Preparation method of nitrogen-phosphorus synergist

Abstract

The invention provides a nitrogen-phosphorus synergist containing loach and mucus hydrolysate thereof, and a preparation method and application of the nitrogen-phosphorus synergist. The nitrogen-phosphorus synergist containing the loach and the mucus hydrolysate thereof comprises the following components in parts by weight: 30-45 parts of the loach and the mucus hydrolysate thereof, 30-60 parts ofblack chokeberry pomace, 5-15 parts of nostoc sphaeroides proteoglycan, 15-30 parts of potassium fulvate, 15-40 parts of polyaspartic acid, 1-5 parts of cyclohexylphosphoric triamide, and 0.5-5 partsof 3,4 dimethylpyrazole, 1-6 parts of sodium alpha-naphthylacetate, 3-9 parts of brassinolide and 2-5 parts of poly-gamma-glutamic acid. The planting test shows that by the nitrogen-phosphorus synergist, the yield of protected vegetables can be increased, use of nitrogen and phosphorus fertilizers is reduced, the contents of available phosphorus and available nitrogen in soil are increased, the quality of the soil can further be improved, and soil-borne diseases are inhibited.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a nitrogen and phosphorus synergist, a preparation method and an application. Background technique [0002] In order to pursue high yields of crops such as grain and vegetables, farmers often use large amounts of fertilizers such as nitrogen and phosphorus, so the input of nitrogen and phosphorus in farmland soil is far greater than the demand of crops. If things go on like this, the nutrient content in the soil will continue to accumulate, the absorption and utilization rate of nitrogen and phosphorus by crops will decrease, and the loss of nitrogen and phosphorus will be serious. This will not only cause waste of nutrients, but also bring serious pollution risks to soil, groundwater, and farmland ecological environment. In order to reduce nitrogen and phosphorus pollution and achieve efficient use of nutrients, in addition to reducing the input of nitrogen and...
