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
The present invention relates to seed-pelleting technology, specifically, relate to a kind of grass seed pill metallization processes.
Background technology
Seed-pelleting packaging technique; it is the agricultural high-tech that adapts to meticulous sowing needs growing up on seed film packaging technique basis; can make the shape of the seed of some crop by irregular, the small spherula (comprising positive circle, ellipse, oblateness etc.) that transfers big or small homogeneous, regular shape to, so that the process technology of artificial and mechanization precision drilling.Seed pill clothing technological merit is to improve sowing effect, can make those crops that are not suitable for mechanical planting realize precision drilling, also can realize and broadcast front plant protection, and sick worm is double to be controlled, and promotes plant growth, improves and strengthen the resistance of seed.
At present, the obducens type of skill has four classes substantially: 1, heavy pill, the i.e. large granulation of small-sized seed; 2, crust dressing, also claims thick film coating, forms smooth surface, seed that shape is consistent, makes seed be more suitable for the Precise sowing of pneumatic sower, and seed to increase quality few, save material; 3, fast-growing pill, first carries out vernalization to seed prior to seeding, then carries out pill; 4, flat pill, makes larger, heavier flat pill tiny seed, prevents from being blown away, the accuracy while improving air seeding and land after stability, guarantee seeding quality.Common seed-pelleting processing technology mainly contains rolling comminution granulation and drift granulation, and the main flow process of its seed Pelleting dressing comprises: seed cleaning → seed disinfection → seed with sticker soak → mix with seed coat agent → with filler stirring → Pelleting moulding → hot air drying behaviour → by techniques such as granularity sieving classification → quality inspection → computation weigh → seam bag, pack → warehouse-ins.
At present; the main pooled applications of seed pill clothing technology is at the seed of shape matching rule both at home and abroad; on cotton, beet, vegetables, flowers and grass seed (alfalfa); the application of obducens technology is also comparatively general; its pill process equipment has also been realized commercialization, automation, standardization, seriation, and existing forward is intelligent, become more meticulous, goodization future development.But still there are some problems, need further to solve, as few in the kind of pill pelleting seed application, for grass seed, the application of gramineous forage grass seed (elongated and flat class seed) pill seldom, and because gramineous forage grass shape of the seed is irregular, easily in process, destroyed; Some pill pelleting seed mechanism formula, water content etc. are unreasonable, and adaptability is poor, cannot guarantee germination rate; Processing equipment and technique fall behind, and granulating shape is undesirable, become graininess poor.
Summary of the invention
