Problems solved by technology

However, this method has many steps in the process, the operation process is complicated, and the environmental conditions are high, and the strength of the soil column is low, the water retention performance is poor, and the water supply is insufficient. It is only suitable for application in humid areas, and it is difficult to adapt to arid areas.
[0009] Although the above-mentioned patents help the root system of imported plants to grow long and deep, can promote plant germination and initial growth, and can reduce the withering and damage of seedlings caused by drying, thereby improving the survival rate of plants, some of them are caused by seed beds. Some ingredients contain chemical materials that are not easy to degrade, which will leave hidden dangers for ecological development after use; some artificially added fertilizers are easy to lose with rainfall, polluting groundwater; some have many ingredients, complicated production processes, and high construction costs
Moreover, the use process of the above patents is relatively complicated, and some even require more than ten steps, which causes inconvenience to the application and construction

Abstract

The invention relates to a plant cultivating substrate as well as a preparation method and application of the plant cultivating substrate. The plant cultivating substrate is prepared by taking polyaspartic acid water-absorbent resin as a binder, mixing sand and water, moulding and drying, is preferably a truncated cone with a longitudinal through hole formed at an axis, and can be matched with a plant cultivating medium containing polyaspartic acid fertilizer and a polyaspartic acid water-absorbent resin aquasorb for plant seed preservation and seedling cultivation. The plant cultivating substrate can effectively absorb and retain moisture, can supply moisture and nutritional elements which are necessary to plant growth in an uninterrupted way, so that a greening effect can be achieved and the balance of a local ecological environment and species is not destroyed; therefore, the plant cultivating substrate is particularly applicable to afforestation, barren hill greening and desertification control in arid areas.

Description

technical field [0001] The present invention relates to a plant cultivation substrate and its manufacture and application, in particular to a seed conservation and seedling cultivation substrate added with polyaspartic acid water-absorbing resin and its manufacturing and application method, especially a kind of substrate which is beneficial to arid and semi-arid conditions. The method of growing seedlings and fixing sand in the area. Background technique [0002] The expansion of land desertification and the raging sandstorms are global environmental problems facing mankind today, which seriously affect the normal production and life of human beings. In order to improve and protect the earth's environment, countries around the world have actively carried out research and prevention of desertification and sandstorms. The technologies used to prevent and control desertification and sandstorms mainly include physical sand fixation, chemical sand fixation, biological sand fixat...
