Method for improving activity of forage grass seeds

Abstract

The invention discloses a method for improving the activity of forage grass seeds. The method comprises the following steps of (1) pretreating seeds to obtain pretreated seeds; and (2) putting the pretreated seeds into an ion implanter, injecting a low-energy nitrogen ion beam in an intermittent pulse injection mode with a heat effect and / or without a heat effect, and controlling the total injection dose of low-energy nitrogen to be (3000-8000) * 2.6 * 10<13> ions / cm<2>, the energy to be 20-30keV and the size of the nitrogen ion beam to be 10-15mA. According to the method, the quality and yield of the seeds can be further improved by utilizing a low-energy nitrogen ion implantation technology and controlling the existence or absence of the heat effect.

Description

technical field

[0001] The invention relates to the technical field of forage planting, and more specifically relates to a method for improving the vigor of forage seeds. Background technique

[0002] There are many techniques for treating plant seeds with physical and chemical methods to improve seed vigor and achieve high yield. The traditional methods of treating seeds with chemical substances include plant growth regulator treatment, trace element fertilizer treatment and chemical agent treatment (Seed World, 2009.5, Seed treatment methods and applications, Li Guozhong, etc.), this method has been used in sterilization, disease prevention, Improving seed vigor and high yield has been widely used, but chemical treatment methods are likely to cause damage to the soil environment.

[0003] With the development of modern science and technology, the application of physical methods to treat crop seeds to make them high-yield and high-quality has been more and more used in agr...
