Mulch spring peanuts ready to broadcast "four off"

1. Select the soil: Peanut is drought-tolerant and resistant to inferiority, and prefers sandy loam with good permeability and large temperature difference between day and night. Plots of peanuts and legumes that have not been planted should be selected, and crops such as green onion, corn bran, and vegetable bran should be selected.

2, choose superior species: covering the mulch film can increase soil temperature, enhance the ability to protect the sputum, improve fertilizer utilization. In order to improve the planting efficiency, the mulching cultivation should choose the varieties of large and medium-sized fruit types with higher yield potential, higher yield and strong disease resistance.

3, timely sowing: there are often two misunderstandings in production: one is the early sowing period, because the temperature in the early spring is not stable, but the lack of seedlings and ridges, causing serious slanders. The other is to delay the sowing date, because the effect of mulching film can not be fully exerted, and the listing period is postponed accordingly, which will affect the income. Tests have shown that the sowing date of plastic film peanuts is generally about 10 days earlier than that of open spring peanuts, and April 15-20 is appropriate.

4. Appropriate density: The density of mulch spring peanut cultivation should not be too small or too large, and the small size will affect the yield. The rate of excessive single plant will decrease, the seeds will be wasted, and the yield will be reduced. In production, a double-row cultivation mode is usually used. The line spacing is 30 cm, the plant spacing is 15-18 cm, the mu density is about 10,000 points, two holes per hole, and the seed amount is about 17 kg.
