Manufacturing method for salt-tolerant zoysia japonica pelleted seeds

Abstract

The invention discloses a manufacturing method for salt-tolerant zoysia japonica pelleted seeds, belonging to the technical field of seed pretreatment. The manufacturing method comprises the followingsteps: carrying out seed dressing on healthy naked seeds with ascorbic acid, wherein the mass ratio of the naked seeds to the ascorbic acid is 1 g: (0.35-1.4) mg, and the solution concentration of the ascorbic acid is 2-8 mmol.L<-1>; allowing zoysia japonica seeds to roll in a pelleting machine at a constant speed, alternately adding an adhesive and a powder, and carrying out uniform stirring until the adhesive and the powder are uniformly coated on the zoysia japonica seeds so as to obtain the salt-tolerant zoysia japonica pelleted seeds. According to the invention, the ascorbic acid is adopted for seed dressing of the zoysia japonica seeds, so the salt stress effect of the zoysia japonica seeds can be effectively relieved; the vitality of the seeds can be improved; a certain germinationaccelerating effect is achieved; and the purposes of promoting seed germination, seedling uniformizing and seedling strengthening are achieved; meanwhile, the zoysia japonica seeds processed by pelleting are increased in volume and weight and uniform in specification, so mechanical and precise seeding can be easily realized.

Description

technical field [0001] The invention belongs to the technical field of seed pretreatment, and in particular relates to a preparation method of salt-tolerant zoysia ball-coated seeds. Background technique [0002] Zoysia (Zoysia) belongs to the Poaceae (Gramineae) Chloridoideae (Chloridoideae), Zoysia japonica (Zoysia japonica) is a high-quality warm-season lawn grass with good stress resistance such as drought resistance and salt tolerance Alkali and trampling resistance, so it has great use value in landscaping and sports field lawn, mainly distributed in Africa, Asia and coastal areas of Australia. Liaodong Peninsula and Jiaozhou Peninsula are the areas with the most natural Zoysia grassland distribution in my country, mainly coastal saline-alkali land. Studies have shown that saline-alkali stress will reduce the number of emergence and coverage of Zoysia turfgrass, and prolong the time for lawn formation. [0003] As a major abiotic stress, salt stress affects most of th...

Problems solved by technology

Under salt stress, reactive oxygen species are mainly generated in organelles such as mitochondria and chloroplasts. Studies have shown that the increase of ROS will cause damage to proteins, membrane lipids, nucleic acids, etc., thereby hindering the normal metabolic activities of plants and affecting the normal growth and development of plants.

In the study of corn (Zea mays), rape (Brassica napus) and oats (Avena sativa), it was found that when the salt concentration reached a certain threshold, the germination potential and germination rate of seeds decreased, and the length of seedlings shortened, resulting in reduced seed vigor
