Compound fertilizer for improving quality of water chestnuts

Abstract

The invention discloses a compound fertilizer for improving quality of water chestnuts. The compound fertilizer comprises the following raw materials in parts by weight: 30-50 parts of composted chicken dung, 20-30 parts of mushroom dregs, 10-20 parts of fermented cottonseed cakes, 5-15 parts of fishbone dust, 35-45 parts of bean pulp, 6-12 parts of coal gangue powder, 6-10 parts of diatomite, 6-12 parts of charcoal, 4-8 parts of medical stone powder, 2-5 parts of ferrous sulfate, 2-4 parts of zinc sulfate, 3-7 parts of perlite, 9-15 parts of high gluten flour, 20-40 parts of ammonium nitrate, 20-30 parts of plant ash, 30-40 parts of ground phosphate rock and 80-120 parts of compound urea. The various nutrient elements needed for growth of water chestnuts are reasonably compounded, the fertilizer retaining and slow-release properties are excellent, and healthy growth of the water chestnuts can be obviously promoted, so that the effects of improving the yield, improving the quality and increasing economic benefits are achieved. Meanwhile, the addition amount of the fertilizer can be reduced, and the environmental pollution risk caused by improper fertilization is reduced.
