Abstract

The invention provides a bagasse-based water retaining agent. The bagasse-based water retaining agent comprises, by weight, 60-100 parts of bagasse, 10-20 parts of waste silk, 10-20 parts of bagasse biochar, 5-10 parts of bentonite, 10-20 parts of sludge, 50-80 parts of potassium acrylate, 0.1-3 parts of a crosslinking agent, 0.1-2 parts of an initiator and 1-5 parts of a polymerization agent. Theinvention also discloses a preparation method of the bagasse-based water retaining agent. The bagasse-based water retaining agent can significantly reduce the moisture loss of soil, has excellent water storage and water retention properties, can be degraded, and can improve the soil structure and provide necessary fertilizers and trace elements for plant growth after being degraded.

Description

technical field [0001] The invention relates to the field of planting agricultural and forestry crops, in particular to a bagasse-based water-retaining agent 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, the utilization rate of agricultural water resources should be improved. The implementation of water-saving and drought-resistant technology is an important way for the sustainable development of agriculture in our country. In my country, arid and semi-arid areas account for more than 50% of the country's land area, but the water holding capacity of the soil is low, and it is easy to evaporate, and the utilization of water itself is low. Therefore, the drought problem has increasingly become a problem tha...
