Sorghum seed initiator under saline-alkali stress

Abstract

The invention relates to a sorghum seed initiator under saline-alkali stress. By using distilled water as a carrier, the sorghum seed initiator is prepared from 5-8 ppm of SA (salicylic acid), 800-1000 ppm of PEG (polyethyleneglycol), 10-22 ppm of GA4 (gibberellin), 100-120 ppm of ethrel and 80-100 ppm of Bavistin.

Description

Technical field [0001] The invention relates to a seed treatment agent, in particular to a sorghum seed initiator under salt-alkali stress. Background technique [0002] Soil salinization is a major environmental factor that restricts crop growth and reduces crop yields; the total area of ​​various saline-alkali land in my country is about 100 million hm 2 Moreover, soil salinization and secondary salinization continue to increase every year, threatening the sustainable development of agricultural production; therefore, in the context of increasing population and declining arable land, we should fully understand the salt tolerance mechanism of plants and develop and utilize them Salt-tolerant plant resources have a great impact on the quality of agricultural seeds and the yield and quality of crops. In particular, seeds with high viability and vitality are the basic development, food security, ecological environment, etc. for the production of high-quality crops required by modern...

Problems solved by technology

[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 later yield. How to improve the salt tolerance of sorghum seedlings is the key problem that should be solved first when planting sorghum in saline land; the concept of "priming" was proposed by Heydecker et al. in 1973 It was proposed in 1999 to describe the water absorption process of seeds under controlled conditions; seed priming technology is proposed based on the biological mechanism of seed germination, the purpose is to promote seed germination, and improve the stability rate of germination time and germination uniform rate, reduce The standard deviation of germination time can improve the resistance and quality of seedlings, improve the nutritional status, and trigger the main purpose through osmotic regulation, temperature regulation, gas regulation and hormone regulation;
