The methods for the cultivation of soft yellow rice mainly include the tile method, the softening method of the bag soil, and the softening method of the grass cover. These methods have the disadvantages of high labor intensity and high cost. Compared with the conventional tile method, the use of black plastic film to cover the cultivation of glutinous yellow, cost savings of about 400 yuan per mu, and also has the effects of temperature, light, moisture, weeding and other effects. When the black plastic film is used to cover the yellow plant, the method of deep sorghum should be adopted. Before rooting, sufficient root fertilizer should be applied. Ventilation should be paid attention during the breeding process to avoid high temperature in the shed. In the event of continuous rain and high temperature, membrane ventilation should be removed at night to reduce the temperature and humidity and avoid rot yellow. In recent years, some localities have chosen the two-year-old vegetal 791 selected by the agricultural sciences of Pingdingshan City for experimentation. Compared with the glutinous rice cultivated by conventional corrugated cultivation methods, they cover the black cultivars after the harvest of green oysters from March to April and from November to December every year. Membrane cultivation of yellow, achieved a significant increase in production. I. Test methods After the harvest of leek, 120 kg of decomposed manure and 10 kg of decomposed dry poultry manure are applied every 40 m 2 , and the loose soil is then rooted. After fertilization, in order to kill the earthworm and gray mold fungus, 90% crystal trichlorfon 800 times solution plus 40% rust repellent 600 times solution root canal once. After the leek is harvested, firstly remove the rotten leaves and other debris on the rapeseed. When the leek sprouts grow to 2 cm high, the soil is covered with ridges. The thickness of the soil is about 6 cm, and the depth of the sulcus is 30 cm to facilitate the seepage of the sap. After the irrigation, the cover membrane is covered with a piece of bamboo every 60 cm along the vegetable culm, and the height of the small arch shed is about 50 cm. It is covered with 3 layers of black agricultural film and compacted along the edges. Before the film is covered, prepare a bamboo tube with a diameter of 6 to 8 cm and a length of 50 cm. Remove the inner section and place a bamboo tube along each side of the dish every 5 meters. Place one head toward the inside of the basket and the other outside of the shed. For ventilation in the shed. Long yellow to 12 to 15 days can be harvested. It takes a long time to age, and it takes 8 to 10 days to harvest when the temperature is high. Second, the results and analysis 1. Production situation. With the black plastic film covering cultivation method, the yield per hectare is 111.2 kg, and the yield per hectare is 104.2 kg. The former yields 7 kg more than the latter, and the per mu yield translates into an increase of 87.5 kg, an increase of 6.7. %. 2. Employment situation. When using pot-stem method to cultivate glutinous rice, 360 tile drums are used for every 40 square meters. Every day, tiles at the top of the tile drums need to be opened for ventilation and ventilation. When harvesting, the pots must be moved and finished, and labor intensity is high. When cultivar yellow is covered with a black plastic film, it is basically no longer used after the film is covered. Comparing the two, cultivation of 1 mu of glutinous yellow differs by at least 3 workers. 3. Investment benefits. The cultivation of black yam with the black plastic film covering method requires 4.2 kg of agricultural film for every 40 square meters and the cost is about 35 yuan, while the cultivation with tile drum method requires 360 watts for each 40 square meters, and the one-time investment is about 846 yuan. The black membrane can be used at least 4 inches, and the investment per acre is calculated as 110 yuan, while the use of tile can be calculated as 5 years and 20 inches. Each acre requires 528.75 yuan per mu and the difference is 418.75 yuan.
