前言水稻种子同其它农作物一样,为获得种子的田间播种价值,应提倡精量播种,达到壮秧(插秧田)、健苗(直播田),实现增产的目的。但是黑龙江省水稻生产,长期以来沿用密播密插,进行密植栽培,播种量普遍偏大,种子质量粗糙,已给生产上带来了不良后果。早已引起人们的注视。近几年来,随着各地稻作技术的不断改革,一些地方应用旱育苗稀播稀植,大大减少了播种数量,提高了播种质量,加上其它增产措施,收到省工、省成本、增产显著的良好效果。有些直播田,由于不断改

Introduction Rice seeds, like other crops, should be used for precision seed sowing to achieve strong seedling (seedling transplanting) and Jianmiao (direct seeding) so as to achieve the purpose of increasing production. However, the rice production in Heilongjiang Province has long been used for the close planting and close planting. The planting density is generally large and the seed quality is rough, which has brought adverse consequences to the production. Already attracted people’s attention. In recent years, with the constant reform of rice technology in various places, some places use dry planting seedlings to sow thinning and thinning, greatly reducing the number of sowing, improving sowing quality, adding other stimulation measures, receiving provincial labor, provincial costs and increasing output Significantly good results. Some live Tian, ​​due to continuous change
