Common problems and prevention of groundnut peanut cultivation
The practice of peanut film mulching cultivation and proved repeatedly, it has obvious advantages than direct seeding. One is thermal insulation, the two is soil moisture conservation, the three is fertilizer conservation, four is soil improvement, five is weed eradication, six is labor saving, seven is early birth and early onset, eight is high yield and good quality. But, film mulching cultivated peanuts also often appear some technical mistakes, one is not timely, soil texture rough; two is the use of thick film, cause waste; three is insufficient soil moisture, sowing discomfort after the cover of the film is not homogeneous; four is the excessive or insufficient base fertilizer application, resulting in long or premature failure; five is not used herbicide or with the back cover film is strict, so weeds top thin film.
In order to give full play to the potential of increasing yield of plastic film peanuts, the following corresponding measures should be taken in the foundation work.
1. Fine whole. In general, the field of mulching cultivated peanuts with plastic film is generally determined. In winter, the soil should be tilled into the Kang soil. In winter, it is too late to turn the plough. After spring, it is necessary to turn the plough into the sun in time and then make a fine rake. It is necessary for us to make straight, flat, soaked and clean grass.
Two. Proper fertilization. The Rhizobium in peanut can fix part of the nitrogen in the air, but it can not fully meet the needs of the peanut for nitrogen fertilizer, and can not replace the demand for the phosphorus and potassium fertilizer. Therefore, a proper amount of fertilizer should be applied before the cover, 4000 kg of soil residue, 10 kg of urea, 45 kg of calcium superphosphate, 50-100 kg of grass and wood ash, or 10 kg of potash fertilizer.
Three, suitable for seeding. Before the peanuts cover the plastic film, soil moisture must contain moisture that ensures the germination of peanuts. When the soil temperature is stable through 12 degrees, it can be sowed. The general sowing date is in the middle of the April. Large seeds were sowed 16-18 kg per mu and sowed 8000-9000 caves. Small seeds were sowed 13-15 kg per mu and sowed 9000-11000 caves. 2 grains per point.
Four. It is safe to use medicine. Peanut and peanut must be sprayed before planting. For each mu, 100-150 ml, or acetochlor 50-75 milliliters, or 125-150 ml of water, or 50-60 kg of water should be applied to the soil surface before the cover film. It can also be used to kill herbicides, such as fine and stable, and grass can be used as a herbicide. When selecting herbicides, one is to breed the right way, the two is to dose accurately. In this way, a safe, economical and effective way can be achieved.
Five, choose the film. The plastic film covering peanuts is not suitable for thick film. Two, it is not advisable to use old membranes and film breaking. The thickness of the film should be 0.004 millimeter to 0.008 millimeter, or 0.014 millimeter. The width of the film depends on the width of the box. The cover film must be flat cover tightly. Each separate meters to prevent soil lamination, the wind will blow over or tear film.
