对１４ 个水稻恢复系密直播的部分性状进行了考查。密直播使１３ 个非感光型恢复系的播抽历期平均缩短２３．９ ｄ，而使其株间抽穗历期（最早抽穗株至最迟抽穗株历期）平均延长了４．５ ｄ，但对强感光型的福恢９６２ 作用不明显。密直播的这种效应在水稻育种中有一定的利用价值
Fourteen rice restore parts of the direct seeding were examined. The sowing duration of 13 non-photoperiod restorers was shortened by 23.9 d on average by direct sowing, prolonging the inter-strain heading duration (the earliest heading date to the latest heading date) by an average of 4.5 days, However, the role of strong sensitive Fu Hui 962 is not obvious. The effect of dense direct seeding has some value in rice breeding
