Ferment-calcium humate organic fertilizer for secondary saline-alkali land and preparation method thereof

Abstract

The invention discloses a ferment-calcium humate organic fertilizer for secondary saline-alkali land. Raw material formula of the fertilizer comprises, by weight, 1000-1500 parts of blue algae, 1000-1300 parts of sodium alginate, 1000-1500 parts of tobacco waste, 800-1200 parts of ground phosphate rock, 1200-1800 parts of nano-calcium carbonate, 35-50 parts of potassium hydroxide, 10-20 parts of calcium humate, 50-80 parts of magnesium sulfate, 60-90 parts of a complex enzyme preparation and 30-60 parts of ferment bacteria. By adding calcium humate, sodium ions in soil can be removed, and humic acid neutralizes a certain alkalinity. After the fertilizer is applied into soil, soil alkalization is remarkably alleviated, and available nitrogen nutrient of soil is increased. Ferment bacteria is an ideal compost external inoculant, which can enhance the capability of decomposing organic matter and inorganic matter such as cellulose, indissolvable mineral matter, etc.

Description

Technical field [0001] The invention relates to an enzyme calcium humate organic fertilizer used in secondary saline-alkali soils and a preparation method thereof. Background technique [0002] Soil secondary salinization is also called "secondary salinization", which refers to the process of turning good farmland into "salinization" due to unreasonable human cultivation and irrigation measures and changes in vegetation. Mainly occurs in my country's North China Plain, Songliao Plain, Hetao Plain, Weihe Plain and other places. There are three main reasons for the formation of secondary salinization: First, the system of discharging coconut chaff in farmland is not smooth. A large amount of coconut chaff irrigation raises the level of underground coconut chaff and increases the upward movement speed of underground coconut chaff through soil capillary. The evaporation of bran increases the accumulation of salt in the underground coconut bran and the underlying soil to the surface ...

AI Technical Summary

Problems solved by technology

[0006] At present, most of the commonly used secondary saline-alkali soil fertilizers contain very single ingredients. Long-term use will cause soil compaction, nitrogen, phosphorus, and potassium loss in the soil, slow crop growth, decline in resistance to diseases and insect pests, and lower yields.
