A special fertilizer for peanuts for single-grain precision sowing and preparation method thereof

Abstract

The invention provides special fertilizer for single-seed precision sowing of peanuts. The special fertilizer is prepared from following raw materials: 150 parts of biochar, 300 parts of resin-coated urea, 50 parts of urea, 360 parts of calcium superphosphate, 80 parts of potassium sulphate, 300 parts of livestock manure, 7 parts of zinc sulfate, 10 parts of ammonium molybdate, 8 parts of magnesium sulfate, 12 parts of borax, 80 parts of humic acid and 3.2 parts of an additive NAM. The special fertilizer can improve soil, increase the content of carbon-based organic matters in the soil, rapidly transform the soil structure, balance salt and water and create a soil environment beneficial to healthy growth of plants through rapid ripening, so that the soil fertility is improved, the requirements for growth and development of single-seed precision sown peanuts in each growth period are met, early and rapid germination in an early stage is promoted, fertilizer shortage in a late stage is avoided, the growth periods are prolonged, late-stage substance accumulation and transfer to pods are promoted, the pods are full, and the yield and the quality are improved remarkably.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a special fertilizer for peanuts under the condition of single seed precision sowing and a preparation method thereof. Background technique [0002] For a long time, people have traditionally been used to sowing peanuts in double seeds per hole, sowing about 150,000 holes per hectare, and generally need 300-375kg / hm2 for a large amount of peanuts 2 , small peanuts generally need 225 ~ 260kg / hm 2 . The peanuts used for seeding in the country are about 1500kt every year, accounting for about 10% of the total output of the country. Not only the amount of seeds used is large and the cost is high, but also under the condition of high density, the contradiction between the group and the individual is prominent, the quality of the group decreases, and the output decreases . [0003] Single-seed sowing of peanuts was proposed by Wang Lanxin as early as the 1930s, mainly to reduce ...

AI Technical Summary

Problems solved by technology

However, in terms of production, growers still use traditional fertilizer types and fertilization methods, resulting in low fertilizer utilization rates and unable to fully meet the growth and development needs of precision-sowed peanuts

[0004] At present, the traditional fertilization in peanut production is mostly quick-acting fertilizer, which has a short fertilizer effect period and cannot meet the fertilizer requirements of precision sowing peanuts. Premature and rapid growth in the early stage will not meet the requirements of strong seedlings, which will easily cause malnutrition, and premature aging in the later stage, which will affect the increase in production and efficiency
