Embodiment 1-1

[0081] 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.

Embodiment 1-3

[0131] The difference between this embodiment and Example ① in Example 1 is that the crosslinking agent is a mixture of N, N-methylenebisacrylamide, glycerol or glutaraldehyde, wherein, N, N-methylene The mass ratio of bisacrylamide, glycerol or glutaraldehyde is 1:0.6:0.7, and other conditions remain unchanged. The performance test data of the compound material for rapid water storage and fertilization of the hilly soil obtained is shown in the following table 2-1:

[0133]

[0134] The hilly soil rapid water storage and fertilization compound materials in Example 1-1, Example 1-2 and Example 1-3 have the following technical advantages: reduce the loss of fertilizer and water caused by surface runoff in the rainy season on hilly slopes, and improve the soil's ability to absorb moisture. Absorption rate and water holding capacity, increase soil moisture in dry season; suitable for hilly areas with serious soil erosion, extremely barren soil, poor soil st...

Abstract

The invention discloses application of a hill soil quick water-storage and fertilizer-increasing compound material in crop planting. The application comprises the following steps: (a) carrying out scene investigation to determine an experimental demonstration land; (b) organizing an excavator to prepare the experimental demonstration land; (c) clearing the experimental demonstration land; (d) using a tractor rotary cultivator to carry out soil turnover and deep-ploughing soil pulverization on the experimental demonstration land; (e) carrying out cell division; (f) digging holes in cells and planting crops in the holes; (g) filling the holes with a mixture of soil and the hill soil quick water-storage and fertilizer-increasing compound material; and (h) carrying out water covering after carrying out field planting. According to the application, the absorption rate and water holding capacity of the soil for water can be improved, the soil moisture in a dry season is increased, the loss of fertilizers and water, caused by surface runoff in a rainy season, of hill slopes is reduced, and soil water storage and fertilizer increase can be realized under a hill wasteland environmental condition.

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 the application of a compound material for fast water storage and fertilization of hilly soil in crop planting. Background technique [0002] The hilly and mountainous areas of Jiangsu Province are mainly distributed in the northern part of the border with Shandong Province and the western and southern borders of 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 rate in the hilly areas of Jiangsu is...
