When planting cotton, you must know how to break the branches?

No one has grown cotton on our side for many years. I remember that when I was a child, I did the most things, the first thing should be herding cattle, and the second thing is picking cotton. I still remember that at that time, in order to be lazy, I used to hide the cotton I picked, and in the end, my parents found out that it was a good meal.

It's hard to look back on the past.

Cotton. Cotton is a very branching crop, but the nutrients provided by the plant are certain. If too much nutrients are wasted on the growth of branches, it will inevitably affect the yield of cotton.

By removing some of the diseased and weak branches by thrashing, the strong branches that remain are more likely to produce high-quality cotton.

Cotton. Plants use photosynthesis to produce some of the nutrients they need to grow. The cotton plant is very tall and the planting density is relatively large, and the overall light transmittance is relatively poor.

And the sticks can alleviate this problem to a certain extent. In general, cotton thrashing is to improve the quality and yield of cotton.

Cotton. When I was a child, I would be called up by my mother every morning to break cotton forks and catch insects, and the weather was cooler in the morning. Generally, the fork is divided into several stages, when the fork is broken off because it is too small to compete for nutrients, affecting the growth, the second stage, probably rise to the waist below to retain one or two, the third stage, rise to the chest position, break off the bad fork, leave more branches thick, in the head off, do not let it go to the **, so as to ensure that the nutrients are evenly absorbed into the branches, flowering and fruiting, just waiting for the fruit to ripen, naturally waiting for the joy of picking cotton harvest.

Cotton.

When the first fruit branch appears, the first fruit branch and the lower leaf branch are removed in time, and the main stem leaves are retained to provide organic nutrients to the root system, which is called defoliating branches or grouts. Removing leaves and branches is one of the means to control the growth of cotton and seize high yields, and the cotton plants in the weak seedlings and lack of seedlings can not go to the leaf branches, and wait for them to elongate before beating the edges. Leaf removal is carried out at the beginning of budding.

The pruning at the flowering stage is mainly to promote the reproductive growth of plants, improve the fruiting rate and the quality of cotton bolls. The first thing to do is to do topping, which is usually done around July every year, when the fruit branches grow to about 11 is the best time to do topping. It is best to remove the topping at one time, and it is not advisable to do it on a rainy day, otherwise it will cause a great obstacle to the wound healing of the plant.

After topping, it is necessary to spray Zhuang Su appropriately to promote growth, and then pay attention to the work of beating the heart. Finally, wipe the buds and prune, remove some useless cotton bolls, and if there are too many buds, they should also be removed in time to enhance the photosynthesis of cotton.

When planting, the excess branches and leaves should be removed, and the branches can be broken at the position of the cotton tree 1 3, and the top branches should be broken when flowering, so as to promote the growth of the lower cotton.

Pruning at the cotton bud stage is mainly to remove the leaves and branches. The growth of leaves and branches is strong, and the consumption of nutrients is large, which aggravates the contradiction between vegetative growth and reproductive growth. When the fruit branch and leaf branch are identified, the leaf branch below the first fruit branch should be removed, but the large leaf at the bottom of the main stem should be retained to maintain a large leaf area and enhance the photosynthetic capacity.

If you encounter a place where there is a lack of seedlings and broken ridges or the bottom edge of the ground, you can also leave it appropriately.

One or two leaf branches to make the most of the space. The second is the smearing buds. Hair buds grow fast, consume a lot of nutrients, and affect the development of bud bells, so it is necessary to wipe them off in time.

The application of cotton pruning technology has been practiced for a long time in China, and the pruning technology has to remove leaf branches, hit the top heart, hit the edge heart, wipe the buds, remove the invalid buds, cut empty branches, beat the old leaves, etc. There are about 10 labors per mu. Many scientific and technological personnel have long held different opinions on the yield increase effect and economic benefits of cotton pruning, and a large number of pruning experiments have been carried out in various cotton areas.

Due to the different climatic conditions, varieties and management measures in different places, the experimental results are very inconsistent, and the effects of pruning on yield are some showing increased yield and some showing reduced yield. However, after pruning, the boll rot decreased, which promoted early maturity, increased pre-frost flower yield, and high fiber quality. Therefore, most people believe that cotton pruning is inevitable, but it does not have to be too delicate, and it should be appropriately simplified according to local climate, varieties and other conditions.

In general, cotton fields should be topped and foliage removed; Dry and thin cotton, only topping is fine; In addition to topping and removing leaves, other pruning measures should be taken, either to control fertilizer and water, or to use chemical pesticides. In order to promote early maturity, reduce post-frost flowers, reduce rotten boll and improve fiber quality, necessary pruning measures should be taken. Experiments have proved that the cultivation technology of proper control of fertilizer and water and chemical control can better control the individual growth of cotton and the development of the population.

a. The purpose of timely pruning and pruning of cotton is to allow the side buds to develop into branches, a wrong;

b. Timely pruning and pruning of cotton can reduce the concentration of auxin pants in the side buds, and can not make the fruit branches get enough nutrients, b is wrong;

d. The purpose of timely pruning and pruning of cotton is to remove the apical buds and reduce the concentration of the side buds, so as to remove the apical dominance and let the side buds develop into branches

Therefore, d
