草类种子包衣技术现状综述

Review of Grass Seeds Coating Technology

种子包衣是草种改良的重要途径,通过丸粒化可增加种子的流动性,提高机械化播种性能;包衣中添加植物生长调节剂等,可提高种子活力,促进发芽和提高成苗整齐度;添加杀虫杀菌剂,可防治苗期病虫害,提高幼苗存活率;保水剂及其他活性物质可提高包衣种子抗逆性。本文简述了种子常用的包衣材料,并对禾本科、豆科和菊科共20多种草类种子包衣的研究现状进行了概述。

Seed coating is one of the most important methods to improve grass seed quality.It increases mobility of pelleted seeds for good performance in mechanized sowing.Plant growth regulators added to seed coating material or pretreated with it would improve seed vigor so as to improve germination rate and germination percentage.Pesticide as an active ingredient would prevention pests and diseases in the seedling stage for higher seedling survival rate.Aquasorb and other active ingredients would improve stress resistance of grass.This context introduced several commonly used coating materials,and summarized the advances in coating researches on over twenty different kinds of grass seeds that belong to Gramineae,Legume and Asteraceae plant.
