How to grow autumn peanuts for high yield? A detailed explanation of the key planting techniques
Peanuts are very popular in China, so nowadays peanuts are basically grown all year round in China. And right now is exactly the time to plant autumn peanuts, and the regions suitable for growing autumn peanuts have been busy one after another. When growing autumn peanuts, a high yield is what many people hope for. So how should autumn peanuts be grown to achieve a high yield? Below, the editor brings you the high-yield planting techniques for autumn peanuts. Let's take a look!
1. Leveling the land
The peanut is a deep-rooted crop, and its roots are generally distributed in the soil layer. Therefore, we must first choose a soil suitable for the growth of autumn peanuts, ensuring that the soil layer is deep and the tillage layer is loose and soft, which is conducive to the peanut roots penetrating deep. Then plow the soil deeply to about 22 cm, which can generally be done half a month in advance. Plow the soil deeply, break up the clods and level it, improve the soil structure, and enhance soil quality. Then cultivate in beds to increase the light-receiving area of the peanut plants and keep the soil temperature warm. Keep the bed height at about 12 cm to ensure the normal growth of autumn peanuts.
2. Applying sufficient base fertilizer
The base fertilizer for autumn peanuts is generally mainly fully decomposed farmyard manure, combined with an appropriate amount of phosphate fertilizer and plant ash and other materials. Autumn peanuts usually enter the flowering stage about three weeks after full seedling emergence. The vegetative growth period is generally not longer than that of spring peanuts. Moreover, autumn peanuts are generally sown in the hot and rainy season, and this environment will accelerate the decomposition rate of fertilizer, making it easy to consume, so it is essential to ensure sufficient base fertilizer is applied. Otherwise, during the early growth stage, autumn peanuts will show poor growth due to lack of nutrients. Under normal circumstances, apply about 3000 kg of farmyard manure and about 20 kg of superphosphate per mu, combined with an appropriate amount of plant ash, peanut bran, etc.
3. Controlling the seeding rate
The growth period of autumn peanuts is not very long, and the productivity of a single plant is also relatively poor. Therefore, if you want a high yield, you can only rely on the population, and at the same time maintain good ventilation and light penetration to improve the productivity of individual plants. So autumn peanut planting should mainly adopt double-row, double-seed planting, ensuring a sufficient number of plants per mu and enhancing the planting advantage of the marginal effect. For double-row, double-seed planting, make beds about 80 cm wide, with furrows about 35 cm. Control the average row spacing at about 40 cm, and the distance between sowing holes at 15 cm, sowing about two seeds per hole.
4. Sowing time
Because autumn peanuts are sown in autumn and harvested in winter, the sowing period is relatively strict. If sown too early, the seeds will be in a high-temperature and high-humidity environment, the stems and branches of the seedlings will be slender and weak, and weak seedlings are very likely to form, with relatively poor disease resistance and susceptibility to premature aging. If sown too late, then in the late growth stage of the peanuts the temperature will drop, which has a very great impact on the growth of the peanut pods, leading to a decline in yield. Therefore, we must adjust the sowing time according to the different growing regions, but under normal circumstances, the suitable sowing period for autumn peanuts is generally the period from the Beginning of Autumn to the End of Heat.
The above is a brief introduction to the high-yield planting techniques for autumn peanuts. That's all for today's introduction. This article is for reference only, and I hope it can help everyone!
