Alfalfa herb cultivation drought-resisting medium

Abstract

The invention discloses an alfalfa herb cultivation drought-resisting medium which is prepared from sandy soil, weathered coal, polysaccharide polypeptide biotic potassium, gamma-polyglutamic acid, degradable high water absorbing fibers, photosynthetic induction factors, mushroom leftovers and graft modified soybean proteins. The disease resistance and the stress resistance of alfalfa herbs can beenhanced, the alfalfa herbs can still keep healthy plant phenotypes under drought stress, the water retention capacity of the periphery of an alfalfa herb rhizosphere is enhanced, and the alfalfa herbs have high biomass and overground water content.

Description

technical field [0001] The invention relates to the field of forage planting, in particular to a drought-resistant substrate for cultivating alfalfa. Background technique [0002] Alfalfa is a perennial leguminous forage widely cultivated in semi-arid areas in my country. It has the characteristics of high yield, high quality and strong adaptability. , the phenomenon of soil desiccation generally occurs, leading to a gradual slowdown of alfalfa production and a continuous decline in grass yield, resulting in the degradation of alfalfa meadows, obstacles to the supply of animal feed, and restricting the development of grass and animal husbandry. [0003] Although the screening of drought-resistant alfalfa varieties has become an important way to improve the drought-resistant ability of alfalfa, the well-developed root system is often used as a main screening index for the drought-resistant ability of alfalfa. However, a well-developed root system will inevitably further enhan...

Problems solved by technology

However, a well-developed root system will inevitably further enhance the water consumption of alfalfa, aggravate soil drought, and further cause soil moisture and ecological environment problems.
