Embodiment 1

[0009] A slow-release fertilizer granule, which is composed of chemical fertilizer slow-release agent and organic fertilizer with a weight ratio of 4:23, wherein the chemical fertilizer slow-release agent is composed of raw materials in parts by weight: calcium superphosphate 4, polyvinyl alcohol 1.34, humic acid 3, phosphoric acid Diammonium 2.3, carbendazim 0.7, EDTA chelated zinc 1.6.

[0010] Among them, the organic fertilizer is composed of the following parts by weight: bean dregs 18, sweet potato leaf powder 8, earthworm powder 5.6, plant straw 6.8, rice bran powder 13, water chestnut 7, stone powder 4, peanut kernel cake powder 3, shell powder 6.8, Tenebrio molitor Powder 3, bagasse 12.

Embodiment 2

[0012] A slow-release fertilizer granule, which is composed of chemical fertilizer slow-release agent and organic fertilizer with a weight ratio of 3:30, wherein the chemical fertilizer slow-release agent is composed of raw materials in parts by weight: calcium superphosphate 2, polyvinyl alcohol 1.4, humic acid 2, phosphoric acid Diammonium 3, carbendazim 0.5, EDTA chelated zinc 2.

[0013] Among them, the organic fertilizer is composed of the following parts by weight: bean dregs 15, sweet potato leaf powder 10, earthworm powder 5, plant straw 8, rice bran powder 10, water chestnut 8, stone powder 3, peanut kernel cake powder 4, shell powder 6, Tenebrio molitor powder 4, bagasse 10.

Embodiment 3

[0015] A slow-release fertilizer granule, which is composed of chemical fertilizer slow-release agent and organic fertilizer with a weight ratio of 6:15, wherein the chemical fertilizer slow-release agent is composed of raw materials in parts by weight: calcium superphosphate 6, polyvinyl alcohol 1.3, humic acid 4, phosphoric acid Diammonium 2, carbendazim 1, EDTA chelated zinc 1.

[0016] Among them, the organic fertilizer is composed of the following parts by weight: bean dregs 20, sweet potato leaf powder 6, earthworm powder 6, plant straw 6, rice bran powder 15, water chestnut 6, stone powder 5, peanut kernel cake powder 2, shell powder 8, Tenebrio molitor Powder 2, bagasse 15.

[0017] The method of fertilization is as follows: as a base fertilizer, it is applied in strips before the ridge is formed, and it is applied at one time, and then the ridge is formed. The fertilization time is more suitable for 10-15 days before the crops are planted.

Abstract

The invention discloses slow-release fertilizer granules which consist of chemical slow-release agents and organic fertilizers in a weight ratio of (3-6):(15-30), wherein the chemical slow-release agents consist of the following raw materials in parts by weight: 2-6 parts of calcium superphosphate, 1.3-1.4 parts of polyvinyl alcohol, 2-4 parts of humic acid, 2-3 parts of diammonium phosphate, 0.5-1 part of carbendazol and 1-2 parts of EDTA (Ethylene Diamine Tetraacetic Acid) helated zinc. As the chemical fertilizers with slow-release effects are combined with the organic fertilizers to form a mixed fertilizer, the slow-release fertilizer granules are high in fertilizer efficiency absorption rate, long in action period and applicable to growth cycles of crops, the yield of crops can be increased by 30%, and the yield and the benefits of the crops can be increased.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a slow-release fertilizer granule. Background technique [0002] Fertilizers are compounds that help plants grow. Slow-release fertilizers refer to fertilizers whose nutrient release rate is much lower than that of instant fertilizers applied to the soil and converted into plant-available nutrients. There are many types and brands of fertilizers on the market. Existing slow-release fertilizers have technical defects such as low fertilizer efficiency and mismatch between release and crop demand, which need to be solved urgently. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a slow-release fertilizer granule, which has reasonable composition, uniform fertilizer effect release, and is suitable for crop growth requirements. [0004] In order to achieve the above invention, the present invention provides the foll...
