About cotton cultivation
(i) Remove leaves. It is commonly known as "hitting the public branch." Leaves grow fast, consume more nutrients, inhibit the growth of fruit branches and affect the development of buds and bolls, at the same time cause poor ventilation in the lower part of cotton plants, easy to produce diseases and insect pests, so that buds and bolls fall off, so it should be removed in time. If the cotton plant grows too vigorously, it can also knock off the leaves and leaves under the fruit branches together, which is called "taking off the trouser legs" by the masses. When taking off the trouser legs, if the buds have appeared on the leaves, the top center of the leaves can be knocked off and reformed. (b) Scrubs. Commonly known as "wipe ears."

Control measures of Cotton aphids in the Yellow River Basin

On the 3rd, the average temperature is 2428 ℃ and the relative humidity is 55% and 85%, which is beneficial to the proliferation of "aphids".

Diagnosis and Control of Cotton Seedling Diseases
Diagnosis and control of cotton diseases at seedling stage there are many kinds of diseases in cotton seedling stage, but there are mainly two types of diseases: root disease and leaf disease. Root diseases often lead to rotting before emergence, rotten buds, root rot and stem base rot after emergence are the main causes of lack of seedlings and broken ridges in cotton fields, such as standing blight, anthracnose, red rot, quenching and so on. The leaf disease is harmful to the cotyledons, true leaves and stems of cotton seedlings, and when it is serious, the top of the stem and leaves wither and fall off, such as black spot, brown spot, cotton seedling blight, stem blight and so on.
