When is it good for peanuts to fight chlormequat chloride?

It is very important to control the vigorous period of peanut for peanut yield; However, when to control the boom, not everyone is just right, and there will be the same phenomenon of controlling the boom, some with high output and some without effect; So when to fight chlormequat chloride, the control effect is good, let's analyze this problem now.

Why does Humpty Dumpling need peanuts now?

In the past, when peanuts were planted, only some soil manure and phosphate fertilizer were put in the field. After the emergence of peanuts, farmers only need to weed, and there is no need to consider whether peanuts are flourishing or not. However, with the extensive use of nitrogen fertilizer, the problem of vigorous growth of peanut plants appeared. In the later stage, the vigorous peanut plants lodging and rotting, and the peanuts bearing little fruit, even rotting, seriously affected the yield of peanuts.

In order to control the growth of peanuts, farmers have come up with many ways. At the beginning, when the peanut plants show signs of vigorous growth, farmers will trample the peanut plants with their feet, causing certain damage to the peanut plants, thus slowing down the growth of the peanut plants. This has a certain effect, but it takes time and effort. After chlormequat appeared in the market, farmers generally adopted the chemical control method of spraying chlormequat.

Spraying chlormequat chloride, if the time is not well controlled, still can not achieve the effect of controlling the flourishing growth.

Farmers all know that spraying chlormequat chloride on peanuts to prevent lodging is conducive to increasing production; However, in the specific spraying process, the timing is wrong and the control effect is not ideal; With this experience, it is necessary to increase the spraying amount in the second year. Due to excessive dosage, a large number of leaves of peanut plants will wither and fall off, resulting in insufficient photosynthesis and affecting peanut yield. Some people will spray carbendazim and page hormones to remedy it, which will waste people and money and reduce production.

When is the best time to spray chlormequat chloride? Farmers in this area, their peanut plants are very short, but the yield is very high, and the shelling and nuts are as high as 600-700 kg per mu, which is estimated to be the highest in the country; When I exchanged experiences with them, I found that the soil where they planted peanuts was not fertile, but they sprayed chlormequat at a particularly good time.

Their specific methods are: peanuts bloom about 25 days after emergence, and they are sprayed with chlormequat chloride immediately after flowering; After spraying chlormequat chloride, the growth rate of peanut plants slowed down, but the roots still absorbed a lot of nutrients from the soil. Because plants grow slowly, they only need a small amount of nutrients, and most of the nutrients will be absorbed by the flower buds of peanuts, making peanuts stronger and stronger, laying a solid foundation for high yield.

When peanut injection was completed, it was found that peanut plants grew too fast. At this time, chlormequat chloride was sprayed again to inhibit the growth of peanut plants again. The benefits of doing so are obvious. If the growth of peanut plants is inhibited, a lot of nutrients will be concentrated on the needles of peanuts. With the guarantee of adequate nutrition, peanut needles will bear more peanut fruits, so that the planted peanuts can obtain high yield.

However, the control effect of farmers in some areas is not good. The reasons are as follows: only when peanuts are already growing vigorously will chlormequat chloride be sprayed to inhibit plant growth, which not only has poor control effect, but also loses the significance of spraying chlormequat chloride; Therefore, they can't achieve high yield by spraying chlormequat chloride.
