| 摘 要： | 在清流县开展了“嘉优99”机收再生稻栽培的可行性试验。结果表明，嘉优99适宜作机收再生稻栽培，表现碾压后再生成穗能力强；3种不同机收留桩高度，其产量高低依次是留桩30cm〉15cm〉8cm处理，表现高留桩成穗率高，低留桩再生苗成穗率降低，从而影响产量；收割机碾压区再生苗的抽穗、成熟时间迟于未碾压区10d左右，通过增施氮肥可以调近两者再生季成熟期，方便收获和减少落粒谷损失。

| Abstract: | The feasibility of machine-harvesting ratoon rice cultivation for Jiayou 99 was conducted at Qingliu county. The results showed that Jiayou 99 was suitable for machine-harvesting ratoon rice cultivation, and exhibited strong effective ratooning tiller ability after rolling. For 3 different stubble heights after machine-harvesting, grain yield in the second crop ranked the highest of 30cm stubble height, the second 15cm, and the third 8cm, exhibiting high effective panicle rate of high stubble height and low effective panicle rate of low stubble height, which influenced yield. The heading and ripening stages of ratooning seedlings in the rolled zone by harvester were 10d later than no rolling zone, but their ripening differences in the second crop can be adjusted by increasing N fertilizer application rate, which will help to harvest conveniently and reduce loss of shattering grain. |
