Comparison Study on Optimum Cultivars and Cultivation Methods of Double Cropping Rice in Cold Water Paddy Field
摘要
Abstract
To select optimum double cropping rice cultivars and high-yielding cultivation methods adapted to the cold water paddy fields, the field experiments were conducted in Ningxiang county, Yongxing county and Taoyuan county of Hunan province in the early and late season in 2009. The results were showed as follows:(1) There were significant differences in yield and its components among cultivars, and the highest averaged yield in 3 locations reached to 5. 68 t/hm2 ( Luliangyou-996) and 5. 61 t/hm2(Tianyouhuazhan) in early and late season respectively. (2) Significant differences in yield existed a-mong different cultivation methods. The highest average yield in 3 locations under ridge cultivation method was highest, which reached 5. 52 t/hm2 in early season and 5. 81 t/hm2 in late season, and that under traditional cultivation method was the lowest yield, which were 4. 75 t/hm2 and 5. 25 t/hm2 in early and late season respectively. So it is advantageous to gain high yield in cold water paddy field by combination of optimum cultivars and ridge cultivation method.关键词
