水稻一段超早栽培品种及移栽规格研究

对一段超早栽培进行品种及移栽规格试验研究,结果表明：品种要采用分蘖力较强、每穗粒数稍多（100粒左右）,结实率较高（85%以上）、千粒重达25~26 g左右的品种为宜;密度10~18穴/m2,产量差异不显著,移栽密度选择10穴/m2更为经济;每穴基本苗数取2~3株为宜。

Study on Cultivated Variety and Transplant Specification on Rice One-stage Ultraearly Seeding Nurturing

The cultivated variety and transplant specification on rice one-stage ultraearly seeding nurturing were re- searched and the result indicated that varieties should select higher tiller capability, more grains per panicle （about 100）, higher Rice kernel set（over 85%）, appropriate 1000-grain weight（25-26 g）. When the density was 10-18 hills/m2, it made no significant crop yield difference each others, the economic transplant density was l0 hills/m~ and appropriate basic seedlings was 2-3 hills/row.
