Screening and Matching Techniques of Rice Direct-seeding in Cold RegionⅡ .Variety Screening for Direct-seeding Japonica Rice
摘要
Abstract
In a pot trial ,analysis on j aponica rice emergence rate under the water and dry direct seeding and the high and low temperature ,selected optimal direct‐seeding varieties .The test results showed that six varieties had good emergence rate including Longjing 29 ,Longjing 31 ,Longjing 39 ,Suijing 4 ,Lorgyu 1 and Longyu 2 in water planting field ;eight varieties in dry planting had good emergence rate induding Longjing 14 ,Longjing 20 , Longjing 26 ,Longjing 27 ,Longjing 36 ,Longjing 39 ,Longjing 42 and Long 1356 .In low temperature ,emergence rate of water planting field was significant better than of dry planting ,the same variety emergence of dry planting in the high temperature was higher than of the low temperature ,dry direct seeding of the yield was 7 500 .0 kg·hm‐2 .关键词
