Sowing techniques of Cotton at the beginning of Spring
According to the variety, soil fertility and planting mode to determine the density, reasonable close planting, to achieve one sowing the whole seedling. Generally single planting spring cotton varieties, the density per mu is about 3500 plants, row spacing is 1 meter, plant spacing is 19 cm; semi-spring varieties are generally controlled at about 4500 plants per mu, row spacing, plant spacing is 15 cm; summer cotton varieties, in the plots with good fertilizer and water conditions, the density per mu is about 6500 plants; the plot of general soil fertility is about 7500 plants; and the dry and barren low-yield land is about 8000000 trees.

Recent emergency management measures for cotton
The light and heat conditions in the early part of this year are favorable for the growth of cotton, but the recent low temperature and light, overcast and rainy weather are extremely disadvantageous to the growth of cotton, and the shedding of buds and bolls increases obviously. At present, it is a critical period for the formation of cotton yield. in order to obtain high cotton yield, the following management measures should be strengthened: first, to apply topping fertilizer and foliar spraying fertilizer for cotton fields with more bolls and premature senescence, urea 5-7.5 kg per 667 square meters, foliar fertilizer can also be applied in combination with pest control. II. Rational pruning and Harmony

Jinnan District Agriculture and Forestry Bureau reminds cotton farmers to master the management techniques of cotton flowering and boll stage.
The flowering and boll period of cotton in Tianjin generally begins in early July and ends at the end of August, which lasts 55 days. According to the survey, most of the cotton fields in our district have entered the flowering and boll stage. The field management of flower and boll stage is very important, which is the most exuberant period of cotton growth and development, a period of complex contradictions between vegetative growth and reproductive growth, individuals and groups, cotton crops and environment, so it is a period to determine yield. The cotton field management in this period should pay attention to the following key aspects: 1. Increase the application of potash fertilizer.

Jinnan District Agriculture and Forestry Bureau reminds cotton farmers to master the classification and management of cotton flowering and boll stage.
Cotton from 50% cotton plant flowering to 50% cotton plant mature boll opening is called flower and boll stage. Tianjin cotton generally entered the flowering and boll period from the beginning of July to the end of August. This period is a critical period for determining cotton output. It is hoped that the majority of cotton farmers will pay attention to the situation of cotton growth in the field and adjust technical management measures at any time. According to Gao Qingming, Cotton Research Institute of Hebei Academy of Agricultural and Forestry Sciences, according to the morphological indexes such as cotton plant growth at flowering and boll stage, the cotton field was classified as overgrown, robust, general and thin. The main indicators of the four levels are as follows: ①

Cultivation Techniques of Cotton Variety Jinmian 412
Sowing period: open field direct seeding April 25 - 30, plastic film cotton April 20 - 25. Sowing must be done no later than May 5. Density: 2800 to 3200 seedlings per mu for medium fertility cotton fields and 1800 to 2000 seedlings per mu for intercropping cotton fields. Other cotton fields are appropriately increased or decreased between 2500 and 4000 plants. Medium fertility cotton field with equal row spacing: row spacing 85 cm, large row spacing 100 - 110 cm, small row spacing 60 cm. Base fertilizer application:

How to grow Cotton this year: a Survey of Cotton planting in various Cotton producing areas
Anhui-Restoration growth of Cotton acreage in order to understand the crop planting structure of farmers in Anhui Province this year, the Anhui investigation team of the National Bureau of Statistics recently selected 3220 farmers from 31 counties (districts) in the province to carry out a survey of farmers' crop intention. The results show that this year, the total sown area of crops in Anhui Province is basically stable, the area of grain crops continues to increase, the area of cash crops such as rape and medicinal materials decreases greatly, and the area of other crops is basically the same. In 2006, 3220 farmers owned 21257 mu of arable land.

Correct use of ethephon when cotton matures late this year
This year, due to the influence of low temperature, overcast and rain, cotton production in northern China has led to late sowing and emergence of spring cotton in a large area, and the budding and flowering period has been delayed by about 7 days than usual, and the cotton bolting maturity will also be delayed by more than a week. In addition, there are more overcast and rainy weather in North China from late August to early September, cotton is prone to greedy green late ripening phenomenon. Therefore, measures to promote early maturity are particularly important in the late management of cotton fields this year. Years of practice shows that the correct use of ethephon to accelerate ripening in late-maturing cotton fields is simple and easy to do and increase production.
