Cotton Seedling Growth Management

Current

Cotton seedling

Because of the sharp rise in temperature,

Growth trend

Very soon.

Since the beginning of June, it has begun to enter the bud stage, so now it is an important period for cotton field management. Cotton growers should work hard, adjust measures to local conditions and promote control.

First, cultivating the soil without loosening and timely tillage and loosen the soil will not only reduce soil moisture in the middle and lower parts of the soil.

evaporation

It can also promote the release of available nutrients in soil and make cotton seedlings root developed and grow rapidly.

The permeability of soil can also inhibit the growth of bacteria in soil and reduce the occurrence of cotton diseases.

We should increase the number of times of cultivation as much as possible, and properly raise and widen the cultivation, close to the plastic film, and raise the quality of intermediate cultivation.

As the saying goes, "hoe is deep in an inch and top up once again."

That's the reason.

Two, early application of bud fertilizer to promote early cotton seedlings this year after the continuous rainfall in May low temperature, resulting in cotton seedlings weak and growing.

In recent years, because of the sudden increase in temperature, cotton seedling leaves increased and increased, branches elongated, and the ability of root absorption was better.

So it is recommended that we do this one time.

Bud

Fat, the early days due to weather and nutrition caused by weak seedlings, to promote their early onset, forming a prosperous potential.

According to the experimental data, most of the soil nitrogen and phosphorus were more abundant and potash fertilizer was less in the recent years, and some soils were seriously deficient in potassium.

Therefore, potassium fertilizer must be applied and the ratio of N, P and K to 3:1:3 is suitable.

Three, timely control of the cotton fields this year is due to the difference in weather conditions, and the difference is very large. We must adjust measures to local conditions and make seedlings suitable.

It is necessary to control the growth slowly, control the growth quickly, reduce the amount of energy a little, and control the whole plant.

Four. Timely watering.

cotton

It is difficult to master the time and method of watering during the middle growth period.

For cotton fields with good soil moisture conservation, no light irrigation can be applied.

For cotton fields with poor moisture conservation and poor moisture content, water should be watered in time for drought, but no water should be poured to avoid interplanting.

Timely watering is needed after watering.

Five, the main disease of pest control and cotton bud stage is Verticillium wilt.

The main pests in the bud stage are aphids, red spiders, blind beetles and cotton bollworms. Especially in recent years, the damage of the blind stink bug is particularly serious. We must pay attention to it.
