How to cultivate peanuts with plastic mulch? Looking for methods
I. Pre-sowing preparation
1. Seed selection: Yuanza 9102, 8908, Yuhua 14
2. Sun-drying pods: sun-dry pods for 2-3 days before shelling
3. Mulch preparation: buy 60 cm micro-mulch film, 3-4 kg per mu
4. Underground pest control: (1) per mu use 3-4 liang of isofenphos-methyl or phoxim mixed with 0.5-1 kg of water and 20-30 kg of soil, broadcast before plowing; (2) per mu use 1 liang of isofenphos-methyl or phoxim mixed with 2.5 kg of water and 25 kg of peanut seeds.
II. Formula fertilization
According to the soil testing results of peanut fields in our county, on the basis of applying 1000-2000 kg of farmyard manure per mu plus boron, zinc and molybdenum fertilizers, fields with a yield below 200 kg per mu should apply 25-30 kg per mu of (15-10-15) formula fertilizer; fields with a yield of 250-350 kg per mu should apply 35-40 kg per mu of formula fertilizer; fields with a yield above 400 kg per mu should apply 40-50 kg per mu of formula fertilizer or other peanut special-purpose fertilizers.
III. Sowing and chemical weeding
1. Sowing time: sow with sufficient soil moisture and cover with film from late March to early April
2. Density: two rows per film, row spacing 1 chi, plant spacing 6 cun, two seeds per hole.
3. Chemical weeding: after sowing and before covering with film, apply 2-3 liang of 50% acetochlor per mu diluted with water and spray; or after emergence, apply 3 packets of gallant per mu diluted with water and spray; for fields with many nutsedges, apply 2-3 packets of Shalongqing or Bailongtong per mu diluted with water and spray (only wheat can be planted in the following crop)
IV. Field management
1. Film-breaking time: when peanut seedlings push through the soil, use three fingers or a blade to open a 1-1.5 cun hole.
2. Seedling clearing time: after emergence, when the main stem has two compound leaves unfolded, promptly clear the soil mound on the film holes so that the cotyledons are exposed outside the film.
3. Branch pulling time: when the peanut main stem has 4 compound leaves, pull out the lateral branches under the film
4. Vigor control: 30-40 days after flowering, for fields where plant height exceeds 1.5 chi and the canopy is dense with excessive growth, apply 1 liang of 15% paclobutrazol per mu diluted with water and spray.
V. Pest and disease control
1. Dead plant control: (1) choose disease-resistant varieties such as Yuanza 9102; (2) after full emergence and at early flowering, apply 3 liang of 40% carbendazim per mu diluted with water and spray.
2. Leaf spot control: at the early stage of disease onset, apply 4 liang of 40% carbendazim per mu diluted with water and spray.
