How to identify peanut root rot? Recognizing the typical symptoms is key
Peanut root rot is most severe during the peak flowering and podding stage. It mainly damages the roots of peanuts. After a peanut is infected, yellowish-brown water-soaked lesions form on the root crown, and the diseased area gradually turns dark brown. In the underground part of the diseased plant, the main root becomes wet and rotted, the root cortex turns brown and rots, is easily peeled off and shed, and there are no lateral roots, or the lateral roots are few and short, with the main root looking like a rat's tail...

What are the high-yield cultivation techniques for summer peanuts?
Summer peanuts mostly refer to peanuts grown after wheat harvest. Their growth period is 30-40 days shorter than that of spring peanuts, and each growth stage is correspondingly shortened. Growth is fast in the early and middle stages, and temperatures are low in the late stage, which is unfavorable for pod development. Therefore, the following measures should be taken. (1) Select early-maturing, high-yield varieties. (2) Sow early by seizing the time. In spring, every day counts; in summer, every hour counts...

Key Technical Points and Fertilization Methods for Topdressing Summer Peanuts
Fertilization should follow the "two topdressings, one spray, four supplements" approach. Specifically: the two topdressings are, first, early topdressing before the peanut plants form a full cluster, with 10 kg urea, 15 kg diammonium phosphate and 10 kg potassium chloride; the second topdressing is at the early stage of young pod swelling, generally 10 kg urea per mu. The one spray is in the late growth stage, per mu...

Detailed Explanation of the Cultivation Technique of Interplanting Spring Peanuts with Sugarcane
Sugarcane originated in tropical and subtropical regions and was formerly limited to cultivation south of the Yangtze River. In recent years, through the unremitting efforts of scientific and technological workers, the sugarcane planting area in the Huang-Huai River basin has expanded year by year. During the planting process, the sugarcane stem cannot be used for high-temperature bud cultivation; if stems are used for bud cultivation, sugarcane cultivation will not succeed. To...

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...

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....

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....

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...
