Abstract

The invention discloses a Chinese red pine seed coating agent, a preparation method therefor and an application of the Chinese red pine seed coating agent. The coating agent comprises 1-25 parts of drought resisting and water retention agent, 2-8 parts of adhesive, 1-25 parts of soil improvement agent, 20-40 parts of humus soil, 0.005-0.05 part of growth regulator and 40-100 parts of water. The preparation method comprises the steps: mixing the drought resisting and water retention agent, the adhesive, the soil improvement agent, the humus soil and the growth regulator, and then, carrying outuniform stirring; and then, pouring water with stirring until the mixture is viscous, and then, carrying out standing until the mixture is coagulated. The coating agent disclosed by the invention canbe applied to coating of Chinese red pine seeds and has the advantage of improving the germination rate and drought resistance of the Chinese red pine seeds; and furthermore, the preparation method disclosed by the invention has the advantage of simply and efficiently preparing the coating agent and carrying out Chinese red pine seed coating.

Description

technical field [0001] The invention relates to the technical field of pine pine seeds, more specifically, it relates to a coating agent for pine pine seeds and its preparation method and application. Background technique [0002] Seed coating is a technology that uses a film-forming agent or adhesive to adhere the coating agent to the surface of the seed to promote seed germination and seedling growth. Through seed coating, the seeds can quickly absorb water and swell after sowing, and quickly absorb various active ingredients in the coating agent, thereby increasing the germination rate of seeds, enhancing the resistance of seedlings, preventing pests and diseases, and promoting the growth of seedlings. The research on seed coating began in the mid-1980s, but there has been more research on crop seed coating agents, but little research on forest tree seed coating agents. [0003] Masson pine (Pinus massoniana) is widely distributed in the subtropical regions of my country...
