不同水稻土对双季稻光合特性及产量的影响
Effect of different paddy soils on photosynthetic characteristics and yield of double cropping rice
摘要
Abstract
Under the mode of potato-double cropping rice, Xiangzaoxian45 and Fengyuangyou299 were used as early rice and late rice respectively, six soil treatments (mashing mud, stucco, purple mud, red yellow mud, yellow mud and river sand mud) were conducted to study the effects of different paddy soils on photosynthetic characteristics and yield of double cropping rice. The results showed that the SPAD value, net photosynthetic rate, stomatal conductance and transpiration rate of the early rice treated with river sand mud were higher at mature stage. The yield of the treatment was the highest, with a 3-year average yield of 6806.49 kg/hm 2, which was significantly higher than that of purple soil (6210.70 kg/hm2), but was not significant difference with other treatments. The difference of three years average yield of late rice among the six soils treatments was not significant. The range of total output of double-cropping rice was from 13432.91 to 14838.89 kg/hm2, which the yield of river sand mud treatment was the highest, and purple mud field treatment was the lowest, the difference between the two treatments reached significant level.关键词
