Resolutely relax the small row spacing of cotton-- the second suggestion of consultation service in rural areas in 2008
Before sowing, the author visited some cotton areas in Hebei, Shandong, Shanxi and Shaanxi and found that the small row spacing of cotton in most areas was too narrow, which seriously hindered the normal growth and development of cotton plants, so planting reform must be carried out from the population structure. The top priority is to relax the small line spacing. In order to cover cotton with plastic film, cotton farmers mostly use large and small rows to sow seeds, one sowing two rows. In most areas, 90 cm wide plastic film is used, and the width of small line spacing is about 45 cm. This is not conducive to the normal elongation of fruit branches and flowering bolls, but also the formation of unbalanced growth on both sides of cotton roots. Very

Strengthening the classified Management of Cotton after Rain
In view of the current complex situation of cotton seedlings, in order to promote balanced growth and enhance stamina, corresponding measures should be taken to classify and guide, strengthen management, and strive to resist disasters and win a bumper harvest. First, seize the season and fatten up as soon as possible. It is the main contradiction of cotton management to apply fertilizer quickly and quickly, but it should be classified and implemented. It is necessary to apply 15 kg of compound fertilizer, 10 kg of urea and 15 kg of potash fertilizer per mu for cotton that has already blossomed and set bolls, and 2000-2500 kg of mature organic fertilizer per mu for cotton entering full budding stage, or bio-organic.

Strengthening the Management Technology of Cotton in the Middle and late stage in Hebei Province
At present, spring sowing cotton in Hebei Province has entered the flower and boll stage from south to north one after another. due to the good sowing foundation, timely field management, more precipitation in the early stage, sufficient light, the cotton plant type in Hebei Province is neat, the growth is steady, and the harm of diseases and insect pests is lighter. The growth in the field is generally better than in previous years. Recently, a group of provincial cotton experts and consultants conducted a field investigation of cotton in 21 counties (cities) in Handan, Xingtai, Hengshui and Cangzhou. According to the investigation, the average plant height is 60cm to 70cm, the number of leaves on the main stem is 1517cm, and the number of fruit branches is 812cm. The growth process is basically normal.

What is the "happy" cultivation of cotton?
The happy cultivation of cotton is to coordinate the relationship between cotton and climate, aboveground and underground, vegetative growth and reproductive growth through artificial measures to actively and predictably regulate the individual development of cotton plants and cultivate high light efficiency plant types under certain conditions. make the best boll setting space in the best boll setting period, so as to achieve the goal of high yield and high quality. SGK321 cotton is a bivalent transgenic insect-resistant cotton, which is obtained by biological breeding and should be a conventional insect-resistant cotton.

Control of cotton aphid
Control of cotton aphid 1. Rotate the use of potions. Acetamiprid, imidacloprid, chlorpyrifos and other conventional pesticides in the field are used alternately to reduce the possibility of drug resistance of aphids. Once aphids develop resistance to a certain chemical, even if the times of drug use and concentration are increased, the ideal control effect will not be achieved. two。 Spray the occurrence site thoroughly. Now the cotton is in full bloom, the plant is tall, we must be careful when spraying, focus on spraying the back of the middle and lower leaves of cotton, strictly prevent missed hit, missed spray, practical

Cotton harvest should be managed well in July and August
1. The importance of the decisive battle in July and August Cotton boll period is the longest stage in cotton growth period, and it is the most abundant period of natural resources such as light, heat and water, which is very conducive to cotton growth and development. However, there were disadvantages in this period. Not only were natural disasters such as wind, hail, drought and waterlogging frequent, but diseases and insect pests were seriously harmed. There was a saying in the agricultural proverb that "cotton is grass, good can go bad, bad can go good". Therefore, this period is the key period to seize the cotton harvest, especially this year, in the cotton growth process delayed 7 to 10 days than in previous years, seedling situation
