Abstract

The invention belongs to the field of seed processing and relates to a method for processing seeds by using a physical method, in particular to a method for injecting roegneria kamoji seeds by utilizing ion beams. The method comprises the following steps of: selecting dry roegneria kamoji seeds and controlling the water content to be 5-14 percent; putting the seeds on a plate of an ion beam injection device; and then, putting the plate in a target chamber to carry out low-energy nitrogen ion beam injection, wherein the injection dose of the low-energy nitrogen ion beams is 500-4,200 dose units, energy in the target chamber is 25 kilo electron volts, the flow magnitude of the nitrogen ion beams is 12 milliamperes, intermittent pulse injection is adopted, the pulse dose each time is 100-500, and the injection spacing interval each time is 20-30s, and the injection vacuum degree is 1.6*10<-2>-2.6*10<-2>. In the method, the germinating ability of the roegneria kamoji seeds is obviously improved, the seeds thrive in a seedling stage, and plants are strong; and the output of a single plant is increased, and the crude protein and the crude fat of the plants are both increased. The method can obviously improve the output and the quality of the roegneria kamoji and has higher application value.

Description

Technical field: [0001] The invention belongs to the field of grass seed processing, and furthermore, the invention relates to a method for treating forage grass seeds with a physical method, more specifically, a method for using ion beams to inject grass seeds to obtain high-quality seeds. technical background: [0002] Goose view grass is a perennial forage grass of the family of Gramineae. It has wide distribution and strong adaptability. It also has the characteristics of moisture resistance, scab resistance, multiple flowers and multiple grains. These excellent characteristics provide valuable resources for breeding of close relatives of the wheat family. genetic resources. However, as a forage grass with feeding value, the yield and quality of Goose View Grass needs to be improved. At present, my country mainly increases the yield of crops or pastures through fertilization. However, fertilization will increase its cost, pollute the environment and degrade the soil. ...
