Embodiment 1

[0014] The seeds of Huaidao 5, Wuyunjing 27 and Wuyujing 3 were treated with cold plasma. Firstly, the seeds are placed in a cold plasma seed treatment machine, and the seeds are treated with non-ionizing radiation for 20s under the treatment power of 100W, and the treatment medium is helium in a vacuum environment. The treated seeds are subjected to a germination test, which is carried out with reference to the National Crop Seed Inspection Regulations-Germination Test (GB / T 3543.4-1995). Statistical seed germination rate.

[0015] The rice and wheat production increase experiment was carried out in Yancheng Xinyang Farm of Jiangsu Agricultural Reclamation Group. The treated seeds were sown in the experimental field. Yield was measured at harvest.

[0016] The present invention can not only promote rice seed germination (Table 1), but also increase rice yield (Table 2). The invention can significantly increase the germination rate of rice seeds by 5.8%, 9.7% and 29.6% com...

Embodiment 2

[0022] Yannong 19 and Huaimai 22 wheat seeds were subjected to cold plasma treatment. First, the seeds were placed in a cold plasma seed treatment machine, and the seeds were treated with non-ionizing radiation for 17s at a treatment power of 80W. The treatment medium was helium in a vacuum environment. The treated seeds are subjected to a germination test, which is carried out with reference to the national crop seed inspection regulations-germination test (GB / T3543.4-1995). Statistical seed germination rate.

[0023] The rice and wheat production increase experiment was carried out in Yancheng Xinyang Farm of Jiangsu Agricultural Reclamation Group. The treated seeds were sown in the experimental field. Yield was measured at harvest.

[0024] The present invention can promote wheat seed germination (Table 3), and can increase wheat yield (Table 4). The invention can increase the germination rate of Yannong 19 and Huaimai 22 seeds by 6.2% and 7.0% compared with the control...

Embodiment 3

[0030] Zhongdou No. 40 soybean seeds were subjected to cold plasma treatment. First, the seeds were placed in a cold plasma seed treatment machine, and the seeds were treated with non-ionizing radiation for 18s at a treatment power of 90W, and the treatment medium was helium in a vacuum environment. The treated seeds are subjected to a germination test, which is carried out with reference to the national crop seed inspection regulations-germination test (GB / T3543.4-1995). Statistical seed germination rate and determination of seedling growth.

[0031] The present invention can effectively promote soybean seed germination (Table 5). Compared with the control, when the treatment power was 90W and the treatment time was 18s, the germination potential, germination rate, germination index and vigor index of soybean seeds were significantly increased by 9.5%, 9.5%, 14.8% and 63.3%, respectively.

[0032] Table 6 shows that the present invention can promote the growth of soybean se...

Abstract

A cold-plasma seed treatment method capable of promoting germination of seeds of grain and oil crops and increasing the yield of the grain and oil crops comprises steps as follows: the oil crops and rice wheat seeds are subjected to cold plasma treatment under the treatment conditions that helium is taken as a discharge medium, the treatment power is 60-140 W and the treatment time is 15-20 s. An HD-2N type glow discharge cold-plasma seed treating machine is used for nonionizing radiation treatment, good stimulation is generated on the seeds, seed coat permeability can be remarkably increased, hydrophily and water absorbing capacity of the seeds are enhanced, the katabolic metabolism capability of seed storage substances is further improved, and accordingly, seed germination and seedling growth are remarkably promoted.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency agriculture, and in particular relates to a cold plasma seed treatment method for promoting seed germination and increasing yield of grain and oil crops. Background technique [0002] Rice and wheat are the most important food crops in my country. Soybean, peanut and sesame are the main oil crops in my country. Although my country's grain and oil production ranks among the top in the world, its output per unit area is low, and the planting area is declining year by year. The production and supply of oil and grain cannot meet the consumption demand. Due to the characteristics of grain and oil seeds and unsuitable growth conditions, the germination rate of seeds will be reduced, the germination time will be prolonged, and the uniformity of germination will be reduced, which will eventually lead to a decrease in yield. Seed germination is an important stage in the growth history of plants, ...
