Key Field Management Techniques for the Late Growth Stage of Corn
1 Remove field weeds and diseased or weak plants. With the widespread adoption of mechanized wheat harvesting, the shading of wheat straw and stubble reduces the control effect of herbicides, and weeds left in wheat fields also increase the difficulty of weed control. For plots where chemical weed control is ineffective and field weeds are abundant, timely

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.

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

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 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,

What are the precautions for growing peanuts with plastic film mulching
Based on my experience growing film-mulched peanuts in Haicheng City, the following issues need attention in peanut plastic film mulching: 1. Choose suitable plots. It is best to choose sandy loam soil with deep soil layers and strong water and fertilizer retention capacity. Do not choose low-lying, easily waterlogged plots, and strictly avoid continuous cropping or alternating cropping.
