Abstract

A high-selenium fertilizer for saline-alkali land is provided. The high-selenium fertilizer comprises following components: urea, dipotassium phosphate, humic acid, a trace element fertilizer, suaeda glauca powder, attapulgite, vermiculite powder, potassium selenite, maleic anhydride, citric acid, amino acid salts, biochemical fulvic acid, mineral oil and methyl salicylate. The fertilizer can effectively improve the saline-alkali land in a planting zone. After improvement, the salt content of soil layers having depth of 0-30 cm is 0.15-0.23%, the soil pH is 7.2-7.4, the soil humus content is 0.7-0.75 g / kg, the total nitrogen content of the soil is 0.52-0.58%, the content of trace elements is 28-30 mg / kg, and the selenium content is 0.66-0.78 mg / kg.

Description

technical field [0001] The invention provides a fertilizer and its application in the planting of neem, in particular to a high-selenium fertilizer for saline-alkali land and its application in the planting of neem, belonging to the technical field of soil fertilizers. 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. [0003] At present, with the development of science and technology, we should not only see the negative side, but should regard it as a very precious land resource, because many organisms including plants, including microorganisms, can adapt to this environment, and more and more More and more scientific and technological workers are devoting themselves to the...
