Saline-alkali-resistant bio-insecticidal compound fertilizer containing seaweed and preparation method thereof

Abstract

The invention discloses a saline-alkali-resistant bio-insecticidal compound fertilizer containing seaweed and a preparation method thereof. The fertilizer is prepared from rice pole, peanut seedling,seaweed, sargentgloryvine stems, azedarach, fructus cnidii, fructus dauci carotae, ferula asafoetida, viola dissecta, herba siegesbeckiae, selfheal, animal excrement, EM bacterial liquid, an EM nutrient solution, an urease inhibitor, a humic acid silicon fertilizer, zinc sulfate, magnesium sulfate, a calcium fertilizer, a nitrogen fertilizer, a phosphate fertilizer, desulfurized gypsum, ammonium potassium fulvate and the like through fine selection, grinding, decocting, ultrafine grinding, enzymatic hydrolysis, centrifugation, fermentation, mixing and the like. The compound fertilizer has thefunctions of salt-alkali resistance and fertilization of fertile soil, the sustainable productivity of soil is improved and the insecticidal sterilization function of soil can be achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a compound fertilizer containing seaweed anti-salinization biological insecticide and a preparation method thereof. Background technique [0002] For China, which has one-fifth of the world's population but less than 9% of the world's arable land, how to ensure food security is a major issue. China currently has 1.8 billion mu of arable land. It is very difficult to increase grain production by increasing the area of ​​arable land. So asking for grain from low- and medium-yield fields and obstructed soils is a solution to food security. According to the analysis data of the Chinese Academy of Sciences, in the four provinces (cities) of Hebei, Shandong, Liaoning and Tianjin in the Bohai Rim region, there are more than 40 million mu of medium and low yield fields and more than 10 million mu of saline-alkali wasteland. If the constraints of lack of fresh water resourc...

Problems solved by technology

[0005] At present, the chemical fertilizers used in agricultural prevention and control of pests and crops are mainly mixed with chemical agents and toxic pesticides, applied to the soil or crops, and used for a long time year after year. A large amount of pesticides and fertilizers have caused the pests to develop drug resistance. , Soil compaction, salinization, soil-borne diseases, etc. have caused more and more serious losses to agricultural production, polluted water sources, soil and crops, reduced the quality of agricultural products, and excessive pesticide residues have seriously affected people's physical and mental health and the competition of my country's agricultural products in the international market force
