Abstract

The invention relates to a kind of pelleted coating powder of Chinese pine seeds. The powder comprises the following components in parts by weight: 97.3-97.75 parts of bentonite raw ore powder, 2 parts of talcum powder, 0.05-0.2 part of aspirin, 0.2-0.5 part of potassium dihydrogen phosphate, 0.0005-0.001 part of kinetin (KT), 0.0001-0.0005 part of NAA. The pelleted coating powder uses bentonite raw ore powder as main powder; and the substances such as aspirin (acetylsalicylic acid), kinetin (KT), potassium dihydrogen phosphate and water retaining agent which can be used to promote seed germination, increase drought resistance and promote seedling growth, are added properly. After the coatings are pelleted, the volume and grain weight of the Chinese pine seeds can be increased, aerial sowing drifts can be reduced, the seeds can sprout in advance, the germination energy can be increased, the damages caused by birds, beasts and rats can be reduced and the seedling rate can be increased.

Description

technical field [0001] The invention relates to a pelletized coating powder of Chinese pine seeds, which belongs to the field of agricultural seed processing. Background technique [0002] Pinus tabulaeformis is the main tree species for aerial sowing, direct seeding afforestation or sowing seedlings in northern mountainous areas. However, the germination of Chinese pine seeds is relatively slow. From sowing to emergence, the seeds must be stored in unfavorable soil environments such as drought, high temperature, and windy for a considerable period of time, and are susceptible to damage from birds, animals and rats. Prolonged germination is very unfavorable to seedling formation of Pinus tabulaeformis, especially when aerial sowing afforestation or artificial direct seeding afforestation often leads to failure. The longer the seeds remain on the surface or in the soil, the less chance they will survive. During aerial sowing, the seeds will also drift with the wind and affec...
