Super absorbent soil reclamation plant growth substance and preparation method thereof

Abstract

The invention relates to a soil reclamation plant growth culture matrix and a preparation method thereof. The matrix comprises the following components: 50 to 70 weight percent of UF foamed plastics, 30 to 50 weight percent of straw powder, 1 to 2 weight percent of decomposed organism organic fertilizer, 1 to 2 weight percent of 40 percent ammonium bicarbonate solution, 0.5 to 0.7 weight percent of diammonium phosphate, and 0.2 to 0.5 weight percent of potassium chloride. The matrix has water retention property, nutrient preserving property, thermal insulation and ventilated permeability so asto prevent the water and nutrient from losing, thereby creating a good hot bed suitable for the growth of seeds and plants; besides, the matrix can carry out effective ecological compensation to plants during dry periods, and simultaneously lead the root systems of plants to grow fast and take root so as to absorb the water under surface layer and create beneficial conditions for the future growth of plants. Taking poplars as an example, the survival rates of growing in desert, grassland and improved kaline soil are respectively 86.7 percent, 93.3 percent and 96.7 percent.

Description

technical field [0001] The invention relates to a plant cultivation substrate and a preparation method thereof, in particular to a soil quality improvement plant growth promotion cultivation substrate and a preparation method thereof. Background technique [0002] In recent years, due to the increasingly serious environmental pollution and the deteriorating ecological environment, the state has vigorously called for afforestation, returning farmland to forests, and sealing sand for afforestation. Due to the low water content, no water retention and low soil fertility of the most basic plant cultivation substrate in the area, it cannot meet the fertility elements required for plant growth, resulting in extremely low plant survival rate. For this reason, the applicant of this application has patent number: 200510046937.3, Publication number: CN1736936, Announcement date: On February 22, 2006, the Chinese invention patent urea-formaldehyde foam insulation board was used as a ra...

[0002] In recent years, due to the increasingly serious environmental pollution and the deteriorating ecological environment, the state has vigorously called for afforestation, returning farmland to forests, and sealing sand for afforestation. Due to the low water content, no water retention and low soil fertility of the most basic plant cultivation substrate in the area, it cannot meet the fertility elements required for plant growth, resulting in extremely low plant survival rate. For this reason, the applicant of this application has patent number: 200510046937.3, Publication number: CN1736936, Announcement date: On February 22, 2006, the Chinese invention patent urea-formaldehyde foam insulation board was used as a raw material to develop a new high water-absorbing soil quality improvement plant growth substrate
