Embodiment 1

[0022] Grind 600kg of light shale opal into 800-mesh powder, 400kg of lignite into 400-mesh powder, and mix the two raw material powders uniformly to obtain 1t of the fertilizer for saline-alkali soil modification of the present invention.

[0023] Choose 2000 mus of paddy fields in the rice base of Erdaowan Town, Fuyu County, Heilongjiang Province as the experimental field; 10 mus of them are heavy saline-alkali fields, and the pH value of moisture in the soil is 8.5-9.5, which is used as the fertilizer experimental group field of the present invention; Saline-alkali land and non-saline-alkali land were used as control groups. The conditions of the two groups of fields such as sunshine, temperature and irrigation amount were the same.

[0024] On June 5, 10 mu of experimental group fields and control group fields were sown with rice, and farmyard manure was applied according to conventional cultivation methods; observations were carried out every day after sowing. By June 18...

Abstract

The invention relates to a fertilizer, in particular to a fertilizer for reforming saline soil, which consists of the following components in parts by weight: 2 to 8 parts of light shale opal, 2 to 8 parts of humic acid and 0 to 3 parts of organic fertilizers, wherein the granularity of the light shale opal is between 20 and 1000 meshes, the humic acid is preferably wood coal with the granularitybetween 20 and 1000 meshes, and the granularities of the light shale opal and the wood coal are preferably between 200 and 800 meshes. The fertilizer can provide the nutrients necessary for the growth of plants, can simultaneously improve the soil ingredients of the saline soil, can reduce the salt content, and can increase the soil fertility. The ingredients of the fertilizer of the invention have high yield and low price in China, and can be conveniently and fast obtained. In addition, the fertilizer of the invention has simple process and is convenient to prepare, so the cost is lower and the fertilizer can be easily popularized.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a fertilizer which can be used to transform saline-alkali land. Background technique [0002] Saline-alkali land is a type of salt accumulation, which refers to the land where the salt content affects the normal growth of crops. According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil. The degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. [0003] A soil with a salinity of 3‰ is a saline-alkali land, and a soil with a salt content of more than 6‰ is a severely saline-alkali land. The pH value of the water in the soil of severe saline-alkali soil exceeds 8.5, which causes soil compaction and a...
