, Elian IV and Wuhao. Seedlings are generally excavated before being planted. Selecting the whole plant that meets the characteristics of the species and has a sub-fungus, the sub-flies must grow in the same direction, so that the lotus whip extends regularly. Be careful not to injure the terminal buds during digging. Seedlings are generally cut at half an inch after the second quarter, and should not be hand rubbed to prevent the mud from pouring into the borehole to cause bad species. After digging, spray 400 to 500 times of 50% carbendazim solution to the seedlings and prepare for use after one day of boring to prevent corruption. Excrement: In the Qingming to Guyu drainage, do not be too late, with about 300 kg per mu, row spacing is 150 to 200 cm, spacing between 60 to 100 cm. Excretion method: According to the prescribed row spacing, the head is buried 12 to 15 cm deep in the straw, and then the section is slightly tilted on the water in order to use the sun to raise the temperature and promote budding. There are many ways to drain cockroaches. There are several lines in one direction and several lines are relatively arranged. The lines are arranged in a triangle to each other, so that the lotus whips are distributed evenly to avoid crowding. When planting, all four rows of buns are required to be headed. In the pool, lest the whip protrude out. After drainage, timely irrigation, water depth of 4 to 5 cm. Field management 1. Weeding, picking leaves, and picking flowers. Before the lotus leaves are sealed, weeds are combined with fertilization, and weeds are then stuffed into the mud below, as fertilizer. After about one month of colonization, the floating leaves gradually withered and should be removed to allow sunlight to penetrate into the water to increase the water temperature. When there are 5 to 6 leaves, the lotus leaf is lush and has been sealed. The ground floor early oysters have begun to sit and are not suitable for weeding. So as not to hurt your body. Weeding should be done on both sides of the leaf. For the purpose of collecting alfalfa, Dianchi Lake, flowering seeds consumption of nutrients, there should be flower buds occur when the flower stems meandering, can not be broken, so as not to cause rain by the invasion of stomatal rot. 2, fertilizer fertilizer lotus fertilizer, fertilizer is generally based on basal fertilizer, basal fertilizer accounted for about 70% of the total fertilization, top dressing fertilizer accounted for about 30% of the whole period. Rows of dense, early harvest fertilization and more. Base fertilizer has about 5000 kg organic fertilizer per acre. Top dressing is divided into two times. The first time, 6 to 7 leaves are produced in lotus root. When the leaves are growing vigorously, 1000-1500 kg of manure or 10 kg of diammonium phosphate is applied per mu. 10 kilograms; the second time at the beginning of the scarring, it was called "recruiting manure," and 50 kilograms of anaerobic manure was applied. Before each fertilization, shallow water should be allowed to allow the fertilizer to be inhaled into the soil and then poured to the original depth. After topdressing, pour water and wash the lotus leaves. If there is not enough fertilizer, you can chase 3 yuan compound fertilizer 15 kg/mu. 3, water level adjustment Tian Lu in the bud after more than 10 days to bud stage to maintain shallow water 4 to 7 cm, in order to increase soil temperature, promote germination. With vigorous growth of the leaves and branches, the water layer was gradually deepened to 12-15 cm until the time of sitting. A shallow water level of 4 to 7 cm should be placed one month before harvest to promote scab. 4. Turning hoe, also known as â€œback è—• , , , , , , , , , , , , , , , , , , è—• è—• è—• è—• ç”Ÿé•¿ ç”Ÿé•¿ ç”Ÿé•¿ ç”Ÿé•¿ ç”Ÿé•¿ ç”Ÿé•¿ ç”Ÿé•¿ growth rapidly, when the leaves off the edge of the pool 1 cm, at any time near the pool side of the è—• æ‹” æ‹” head to the pool, so that the distribution of scab , Growth period of 2 to 3 days, slow growth, 7 to 8 days, a total of 5 to 6 times. The bread is very tender. When you turn around, you will hold the festival together. After turning your head, press the soil again. Transfers should be made before and after noon to avoid breaking. 5. Disease prevention and control The main disease of lotus root is corruption caused by Fusarium. Control methods: Liquify with lime prior to drainage. Use 50-70 kg of lime per acre. Place the quicklime evenly into the pool with water. Use lime to prevent and control the disease. The main insect pests are aphids and Spodoptera litura, and aphids can be controlled with pesticides such as imidacloprid and quail. Spodoptera litura can be used to prevent and treat pesticides such as pyrethroid pesticides, caspase, card dead grams, and vegetables. 6, timely harvest into October, you can pick at any time according to need. When picking, you can grab it and pull it out slowly. It is quick and easy, and you can collect more than 400 kg per person per day.
