Sago is an annual herbaceous plant of the genus Agriophyllum of Chenopodiaceae (Chenopodiaceae), widely distributed in northern desert regions of China, is a pioneer plant of a moving dune, and is also an important wild economic plant and a sand fixing plant in the regions. In desert and desert grassland areas, sand rice is also an important plant for feeding.
The semen Sago is rich in crude protein, amino acids and various mineral elements, and is a natural functional green food. In recent years, the demand of the sandy rice market is increased sharply, and the large-scale harvesting of wild sandy rice by people obviously causes the problem of regional desertification that the self-recovery and the exploitation and utilization of sandy rice resources are obviously unbalanced, the population scale and the distribution region are rapidly reduced, the natural updating is low, and the regional desertification problem is aggravated.
The sandy rice has wide development prospect, and the edible sandy rice has great practical significance for improving the nutritional status of human beings, promoting health, relieving grain crisis and protein deficiency, and effectively promoting the coordinated development of regional ecological benefit, economic benefit and social benefit. Therefore, the urgent need for artificial planting to meet the market demand is a focus problem which needs to be solved at present. The only propagation mode of the sand rice is seed propagation, the sand rice is propagated on dry and high-temperature sand land, the natural germination rate is low, the reason is closely related to the harsh habitat, and the deep dormancy of the sand rice seeds is also an important factor of low germination rate.
Therefore, the problems that the artificial cultivation of the sand rice or the development of natural sand rice population is realized, the dormancy of the sand rice seeds is broken, and the germination rate and the emergence rate of the sand rice seeds are improved are needed to be solved. At home and abroad, a lot of studies on the germination of the sand rice seeds exist, but a method for quickly improving the emergence rate of the sand rice seeds and shortening the emergence period has not been reported so far.
