The latest course of High-yield planting techniques of Autumn Peanut

Peanuts are welcomed by many people in our country, so there are basically people growing peanuts in our country all the year round. And now is the time to plant autumn peanuts, some areas suitable for planting autumn peanuts are also busy one after another. When planting autumn peanuts, high yield is what many people hope. So how to plant autumn peanuts in order to achieve high yield? The following editor brings you the high-yield planting techniques of autumn peanuts, let's have a look!

1. Formation of land

Peanut is a kind of deep-rooted crop, and the roots are generally distributed in the soil layer. Therefore, we should first choose a soil suitable for the growth of autumn peanuts, to ensure that the soil layer is deep and the tillage layer is soft, which is conducive to the deep roots of peanuts. Then turn the soil about 22 centimeters deep, which can be carried out half a month in advance. Rake the soil deeply and rake it flat, improve the soil structure and improve the soil quality. Then do border cultivation to improve the light area of peanut plants and keep the soil temperature. The height of the border is maintained at about 12cm to ensure the normal growth of autumn peanuts.

2. Apply sufficient base fertilizer

The base fertilizer of autumn peanuts is generally based on fully mature farm manure, combined with an appropriate amount of phosphate fertilizer and plant ash. Autumn peanuts usually enter the flowering stage after about three weeks of full seedling. The time of vegetative growth is generally no longer than that of spring flowers. And the sowing time of autumn peanuts is generally in the high-temperature and rainy season, this environment will accelerate the decomposition rate of fertilizer, easy to consume, so it is necessary to ensure that sufficient base fertilizer is applied. Otherwise, autumn peanuts will have poor growth due to lack of nutrition in the early growth stage. Under normal circumstances, each mu is generally applied about 3000kg farm manure, calcium superphosphate 20kg, and then with the right amount of plant ash, peanut bran and so on.

3. Control the sowing rate.

The growth period of autumn peanut is not very long, and the productivity of individual plant is also poor. Therefore, if you want to be high-yielding, you can only rely on groups, and also maintain good permeability and improve individual productivity. Therefore, the planting of autumn peanut should be based on double-row and double-grain planting to ensure that the number of plants per mu is sufficient and improve the planting advantage of marginal effect. Double-row and double-grain planting should make a border with a width of about 80cm and a furrow of about 35cm. The average row spacing is controlled at about 40cm, and the distance between seeding holes is at 15cm, and each seeding hole is about two seeds.

4. Sowing time

Because autumn peanuts are sown in autumn and harvested in winter, the sowing period is relatively strict. If the seeds are sown prematurely, the seeds are in an environment of high temperature and high humidity, and the stems and branches of the seedlings are thin and weak, which is easy to form weak seedlings, poor disease resistance and premature senescence. If sowing is too late, then the temperature decreases in the late growth stage of peanut, which has a great effect on the growth of peanut pods, resulting in a decrease in yield. Therefore, we have to adjust the sowing time according to different planting areas, but under normal circumstances, the appropriate sowing time for autumn peanuts is usually between the Beginning of Autumn and the End of Heat.

The above is a brief introduction to the high-yield planting techniques of autumn peanuts. That's all for today's introduction. This article is for reference only. I hope it can help you all.
