PREPARATION METHOD FOR PLANT GROWTH AGENT FOR ECOLOGICAL WATER CONSERVATION, FERTILIZER SAVING AND YIELD PROMOTION

摘要

Disclosed is a method for preparing a plant growth agent for ecological water conservation, fertilizer saving and yield promotion. The content of each component of the growth agent in mass percentage is: 40-72 wt% of straw, 5-12 wt% of a polypropylene salt, 6-15 wt% of diatomaceous earth, 1-5 wt% of waste paper, 8-30 wt% of zeolite, 10-30 wt% of water, and 0.054-0.135 wt% of an additive. The growth agent is prepared by means of a microwave method. The growth agent, when applied to soil, can rapidly absorb and retain rainwater or irrigation water without permeation loss, thus ensuring a sufficient and slow release of water within the scope of the rhizosphere for a plant to use. Furthermore, the growth agent has the function of absorbing fertilizers such as nitrogen, phosphorus, and potassium and retaining same in the growth agent for the plant to use, thus greatly reducing nutrient loss and extending fertilizer efficiency. Abundant water and nutrients, as well as the additive, can not only improve the soil, but can also promote the rapid and healthy growth of the plant. In addition, the growth agent has a simple preparation process and a low cost, and is non-toxic and harmless.
