Does late growth control of peanuts have any impact on peanuts (Will growth control of peanuts affect yield)

As the saying goes, "Good children depend on good mothers, good crops depend on good seedlings", and "Good seedlings guarantee half the harvest". This fully demonstrates that in order to have a good harvest of crops, we must pay attention to cultivating good seedlings.

But at the same time, it also says, "We must strictly prevent tall and thin seedlings from growing too tall, and comprehensive prevention measures must be taken." In other words, crops must be controlled in a timely manner to prevent them from growing too tall.

In today's crop cultivation, people generally pay attention to the supply of fertilizer and water, as if fertilizer and water will lead to high yields. Indeed, to a certain extent, high crop yields are inseparable from large amounts of fertilizer and water, but at the same time, it also causes the crops to grow too long.

When peanuts grow too tall, nutrients are unevenly distributed, with most of the nutrients moving to the above-ground plants. However, peanuts are not a crop that bears fruit above ground, but underground. This will lead to malnutrition of the pods and reduced yields .

Moreover, because the above-ground part is too vigorous and the ventilation and light transmission are poor, pests and diseases will be aggravated, and problems such as lodging will occur, which will lead to a decrease in peanut yield.

Therefore, for peanuts growing vigorously in the land, we must pay attention to controlling the growth at the right time.

The purpose of controlling the growth of peanuts is to shorten the distance between the fruit needles and the soil; increase the leaf area, make full use of the light, and improve photosynthesis; prevent lodging and increase yield; effectively control vegetative growth and promote the transportation of photosynthetic products to the pods. Timely controlling the growth of peanuts can significantly increase yield.

1. When is the best time to control the growth of peanuts?

Peanut growth control is usually carried out during the flowering period. For example, spring peanut growth control here is usually carried out from mid-July to early August. Summer peanut growth control is usually carried out about 30 days after the beginning of flowering.

2. How to control the growth of peanuts?

At present, the commonly used method is to spray growth regulators to promote growth, prevent inversion and control vigorous growth.

3. What are the commonly used growth control agents?

Commonly used drugs for controlling the growth of peanuts include paclobutrazol, vinconazole, vinconazole, and chlormequat.

4. What impact does controlling the growth early or late have on yield?

If peanuts are controlled too early, it is easy to cause the plants to be too short and the leaf area to be reduced, resulting in lower photosynthesis, less photosynthetic products, smaller pods and lower yields.

If the concentration used is too high, not only will the plant height not reach a reasonable height, but it will also easily cause the fruit needles to be shallow in the soil and the pods to be small.

In our place, some people cut down peach trees and planted peanuts instead. As a result, because too much paclobutrazol was used in the peach fields, the flowers did not grow and only became a small black mass, twitching without growing.

Its leaves are the size of a fingernail, and the peanuts are as big as beans, but they are full and can't be peeled open. But the yield is too low to be honest, and no one is willing to buy them. Even if you make your own peanuts, the machine can't peel them enough - there are not enough.

This is the harm of controlling the growth of peanuts too early or too heavily, but controlling the growth too late is also not good.

What do you think is the purpose of controlling the growth of peanuts? Isn't it to control vegetative growth and promote reproductive growth? That is, to change the direction of nutrients, so that more nutrients are transported to the underground pods and less to the above-ground parts.

If you control the growth too late, the nutrients will go to the aboveground part. What's the point of spraying the growth control agent at this time? It can't change the height of the plant that has already grown too tall, nor can it extract nutrients and transport them to the ground. It has become a fact and cannot be changed. This is called "it's too late to mend the fold after the sheep have been lost".

Peanut growth control means spraying growth control agents on peanuts with a tendency to grow too long in the field to regulate growth, promote growth and prevent lodging, control growth, increase the rate of full fruit, and ultimately increase yield. However, controlling growth too early or too late will inevitably affect the growth of yield and lead to a reduction in yield .

How much the yield will be reduced depends on the extent of the growth of your peanuts. Different soils, water, fertilizer, varieties, density, etc. will result in different yield reductions.
