Embodiment Construction

[0017] specific implementation plan

[0018] The present invention will be described in further detail below in conjunction with the following specific embodiments:

[0019] Weigh the following raw materials in parts by weight (kg): cornstarch 65, acrylamide 55, biogas residue 14, ammonium persulfate 0.3, N, N'-methylenebisacrylamide 0.5, vermicompost 20, acrylic acid 65, Vinegar grains 9, EM bacterial agent 2;

[0020] The specific steps of the preparation of the water-retaining matrix are as follows:

[0021] (1) Put the cornstarch in water 1 times its mass, boil and heat for 35 minutes, set aside;

[0022] (2) When the material obtained in step 1 is cooled to room temperature, add acrylic acid and acrylamide, stir well, add sodium hydroxide to neutralize, then add ammonium persulfate, N,N'-methylenebisacrylamide, and heat the reaction system React at 90°C for 2 hours;

[0023] (3) Dry the material obtained in step 2 at 100° C., put it in a pulverizer and pass it through...

Abstract

The present invention discloses an easily degradable particle type water retention matrix and a preparation method thereof, the easily degradable particle type water retention matrix is prepared from the following raw materials by weight: 55-75 parts of corn starch, 50-60 parts of acrylamide, 12-15 parts of biogas residue, 0.2-0.4 part of ammonium persulfate, 0.4-0.5 part of N, N'-methylene-bis-acrylamide, 18-22 parts of vermicompost, 60-70 parts of acrylic acid, 8-10 parts of vinegar residue, and 2-3 parts of EM microbial agent; the easily degradable particle type water retention matrix is prepared from the matrix materials which are all degradable, after use, rainfall and irrigation absorbing capacity and absorption rate of soil can be significantly improved, surface runoff can be reduced, while the increase of time, the water retention matrix may be gradually degraded into soluble nitrogen, phosphorus and other nutrients which can be absorbed and utilized by plants, soil organic matter content can be improved, soil beneficial microbial activity can be increased, and a favorable environment for the growth of the plants is created.

Description

technical field [0001] The invention relates to the technical field of a water-retaining matrix, in particular to an easily degradable granular water-retaining matrix and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and agricultural water accounts for more than 80% of my country's total water consumption. The shortage of water resources is the primary reason restricting the development of my country's agriculture. Therefore, improving the utilization efficiency of agricultural water resources and implementing water-saving and drought-resistant technologies are important ways for the sustainable development of agriculture in my country. Among them, as an agricultural water-saving technology, the water-retaining matrix has a wide range of raw materials, superior performance, simple operation and low cost, and has no side effects on the environment, so it has broad development prospects. However, there are few specific...
