preparation example Construction

[0038] A preparation method for improving compound fertilizer in saline-alkali land, comprising the following steps:

[0039] Step 1: taking raw materials by weight;

[0040] Step 2: pulverize the black alum, desulfurized gypsum, nitrogen, phosphorus and potassium compound fertilizer, boric acid, sieve, mix with organic fertilizer, pack, and sterilize to obtain A bag;

[0041] Step 3: Mix the Trichoderma agent, Bacillus subtilis agent, and Bacillus licheniformis agent evenly, pack them, and obtain a B package.

[0042] Wherein, the fermentation method of the organic fertilizer is to weigh straw powder, oily cake, fish bone powder, bentonite and fermentation powder by weight; after diluting the fermentation powder with water for 10-20 times, mix it with straw powder, oily cake Cake, fish bone meal and bentonite are mixed evenly, and the moisture content is controlled to 40-60%, fermented at 20-40°C for 20-40 days to obtain the product.

[0043] The sieve screened in the step ...

Abstract

The invention discloses a compound fertilizer for improving saline-alkali soil and solves the problem that an organic fertilizer in the prior art cannot continuously improve soil condition of the saline-alkali land for a long time. The compound fertilizer disclosed by the invention comprises a bag A and a bag B, wherein the bag A is prepared from the following raw materials in parts by weight: 10 to 15 parts of black alum, 5 to 12 parts of flue gas desulfurization gypsum, 40 to 60 parts of organic fertilizer, 12 to 30 parts of boric acid and 14 to 40 parts of nitrogen phosphorus potassium compound fertilizer, and the bag B is a biological bacterium agent which is prepared from the following ingredients in parts by weight: 10 to 15 parts of trichoderma agent, 20 to 50 parts of bacillus subtilis agent and 20 to 30 parts of bacillus licheniformis agent. The compound fertilizer disclosed by the invention has an effect of continuously improving soil condition for a long time.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a compound fertilizer for improving saline-alkali land. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high. [0003] In the process of utilization, saline-alkali land can be divided into light-saline-alkali land, moderate-saline-alkali land and heavy-saline-alkali land. Light saline-alkali land means that its emergence rate is 70%-80%, and its salt content is less than 3 per thousand; heavy ...
