Non-pollution Yellow Rice High-yielding Cultivation Technique

The bright yellow color, unique flavor, refreshing taste and rich nutrition make it a delicious dish on the winter table. The cultivation of glutinous yellow refers to the cultivation of leeks rooted in open fields, followed by multiple frosted roots during the later period, and in winter, the roots of leeks are transferred to protective facilities such as sorghum and Yangshuo, and the stored yam is used to produce fresh yam under low light conditions. At the current stage of preparation for the cultivation of Scutellaria root, the author will summarize the relevant technical details for the reader's reference.

1. Cultivating roots Breeding robust roots is the basis for the production of Zhihuang, which is related to the yield and quality of Zhihuang. General use Pingyi 4, Xueyu Wang and 791 and other cold-resistant, high-yield disease-resistant varieties, live in the field before and after the summer live or wheat intercropping. Application of base fertilizer before sowing, pouring a good bottom water, fine soil preparation, about 2.5 kilograms per acre, spacing the rows by 20-23 cm, spreading the seeds evenly in the ditch, and using a fur coat to sweep a thin layer of soil , Lightly step on it again, then pour the first time the water, the ground see dry see wet when pouring the second time the water, until the ground is not dry when pouring the third time the water, that is, "not afraid of the second water night, three waters to catch up."

Before the beginning of autumn, generally do not top-fat, to prevent excessive growth or rot, to pay attention to water pouring, cultivating grass. After the beginning of autumn, it began to top-dressing and made roots. The first Mu recovery urea 12.5 kilograms or cake fertilizer 50 public

Jin, Bai Lu before and after the second application of fertilizer, acres of urea 20-25 kg. Throughout the growing period, we must diligently chop up weeds, cut less or cut them, in order to build strong roots. After the beginning of the winter, the dead leaves will be removed before the small snowfall, and the roots will be used as spare.

2. Prepare to choose lee, sunny, flat terrain, and high-dry plots (also in the courtyard). Dig along the east-west direction. The width is 3-4 meters wide and 1.25 meters deep. The length can be determined according to the number of roots. It is generally 12 meters long and is divided into 7 small bowls. The soil at the bottom of the Loudi should be moisturized and drained. The inner walls of the earthworms should be levelled and the south side of the bottom should be slightly higher than the north side to facilitate watering. After the excavation is completed, the roof is covered on the north side, and the width is half of the width of the girder to facilitate lighting. The top of the plot is 10-13 cm thick corn stalks, covered with mud, and the front edge is 33 cm above the ground, with a low slope at the top of the south and north, and immediately afterwards, the grass cover is covered.

3. Pick the roots and cut the roots of the roots, sort out the roots, and remove the roots and roots. Select the strong roots to align the upper ends of the stems and trays and bundle them into a 33-50 cm square bundle. Place the bundled roots firmly at the bottom of the raft, and use the roots to squeeze the gaps together. Piled up between the small piles of soil, waterproof collusion. It is possible to use three tiles on the south side of the monastery to form a circular waterway leading to the interior. When watering like this, it is not necessary to expose it. Generally after the small snow into the flood, after the first pouring a small amount of water, the depth of the root is 1/3 of the height, will be tamping the real. After 1 to 2 days, pour 1 more water. The water depth is better than the roots. After the water infiltration, the finely chopped horse dung is evenly sprinkled on the root of the alfalfa, with a thickness of 10-13 cm. The use of iron clams to make real, and then dry dry loquat leaves, wheat straw and other straw cover 10-13 cm thick, slightly thicker around the cover. This will allow the roots to germinate evenly. Finally cover your mouth with straw.

4, after the management of the lotus root into the water generally do not water in order to increase the temperature. Relieve during the day and cover at night. After the exposing ceremony, a layer of banquets should be built to prevent the invasion of the cold wind. After 4-5 days, the temperature of horse manure fermentation is controlled at 35-40°C. If the temperature is too high, some coverings must be removed. The middle and surrounding coverings can also be exchanged to ensure that the temperature within the manure is even. About 10 to 12 days later, when the shoots are 5-6 cm high, the temperature will rise rapidly. It must be strictly controlled below 48°C and all coverings should be gradually removed. Do not use buds when you excrete.

After starting the dung, put a small amount of water first and cover it for 2-3 days. Afterwards, the time for exposing the clams will be from short to long, from 2 hours to 6 or 7 hours per day, and attention will be paid to rainy days. Every afternoon, the hoeing time is controlled when the leeks begin to freeze. The watering time is controlled when there is no dewdrop on the leaves in the morning, and it is carried out when the leaves are no longer in the noon. However, the amount of water should not be too large to prevent rotten leaves from pouring every 5-6 days.

5. Harvesting and post-cutting management 30-40 days after entering the crop, that is, harvesting the first crop after about 20 days after excreting. At the time of harvest, first put a board on the board, step on the board, and harvest at l cm above the stem disk. Do not injure the board. The first board will produce about 100kg per barrel, the second board will be 50kg, and the third board will be 25kg.

After harvesting the first crop, the sun will cover for 2-3 days, then stay up late for 3 to 5 days. After that, the management will be the same as the first, but only a small amount of fertilizer will be applied after watering. After reaping 3-4 days, before and after the vernal equinox, dig out the roots of the alfalfa, plant a field with 23-26 cm spacing and plant the field with a spacing of 1-2 cm. The depth of the alfalfa root is lower than that of the ground. Compaction. Before and after the light snow, the roots can be used again for two to three years.

If necessary, a stove can be produced on the side of the oysters, and the tobacco can be introduced into the oysters to be heated and cultivated. The growth period can be shortened by about half.

During the growth period of yellow peony, onions and onion flies will harm the seedlings. In addition to avoiding the use of organic fertilizers that are not decomposed, they may be treated with drugs as appropriate.
