Abstract
The invention provides a high-selenium fertilizer for saline-alkali soil. The fertilizer comprises the following components: maleic anhydride, citric acid, amino acid salt, biochemical fulvic acid, humic acid, trace element fertilizer, potassium selenite, suaeda powder, attapulgite, vermiculite powder, mineral oil and methyl salicylate. The fertilizer provided by the invention can be used for effectively perfecting moderate and severe carbonate saline-alkali soil, and after improvement, in a soluble salt each 100 g of soil, the content of soda is 0.2-0.3 mg of equivalent weight, the salt content of the soil is 0.15-0.2%, the pH of the soil is 7.1-7.4, the content of effective potassium is 110-112 mg/kg, the total amount of trace elements is 30-32 mg/kg, the microbial content in the soil is improved by 50-55%, and the content of selenium can be up to 0.80-0.82 mg/kg.
Description
technical field [0001] The invention provides a fertilizer and its application in Chinese tallow planting, in particular to a high-selenium fertilizer for saline-alkali land and its application in Chinese tallow planting, and belongs to the technical field of soil fertilizers. Background technique [0002] Large areas of saline-alkali land in my country have not been well developed and utilized, mainly because: saline-alkali land has high salinity, low microbial content, and insufficient nutrient content. The survival rate of plants in these saline-alkali lands is not high, and it is difficult to grow normally after survival. [0003] There are 520 million mu of saline-alkali land in my country, and 260 million mu of potential saline-alkali soil. The improper development and utilization of these soils, especially carbonate saline-alkali land, will cause secondary saline-alkali land. Our country has a large area of saline-alkali land, so we can adapt to local conditions an...
