Detailed Explanation of Key Techniques for Mulched Cultivation of Spring Peanuts
The main pest from the seedling stage to the pegging stage is aphids. Control threshold: 1000 aphids per 100 hills; per 667 sq m, use 6-8 g of 50% pirimicarb or 20 mL of 40% omethoate, mix with 50 kg of water, and spray for control. Attention should also be paid to protecting natural enemies (ladybugs). When the ratio of ladybugs to aphids reaches 1:80-100, ladybugs can be used to prey on...

How to plant spring peanuts at a reasonable density? Key technical points on planting density
To achieve high yields of spring peanuts, six technical steps must be mastered: 1. Select excellent varieties. Good seed is the foundation for high yields, so varieties with strong resistance, high yield and high oil content should be used first. In recent years, trials have shown that "three-high" good varieties such as Shanyou 523, Shanyou 71, Yueyou 79, Guihua 21 and Wuyou No. 7. When planting, also...

Proper application of the four fertilizers is very important for spring peanuts, and the fertilization method must be mastered
Spring peanut cultivation with plastic film mulching has the advantages of heat preservation, moisture retention, fertilizer retention, improving the soil environment, ensuring uniform and strong seedlings, promoting growth and development, earlier maturity, and increased yield and income. It can usually increase yield by 20%-30%, and increase net income by 50-100 yuan per mu. 1. Fine land preparation and full-layer fertilization for peanut mulching...

What are the key points of fertilization techniques for spring peanuts?
Calcium can promote pod formation, reduce empty pods and increase the number of filled pods; applying calcareous fertilizer such as lime to acidic soil can also reduce soil acidity and benefit nitrogen fixation by root nodules. Therefore, calcareous fertilizer can improve peanut yield and quality. When peanuts are deficient in calcium, plant growth is slow, roots are thin and seedlings are weak, and the edges and surface of old leaves will show...

Spring peanut planting should emphasize increased phosphate fertilizer application
After spring peanut planting this year, there has been more rain, many overcast and rainy days, and high field humidity, which is favorable for the reproduction of peanut rust pathogen. Damage has already begun to occur. If measures are not taken in time to prevent and control it, peanut yield will be seriously affected. Peanut rust mainly damages leaves, but also damages stems, pod stalks and pod shells. Generally...

A Complete Analysis of the Key Points of Spring Peanut Cultivation Techniques
I. Fine land preparation and sufficient base fertilizer. For spring peanuts, choose sandy soil with relatively high soil fertility and convenient drainage and irrigation. Apply 150 dan of high-quality farmyard manure, 100 jin of compound fertilizer, and 2 jin of boron fertilizer per mu. After plowing and harrowing to level, open furrows with a bed width of 5.2 chi and a ditch depth of 0.6 chi, ensuring the three ditches are connected. II. Select...

How to grow spring peanuts for high yield? Mulch covering is the key
In Maoming City, promoting mulch-covered cultivation of spring peanuts allows planting half a month to a month earlier, extends the peanut growing period, and increases yield by 20%-30% compared with ordinary open-field cultivation of spring peanuts. When cultivating with mulch, focus on the following steps: 1. Sow early to extend the growing period. Mulch-cultivated spring peanuts can be planted earlier...
