保护性耕作模式下精少量播种推广研究

Small Amount Sowing Promotion Research Under Conservation Tillage Mode

根据农作物播量大(特别是小麦)在实施保护性耕作技术中存在的突出问题,分析其原因,研究提出推广精少量播种技术的核心是减少播量。通过减少播量来减少基本苗数和群体量,提高成穗率、穗粒数和千粒质量,实现高产稳产。介绍了合理确定作物播量、播深的方法及数据。得出了扩大精少量播种应用区域和应用作物,加大精少量播种的试验研究和宣传培训力度,制定新的精少量播种作业技术规范、作业质量标准等技术文件的结论和建议。

According to the large amount of planting crops（particularly wheat） in the outstanding problems that exist in the implementation of conservation tillage technology, did analysis of the reason, to study and put forward the promotion of pure a small amount of planting technology core is to reduce the quantity. By reducing the sowing quantity to decrease the basic seedling number and group, to improve the earning rate, spike grain number and grain quality, to achieve high and stable yield. This paper introduced the reasonable amount of crop planting, sowing depth method and data, should expand the essence of a small amount of crops planting area and application, increase the fine experimental study of a small amount of planting and publicity efforts in training, to make a new essence of a small amount of planting operation specification, operation quality standard.
