Problems solved by technology

[0003] Edible sunflower is one of the main economic crops in my country. It is mainly distributed at 23°-50° north latitude. Most of these areas are arid and the soil has high saline-alkali content. Drought and saline-alkali stress can damage crops in many ways, including ion poisoning , osmotic stress, the breakdown of intracellular ion balance, etc., causing material and energy metabolism disorders of crops, affecting the normal growth of crops, resulting in a significant decline in crop quality and yield
Seed germination is the initial stage of edible sunflower production. This important process is easily affected by external environmental factors. Under drought and saline-alkali stress, the activity of hydrolytic enzymes in seeds is significantly inhibited, and the energy and material supply required for germination is insufficient, resulting in The seed germination rate is low, which affects the further growth and development of edible sunflower, and seriously interferes with the normal sowing and production of field
There is no report about how to improve the germination rate of edible sunflower seeds in arid saline-alkali land at present, so it is urgent to propose a method for improving the germination rate of edible sunflower seeds in arid saline-alkali land, to improve the output of edible sunflower, thereby increasing the farmers' income in arid saline-alkali areas economic profit

Abstract

The invention provides a method for increasing the germination rate of edible sunflower seeds in arid saline-alkali soil, belonging to the field of commercial crop cultivation. The seeds are respectively soaked into a mixed solution of NaHCO3 and NaCl and a mixed solution of choline chloride and humic acid, so that the germination of the seeds is promoted, the harm, caused by the arid saline-alkali soil, to the seeds is relieved, the resistance of the seeds is improved, the speed of seed germination is accelerated, the uniformity of the seed germination is improved, and the germination rate of the seeds is further increased; after the method is used for treating the seeds, the germination rate of the seeds in an arid saline-alkali field reaches 92.4%, and the germination rate of the edible sunflower seeds is greatly improved. Furthermore, the method is simple to operate, and can be widely applied to seed pretreatment before seeding in the arid saline-alkali soil; the method provides an important reference for solving the problem of difficult seeding of the arid saline-alkali soil areas.

Description

technical field [0001] The invention belongs to the field of economic crop cultivation, in particular to a method for increasing the germination rate of edible sunflower seeds in arid saline-alkali land. Background technique [0002] Sunflower belongs to Compositae and Helianthus genus crops. Its seeds are rich in linoleic acid, oleic acid and a small amount of sterols (sterols), VE, phospholipids, vegetable waxes and carotenoids and other non-saponifiable substances necessary for the human body, which can lower cholesterol. and the prevention of cardiovascular disease. [0003] Edible sunflower is one of the main economic crops in my country. It is mainly distributed at 23°-50° north latitude. Most of these areas are arid and the soil has high saline-alkali content. Drought and saline-alkali stress can damage crops in many ways, including ion poisoning , osmotic stress, the breakdown of intracellular ion balance, etc., cause the material and energy metabolism of crops to be...
