Abstract

The invention provides a method for enhancing stress resistance of alfalfa. The method comprises the following steps of (1) soaking the seeds of alfalfa in a mixed solution of hymexazol and glycine; (2) air-drying the soaked seeds in shady place and then sowing the dried seeds into artificial soil, which is composed of milk powder, chitosan, bentonite, dicyandiamide, potassium chloride, S-abscisicacid and agritol; (3) after the seeds grow rhizomes, transplanting the plants into natural fields, and injecting a mixed solution of bacillus subtilis and deuterium-depleted water into the stem partsof the transplanted plants; (4) 60-80 days later, spraying a mixed solution of gibberellin, ciclosporin, phosphate solubilizing bacteria, melatonin and multi-vitamins onto the leaves and the soil ofthe plants. The method for enhancing the stress resistance of the alfalfa has the advantage that the artificially cultivated alfalfa plants can enhance the stress resistance after being transplanted to planting environments such as poor soil and saline-alkali soil and further can achieve mass production.

Description

technical field

[0001] The technical field of agricultural production of the present invention is specifically a method for enhancing the stress resistance of alfalfa. Background technique

[0002] Alfalfa (Medicago Sataiva L) is one of the fine forage grasses with the longest cultivation history in the world, and it is also the largest cultivated forage grass in my country. Since the 1990s, with the rise of the alfalfa industry, the requirements for alfalfa varieties have been continuously improved, from stress resistance (cold resistance, drought resistance, salt-alkali tolerance, etc.), yield to quality more and more comprehensive. The research on comprehensive traits has also continued to deepen from botanical traits, economic traits, stress resistance traits and nutritional status. In my country, the cultivation of alfalfa is mainly in barren land without irrigation conditions, saline-alkali land and other natural conditions that are not suitable for planting main crop...
