Problems solved by technology

The main reason for the low effective utilization rate of ordinary fertilizers is that they are easily soluble in water and quickly dissolve in water after being applied to the soil, and nutrients such as N, P, and K are released in a relatively short period of time at a dose far greater than the amount that crops can absorb.

Embodiment 1

[0011] A kind of slow-release fertilizer that increases soil humus, is characterized in that, each component of raw material is composed as follows according to weight part:

[0012] 45 parts of xylose waste residue, 15 parts of ammoniated waste residue, 20 parts of rice bran, 8 parts of bran, 5 parts of ginkgo leaf powder, 1 part of choline chloride, calcium hydrogen phosphate and stone powder according to the weight ratio of 1:3 Mineral composition 3 0.4 parts of mixed amino acids composed of methionine and threonine in a weight ratio of 1:2, and 2 parts of additives composed of ageratum and gentian in a weight ratio of 3:5.

[0013] The ammoniated waste residue is to add 150 parts by weight of saturated concentrated ammonia water and 200 parts by weight of water to medium seaweed. The seaweed is calculated on a dry weight basis, and reacted for 2 hours at a temperature of 100°C and oxygen is fed to maintain a pressure of 1.2Mpa, and the pH is adjusted. After reaching 7.0, d...

Abstract

The invention discloses a sustained-release fertilizer capable of increasing soil humus. The fertilizer is composed of the following raw materials, by weight: 45-55 parts of xylose residue, 15-20 parts of ammoniated waste residue, 20-26 parts of rice bran, 8-12 parts of wheat bran, 5-7 parts of gingko leaf powder, 1-3 parts of choline chloride, 3-5 parts of minerals composed of calcium hydrogen phosphate and stone powder with a weight ratio of 1:3, 0.4-0.6 part of mixed amino acids composed of methionine and threonine with a weight ratio of 1:2, and 2-4 parts of an additive composed of wrinkled gianthyssop herb and radix gentianae with a weight ratio of 3:5. With the formula provided by the invention, the fertilizer assists in supplementing the nutrition needs of soil, and increasing soil organic matters. After a slow microbial decomposition process, the fertilizer causes no pollution to the environment, and assists in increasing soil humus. The fertilizer has a good effect in ameliorating barren soil and desertified soil. The fertilizer comprises and can slowly release N, P and K for plant growth. The fertilizer has extremely low loss rate, high plasticity and high shaping capability. With the fertilizer, irrigation frequency can be reduced, and water needed by plant growth can be maintained.

Description

technical field [0001] The invention belongs to the technical field of feed formula, in particular to a slow-release fertilizer for increasing soil humus. Background technique [0002] According to data reports, the average utilization rate of chemical fertilizers in developed countries is 50% to 60%, and the utilization rate of nitrogen fertilizer is 50% to 70%; while the utilization rate of nitrogen fertilizer and phosphorus fertilizer in China is 30% to 35% and 10% to 25%, respectively. It is 15% to 20% lower than developed countries, and the fertilizer loss reaches 45% (35 billion to 60 billion yuan per year), and more than 80% of the phosphate fertilizer is fixed in the soil. The main reason for the low effective utilization rate of ordinary fertilizers is that they are easily soluble in water and quickly dissolve in water after being applied to the soil, and nutrients such as N, P, and K are released in a relatively short period of time at a dose far greater than the a...
