Special slow-release synergistic high-yield compound fertilizer for grapes

Abstract

The invention relates to the field of compound fertilizers, relates to a special slow-release synergistic high-yield compound fertilizer for grapes. The compound fertilizer is prepared from the following raw materials in parts by weight: 15-18 parts of potassium sulfate, 28-32 parts of diammonium phosphate, 10-12 parts of humic acid, 15-17 parts of chicken manure, 7-8 parts of duck manure, 5-8 parts of bean cake, 10-12 parts of grass carbon, 6-8 parts of calcium superphosphate, 4-5 parts of polylactic acid, 1-3 parts of poly(butylene succinate), 6-8 parts of boron magnesium fertilizer, 5-8 parts of bamboo shoot shell, 2-3 parts of plantain, 1-2 parts of EDTA disodium, 1-3 parts of nano carbon, 2-4 parts of pig hair fine powder and 4-5 parts of assistant. The compound fertilizer contains multiple organic matters and rich minor elements, can provide sufficient nutrients, and is capable of effectively improving the soil environment, loosening the soil and avoiding hardening; and technically, the polylactic acid and poly(butylene succinate) are molten and coated on the nano carbon, pig hair powder and boron magnesium fertilizer to achieve the effect of prolonging the fertilizer efficiency. The compound fertilizer has the advantages of long fertilizer efficiency period, low loss tendency of effective components and efficient fertilizer locking capacity, greatly simplifies the later-period fertilizer application link, and has obvious effects of yield increase and income increase.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a special compound fertilizer for slow-release, synergistic and high-yield grapes. Background technique [0002] Grapes are unique in flavor and rich in nutrition, and are widely welcomed by consumers. The market sales volume is large, and the scope of grape planting is gradually expanding. At the same time, consumers have higher and higher requirements for grape quality. The most effective way is to apply fertilizers with reasonable formula and sufficient nutrients. Most of the existing grape fertilizers have a single nutrient, and supplementary fertilization must be applied at different growth stages of grapes, which will increase the cost of manpower and materials for planting, and also increase the risk of later production reduction. Therefore, enriching the nutrients of fertilizers, prolonging the release cycle of fertilizers, adjusting the soil environment, and controlli...
