First, the nutritional characteristics of cotton and the law of fertilizer requirements. (1) Emergence to the present bud. The nitrogen content of cotton during its lifetime is the highest in this period. (2) Now bud to flowering period. At this time, if the nitrogen supply is too much, it will often cause the cotton plant to grow long and increase the bud bell to fall off, so it is necessary to avoid applying too much nitrogen fertilizer. The addition of potassium fertilizer can increase the potassium content in stems and leaves, especially the increase of potassium content in stems and leaves. (3) The flowering period to the beginning of the flocculation period. The levels of phosphorus and potassium in the reproductive organs increase rapidly. Insufficient supply of phosphorus and potassium will affect the intake of nitrogen.
Second, cotton fertilization technology.
Manure, compost and nitrogen fertilizer. They are common farmyard manure in cotton fields. Cotton fields generally use 30-45 tons per hectare (1 hectare for about 15 acres) and high-yield cotton fields 45-75 tons per hectare. In the general cotton field, in the case of applying a total nitrogen of 112.5-150 kg per hectare, 37.5 kg of pure nitrogen is used as the base fertilizer, and the soil is applied to the soil before the ploughing together with the farmyard manure (the rest is topdressed in the flowering and bolling period), and good results can be obtained. . In the middle and upper soil, the loamy soil has strong ability to maintain fertilizer and fertilizer. The nitrogen fertilizer is applied twice, and the base fertilizer is applied for about 45%. The other time is about 55% in the flowering and bolling period. The cotton field with high soil fertility and strong fertility ability can also use the appropriate amount of nitrogen fertilizer as the base fertilizer; for the cotton field with poor soil fertility, sandy soil and poor fertilizer retention capacity, the nitrogen fertilizer can be applied in three times, ie 30% of the base fertilizer, bud The topdressing fertilizer is 20%, and the flowering and seasoning is 50%.
Potassium fertilizer has a good effect on the application of base fertilizer and top dressing, and the application of base fertilizer alone has a good effect. Potassium fertilizer should be applied according to the condition of soil fertility. On the basis of nitrogen and phosphorus application, potassium chloride or potassium sulfate should be applied 135-150 kg per hectare in medium-weight cotton field, and potassium chloride or potassium sulfate should be applied per hectare in medium and low-grade cotton field. About 225 kg.
Boron fertilizer can be used as base fertilizer, seed fertilizer and top dressing. The cotton field with severe boron deficiency (effective boron in soil is less than 0.2 mg/kg) is applied to the seeding ditch or transplanting ditch and acupoint in the seedling ditch with 3.75-7.5 kg per hectare. Miao Lei period: cotton seedlings and buds have little demand for nutrients. Generally, cotton fields can be used without top dressing under the conditions of applying base fertilizer. However, in the case of cotton and wheat double-cropping, since the cotton seedlings are affected by wheat fertilizer during the symbiotic period of cotton and wheat, the growth is weak, and appropriate topdressing is needed to promote growth. After the wheat is harvested, it is necessary to cultivate the cockroach as soon as possible and topdress the shallow water. Generally, the amount of fertilizer used is about 52.5-75 kg per hectare or 2250-3750 kg of decomposed manure.
Phosphate fertilizer is mainly used as base fertilizer, which can meet the needs of cotton during the whole growth period, so cotton is generally no longer applied with phosphate fertilizer.
