Common Problems and Prevention of Peanut Cultivation in Plastic Film

The practice of mulching cultivation of peanuts has repeatedly proved that it has obvious comprehensive advantages over open-air broadcasting. The first is heat preservation, the second is protection, the third is retention of fertilizer, the fourth is improvement of soil, the fifth is the elimination of weeds, the sixth is the provincial holiday, the seventh is premature birth, and the eighth is high yield and quality. However, there are some technical mistakes in film-covered cultivation of peanuts. One is that the preparation is not timely, and the texture of the soil is rough. Second, the use of plastic film is too thick to cause waste. Third, the lack of lyrics, and the emergence of unsuitable cover films is not uniform; The over- or under-fertilization of the base fertilizer causes madness or premature senility. Fifth, the herbicide is not used or the cover film is not used strictly to make the weeds break the film. In order to give full play to the potential for increased production of mulching peanuts, the following countermeasures should be taken in the basic work of sowing. First, fine soil preparation. Generally determined to take the film to cover the field of cultivation of peanuts, plowing soil should be plowed in winter, plowing in winter is too late, after the spring to promptly plowing the sun exposure, and then fine-tune the whole. It is absolutely necessary not to cover the membrane. Second, the amount of fertilizer. Peanut rhizobia can fix a part of the nitrogen in the air, but it can not fully meet the needs of peanuts for nitrogen fertilizer, but also can not replace the demand for phosphorus and potassium fertilizers. Therefore, the base fertilizer must be properly applied before cover film, and soil residue should be applied per mu. Fertilizer 4000 kg, urea 10 kg, 45 kg of superphosphate, 50-100 kg of plant ash, or 10 kg of potash. Third, appropriate planting. Before peanuts cover the mulch, soil moisture must contain moisture that will ensure that the peanuts germinate. When the soil temperature stabilizes through 12°C, it can be sown. The general sowing date is in mid-April. Large seeds per acre sowing 16-18 kg, sowing 8000-9000 points. Small seeds per acre sowing volume 13-15 kg, broadcast 90001-11000 points. 2 tablets per hole. Fourth, safe application of pesticides. Peanuts must be sprayed before cultivating peanuts after filming. Available per acre 100-150 milliliters of cable, or acetochlor 50-75 milliliters, or 125-150 milliliters, 50-60 kilograms per water, sprayed on the surface before the cover film. Can also be used to kill stable, cover grass and other herbicides. When herbicides are selected, one must have the right variety and the second must be accurate. Only in this way can we be safe, economical and effective. Fifth, careful selection of plastic film. Peanut mulch film, one should not use thick film, the second should not use the old film, broken film. The thickness of the selected film should be 0.004 mm to 0.008 mm microfilm, or 0.014 mm mulch film. The width of the film is determined by the width of the car. Cover the membrane when it is covered. Earth pressure membranes are used at each isolation meter to prevent blowing or tearing of the membrane when the wind blows.
