Abstract

A microcapsule suspension fertilizer having sterilizing effects for saline-alkali land is provided. The microcapsule suspension fertilizer comprises following components by mass: 10-12 parts of fumaric acid, 12-15 parts of biochemical fulvic acid, 5-8 parts of glutamate, 8-12 parts of humic acid, 2-4 parts of a trace element fertilizer, 2-4 parts of organosilicon, 5.1-5.5 parts of a capsule wall material, 18-22 parts of trifloxystrobin, 15-18 parts of mineral oil, 3-5 parts of xanthan gum, 2-3 parts of calcium dodecylbenzenesulphonate, 3-6 parts of cetyl alcohol and 40-50 parts of water. Applications of the microcapsule suspension fertilizer in plantation of Chinese scholar tree are also provided. The beneficial effects of the microcapsule suspension fertilizer and the applications are that the soil salt content is reduced to 0.22-0.28%, the soil pH is reduced to 7.3-7.6, the microcapsule suspension fertilizer is used for plantation of the Chinese scholar tree in saline-alkali land, the survival rate of transplanting of the Chinese scholar tree is 97.8-98.7%, and the Chinese scholar tree is early in sprouting and late in defoliation.

Description

technical field [0001] The invention provides a fertilizer and its application in the planting of Chinese pagoda tree, in particular to a microcapsule suspension fertilizer with bactericidal effect in saline-alkali land and its application in the planting of Chinese pagoda tree, belonging to the technical field of soil fertilizer. 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. Soil salinization is a worldwide problem. The area of ​​saline soil in the world is about 1 billion hectares, and my country has 99.13 million hectares, or about 1.47 billion mu; Nearly 500 million mu of land has been lost or abandoned due to salinization, mainly concentrated in the arid and semi-arid regions of North China, Northwest China and Northeast China. In addition, during the cultivation process, the long-term excessive application of chemical fertilizers will lead to the inte...
