- 摘要:
- 龙粳20具有早熟、优质、高产、抗病、耐寒等特点，2007年1月通过黑龙江省审定并推广，同年3月获得国家新品种保护权。2008年推广面积17.53 万hm2，2009年推广面积14.61 万hm2，成为黑龙江省第三积温带主栽品种。2008年列为农业科技成果转化资金项目，2009年列为第3积温带早熟组对照品种。针对龙粳20出现早穗等不足，提出配套关键栽培技术。
- Abstract:
- Longjing 20 was extended through the Heilongjiang Province in January 2007.It have characteristic with early-maturing，high-quality，high yield，disease resistance，cold resistance etc.It won the State of New Varieties of protection in March 2007.There were promotive area of 0.1753 millions hm2 in 2008 and 0.1461 millions hm2 in 2009，so it has become main variety in the third accumulated temperature in Heilongjiang Province.It was classified as an agricultural science and technology achievements into capital projects and as a Contrastive variety of early-maturing group in the third accumulated temperature in 2009.In accordance with shortage of earlier ear and so on， this text put forward supporting the key cultivative techniques of Longjing 20.
