以沈稻47为试验材料,研究不同叶龄、秧盘及穴距对水稻产量和主要农艺性状的影响。结果表明:叶龄和穴距相同条件下,最高分蘖数和有效穗数均为钵盘高于软盘,相同叶龄和秧盘条件下单位面积茎蘖数随穴距的增大而减少。4.1叶龄处理的产量显著高于5.7叶龄和2.5叶龄处理的产量。穴距20cm处理的产量最高,平均产量为11.84t/hm~2,显著高于穴距27cm处理,但与13cm穴距处理的产量差异不显著。钵盘育苗有效穗数较高,软盘育苗穗粒数、成粒率和千粒重均较高,从而更易获得高产。软盘育秧及钵盘育秧与4.1叶龄及穴距20cm的组合产量最高,分别为12.90和12.58t/hm~2。
Using Shen-ye-47 as test material, the effects of different leaf ages, seedling traps and pitches on yield and agronomic traits of rice were studied. The results showed that under the same condition of leaf age and hole distance, the highest number of tillers and effective panicles were all higher than that of the floppy disk, and the number of tillers per unit area under the same leaf age and seedling tray decreased with the increase of the hole distance. The yield of 4.1 leaf age treatments was significantly higher than that of 5.7 leaf age and 2.5 leaf age treatments. The hole spacing of 20 cm was the highest, with the average yield of 11.84 t / hm ~ 2, which was significantly higher than that of 27 cm. However, the difference of yield between the hole and 13 cm was not significant. Bowl seedling effective spikelets higher, floppy disk nursery grain number, granulation rate and grain weight are higher, which is more likely to obtain high yield. The combination yield of the disk-growing seedling and the pot-tray cultivating seedling with the leaf age of 4.1 and the hole distance of 20cm were the highest, which were 12.90 and 12.58t / hm ~ 2, respectively.
