插秧规格对水稻品种牡丹江32产量及产量性状的影响
Effect of Different Transplanting Models on Yield and Yield Components of Rice Variety Mudanjiang 32
摘要
Abstract
In order to study the cultivation pattern of rice varieties ,taking Mudanjiang 32 as test materials ,the effect of transplanting density and planting seedlings per hole on the yield components were studied .The re‐sults showed that sparse planting had significant effect on increasing of panicle number and Mudanjiang 32 was not suitable for sparse planting .There was significantly positive correlation between planting seedlings per hole and panicle number .Both the seedling number and spike number in direct path analysis and panicle number per hole to panicle number in indirect path analysis were significantly positive correlation ,which implied that plant‐ing seedlings per hole should be enhanced .The secondary branch was the most active factor ,which positively determined to the grain number per panicle .The yield was 8 658 .0 kg·hm‐2 and suitable transplanting model for Mudanjiang 32 should be 30 cm × 12 cm and 6 seedlings per hole .关键词
