Substrate capable of improving acidity of soil of aquatic plant wetland

Abstract

The invention provides a substrate capable of improving acidity of soil of an aquatic plant wetland. The substrate is characterized by comprising the following components in parts by weight: a soil conditioner, an additive A, an additive B and an additive C, wherein the additive A comprises the following components in parts by weight: 2-6 parts of ground phosphate rock, 5-8 parts of limestone, 28-136 parts of alkaline substrate, and 4-8 parts of bentonite; the additive B is a soil pH conditioner; the additive C is an alkaline soil fungicide. With the adoption of the substrate, the pH of the soil can be kept from 5.0 to 7.5 and is kept in a stable state; the difference between acidity and alkalinity is small; the substrate is applicable to long-term growing of southern aquatic plant in thewetland.

Description

technical field [0001] The invention relates to the technical field of soil acidity improvement, in particular to a substrate for improving the soil acidity of aquatic plant wetlands. Background technique [0002] Southern wetland soil is too acidic, and it is very common that some plants cannot be grown. For example, Chinese patent 200810058603.1 discloses a method for improving acidic soil with a substrate, which belongs to the field of soil improvement technology. The method is composed of seven steps: substrate production, pH value measurement, substrate dosage determination, substrate application time, soil moisture control, substrate application operation, and soil preparation before planting. Its substrate is suitable for planting in tropical areas, fast-growing, high-yield, and sustainable use. It is developed through processes such as drying and crushing, and fermentation with the stock solution of Dadiwang living bacteria. By determining the amount of substrate ne...

Problems solved by technology

[0004] In order to overcome the situation in the prior art that the southern wetland soil is too acidic, some plants cannot be planted, and the adjustable range of the pH value is too large, and the span between acidity and alkalinity is relatively large, which easily affects the growth of aquatic plants in the wetland. Growth and other problems, the present invention provides a substrate for improving the acidity of aquatic plant wetland soil
