Osmoregulation initiation method of sorghum seeds under saline-alkali stress

Abstract

The invention provides an osmoregulation initiation method of sorghum seeds under saline-alkali stress. The osmoregulation initiation method comprises the following steps of: preparing initiating agents a and b of the seeds; in a cleaning ware, filling warm water with the temperature of 55-57 DEG C and setting the water amount to be 5 times of the volume of the seeds, immersing the seeds into the warm water, continuously stirring, stopping stirring when the water temperature falls to 30 DEG C, and filtering water; diluting the initiating agent a and b of the seeds by 500 times, pouring the initiating agent a of the seeds into the ware, soaking for 30 minutes, then pouring the initiating agent b of the seeds, stirring, soaking for 16-20 hours, wherein the amounts of the initiating agents a and b of the seeds are same and are twice of the volume of the seeds and the temperature is set to be 25-28 DEG C; and filtering the seeds, bleaching for once to twice with clean water, absorbing the moisture, putting the seeds into a special oven for back drying, setting the temperature to be 40 DEG C, controlling the water content in back drying to be 8.0%+ / -0.2%, and sowing or storing the seeds immediately.

Description

technical field [0001] The invention relates to a seed treatment method, in particular to an osmotic regulation initiation method of sorghum seeds under saline-alkali stress. Background technique [0002] Soil salinization is a major environmental factor that restricts crop growth and reduces crop yield; the total area of ​​various saline-alkali lands in my country is about 100 million hm 2 , and soil salinization and secondary salinization continue to increase every year, threatening the sustainable development of agricultural production; Salt-tolerant plant resources have a great influence on the quality of agricultural seeds on the yield and quality of crops, especially seeds with high vigor and vitality are the basis for the production of high-quality crops required by modern supermarkets, food security, ecological environment, etc. It is of great significance; sorghum is one of the crops with strong salt tolerance, but sorghum is very sensitive to salt stress at the ge...

[0002] Soil salinization is a major environmental factor that restricts crop growth and reduces crop yield; the total area of ​​various saline-alkali lands in my country is about 100 million hm 2 , and soil salinization and secondary salinization continue to increase every year, threatening the sustainable development of agricultural production; Salt-tolerant plant resources have a great influence on the quality of agricultural seeds on the yield and quality of crops, especially seeds with high vigor and vitality are the basis for the production of high-quality crops required by modern supermarkets, food security, ecological environment, etc. It is of great significance; sorghum is one of the crops with strong salt tolerance, but sorghum is very sensitive to salt stress at the germination and seedling stages, and its salt tolerance is poor, resulting in poor emergence and low seedling rate of sorghum planted in saline land, making it difficult to maintain seedlings , resulting in lack of seedlings and broken ridges, thereby affecting the yield in the later period. How to improve the salt tolerance of sorghum seedlings is the key problem that should be solved first when planting sorghum in saline land;
