A microcapsule suspension fertilizer having sterilizing effects for saline-alkali land and applications thereof in plantation of Chinese scholar tree

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 Sophora japonica planting, specifically relates to a microcapsule suspended fertilizer with bactericidal effect in saline-alkali soil and its application in Sophora japonica planting, and belongs 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. Soil salinization is a worldwide problem. The area of ​​saline soil in the world is approximately 1 billion hectares. my country has 99.13 million hectares, or approximately 1.47 billion acres. Nearly 100 cities across the country are located in saline-alkali land distribution areas. Due to the Salinization has resulted in nearly 500 million acres of reduced yields and abandoned farmland, mainly in arid and semi-arid areas such as North China, Northwest China, and Northeast China. In addition, du...

Problems solved by technology

[0004] Existing soil improvers have played an important role in the process of improving saline-alkali, but there are still the following deficiencies: (1) The function is single and cannot have a bactericidal effect at the same time; (3) Planting plants after soil improvement, the transplanting survival rate of plants is low, the growth is small, and the accumulation of beneficial ingredients in plants is less
