Restoration modifier for treating soda saline and alkaline land and fertilizing saline and alkaline soil

Abstract

The invention provides a restoration modifier for treating soda saline and alkaline land and fertilizing saline and alkaline soil. The restoration modifier is prepared from 25-35% of pretreated organic matter garbage, 30-50% of activated humic acid materials, 15-25% of rock mineral grain powder, 2-8% of solid hydrochloric acid powder and 2-8% of starch matter. The restoration modifier is particle powder with the water content being 25-30%. The organic matter garbage comprises organic matter garbage generated in daily life of the human beings, waste leftovers generated in the catering industry, straw of various crops in agricultural production, stems and leaves of various wild vines, excrement of people, livestock and poultry and leftovers of livestock, poultry and fishes slaughtered by the human beings. The activated humic acid materials comprise coal gangue, peat and brown coal. The rock mineral particle powder is prepared from natural rock particle powder with the particle size being 0.002-0.01 mm and mainly prepared from road building dead rock powder such as zeolite, limestone, quartzite, micalex, gypsum, decomposed coal and calcium carbonate. Solid hydrochloric acid is powdery. Starch is non-edible starch or edible starch. During application, the restoration modifier can be mixed and matched with traditional farmyard manure for use. The applying amount of the restoration modifier is 3-7 tons per mu.

Description

Technical field [0001] The invention relates to a repairing and improving agent for treating soda-type saline-alkali soil and fertilizing the saline-alkali soil, belonging to the category of agricultural technology, in particular to a soda-type saline-alkali soil repairing and improving technology. Background technique [0002] Nowadays, there are large areas of soil in my country that have caused soil salinization or salinization due to various reasons, including natural and natural environmental factors, and many of them are caused by excessive human intervention and improper management. This high price of destroying the ecological environment in exchange for rapid social and economic development is also the old path that most industrialized countries have taken, and it is also a serious problem facing most developing countries. [0003] "Land determines the destiny of mankind", "fertile soil nourishes people, poor soil hurts people, and dead soil harms people" are the common cog...

Problems solved by technology

[0008] In order to achieve the above purpose, many inventors have proposed some measures to improve soil activity and increase soil organic fertility, but most of the methods are still in a relatively primitive stage, because most of the soil was originally fertile fields, and now After the land becomes obviously barren and barren, the value of the agricultural land has been completely exhausted and degraded by increasing the application of organic fertilizers. effect
