Special ground fertilizer-natural ore fertilizer for alkaline land

Abstract

The invention provides a special base fertilizer-natural ore fertilizer for the saline alkali lands, and the special base fertilizer-natural ore fertilizer is a special fertilizer for improving the saline alkali lands. In recent years, the salinization degree of the soil keeps rising, and the area of saline alkali lands has being expanded and increased at an annual speed of 1.5 percent. The situation brings difficulties to the production and living of people as well as the regional economic development. The special base fertilizer-natural ore fertilizer for the saline alkali lands changes the soil character and activates the land capability factors. Aiming at the five major factors for the development of the saline alkali lands, potash feldspar ore, the phosphate ore, the silicate ore and the organic rock are adopted to produce the special base fertilizer-natural ore fertilizer for the saline alkali lands. The unique crystal structure in the ore changes the situation of saline alkali soil, and the ion exchange lowers the PH value of the soil. The molecule pore preserves water and prevents drought, thereby increasing the soil nutrient. 5 particles of the powder in A bag are fertilized 30 centimeters deep in soil by the 9SF-2.45 type rat channel steppe scarification fertilizer distributor, with 8 tons of fertilizer for each hectare; and the scrap in the B bag is ploughed under 10 to 15 centimeters deep underground by a tractor-propelled five-furrow plough, with 8 to 30 tons of fertilizer for each hectare.

Description

technical field [0001] Special base fertilizer for saline-alkali land—natural mineral fertilizer is a special fertilizer specially researched to improve saline-alkali land. Background technique [0002] The area of ​​saline-alkali land in the west of Jilin Province is 15326.66km 2 , of which, moderate and strong saline-alkali land accounts for 9071.32km 2 Soil salinization is the main obstacle to agricultural production in the Songnen Plain. In recent years, the intensity of soil salinization has been increasing, and the area of ​​saline-alkali land has gradually expanded, increasing at a rate of 1.5% per year. The saline-alkali land has barren fertile land, aggravated the drought, frequent natural disasters such as waterlogging and sandstorms, and the deterioration of the agricultural ecological environment has brought difficulties to the production and life of local farmers and restricted regional economic development. The special base fertilizer for saline-alkali land—...
