Technology of squatting seedlings of clear Peanut

Squatting seedling of peanut is an advanced field management technology of peanut, which can inhibit seedling stem and leaf growth and promote root development during crop cultivation, which can make plant growth strong and improve plant resistance and lodging resistance. So how does Kiyuko squat seedlings proceed? Let's take a look.

1. Qinggu is important

It can promote the growth of the first and second pairs of branches of the seedlings, the internodes are short and strong, promote the secondary branches to start early, clear the trees in time after the emergence of peanut seedlings, make the stem base of the seedlings exposed to the ground, contact the sun in advance, and change the wet and cold environment of the base of peanut stems. make the stems and branches grow early and quickly. It can also promote the early differentiation of flower buds, lay the foundation for high yield, improve the growth and development of root system, improve its drought and waterlogging resistance, and enhance its resistance to diseases and insect pests. At the same time, it can also reduce the harm of weeds, and the number of aphids at the base of peanut stem will be significantly reduced after clearing.

2. Qinggu time

Correctly mastering the time of clearing trees is the key to increase peanut production. If the trees are cleared too early, the resistance of the seedlings to the external environment is weak, the leaves will be easily burned by the sun, and the extension of the root system will be affected. If the trees are cleared too late, it will lead to thin lateral branches and long internodes at the base of the stem, which will affect the effect of clearing trees. It is best to clear the seedlings after the seedlings, according to the order of sowing and emergence.

3. Qinggu depth

Attention should also be paid to the depth of clear trees, which should not be too deep or too shallow, the cotyledons are not exposed to the soil surface, and the lateral branches and stem bases are also buried in the soil, which can not achieve the role of clear trees; too deep will expose the hypocotyls of seedlings, which can easily lead to seedling lodging and is not conducive to the normal growth and development of seedlings. Generally, after completing the seedlings, use a big hoe to hoe all over the land, and then use a small hoe to pick away the soil around the seedlings and expose the cotyledons.

4. Squatting time

Squat the seedlings for a period of time after clearing the trees, so that the seedlings can grow healthily and promote the secondary branching as soon as possible. The best time for squatting seedlings is 15-20 days, when the basal internodes of the seedlings have changed purple to green, and the secondary branching has been carried out.

The above is the peanut Qinggu squatting seedling technology introduction, hope to help you, is to know more related knowledge, please pay attention to us.
