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% manganese sulfate, or 0.5% 1 packet of blue crystal code, or 600 times potassium permanganate, etc., are sprayed once in the seedling stage, early flowering stage and flower and boll 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

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.
