The practice of peanut mulching with plastic film has repeatedly proved that it has obvious comprehensive advantages over open-air broadcasting. However, there are some technical mistakes in the cultivation of peanuts covered with plastic film. 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 covering films is not uniform; It is the over- or under-fertilization of the base fertilizer that causes madness or premature senescence. The fifth is the absence of herbicides or the use of laminar membranes to make the weeds break through the membrane. In order to give full play to the potential for increased production of mulching peanuts, the following countermeasures must be taken in the basic work of sowing. Fine site 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, and then finely pounded. It is absolutely necessary not to cover the membrane. Appropriate amount of fertilizer. Peanut rhizobia can fix 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 amount of base fertilizer should be properly applied before the cover film, and soil 4,000 kg of slag, 10 kg of urea, 45 kg of superphosphate, 50-100 kg of plant ash, or 10 kg of potash should be applied per mu. Suitable for sowing. 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 13-15 kg, broadcast 90001-11000 points. 2 tablets per hole. Safe application. Peanuts must be sprayed with mulching peanuts before emergence after emergence. Available per acre 100-150 milliliter cable, or acetochlor 50-75 milliliters, or 125-150 milliliters, 50-60 kilograms of water per acre, 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. Carefully choose the film. Peanut mulch film, should not use thick film, old film, broken film. The thickness of the mulch film should be 0.004 mm to 0.008 mm microfilm, or 0.014 mil mulch film. The width of the film is determined by the width of the car. Cover the membrane when it is covered. Earthing membranes should be taken at intervals of 5 meters to prevent blowing or tearing of the membrane when the wind blows.
