不同穴株数对寒地水稻性状及产量影响

Effect of Different Planting Hole Strainson on Characters and Yield of Cold Rice

为探索寒地水稻的最适宜插秧穴株数,采用小区对比试验设计,对5个水稻品种的4个插秧穴株数进行试验。试验结果表明:寒地水稻同一品种不同处理之间的生育期无差异,不同品种之间存在一定的差异;穴株数越多的处理综合发病率越高;各处理之间的产量构成因子都存在一定的差异,且变化规律不明显;空育131、三江1号、龙粳26、龙粳29、垦稻15最适插秧穴株数分别为9株、9株、5株、3株、3株。

Through plot experimental comparison design,4 planting hole strains of five rice varieties were established in order to find out the most appropriate planting hole strains of local cold rice.The experimental results showed that different treatments in the same variety of the growth period were no difference,there were some differences among the different varieties of cold rice.The more planting hole strains treatment,the more comprehensive incidence.There were some differences in the yield components among the treatments,and the variation was not significant.The most appropriate planting hole strains of Kongyu 131,Sanjiang No.1,Longjing 26,Longjing 29,Kendao 15 were 9,9,5,3,3.
