Organic fertilizer for modifying soil, saving water, resisting drought and fixing nitrogen

Abstract

The invention discloses a modified soil water-saving drought-resisting nitrogen fixation fertilizer of organics, which comprises the following parts: 10-60% coal, 1-5% charcoal and 35-85% charring straw. The invention increases capillary porous soil and capillary porous water, which utilizes rainfall completely to adsorb free nitrogen and ammonia in the soil.

Description

technical field

[0001] The invention relates to an organic fertilizer, in particular to a water-saving, drought-resistant and nitrogen-fixing fertilizer for improving soil with organic matter. Background technique

[0002] At present, agricultural water saving basically adopts sprinkler irrigation, drip irrigation and other means, due to its high cost, water source, power supply and terrain factors and other limitations, the development is very slow. At present, there is a lack of low-cost water-saving technology at home and abroad. In my country, 60% of the dry land relies on nature to survive, and 40% of the irrigated land is flooded with floods. Agricultural water is extremely wasteful. In the 1990s, wheat was planted with plastic film in dry areas. It is difficult to recycle, and the white pollution is extremely serious, so it is no longer used. At present, some departments use crushed straw to cover wheat and corn to achieve the purpose of water saving and drought resis...
