A kind of bio-organic fertilizer specially used in saline-alkali land and its preparation method and application

Abstract

The invention discloses a special bio-organic fertilizer for saline-alkali soil as well as a preparation method and application of the special bio-organic fertilizer. The special bio-organic fertilizer is prepared from the following raw materials in parts by weight: 25-50 parts of edible mushroom wastes, 20-40 parts of animal dung, 0.5-8 parts of organic material leavening agent and 5-12 parts of bioactive substances. The preparation method comprises the following steps of smashing edible mushroom wastes, and then, mixing the smashed edible mushroom wastes and animal dung; next, adding an organic material leavening agent; uniformly mixing, and placing the mixture into a fermentation tank to carry out high-temperature aerobic fermentation for 20-30 days; uniformly mixing the fermented material and bioactive substances according to a certain ratio, then, smashing and drying to obtain the bio-organic fertilizer. The special bio-organic fertilizer for the saline-alkali soil, disclosed by the invention, is applied to modification of medium and low yield fields of the saline-alkali soil. The bio-organic fertilizer for the saline-alkali soil is complete in nutrient element, durable in fertilizer efficiency and capable of taking effects of increasing the utilization rate of the fertilizer, improving the saline-alkali soil and improving the quality of crops.

Description

technical field [0001] The invention belongs to the field of fertilizers, and relates to a bio-organic fertilizer specially used for saline-alkali land, a preparation method and application thereof. Background technique [0002] Fertilizers are the food of crops, and rational application of fertilizers is one of the important factors to ensure high and stable crop yields and promote the rapid development of my country's agriculture. Fertilizers are mainly divided into inorganic fertilizers and organic fertilizers. Inorganic fertilizers are also called chemical fertilizers, such as nitrogen fertilizers, phosphorus fertilizers, and potassium fertilizers. In modern agriculture, due to the pursuit of high agricultural yields, a large number of chemical fertilizers and pesticides are used. When these chemicals are applied to the soil, the physical, chemical and biochemical properties of the soil deteriorate sharply, the soil hardens, the microorganisms are eliminated, the loss of...

Problems solved by technology

Because edible fungus waste usually has its special physical and chemical properties and rich nutrients, people began to pay attention to using it to improve saline-alkali soil, so as to reduce economic investment, reduce pollution, and reduce soil salinity, pH value, alkalization, etc. degree, changing soil properties, reducing bulk density, increasing porosity and increasing soil nutrients have achieved different degrees of effect, but it still does not have the advantages of improving soil structure, reducing soil salinity and improving soil fertility and biological activity.
