Compound fertilizer for improving yield of lotus roots

Abstract

The invention discloses compound fertilizer for improving the yield of lotus roots. The compound fertilizer is prepared from the following raw materials in parts by weight: 30 to 60 parts of compound urea, 22 to 30 parts of sodium nitrate, 15 to 25 parts of potassium polyphosphate, 10 to 20 parts of monobasic potassium phosphate, 5 to 10 parts of starch, 15 to 25 parts of sesame cake, 10 to 20 parts of radish leaf, 15 to 25 parts of earthworm excrement, 10 to 18 parts of shell powder, 15 to 25 parts of molasses powder, 7 to 12 parts of active carbon, 5 to 10 parts of talcum powder, 5 to 10 parts of zeolite powder, 3 to 5 parts of sepiolite powder, 1 to 4 parts of manganese sulfate, 2 to 4 parts of ferrous sulfate and 3 to 5 parts of calcium silicate. According to the compound fertilizer disclosed by the invention, various nutrient elements needed by the growth of the lotus roots are reasonably compounded and fertilizer-retention and slow release performances are excellent; healthy growth of the lotus roots can be remarkably promoted, so that the yield is improved, the quality is improved and the economic benefits are increased; meanwhile, the adding amount of the fertilizer can also be reduced and environment pollution risks caused by the fact that the fertilizer is not properly applied are reduced.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a compound fertilizer for increasing the yield of lotus roots. Background technique [0002] The lotus root, which is eaten with enlarged underground rhizomes, is the aquatic vegetable with the largest planting area and the highest economic value in China. It is mostly planted in water network areas with good ecological conditions in the Yangtze River Basin. It has rich nutritional value and good medical care value. Lotus root is still a vegetable with no obvious harvest season. It can harvest both green lotus root and mature lotus root. It can be adjusted according to the needs of the market or the economic situation of the family. The harvest period is as long as 9-10 months, which is an ideal The aquatic vegetable varieties have better advantages in the market competition. However, no matter harvesting green lotus root or harvesting a season of mature lotus root,...

Problems solved by technology

However, no matter harvesting green lotus root or harvesting a season of mature lotus root, farmers basically fertilize based on experience and feeling, which not only leads to high nitrogen and phosphorus consumption of lotus root, but also wastes fertilizer resources and increases environmental pollution, which is not conducive to lotus root Sustainability of production
