Detailed Explanation of Key Techniques for Film-Mulched Spring Peanut Cultivation
Film-mulched cultivation of spring peanuts has the advantages of keeping warmth, preserving moisture and fertilizer, improving the soil environment, ensuring uniform and strong seedlings, promoting growth and development, advancing maturity, and increasing yield and income. It can generally increase yield by 20%-30% and increase net income by 50-100 yuan per mu. I. Fine land preparation

How to treat peanut seeds before spring sowing? These points you need to know
The farming proverb says that around Grain Rain, you plant melons and sow beans, and the busy spring plowing work is about to begin. Today let's discuss with fellow farmers the methods for treating peanut seeds before sowing, to lay the foundation for uniform emergence, full stands, and strong seedlings. First, select good seeds and superior seeds, and classify the seeds.

Occurrence Patterns and Control Methods of Peanut Spider Mites
Peanut spider mites occur commonly in Zhaoyuan City, mainly the carmine spider mite (Tetranychus cinnabarinus) and the two-spotted spider mite (Tetranychus urticae), among which the carmine spider mite has the highest occurrence density and causes the most severe damage, while the two-spotted spider mite affects a smaller area, but in recent years the two-spotted spider mite has shown an upward trend in Zhaoyuan City. In recent years, peanut spider mites

How to prevent and control pests and diseases in autumn peanut cultivation
The main diseases of peanut include leaf spot and rust. For leaf spot, spray pesticide in time at the early stage of disease onset to prevent and control the disease. Use 75% chlorothalonil + 70% thiophanate-methyl at 1000-1500 times dilution; or 30% copper oxychloride + 75% chlorothalonil at 1000 times dilution, spraying 2-3 times, once every 10-15 days,

Adopting the "three protections" technique in peanut cultivation significantly increases yield
1. Preventing excessive vegetative growth. For peanut fields with relatively high soil fertility, good water and fertilizer conditions, and vigorous plant growth, when growth is too vigorous and excessive vegetative growth occurs, spraying hormones, namely plant growth regulators, can inhibit vegetative growth, promote reproductive growth, and coordinate the relationship between vegetative growth and reproductive growth.

How to chemically control weeds when growing peanuts
Peanut is one of the main cash crops in Yanshan, and in the cultivation process the most labor-intensive and time-consuming task is weeding. The weeds that cause relatively serious damage on peanut land include grasses such as crabgrass, foxtail, Chinese sprangletop, nutsedge, goosegrass and barnyardgrass; broadleaf weeds include thistle

How to regulate peanut flowering with chemical control? Practical measures explained in one article
Yield-increasing ling has the effect of promoting the movement of nutrients within the plant, accelerating cell differentiation, preventing shedding, preserving flowers and fruits, promoting grain filling and early ripening. During the peanut flowering period, spray the leaves 1~2 times with a 10~30×10-6 solution; the rate of blighted pods is reduced by 10%~20%, and per 667 sq m

How to use peanut meal fertilizer correctly? A detailed guide to its use
1. Put peanut meal powder into water and let it decompose in an oxygen-poor environment. It can be used after 2-12 months. The longer the time, the higher the degree of decomposition and maturity, and the less likely it is to burn plants. The ratio of peanut meal to water is about 1:15. When using, the liquid fertilizer must first be diluted with water; the ratio of liquid fertilizer

How to grow peanuts for high yield? Getting sowing right is key
1. Improved variety selection: choose high-quality, high-yield peanut varieties such as Huayu No. 17, Huayu No. 16, 8130, etc. 2. Formula fertilization: growing peanuts absorb nitrogen, phosphorus and potassium in a ratio of 1.1:1:1.1. According to this ratio, for fields with ordinary yield, apply per mu 2000 kg of high-quality farmyard manure, 50 kg of superphosphate, 15-20 kg of compound fertilizer, 10 kg of urea, 2-3 kg of potassium dihydrogen phosphate, and 1 kg each of borax and zinc sulfate. Mix the farmyard manure, superphosphate and potassium dihydrogen phosphate and broadcast them during land preparation; apply the other chemical fertilizers in the furrows when ridging.

How to prevent and control peanut bacterial wilt? Detailed explanation of prevention and control methods
1. Symptoms. Peanut bacterial wilt mostly begins to develop around flowering, but the disease is most severe during the peak flowering and pegging stage, and the condition eases somewhat after pod formation. The most notable feature of its symptoms is: the aboveground leaves of diseased plants wilt rapidly, the vascular bundles in the underground roots turn brown, and when the root crown is cut lengthwise, in moist conditions a cloudy bacterial ooze can be squeezed from the cut. If the diseased root crown section is suspended and immersed in clear water, a smoky cloudy liquid can be seen gushing from the cut, which is a reliable basis for confirming this disease. Usually the chlorophyll of the wilted leaves has not yet been destroyed, and although the leaves lack gloss, they still remain green, hence the name bacterial wilt.
