Rice film mulching

I. Description of the main contents and technical indicators The rice fields in mountainous areas have high altitude, low temperatures, and particularly slow spring return. The seedlings return to green after transplanting for a long period of time, with less tillering, weak seedlings, and a severely insufficient effective ear at the later stage. The low number results in low yield per mu. In 1998, the city arranged rice mulch film covering and cultivation trials in Emeishan and Mabian counties. The results showed that after transplanting, the transplanted seedlings were soon born with fast growth, almost no returning green period, and the highest seedling height was comparable to that of non-covered film. More than 50%, mu effective ear increase 15-20%, ear number and seed setting rate also increased by 5-10%, mu yield increased 65-110 kg, an increase of 15-30%. Technical indicators: (1) Select high-yielding combinations of mid-maturity or late-maturing hybrid rice. (2) Seeding rate and sowing time: 1.3 to 1.5 kg, sowing time is the same as in the local dam area. (3) The use of plastic floppy disk nutrient soil to add strong agent dry nursery, seedling transplanting. (4) Daejeon's one-time application of base fertilizer, Mushi quality manure excrement 15-20 Tam, urea 15 kilograms, superphosphate 25 kilograms, potassium chloride 5 kilograms. Daejeon presses 1.9 meters to open the car and open a good side ditch. The width of the box is 1.6 to 1.65 meters. The width of the groove is 0.25 to 0.30 meters. The depth of the groove is 0.15 to 0.20 meters. Each row is planted in 8 rows and the recession is 0.13 to 0.16 meters. 1.75 to 2.16 million litters per litter. (5) Field management does not need weeding, generally do not need to top-dressing, if found late de-fertilization phenomenon, can be used in the heading period before and after the use of 2-3 kilograms of urea converted into 50 times liquid foliar spray. Disease prevention and pest control are the same as ordinary cultivation. (6) The water in the field is always maintained in half ditch water from transplanting to milk ripening period. Second, the use of instructions 1. The technology is suitable for use in rice fields with an elevation of 700 to 1,200 meters. The higher the altitude is, the more significant the effect of the increase in accessibility is, while the effect of increasing production is not obvious in the low-elevation Pingba area, and no cover film is necessary. . 2. The stable field can not be too shallow and the water can not be on the car surface. Drainage begins during the milk ripening period. It is because the car surface has been hardened during harvest and people can stand on the surface of the car. 3. One-time application of base fertilizer to try to meet the full growth needs of rice. 4. A white ultra-micro film with a thickness of 0.004 mm and a width of 2 meters was selected to facilitate the hole-pushing and transplanting. After the harvest, clean the membrane in time to cause contamination with rabbit residue. Third, input and output, social and economic benefits, market prospects, etc. Each acre field requires 2.5 kilograms of ultra-micro, about 20 yuan, the whole field, open the car, covers more than 1.5 labor costs, total 15 yuan, saving more than 0.5 kg of seeds Save at least 2 hours of weeding and dressing, and save 100 cubic meters of water, and add up to 20 yuan per mu, and increase 100 kg of rice per acre. Calculate the increase in production per mu based on the current market price of 1.20 yuan per kg. 120 yuan, 100 yuan per mu net income. There are at least 200,000 mu of paddy fields above 750 meters above sea level. If this technology is used comprehensively, it can increase rice production by 20 million kilograms per year, increase production value by 24 million yuan, and increase net income by 20 million yuan. The economic benefits are extremely significant. The prospects are very broad. The promotion of this technology can greatly ease the contradiction between returning farmland to forests and the rations of people in mountainous areas, and can promote the smooth progress of returning farmland to forests and protecting natural forests. Therefore, its social and ecological benefits are also extremely significant.
