窄行距插秧机田间试验效果分析
Effects of Field Trial with Narrow Row Spacing Transplanter
摘要
Abstract
With the problem of whether it should reduce the row spacing of mechanized transplanting in southern China , especially for conventional rice in double cropping areas , by using the randomized block experiment design , two field tri-als of different row spacing with the same plant spacing and different row spacing with the same number of plants were conducted .The results showed that the yield of 25 cm row spacing was higher than that of 30 cm with 25 cm plant spacing , while the yield of 30cm row spacing was higher than that of 25cm with 18cm plant spacing .The yield of 30cm row spac-ing was higher no matter the plant number was 14000/667 m2 or 16000/667 m2 .Taking into account of different aspects of yield , economy , standardization etc ., transplanter with 25 cm row spacing can be used in specific regions , but transplan-ter with 30 cm row spacing is still the mainstream models .A wide range of changing the row spacing is not recommended .关键词
