Simplified cultivation measures for High yield of Cotton
In the process of cotton cultivation, cotton farmers often consult: why is the shedding of buds and bolls serious? Why are there so many spades? In addition to "complaining about the bad weather" and "complaining too much about Rain Water", cotton farmers should also think that the excessive density of cotton fields is the "culprit". In the past, cotton farmers were "one? It is common to keep 5000-6000 seedlings per mu of Yuanyi. At present, cotton fields with a density of 3000 to 4000 plants per mu can still be found everywhere, and "excessive density" is a common problem of most cotton farmers. As a result, a single plant of cotton is produced.

Key points of High-yield cultivation techniques of Cotton
According to the investigation and analysis of cotton production in recent years, a set of cultivation and management models suitable for the central and southern cotton areas of Pucheng were summarized, that is, April seedlings, May buds, June flowers, pickled flowers at the end of July, skillful tube August, tender after September, autumn peach cover, stubble at the end of October. Through the demonstration application of 5256 mu at 6 points in a row for three years (06, 07, 08), a gratifying harvest of 346.1 kg per unit yield of seed cotton was obtained, and the output value per mu reached 1827.40 yuan (according to the 3-year average price of 5.28 yuan / kg).

High-yield cultivation techniques of Cotton
First, select suitable cotton varieties 1. The plant height of Liaomian 10 is about 70 cm, and the leaf color is thick green and fat. There are 8.43 bolls per plant, with round bolls and lacking tips. The growth period of bare land cultivation is 146 days, film mulching is 137 days, which is suitable for film mulching cultivation, and the pre-frost flowering rate is 83%. Strong growth potential, easy to protect seedlings, not premature senescence, good boll setting, uniform cotton boll size and concentrated opening. The average boll weight is 4.67 grams, the lint percentage is 35.72%, and the fiber length is more than 29 mm. Strong resistance to Fusarium wilt

There are similarities and differences in fertilization among different cotton varieties.
Recently, when the author went to the cotton producing areas of Tianmen, Hanchuan, Jingshan, Jianli and other counties and cities of Huarong, Anxiang and Nanxian of Hunan Province, many farmers asked about the technical problems of cotton fertilization. They often regard fertilization as one of the important means to increase production, so they are very concerned about fertilization technology. The experiences and lessons of cotton fertilization for many years tell us that the common experiences of increasing cotton yield are as follows: sufficient base fertilizer, rapid application of seedling fertilizer, stable application of bud fertilizer, heavy application of flower and boll fertilizer, and general application of peach fertilizer. However, there are differences in the application of fertilizer among different cotton varieties.

Skillful fertilization of cotton
Fertilizer is the material basis for high yield of cotton, and fertilization on demand is the highest principle of fertilization for cotton. Soil testing and fertilization should be carried out where possible, and what fertilizer and amount of fertilizer should be determined according to the content of soil available nutrients and the need for high yield of cotton. For most cotton fields in the north, the amount of potassium fertilizer should be increased and the amount of phosphorus fertilizer should be reduced, while nitrogen fertilizer should be mainly used for topdressing, or the formula fertilizer of "high potassium, low phosphorus and medium nitrogen" should be applied. If the same amount of nitrogen, phosphorus and potassium compound fertilizer is used, the amount of compound fertilizer should not exceed 25 kg per mu, and the amount of potash fertilizer should be increased by 12.5 kg.

Technology of balanced fertilization for Cotton
Cotton fertilization principle 1. Cotton production should be sustainable with the combined application of organic fertilizer and inorganic fertilizer. Organic fertilizer has the characteristics of complete nutrients and stable long-term fertilizer effect, which can not be replaced by inorganic fertilizer. Even under the condition of sufficient supply of inorganic fertilizers, the role of organic fertilizers should not be ignored. only the combined application of organic fertilizers can achieve high and stable yield, especially when the price of chemical fertilizers is high, more attention should be paid to the application of organic fertilizers. 2. the balanced application of large amounts of elements and trace elements refers to the balanced application of large amounts of elements.

Technical essentials of cotton formula fertilization
Cotton growth is characterized by unlimited growth, regeneration ability, plant shape controllability, large fertilizer requirements. Generally speaking, adequate fertilizer is the basis for high yield and quality of cotton. Adequate phosphorus fertilizer can promote cotton plant robust growth, increase boll weight, early maturity. Potassium fertilizer is a catalyst for many enzymes in plants, which can promote photosynthesis and cellulose synthesis. Cotton fertilization technology is "nitrogen, potassium, phosphorus, boron spray" eight words formula fertilization method. Specifically, the following five technical measures should be taken. 1. Pay attention to the application of farm manure

Technology of Formula fertilization for Cotton
At present, it is the critical period of cotton preparation for cultivation and fertilization, in order to do well the formula fertilization of cotton and lay the foundation for high quality and high yield. The fertilization technology of cotton is now provided to the majority of cotton farmers for reference: first, attach importance to the application of farm manure: farm manure can improve soil, improve soil fertility, and contain various nutrient elements needed by crops for crop growth. it is nutritious and rich in organic matter. it plays a significant role in improving soil and improving the utilization rate of chemical fertilizer. Second, increase the application of phosphate fertilizer: the movement of phosphorus in the soil is small, and the dissolution and release is slow.

Seven key points of Scientific fertilization for Cotton
1. Give priority to organic fertilizer and apply sufficient base fertilizer. During soil preparation, the soil was disinfected by spraying disinfectant and 800 times solution of new high-fat film in time, and applying sufficient base fertilizer, applying 2000-3000 kg farm manure per mu to improve the ability of root system to absorb fertilizer, activate the soil, prevent consolidation and maintain the ecological balance of the rhizosphere. two。 Reduce the application of diammonium phosphate. Nitrogen, phosphorus and potassium ternary compound fertilizer should be used, or 40 kilograms of three 15 nitrogen, phosphorus and potassium compound fertilizer can be selected as base fertilizer. Cooperate with spraying when using compound fertilizer

Fertilizer Application in Cotton Flowering and Boll Stage
Name: Cotton flowering and boll stage fertilization pay attention to classification: planting technology/plant physiology principles and cultivation techniques Scope of application: unlimited Details: Cotton flowering and boll stage is the key period for cotton to gradually shift from vegetative growth to reproductive growth, and it is also the period when cotton needs the most fertilizer. For cotton at the peak of flowering, because vegetative growth is still parallel to reproductive growth, partial application of nitrogen fertilizer at this time will lead to vigorous growth and crazy growth of cotton, not only aggravate bud and boll shedding, but also cause premature senescence. Therefore, part of cotton in full bloom should be
