High-yield cotton nutrients

The invention relates to a high yielding cotton nutriment for cotton planting. The nutriment is prepared by raw materials of urea, monopotassium phosphate, calcium nitrate, magnesium sulfate, boric acid, manganous sulfate, ferrous sulfate and copper sulphate according to growth rule of cotton and nutrition characteristics. The nutriment can be used as base fertilizer and after fertilizer and can be sprayed to leaves; owing to coordinating balance of various medium and trace elements, the nutritive elements are comprehensive and matched reasonably, so that poison caused by excess elements and lack of elements can be prevented, various plant diseases and insect pests can be prevented, cold-resistant and drought-resistant capability of cotton can be enhanced and growth of cotton can be promoted; therefore, the cotton has high yield, early maturity and good quality. Meanwhile, the invention has the advantages that use amount is less, cost is low, preparation is simple, use method is flexible, and the nutriment can meet needs at various growing periods, can effectively prevent hardening and barrenness-caused declining of soil and is favorable for virtuous circle of water and soil environment.
