Embodiment 1

[0047] In this example, the hilly soil rapid water storage and fertilizer compound material is made of organic materials, salt-resistant water-absorbing and water-retaining materials and graft copolymerization mixed liquid through graft copolymerization and oxygen-avoiding surface cross-linking reaction. The organic material is waste litter and / or poultry manure of the fermentation bed; the graft copolymerization mixture is composed of N, N-methylenebisacrylamide, methanol and water; the salt-resistant water-absorbing and water-retaining material is optional The particle size of the commercially available products is 20-40 mesh, and the concentration is 0.9wt% sodium chloride solution absorption rate of 80 times or more products or self-made products with the same performance. The dosage of each substance is shown in Table 1.

Abstract

The invention discloses a rapid water-storage and fertilization compound material for hill soil and a preparation method of the rapid water-storage and fertilization compound material. The compound material is prepared from organic materials, salt-tolerant water absorption and water retention materials and a graft-copolymerization mixed solution through graft copolymerization oxygen-avoiding surface cross-linking reaction. The preparation method comprises the following steps: (1) preparing the organic materials; (2) preparing the graft-copolymerization mixed solution; (3) carrying out graft copolymerization, namely mixing the organic materials prepared in the step (1) with the graft-copolymerization mixed solution prepared in the step (2), adding the salt-tolerant water absorption and water retention materials, and carrying out the graft copolymerization oxygen-avoiding surface cross-linking reaction; and (4) baking, grinding and drying a reaction product in the step (3), so as to obtain the rapid water-storage and fertilization compound material for the hill soil. According to the rapid water-storage and fertilization compound material, the absorption rate and moisture holding capacity of soil to moisture can be improved, the soil moisture content in the drought season can be increased, the loss of fertilizer water caused by the surface runoff of hill slopes in the rainy season can be reduced, and the water storage and fertilization of soil under environmental conditions of hill wastelands are achieved.

Description

technical field [0001] The invention relates to the technical field of soil water storage and fertilization on hilly and barren slopes, in particular to a compound material for rapid water storage and fertilization of hilly soil and a preparation method thereof. Background technique [0002] The hilly and mountainous areas of Jiangsu Province are mainly distributed in the northern part of the provincial border with Shandong Province, the western and southern part of the provincial borders adjacent to Anhui and Zhejiang Provinces, and extend to the hilly belt along Taihu Lake. The total area of ​​hilly and mountainous areas in the province is about 1.56 million hm 2 , accounting for 15% of the total area of ​​the province. The developed and utilized area is 131,000 hm 2 , there is still a large amount of undeveloped land, the utilization rate of land resources is still very low, and economic development is still relatively lagging behind. At the same time, the soil erosion...
