Humic acid-based conditioner used for conditioning Yellow River irrigating district saline and alkaline land

Abstract

The invention discloses a humic acid-based conditioner used for conditioning Yellow River irrigating district saline and alkaline land. The humic acid-based conditioner comprises, by weight, 150-200 parts of watermelon peel, 0.5-2 parts of seaweed oligosaccharides, 30-40 parts of livestock manure, 16-25 parts of a microbial agent, 20-40 parts of humic acid, 10-20 parts of citric acid, 10-15 parts of needle leaf soil, 10-15 parts of magnesium sulfate and 10-20 parts of rooting hormone. Reasonable matching of all raw materials in the invention overcomes the precipitation and antagonism effect among the raw materials, improves the physical and chemical properties of soil, eliminates soiling, loosens the soil, adjusts the pH value of the soil, and improves the structure of the soil. The seaweed oligosaccharides added to a water flush fertilizer can continuously provide nutrients for plants, have a long-time action effect, promote all stages of the growth cycle of plants, have no influences on environment, form an effective protection film on the surface of a plant corpus, and enhances the disease and tolerance resistance of the plant corpus.

Description

technical field [0001] The invention discloses a humic acid-based conditioning agent for conditioning the saline-alkali land in the Yellow River irrigated area. Background technique [0002] With the continuous development of the Yellow River irrigation area, many difficulties have been encountered in the improvement and utilization of saline-alkali land. In order to make full use of the land in the Yellow River irrigated area, people have adopted various methods such as ditches to reduce water and drain salt, inject fresh water to pressurize salt, and set up a spray layer to prevent seepage and separate salt, etc. . However, due to the compaction and barrenness of saline-alkali soil, low fertility and high soil pH value, it is not conducive to plant growth. [0003] The main reasons for the formation of secondary saline-alkali land are: [0004] (1) In arid and semi-arid areas, the salt contained in the bottom soil and groundwater, due to ground evaporation, will cause t...
