There is a new method of production

In the winter and early spring seasons, it is possible to produce yam yellow by covering the open field with a black plastic film. This method requires only one ridge and can be harvested several times. Now its production technology is as follows: First, give enough root fertilizer. Before the cover is covered, 4000 kg of manure per acre, 30 kg of potassium dihydrogen phosphate and 10 kg of urea are applied per acre. Water is applied after fertilization, and then the roots are loosened. Second, the stent cover film. Before the film is covered, the weeds in the ridges are removed, and the soil is then covered with ridges. The thickness of the cover soil is about 5 cm, and the ridge height is about 30 cm. A bracket is inserted every 60 centimeters on the ridge edge, and the middle part of the arch is 45 centimeters high. After covering with a black mulch, it is pressed at the edges with 5 to 10 centimeters of soil. Third, picking yellow harvest. Harvesting can be arranged twice a year. If the first time before the Spring Festival, the next harvest time should be postponed from late March to early April. During this period, it should be resistant to high temperature and bad weather. When the temperature is high, it can be dispersed in the air at night. When harvesting glutinous rice, a piece of film should be peeled off and all membranes should not be removed.
