Grass seed pelleting process

Abstract

The invention provides a grass seed pelleting process. The grass seed pelleting process comprises the following steps: (1) mixing matrix components, and extruding to form a columnar particle matrix by using a pelleting extruder, wherein the diameter of the columnar particle matrix is smaller than 4mm, and the length of the columnar particle matrix is 5-15mm; (2) mixing grass seeds with the columnar particle matrix according to the proportion of (1-2) to (100-150); (3) extruding the grass seeds and the columnar particle matrix by using a double-roll extrusion pelleter for pelleting under the extrusion strength of 8Pa to form flat-spherical vegetation particles of which the diameter is 4-10mm. According to the grass seed pelleting process, the technical problems that the shape of gramineous grass seeds is irregular and the gramineous grass seeds are easily damaged in the preparation process are solved, the drift of the seeds can be effectively reduced, the landing stability of the seeds is improved, and the seeding accuracy and the seed germination rate are improved. The grass seed pelleting process is applicable to mechanical operation and is particularly applicable to northern droughty grassland regions.

Description

technical field [0001] The invention relates to seed pelletization technology, in particular to a pasture seed pelletization technology. Background technique [0002] Seed pellet coating technology is an agricultural high-tech developed on the basis of seed film coating technology to meet the needs of precision sowing. It can change the shape of certain crop seeds from irregular and tiny to uniform in size, Small spheres with regular shape (including perfect circle, ellipse, flat circle, etc.) are suitable for the processing technology of manual and mechanized precision seeding. The advantage of the seed pellet coating technology is that it can improve the sowing effect, realize precision sowing of those crops that are not suitable for mechanical sowing, and also realize pre-sowing plant protection, both disease and pest control, promote crop growth, and improve and enhance the stress resistance of seeds. [0003] At present, there are basically four types of pellet coating...

AI Technical Summary

Problems solved by technology

But there are still some problems that need to be further solved, such as the few types of pelleted seeds, for forage seeds, the application of gramineous forage seeds (slender and flat seeds) pelleting is seldom, and due to the Forage seeds have irregular shapes and are easily damaged during processing; some pelleted seeds have unreasonable formulations, water content, etc., poor adaptability, and cannot guarantee the germination rate; the processing machinery and technology are backward, and the shape of the pellets is not ideal , poor granulation
