< p > the temperature, light, water and fertilizer condition of cotton growing in Anxiang, Hunan is suitable, and the pplanting date of cotton is earlier. At present, cotton grows better.

The average height of the local cotton is 88.7 centimeters, which is 19.6 centimeters higher than that of the same period last year; the fruit branch is 14.6, increasing by 3.8; the boll 1.8 has increased by 1.74; the young bell has 7.4, increasing 6.8; the bud 51.1 has increased 23.6; the flowering 1.4 has increased the number of 1.4 seeds; the abscission has been achieved; the total fruit number has been increased, and the rate of abscission has decreased.

< p > the average growth rate of local cotton is better than that of last year, and the number of plant height, fruit branch and bud number has increased significantly over the same period last year.

There are 16.2 branches, 2 bolls, 60.9 bud, 1.5 flowering, 75.6 total fruit, and 3.04% abscission rate. Two type seedlings account for about 40% of the total number, two centimeters, fruit branches and seeds, bell shaped seeds, bell buds, bud buds, flowering flowers, total fruit nodes, and shedding rate. About 30% of the total seedlings belong to waterlogged cotton. This year, a group of seedlings accounts for about 30% of the total, mainly from plastic mulched cotton planted before May 25th, with a height of 102 cm and fruit.

< p > main characteristics of current cotton growth: < /p >

< p > 1, the growth process is fast.

Local cotton blooms in large areas around July 8th, and the growth process is earlier than last year.

This is mainly the environment of high temperature and little rain this year, which has accelerated the growth process of cotton.

< /p >

< p > 2, reproductive growth was faster, and bud and boll growth increased rapidly.

Because of the high temperature and rapid growth of cotton after planting this year, the time for entering reproductive growth is about half a month earlier than that of last year.

< /p >

< p > 3, the overall occurrence of pests and diseases is mild.

There are slight pests and diseases in the cotton fields. The pests that we need to pay attention to are mainly cotton bollworm, Spodoptera litura, aphids and bug bugs.

< /p >

< p > 4, the overall growth is more balanced, but some three types of cotton have the risk of not being closed.

This year's disastrous weather duration is relatively short, Anxiang County affected by natural disasters such as waterlogging area is small, so cotton growth is generally more balanced.

However, some three types of seedlings, though growing faster than others, are obviously deficient in nutrition. Moreover, there are always sparse planting and big plant cultivation patterns in the area, with an average of only about 1100 plants per mu. Therefore, there are three kinds of seedlings that can not be closed.

< /p >

< p > in short, judging from the present cotton growth and the emergence of peach, the local cotton has already set up a high yield posture.

But whether we can increase production or increase production depends on the weather conditions during the picking period.

During the four months' picking season, the weather in 9 and October will become the key to cotton yield and yield increase.
