Germination and seed cultivation method of Sorghum bicolor(L.)Moench

Abstract

The invention discloses a germination and seed cultivation method of Sorghum bicolor(L.)Moench. The method comprises the following steps: picking seeds with full grains; airing for 2 to 3 days in the sun; soaking the seeds by using a copper sulfate solution; cleaning the soaked seeds with water; soaking the seeds by using a budilizer after the seeds are soaked with the water of 45 DEG C; germinating at constant temperature in a germination box and then taking out the seeds; drying the seeds in the shade and sowing. The invention aims to provide the germination and seed cultivation method of Sorghum bicolor(L.)Moench. By using the budilizer, germination of the seeds is accelerated, and main components of the budilizer are composed of plant growth regulators, nutrient elements and osmoprotectants; dormancy of the seeds can be broken through, and the activity of the seeds is enhanced; moreover, under an effect of the budilizer, the growth of embryos and the activity of hydrogen peroxidase are both improved, so that a good effect of accelerating the germination of the seeds is achieved.

Description

technical field [0001] The invention belongs to the field of agricultural science and technology, and in particular relates to a method for accelerating germination and breeding of sorghum. Background technique [0002] Sorghum is the fourth largest food crop after wheat, rice and corn in the world, and it is also an important dry food crop in my country. Because of its strong resistance to drought, waterlogging, and barrenness, it is widely distributed in arid, semi-arid, low-lying and easy-to-waterlog areas. Sorghum has many different uses, including edible, feed, and food processing. Sorghum is the main miscellaneous grain crop in the north, but it tends to be green and late-maturing in years of spring flood or autumn frost and drought. Therefore, we need to accelerate germination and promote early maturity of sorghum to achieve the effect of increasing production.

Problems solved by technology

[0003] In the patent CN1557118, a kind of germination agent and germination method thereof for Liaodong Aralia and Aralia changbai seeds of Araliaceae are provided, wherein the germination agent used is a mixture of gibberellin and naphthaleneacetic acid, and gibberellin accounts for the total amount of germination agent. 60%-90% of the weight, naphthaleneacetic acid accounts for 10%-40%. Using the compound formula of gibberellin and naphthaleneacetic acid, it solves the problem of low germination rate and emergence rate of the rare wild vegetables of Araliaceae Liaodong Aralia and Changbai Aralia Problems such as waste of resources and shortage of resources

It is well known that gibberellin and naphthalene acetic acid can regulate plant growth, break dormancy, promote germination, and promote rooting, but only using these two materials as germination agents cannot achieve very good results
