Abstract

The invention discloses a water-retaining agent for bamboo willow in drought regions and relates to the technical field of fast-growing tree planting. The water-retaining agent is prepared from the following raw materials in parts by mass: 50-60 parts of plant starch, 40-45 parts of polyacrylic acid, 20-25 parts of carboxymethyl chitosan, 15-20 parts of montmorillonite, 15-20 parts of nano calcium carbonate, 12-15 parts of gelatin, 10-12 parts of calcium sulfate, 8-10 parts of white carbon black, 5-8 parts of urea, 5-8 parts of phosphorus pentoxide, 2-3 parts of benzoyl peroxide, 30-40 parts of isopropanol and 100-120 parts of water. The water-retaining agent is capable of improving the soil water absorptivity and suitable for the drought regions, and has the water absorption rate within the range from 400 to 450; besides, the water-retaining agent has the characteristics of non-toxicity and innocuousness and automatic degradation, does not cause pollution to plants and soil underground water and is high in safety.

Description

Technical field: [0001] The invention relates to the technical field of planting fast-growing trees, in particular to a water-retaining agent for planting bamboo willows in arid regions. Background technique: [0002] Bamboo willow, also known as fast-growing bamboo willow and American bamboo willow, is a rookie of the new generation of forest trees with multiple genetic germplasm genes through hybridization and selection of American willow, Korean willow, basket willow, and moso bamboo genes. It has superfast growth, resistance Strong, good material, high density and other characteristics, it is a high-quality super-fast-growing new energy tree species that needs to be developed urgently. In a short period of time from its birth to the present, it has been highly concerned by experts in the forestry industry and scientific research institutions, and even sought after by everyone who is eager to get rich quickly. [0003] In terms of energy conversion technology, Chinese re...
