How to avoid the death of cotton seedlings? You should know about cotton planting and harvest time!

In daily life, the use of cotton can be said to be very extensive, so the planting area of cotton is not small in our country, so how to avoid the death of cotton seedlings? Do you know the planting and harvest time of cotton?

I. the basic situation of cotton

1. The origin of cotton

Cotton is a plant native to the subtropics, also known as cotton fiber, which has the highest yield in China, the United States, India and other countries. The producing areas in China include Jianghuai Plain, Jianghan Plain, Southern Xinjiang Cotton area, North China Plain, Northwest Shandong, Northern Henan Plain, and Coastal Plain along the Yangtze River.

two。 The use of cotton

Cotton has high output and low cost, so it is suitable for making all kinds of clothes, furniture cloth and industrial cloth, skin care and wrinkle-resistant beauty products, honey plants and flower arranging materials, etc.

Second, how to avoid the death of cotton seedlings?

Generally, there are many reasons for the death of cotton seedlings, including diseases such as blight disease and mismanagement, among which there are three main points: first, unsterilized, second, excessive watering and fertilization, third, mistakes in sowing and pesticide spraying, and fourth, suffering from freezing injury. And if you want to avoid the death of cotton seeds as much as possible, you have to:

1. To understand the function of coated cotton seed

After coated with foaming acid, cottonseed has killed the bacteria attached to cotton seed, enhanced the disease resistance of cotton seed itself, and has a significant advantage over uncoated cotton seed. However, the disease resistance of coated cotton seeds has certain limitations, not a package of good luck. The germs transmitted by soil and external forces should also be prevented and controlled in order to ensure the early emergence of strong cotton seedlings.

two。 Do a good job of supporting application technology

Mainly to increase the application of rotten organic fertilizer, avoid partial application of nitrogen fertilizer to promote seedling growth, weaken cotton seedlings; match the nutrient bowl soil of cotton seedling bed, and spray pesticides on pot soil and cotton seedlings.

3. Relieving stiff seedlings and restoring cotton seedling growth

For drug damage, fertilizer damage caused by rigid, stagnant cotton seedlings, to use different agents to resolve, experienced growers can use their own, do not understand can consult experienced farmers or relevant agrotechnical personnel.

III. Cotton planting time and harvest time

Planting cotton at the right time is also helpful to increase production. The following is about its planting time and harvest time.

1. The planting time of cotton

In general, the sowing time of cotton is from April to May, in which cotton varieties with long growth period can be sowed in early April, and those with short growth period can be sowed late in late April.

Of course, the sowing time of cotton is different in different areas, so it should be determined according to the local climate and termination conditions.

two。 The harvest time of cotton

Cotton generally takes 75-100 days from budding to maturity, and the cotton harvest time varies slightly with different planting areas. Generally speaking, the florescence of cotton is from late July to early September in the provinces in the middle and lower reaches of the Yangtze River, from early July to early August in the provinces in the middle and lower reaches of the Yellow River, and from mid-July to early September in Turpan, Xinjiang.

The above is the introduction of some dead seedlings in cotton planting introduced by the editor of Tuliu.com. In addition, it is very important for cotton to get high yield and timely sowing and harvest, so we should pay attention to it.
