Xinjiang friends, cotton planting methods and which use to the farm equipment is what ah?

Agricultural machinery to be used, arable land is generally used bulldozers with large plows and harrows, seeders, weeders, medicine machines (small and large), harvester (cut cotton stalks), cotton picker (basically do not use, yet to be popularized)

Cotton planting:

Cotton absorption of nutrients increases with its yield, nitrogen, phosphorus and potassium absorption ratio is about 1.0:0.3:1.0. The absorption ratio is about 1.0:0.3:1.0. The dosage ratio of nitrogen, phosphorus and potassium fertilizers is about 1:0.65:1.0. 40% of the nitrogen fertilizers are generally used as basal fertilizers, 40% as bollworm fertilizers, and 20% in the beginning of the peaches are applied. Phosphorus fertilizer to do the whole layer of fertilizer is good, potash fertilizer to base fertilizer, fertilizer half of the effect of half application, cotton has a good response to zinc and boron, should pay attention to zinc fertilizer and boron fertilizer application.

I, cotton nutritional characteristics and fertilizer law. (1) seedling to bud. Cotton lifetime nitrogen level is the highest in this period. (2) bud to flowering. At this time, if the nitrogen supply is too much, often cause the cotton plant to grow, increase the bud boll shedding, so we should avoid applying too much nitrogen fertilizer. Increase the application of potash fertilizer, can increase the amount of potassium in the stem and leaves, the increase in the amount of potassium in the stem and leaves is particularly obvious. (3) Flowering period to the beginning of flocculation. The content of phosphorus and potassium in reproductive organs increases rapidly. Insufficient supply of phosphorus and potassium will affect the uptake of nitrogen.

Two, cotton fertilizer technology.

Stable manure, compost and nitrogen fertilizer. They are commonly used in cotton farmyard fertilizer, cotton fields generally 30-45 tons per hectare (1 hectare is about 15 acres) with 30-45 tons of base fertilizer, high-yield cotton fields 45-75 tons per hectare. General cotton fields, in the case of 112.5-150 kg of total nitrogen per hectare, with 37.5 kg of pure nitrogen as a base fertilizer, together with farmyard manure applied to the soil before ploughing (the rest of the bolling period as a follow-up fertilizer), you can get good results. Medium and high fertility loamy soil, fertilizer retention, fertilizer supply capacity is strong, nitrogen fertilizer is good in two applications, one as a base fertilizer about 45%, another time in the flowering bells about 55% is appropriate. Higher fertility, fertilizer capacity of the cotton field can also be appropriate amount of nitrogen fertilizer as a base fertilizer; poor soil fertility, sandy texture, poor fertility cotton, nitrogen fertilizer can be divided into three applications, that is, 30% of the base fertilizer, 20% of fertilizer during the bud stage, fertilizer during the bolling period, 50% of the bolling period.

Potassium fertilizer to base fertilizer, fertilizer half of the application of the effect is better, single base fertilizer application also has good results. Potassium fertilizer should be applied according to the ground conditions, in the application of nitrogen, phosphorus, on the basis of the general medium strength cotton fields per hectare with potassium chloride or potassium sulfate 135-150 kg, the lower strength cotton fields per hectare with potassium chloride or potassium sulfate 225 kg.

Boron fertilizer can be used as base fertilizer, seed fertilizer and follow-up fertilizer. Severe boron deficiency in cotton fields (soil effective boron less than 0.2 mg / kg) 3.75-7.5 kg per hectare in the sowing ditch or transplanting ditch, hole as seed fertilizer is very effective. Seedling bud period: cotton seedling, bud period of nutrient demand is not large, the general cotton field in the conditions of adequate fertilizer, you can not apply fertilizer. However, the case of cotton and wheat two maturity sets, because the cotton seedlings in cotton and wheat **** during the birth of wheat fertilizer absorption, growth is weaker, the need for appropriate fertilizer to promote growth. In wheat harvested as soon as possible after plowing stubble, fertilizer shallow water, general seedling fertilizer dosage per hectare of about 52.5-75 kg of urea or rotted human waste 2250-3750 kg.

Phosphorus fertilizer is mainly used as a base fertilizer, you can meet the needs of cotton throughout the life of the cotton, so cotton is generally no longer applied phosphate fertilizer

I hope my answer you can be satisfied!
