What to Do About Seed Rot in Spring Peanuts? Detailed Explanation of Causes and Control Methods
Symptoms: After spring peanuts are sown and before emergence, seed rot often occurs, with severe cases reaching 10%-20%, causing varying degrees of missing plants and broken rows. Causes: Poor seed quality or improper storage, or overly long storage periods; low-lying geothermal areas, heavy clay soil, poor soil texture, high soil water content, long emergence time for seeds, poorly firmed seedbed preparation, affecting...

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...

Good results with plastic film mulching cultivation of spring peanuts
Applying film mulching cultivation technology in peanut production can raise temperature, ensure full stands, retain water and preserve fertilizer, thereby achieving the goals of increased yield and income. In 2002, the author conducted a comparative experiment on film mulching cultivation of spring peanuts, achieving a plot yield of 402 kg per mu, a field yield of 367 kg per mu, and...

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...

Detailed Explanation of Key Points for Plastic Film Mulch Cultivation Techniques for Spring Peanuts
Anxi County has promoted plastic film mulch cultivation techniques for spring peanuts. Under similar conditions, yields are generally 15-20% higher than open-field cultivation, and Aspergillus flavus disease is reduced, peanut quality is improved, and good benefits are achieved. The cultivation techniques are as follows: 1. Variety selection: Choose "Shanyou 71," a variety with strong disease resistance, good waterlogging tolerance, and suitability for paddy fields with good fertilizer and water conditions...

Eight Precautions for Film-Mulched Cultivation of Spring Peanuts
Applying film-mulching cultivation technology to peanut production can raise temperature, ensure full stands, retain water and preserve fertilizer, thereby achieving increased yield, higher income and giving a head start on the season. In 2002, our institute conducted a comparative trial of film-mulched cultivation of spring peanuts, obtaining a plot trial yield of 402.75 kg per mu and a field yield of 367....

High-yield technique for large-scale film-mulched spring peanut sowing with pod sowing, moisture borrowing and dry sowing
Pod sowing with film mulching is an effective measure for early sowing of spring peanuts by borrowing soil moisture, ensuring full stands, resisting drought and increasing yield. The Agricultural Technology Extension Center of Linmu County began trials and demonstrations in 1987, and from 1992 to 1993 the implemented area reached 8,520 hectares, with average unit yields reaching 3,982.5 kg/ha and 4,057.5 kg/ha, increases of 13.9% and 16....

How to prevent and control seed rot after sowing spring peanuts
After sowing spring peanuts and before emergence, seed rot often occurs, with severe cases reaching a rot rate as high as 20%, causing missing plants and broken rows to varying degrees. Causes of seed rot: poor seed quality or improper storage, or too long a storage period; low-lying terrain, heavy clay soil, poor texture, and high soil water content, resulting in a long emergence time for seeds; poorly consolidated seedbed preparation, which affects the...

Common Problems of Greenhouse Eggplant in Early Spring and Their Control Methods
In the early spring season, when temperatures are low and light is weak, greenhouse eggplant often shows various abnormal conditions. The common problems and their control are described below: 1. Stunted seedlings In the early spring crop, eggplant often shows stunted seedling symptoms at the seedling stage, such as small leaves, dark green color, thin stems and few roots. After transplanting, such seedlings recover slowly, grow weakly, and...

Detailed Explanation of Spring Planting Time and Methods for Cherry Trees
Currently, in protected cultivation of sweet cherries, the main tree forms are the natural open-center form, the improved central-leader form, the central-leader stratified form, and the slender spindle form. The natural open-center form has a trunk height of 30-40 cm, 3-5 main branches, each main branch with 6-7 side branches, and an angle of 30-45 degrees between the main branches and the trunk. Tree height is controlled at 1.5-1.8 m, ...
