Problems solved by technology

However, the growth of tea trees is inseparable from the application of chemical fertilizers. Unabsorbed chemical fertilizers will make the soil alkaline and affect the growth of tea trees
Alkaline soil amendments are often used to change soil pH, but the existing alkaline soil amendments are less effective and more expensive

Abstract

The invention relates to the technical field of soil improvement, in particular to an alkaline soil improvement agent. The alkaline soil improvement agent is prepared from, by weight, 40-60 parts of modified peat, 15-25 parts of curing agent, 5-15 parts of rice bran, 4-10 parts of super absorbent resin, 3-12 parts of disodium hydrogen phosphate, 2-10 parts of acetic acid, 10-18 parts of cornstalk, 3-10 parts of yeast, 15-25 parts of polyacrylamide polymer, 1-6 parts of bamboo fiber, 4-13 parts of maleic anhydride and 0.1-0.9 part of nitrobacterium. The alkaline soil improvement agent is long in soil retention time, high in using efficiency, low in production cost and particularly applicable to soil with the pH being 7.3-8.1.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an alkaline soil improver. Background technique [0002] Tea tree is a shrub or small tree, with glabrous twigs. The leaves are leathery, oblong or oval, and can be used to make tea. Tea trees have high requirements on soil. Generally, the soil layer is more than 1 meter thick without limestone, sandy soil with good drainage, organic matter content of 1% to 2%, and good air permeability and water permeability. In addition, the pH value of the soil is preferably 4.5-6.5. However, the growth of tea trees is inseparable from the application of chemical fertilizers. Unabsorbed chemical fertilizers will make the soil alkaline, thereby affecting the growth of tea trees. Alkaline soil improvers are often used to change soil pH, but the existing alkaline soil improvers are less effective and more expensive. Therefore, it is necessary to provide an alkaline soil conditioner t...
