Key points of Cotton cultivation at Bud stage
The climate of cotton bud stage in 2008 is extremely disadvantageous to the growth of cotton, with low temperature and high humidity, resulting in cotton growth lagging behind 3-5 days compared with previous years, cotton disease is serious, the overall growth is weak. How to strengthen the management of bud stage and build a high-yield shelf, we should pay attention to the following points in management: steady application of bud fertilizer: scientific fertilization according to soil conditions, application of base fertilizer and cotton growth. Cotton fields dominated by phosphorus and potassium fertilizer, with high soil fertility, sufficient bottom fertilizer and prosperous growth, are not suitable for topdressing nitrogen fertilizer, which can be properly topdressing 25kg / mu cake fertilizer.

6 points must be caught at the bud stage of cotton
Proper watering due to less rainfall and hot weather in northern China in mid-late June, it should be properly watered, but not too much, so as not to cause cotton to flourish and cause buds to fall off. Ploughing should be done in time after watering or heavy rain to promote the root system of the plant. Topdressing to promote weakness is generally applied every 667 square meters of urea 5kg, potassium chloride 15kg 20kg, zinc sulfate 1kg, borax 1kg, in order to promote the plant to build a high yield shelf. When applying fertilizer, the fertilizer should be trenched and applied deeply about 15 cm away from the plant. Topdressing at bud stage should take care of the weak.

Field Management Technology of Cotton at Bud stage
In order to set up a high-yield shelf of cotton, according to the growth characteristics of cotton at bud stage, in view of the production situation that there are more late-planted cotton and unbalanced growth this year, specially put forward the following technical measures of field management: first, make clear the guiding ideology and main target guiding ideology: seize the opportunity to strengthen science and technology, reduce humidity and increase temperature to promote rooting, improve nutrition, adjust plant type, and promote fitness to seek balance. Main target: grow steadily and grow steadily, strong plants increase buds. Second, highlight the key points of field management and strictly control the key technologies. 1. Improve the finishing work of the upper compartment of deep ploughing and high ploughing, and as an important part of the current field management.

Strengthen the culture tube at the bud stage of cotton
After transplanting cotton this year, there was continuous drought and little rain, the temperature was unstable, and the squatting time was long, which seriously affected the growth of cotton plants. in addition, aphids and red spiders occurred in a large number and seriously harmed, resulting in the emergence of secondary squatting seedlings, a small number of cotton seedlings with red stems to the top, and true leaves dry and shedding. Recently, Rain Water alleviated the drought, and the seedling condition began to transform. The interplanting of cotton had 7 or 9 true leaves and began to bud, and the cotton also began to grow after wheat (oil), but the overall seedling condition was not as good as in previous years. The bud stage is the most important period in cotton life, so we should focus on the following measures.

Key points of Cotton Bud stage Management
Cotton bud stage is an important turning point in cotton life. In this period, vegetative growth and reproductive growth go hand in hand, mainly vegetative growth. On the basis of strong seedlings and early development, production management should take reasonable promotion and control measures to achieve stable cotton growth and build a high-yield shelf. The main technical points are as follows: 1. Continue to do a good job of ditching and drainage to prevent bright and dark waterlogging. 2. Ploughing and cultivating soil to promote the development of cotton root system. 3. Pruning in time. The vegetative growth of hybrid cotton is exuberant, and there are more leaf branches and buds. Depending on the field planting density, it is appropriate to leave 1-2 leaf branches per plant.

The word "steady" should be the first in the management of cotton bud stage.
At present, cotton has entered the bud stage one after another. As the saying goes, "if cotton wants high yield, the stable growth of bud stage is the foundation." According to the investigation in the countryside and the problems encountered in the technical guidance, combined with the climate characteristics and the growth trend of cotton this year, the author thinks that the management of bud stage should be carried out around the word "stable" on the basis of "simplification, labor saving, high yield and high efficiency". And measures should be flexible and suitable for seedlings. The specific points are as follows: first, with the promotion of plastic film cotton and the use of herbicides, the number of intertillage is significantly reduced, but the necessary intertillage is still necessary.

Technical questions and answers on Cotton Bud stage Management
1. What is the bud period? Answer: when buckwheat grain size triangular buds appear on the first fruit branch of cotton plant, it is called budding. 50% of cotton plants in the whole field are called budding stage; when 50% of cotton plant fourth fruit branch is budding, it is called budding stage. The bud period is generally between 25 and 30 days, and "28 flowers with buds" (days) refers to the bud stage. The cultivation mode and temperature are different, the bud stage is slightly different, and the bud stage is generally from early June to early July in the north of the Yellow River. 2. Why should we pay attention to the management of bud period? A: this stage is

Emergency measures for Cotton Bud and Boll shedding
When cotton grows in high temperature and rainy climate, a large number of buds and bolls will fall off, resulting in plant height, size and emptiness, resulting in a large reduction in yield. According to the causes of different shedding, corresponding emergency remedial measures can be taken. For cotton fields that have been dry for a long time without rain and can not be watered, the leaves of cotton plants are thin and small, the leaves are light green and yellow, the chaff of buds is small, heavy rain falls heavily, light rain falls less, and no rain falls gradually. Remedial measures: 200 grams of multi-element boron fertilizer per mu plus 20 ml of Fengchengning, evenly sprayed with 50 to 60 kg of water, interval

The management of cotton bud and boll period should be strengthened.
Bud stage management: after cotton enters the bud stage, all localities should adopt measures according to seedling system and classified management. In the first type of cotton field, the vegetative growth of cotton plant is exuberant, so it is necessary to regulate and control reasonably, shape the ideal plant type, promote the early boll setting, multi-boll setting and big boll setting of cotton plant; the second type of cotton field should promote the combination of control and control to promote the cotton plant to build a high yield shelf early; the third type of cotton field should develop late and grow weakly. The method of promoting both water and fertilizer should be adopted to promote the early emergence of cotton seedlings. Focus on the following aspects of work: 1, pay attention to the "four robbers" management. After interplanting in the wheat field and cotton field, the wheat should be watered and killed in time.

Remedial measures for cotton waterlogging crops
If the whole cotton plant is submerged for more than 3 days or soaked for more than 7 days, the root system will rot and turn yellow, and the top leaves will die. This kind of cotton seedlings have little possibility of survival and need to be replanted. 2-3 days after discharge, those with more than 500 surviving cotton plants per mu should be kept and intercropped with soybean, corn, sesame and other crops; those with less than 500 surviving cotton plants per mu should be replanted and changed as soon as possible. After the disaster, the root system of cotton was damaged, the main root and lateral root turned yellow, and the root tip showed water stains. "grabbing and drainage, early soil loosening, heavy fertilization, disease and insect control, late topping and diligent pruning" should be adopted.
