Humic acid water flush fertilizer applicable for secondary salinization lands in Yellow River irrigated areas

Abstract

The invention discloses a humic acid water flush fertilizer applicable for secondary salinization land in Yellow River irrigated areas. The fertilizer is prepared from, by weight, 150-200 parts of bagasse, 0.5-2 parts of alginate oligosaccharide, 30-40 parts of livestock manure, 16-25 parts of microbial agent, 20-40 parts of humic acid, 10-20 parts of boracic acid, 10-15 parts of diatomite, 10-15 parts of magnesium sulfate and 10-20 parts of naphthylacetic acid. According to the humic acid water flush fertilizer applicable for secondary salinization of lands in Yellow River irrigated areas, the raw materials are reasonable in matching. Sedimentation and antagonism among the raw materials are overcome, soil physical and chemical properties are improved, hardening is removed, soil is loosened, the pH value of the soil is adjusted and a soil structure is improved. By adding alginate oligosaccharide in the water flush fertilizer, the humic acid water flush fertilizer applicable for secondary salinization land in Yellow River irrigated areas continuously provides nutrients for plants, has long action time, boosts each stage indispensable to growth cycles of the plants without any influence on the environment, and can further form effective protecting films on the surfaces of plant bodies to enhance disease resistance and tolerance resistance of the plant bodies.

Description

technical field [0001] The invention relates to a special improved organic fertilizer for saline-alkali land, in particular to humic acid fertilization suitable for secondary saline-alkali land in Yellow River irrigation areas. 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 b...
