The period from the emergence to the emergence of cotton is called the seedling stage, and the time is 50--60 days. If seedling management is timely and scientific, cotton seedlings will grow robustly, budding early, blossoming, and tying bells early. The yield is high, quality is good, and benefits are high. If the management is not timely, the growth will be slow and the cotton seedlings will be thin and weak. The main task of seedling management is to promote vegetative growth and achieve early growth of strong seedlings. The measures for seedling management are the “early†word first, early seedlings for early warning, early seedlings for early warning, and laying the foundation for a good cotton harvest. 1, early spray auxin, promote rooting long leaves. After cotton is transferred or 1- to 2-leaf, 3000-times of 1,8% love to receive more water to promote the growth of roots and stems and leaves. For 5--6 leaves, use 0,01% Fuzi 60--80 ml/mu, add 50 kg foliar spray. Promote root, stem, leaf growth and flower bud differentiation. 2, timely support pouring wheat. During the period of flowering and filling of wheat, in the event of wind and rain, it is necessary to provide timely support to ensure sufficient light and ventilation conditions for cotton seedlings. 3, early pests. The temperature is higher in the early spring this year, and insect pests are more important than in previous years. The main pests are ground tigers, seedlings and red spiders. The use of poison baits for control of tigers is very good. The method is: 50 kg of wheat bran, 0, 5 kg of crystal trichlorfon, 0, 5 kg of vinegar, and 12-15 kg of water. Dissolve the medicine, sweet and sour water in water, and mix the wheat bran with sprayer while mixing. Four to five kilograms per mu were spread in the roots of cotton seedlings in the evening. In order to protect natural enemies, it is necessary to use stalks or hearts to control locusts and spider mites. The method is: using monocrotophos, oxidized tung fruit or early amine phosphate, 0, 1 part of sustained release agent, and 5-6 parts of water. The preparation method is to boil water and slowly add polyvinyl alcohol, until it is fully deepened. After cooling and pesticides Serve. Using a small wooden stick with cotton, apply a slow-release agent to the red-green border of the cotton seedlings. If red spiders occur, they must be reapplied twice every five to seven days to kill eggs and nymphs. 4, timely cultivator, extermination. Cotton is a thermophilic crop, with a warm temperature, rapid growth, and mild disease. The rural language said: “It was warm to the earliest days, and it was not as hard as it could be. It was a deep fruit and a deep section.†The method is “the first time shallow, the second deep, and the third time.†The cultivator is expensive in terms of “timeliness†and “deep.†5) Timely fertilizer and water management The cotton field with adequate fertilizer is generally not top-dressed, and if the base fertilizer is insufficient, it can be used as a supplement to the slasher at the time of extermination, 50 kg per mu of cake. Or high-quality agricultural and agricultural fertilizers 500 --- 1000 kilograms, urea 5 - 8 kilograms, potassium kilograms 10 kilograms, phosphate fertilizer 20 kilograms.If the weather is dry, can be combined with topdressing, timely pouring small or shallow water, prevent flooding.

Temperature: moderate temperature can avoid the chance of fruit tree encountering disease. The average temperature in ningxia is 8.4 degrees Celsius, which has an important influence on the growth, development, yield and quality of apple. The piedmont apple is thriving in such a good environment.
Humidity environment: moderate amount of rainfall provides necessary conditions for apple's growth. The annual rainfall in the central health region is 186 millimeters.

Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
