Water floating Seedling raising technique of Cotton
1. Seedbed preparation: each seedbed (per mu) needs to be excavated by 1. 1-1. 2 meters, 20 centimeters deep, 2 long. 2 meters of field, flat bottom tamped for four weeks. 2. Film laying: choose 0. 06-0. The 1mm thick film is laid on the excavated seedbed, close to the sides of the seedbed, and check for water leakage and air bubbles. 3. The substrate plate: the matrix is sprayed into a ball by hand, and there is no running water between the fingers. If it falls to the ground and spreads naturally, it can be loaded into the seedling tray, so that the matrix shakes to 1-1 away from the disk. Five centimeters. 4. Match

The Seedling technique of Cotton floating in Water
"Cotton floating Seedling Technology" is a new cotton planting technology developed by agricultural experts in Hunan Province. this technology uses porous polyethylene foam seedling tray as carrier and mixed substrate as support. The seedling tray containing cotton seeds is put into the nutrient liquid water nursery bed for cultivation, which has significant seed saving, labor saving, yield increasing and synergism, and the seed consumption is more than 40% less than that of conventional nutrition bowl seedling transplanting cotton. The labor consumption of raising seedlings and transplanting per mu is reduced by about 10. Cotton seedlings have developed root system, low degree of Lignification, soft and elastic, not easy to break and strong vitality.

Boron Application Technology of Cotton
In recent years, the statistics of boron fertilizer experiments on cotton showed that the application of boron fertilizer could increase cotton yield in both boron deficient soil (soil available boron less than 0.5 mg / kg) and potential boron deficient soil (soil available boron less than 0.8 mg / kg). 1. Base fertilizer cotton was applied before sowing or nutrition (rice) before transplanting combined with soil preparation. About 0.5 kg of borax per mu can be mixed with nitrogen, phosphorus, potassium and other fertilizers and then applied together, or mixed with fine dry soil. 2. Grow fertilizer in cotton

Attention should be paid to the management of cotton bud stage
At present, most of the cotton in our province has entered the bud stage. in view of the current situation of high temperature and heat, drought and little rain in most areas, the following management technical suggestions are put forward for the majority of cotton farmers' reference. First, watering and fertilizing. It is necessary to properly water and apply a small amount of nitrogen fertilizer to promote seedlings. For the cotton fields with poor soil fertility, insufficient or less base fertilizer and weak cotton growth, the combination of watering can top up 5 kg of urea per mu. Can also increase the application of phosphate fertilizer, potash fertilizer, general mu application of diammonium, potassium sulfate or potassium chloride each 5 kg. Second, active chemical control. Active chemical control by spraying propofol before watering

Key Technology and Economic benefit of Deep-buried drip Irrigation for Cotton
Cotton "deep-buried" drip irrigation technology is another new and efficient water use technology after cotton hose micro-hole irrigation technology under plastic film. This technology can make efficient use of fertilizer and water, and the effect of increasing production is obvious. 1. Key technologies 1. The irrigation time is the budding stage of cotton, and the cotton area in northern Xinjiang is generally from June 7 to 10. The irrigation is carried out according to a rotation irrigation cycle of 3 days. If it is rainy in autumn, it can be irrigated according to a cycle of 5 days. Irrigation amount: 8 cubic meters per 667 square meters at budding stage and 10 cubic meters at full flowering stage

Cultivation and Management techniques of Cotton hose drip Irrigation
With the increase of crop area, the shortage of water resources and the increase of cotton cost in Jimusar County, the comparative benefit of cotton decreased year by year. For this reason, we introduce and popularize the cotton under plastic film atmospheric pressure (hose) drip irrigation cultivation technology. 1. Main indicators 1. The output is 667 square meters, 100-130 kg lint. Yield components: the number of harvested plants per square meter is 1.3-15000, the number of bolls per plant is 5-6, the weight of single boll is 5 grams, and the lint percentage is 33%. 35%. two。 Fertilizer and water

Symptoms and remedial measures of Manganese deficiency in Cotton
The young leaves first appeared dark green and light green stripes between the veins, and the middle part of the leaf was more obvious than the tip of the leaf. The leaf tip is light green at first, and some small withered spots appear in the white stripes at the same time, then connect into strips of dry tissue and make the leaves split longitudinally. Symptoms easily occur in the upper part of the plant and young leaves from the early budding stage to flowering stage. Inducing conditions: pH7, sandy, low content of organic matter in the plots with low available manganese content, too much Rain Water is easy to leaching. Fertilization method: bottom application of six high base fertilizer king is the best, or 0.2%

Integrated Technique of Cotton Pre-weight Simplified Cultivation
The integrated technology of simplified cotton cultivation is a new technology developed to solve the problems of high labor intensity, many management links and high production cost in cotton production. The so-called pre-emphasis mode means that most of the cotton management work is placed in the early stage of growth, and the possible problems are placed in the early stage of prevention, changing the past three seeds and seven branches into seven seeds and three branches; the so-called simplified cultivation means removing unnecessary links in the traditional cotton management practices and simplifying the operation procedures; the so-called integrated technology is to integrate the operation technology into a set of technical systems and standardize them.

Key points of cotton management in July
July is the month of the fastest growth and the largest growth of cotton, and it is also the month of drastic weather changes, many disasters and serious diseases and insect pests. Most cotton fields enter the flowering stage in early July, and by the end of July, 90% of the vegetative and reproductive organs of cotton plants have grown; the root network of cotton was also completed in July, forming a peak of absorption of mineral nutrients and water. The summer day entered in the middle of July, which is the fastest and largest month for cotton transformation. From the above aspects, the cotton management in July has the nature of a decisive battle. (1) to dig trenches to cultivate soil. It is good for watering and

How to manage cotton after topping in July
Heat or high temperature and humidity is one of the most harmful factors in the breeding industry, which will lead to the occurrence of heat stress syndrome in livestock and poultry. Heat stress suppresses the immune function of the body, reduces the concentration of immunoglobulin in blood and the number of lymphocytes in blood, resulting in the decrease of phagocytosis of macrophages in the body and infectious diseases of livestock and poultry. Therefore, heat stress will make livestock and poultry prone to all diseases. As the higher the production performance of modern excellent livestock and poultry breeds, the worse the ability to resist heat stress, serious heat stress often causes the livestock and poultry with high performance to die first, resulting in serious economic losses. Improve the performance of livestock and poultry
