Peanut blooming control technology

In the period of high temperature and heavy rain, peanuts are prone to flourish. Once peanuts flourish, their vegetative growth will exceed reproductive growth, which is disadvantageous to the high yield of peanuts, so it is necessary to take measures to control the growth of peanuts in this period. So how to do it in detail? Let's take a look at the detailed introduction with the editor.

1. Reasons for controlling prosperity

In the peak growing season of peanuts, if not managed properly, it will lead to excessive growth of peanuts, only long stems and leaves without fruit, which will seriously affect the yield of peanuts. If the fertility and soil fertility are wasted, if it is not controlled in time, the plant will be too high, the stem will grow too fast, become weak and weak, and it is very easy to lodge, and because the nutrition will be transported to the stem and leaf growth, the pod will not have sufficient nutritional growth, resulting in not full growth and affecting yield. Therefore, it is imperative to control the growth, inhibit the vegetative growth of the plant, transform it into reproductive growth, make the fruit full and achieve the purpose of increasing yield.

2. Control boom time

The time of prosperity control is extremely important, too early will lead to a reduction in production, too late and can not achieve the correlation of prosperity control, so it is necessary to choose the right time to control prosperity. The best time should be when a large number of peanut fruit needles enter the soil, the height should be maintained between 30-40 cm, of course, the height control of different varieties is also different. Generally speaking, varieties with large fruit grains. The control height is about 40 cm, while the small fruit variety is generally controlled at about 30 cm.

3. Selection of control agents.

The commonly used control agent in production is paclobutrazol, which is because the large amount of paclobutrazol will seriously affect the growth of peanut pods, reduce its fruit shape and increase the thickness of the shell. But pay attention to two points: for a time, if applied prematurely, it will aggravate the disease of symptomatic leaves, make the leaves die and fall off ahead of time, and cause premature senescence of plants; in addition, paclobutrazol remains in the soil for a long time, which will also affect the following crops. Should not be used continuously.

4. Spray the exuberant

In the use of power control agent is to pay attention to a few points, first, many times a small amount, that is to say, control Wang should be carried out in several times, to avoid a spray overdose, generally not more than 40 grams per mu. Second, spraying should be carried out after the rain, spraying medicine within 6 hours of rainy weather, after the rain to spray again. Third, a small amount of neutral washing powder can be added to the medicine to enhance the absorption capacity of the leaves. Fourth, spraying should be carried out to the peanut growth node as far as possible, and can not be sprayed repeatedly.
