When is peanut control? When do you know the best time for peanut control? Recently, many farmers have consulted the techniques of controlling peanuts. The following is a brief introduction for everyone.
Peanuts do not control their free growth, which is easy to cause peanuts to grow too high and too dense, resulting in peanuts permeable to the wind, poor light transmission, long-term will cause unnecessary nutrient consumption, so that the fruit pods are not full, and production is reduced. However, the forcible control of peanuts will lead to premature aging of peanuts. Peanuts that have not matured peanuts will wither early, without the photosynthesis of peanut leaves, and the fruit pods will not be able to absorb sufficient nutrients. So how to avoid premature aging after peanut control?
The first is the choice of peanut control time. The control of peanuts should be based on the law of peanut growth, with a small number of times, the principle of gradual control. The best time for peanut control is that the first batch of pods has grown to have a small finger belly. When the second batch of fruit needles is shaped like a chicken mouth, the height of the peanut plants is 30-35 cm. best effect. Before the control of the agent, the soil should be kept moist. If the soil is too dry, the control agent can not be completely absorbed, and the inhibition of peanuts will be increased, resulting in a reduction in production.
Followed by management after the control. After the control is effective, the bactericidal drugs such as carbendazim can be sprayed evenly on the leaves, sprayed once every 15 days, and sprayed three times in a row to avoid premature aging of the peanuts.
Finally, it is the pre-harvest management. One month before the peanuts are received, the foliar fertilizer such as potassium dihydrogen phosphate can be sprayed on the peanut leaves, sprayed once every ten days, and sprayed twice continuously to ensure the normal growth of the peanut leaves. The photosynthesis of peanuts can also avoid premature aging of peanuts.
The above is all the main points of peanut control, welcome everyone to add more, the above content is for reference only. Still want to learn other peanut planting techniques? You can continue to pay attention to Hui Nong Network!
