Method for preparing solid drought-resistant water-retaining nutrient solution

Abstract

The invention discloses a method for preparing solid drought-resistant water-retaining nutrient solution. The solid drought-resistant water-preserving nutrient solution is prepared by absorbing prepared nutrient solution through gel and dry-powder water-retaining agent produced by Plant Drought-resistant Water-retaining Agent Factory in Fusui County of Guangxi Province. The solid drought-resistant water-retaining nutrient solution is applied to the peripheries of roots of plants, and releases water for the plants and nutrient solution required by the growth of the plants during drought. After artificial irrigation or rainwater, the solid drought-resistant water-retaining nutrient solution can absorb and store excessive water, and releases water for the plants during drought, so that steady high yield of the plants can be achieved in the environment.

Description

technical field [0001] The invention relates to a preparation method of a solid drought-resistant and water-retaining nutrient solution, in particular to a preparation method of a solid drought-resistant and water-retaining nutrient solution capable of retaining water and resisting drought and releasing nutrients. Background technique [0002] Patent No. 200710188555.3 discloses a solid water and its preparation method. The process is to add an appropriate amount of gellan gum, xanthan gum and preservatives to ordinary water after heating, and cool naturally at room temperature to obtain solid water. The invention is easy to store and carry at normal temperature, is not easy to leak, and is suitable for daily water supply in arid areas and slow-release water supply for crops. But this invention process is complicated, and the product belongs to one-time use, without repeated drought resistance and water retention function, and has no market advantage; the patent No. 00105783...
