Potassium magnesium humate soil conditioner for secondary salinized land, and production method thereof

Abstract

The invention discloses a potassium magnesium humate soil conditioner for secondary salinized land. The soil conditioner comprises, by mass, 1000-1500 parts of rhizome of blue algae, 1000-1300 parts of sodium alginate, 1000-1500 parts of a water-retaining agent, 800-1200 parts of phosphate rock powder, 1200-1800 parts of nano-carbon, 35-50 parts of potassium hydroxide, 10-20 parts of humic acid raw powder, 50-80 parts of magnesium sulfate, 60-90 parts of a compound enzyme preparation and 30-60 parts of a composite inoculant. Potassium magnesium humate produced by using the humic acid raw powder, potassium hydroxide and magnesium sulfate has the advantages of no byproducts, high operability, and effectiveness in control of the production cost. The potassium magnesium humate produced throughthe method contains the magnesium element and potassium element needed by crops, so the absorption and utilization of the magnesium element and potassium element by the crops are effectively promoted. The potassium magnesium humate contains organic matters, so the soil is improved to a certain degree.

Description

technical field [0001] The invention relates to a magnesium potassium humate secondary saline-alkali soil improver and a preparation method thereof. Background technique [0002] Soil secondary salinization, also known as "secondary salinization", refers to the process of turning good cultivated land into "salinization" due to unreasonable cultivation and irrigation measures and changes in vegetation. It 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 coconut bran drainage system in the farmland is not smooth, and a large amount of coconut bran irrigation has raised the level of underground coconut bran, increasing the speed of underground coconut bran moving upward through soil capillaries and the underground coconut bran. The evaporation of bran increases the accumulation of salt in the underground coconut bran and the subsoil to...

Problems solved by technology

[0005] At present, most of the commonly used saline-alkali soil amendments contain very single ingredients. Long-term use will cause soil compaction, loss of nitrogen, phosphorus, and potassium in the soil, slow crop growth, decline in resistance to diseases and insect pests, and lower yields.
