水稻两段式育苗技术及改进措施

The Technology and Improved Countermeasure on Rice Two-stages Seeding

为保证水稻晚熟品种能正常成熟,进行了两段式育苗技术研究。即在温室或室内或大棚内播种,当秧苗长到一定高度时再移入大棚苗床上继续育苗。指出了这种育苗的技术优势:秧龄可增加25～30d,带蘖率可达100%,增产21%,增收1800～2600元/hm2。为便于推广,在播种环节和第一次移栽技术上做了进一步改进。

In order to make the late variety grow normally,a research o n rice two-stages seeding was made,which is sowing seeds indoor or in green ho use and transplanting into film-house when the young plants grow to a certain h eight.Point out this technology can make the seedlings' age prolong25～30 d,the rate of having tillerings reach100%,the yield be increased21%,th e income be raised1800～2600yuan/hm 2 .In addition,more improvement was made to seed and transplant in techniq ue for its spreading.
