| 摘要: |
| 对陆稻新品系秦爱的抗旱性进行了田间鉴定。在1980、1981两年干旱比较严重的条件下,秦爱在主穗的结实粒数、结实率、主穗粒重等方面,都比石狞、太阳一号、合江19优越,表现了较好的抗旱性。旱种时,秦爱生长较繁茂,根系发达,属极早熟大穗少蘖类型,华北地区,可在旱地与小麦连作,有广泛发展的可能。 |

| Abstract: |
| A new upland rice line Qin-ai raised by our group was tested in an upland plot without irrigation in comparism with two lowland rice varieties in 1980 and four others in 1981.Seeds were sown five times in June and July at intervals of 10 days.Precipitation during the growth duratin after above-mentioned planting dates amounted from 170.4mm to 245.0mm in 1980 and from 310.4mm to 350.2mm in 1981. Compared with the control plants in flooded pots all entries in up- land plots reduced their height,delayed their ... |
