Grape pomace functional compound fertilizer and preparation method thereof

Abstract

The invention discloses a grape pomace functional compound fertilizer which is mainly prepared from the following raw materials in parts by weight: 50.1-77.8 parts of an inorganic salt fertilizer, 22-32 parts of wine grains, 1.5-3.9 parts of an antibiotic fertilizer, 1.5-3.2 parts of polyvinyl alcohol, 1-2.5 parts of polyacrylamide, 0.25-0.6 part of citric acid and 0.02-0.14 part of compound sodium nitrophenolate. The grape pomace functional compound fertilizer disclosed by the invention is balanced in nutrition, can supply enough nutrients to corn fields and can improve quality and yield of corns, and the produced corn grains are big and full and have good in taste and the yield is high. The grape pomace functional compound fertilizer can enhance cold-resisting, drought-resisting and disease resisting capabilities of corns, has a good ecological efficiency, solves the problem that the corn field is rough in soil texture and poor in water retaining capacity, and can supply nutrients to corns, coordinate nutrient balance of soil and improve the quality and yield of corns. A preparation method of the grape pomace functional compound fertilizer disclosed by the invention uses easily available raw materials, is simple to operate and easy to implement, and the prepared special fertilizer is stable and reliable in quality and facilitates full absorption of nutrient elements by corns and increase of the yield of corns to a great extent, and the rate of growth reaches up to 22.73-32.52%.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemical fertilizers, in particular to an organic ecological fertilizer specially used for grapes and a preparation method thereof. technical background [0002] The Hexi Corridor in Gansu Province has unique natural environmental conditions. In the past 10 years, it has attracted more than 90 seed industry groups at home and abroad, established a corn seed production base of 1.5 million mu, and has an annual seed production of 660 million kg, becoming the largest in the country. Corn seed production base. Seed production corn has a large planting area and a long continuous cropping period. The ratio of chemical fertilizer nitrogen and phosphorus input to organic fertilizer nitrogen and phosphorus input is 1:0.28. The increase in seed production corn production mainly depends on the application of chemical fertilizers. Compound fertilizers circulating in the market The active ingredients and...

Problems solved by technology

Seed production corn has a large planting area and a long continuous cropping period. The ratio of chemical fertilizer nitrogen and phosphorus input to organic fertilizer nitrogen and phosphorus input is 1:0.28. The increase in seed production corn production mainly depends on the application of chemical fertilizers. Compound fertilizers circulating in the market The active ingredients and proportions are not in line with the nutrient status of corn farming in Gansu Province. Long-term large-scale application of chemical fertilizers on the market causes the calcium ions adsorbed on the soil colloid to be replaced by ammonium ions, and the soil aggregate structure is destroyed, resulting in soil compaction; in addition, the market The active ingredients and proportions of the compound fertilizers circulated above do not conform to the current nutrient status of corn production and the absorption ratio of corn to nutrients, and do not have the effect of improving soil, resulting in a decline in the quality and yield of seed production corn
