- 摘要:
- 以空育131水稻为试验材料，研究不同土壤含盐量处理对盆栽水稻生育期和农艺性状的影响。结果表明：随着土壤含盐量的增加，水稻的生育期延长、株高变矮、茎粗变细、有效穗数和产量有较大幅度地下降。通过主要性状和土壤含盐量对水稻产量的回归分析表明，在不同土壤含盐量的条件下，有效穗数是影响产量的主要因素。
- Abstract:
- Taking Kongyu 131 as experimental material,the effect of different salt contents in soil on rice growth period and agronomic characteristics of pot experiment were studied.The results showed that with the salt content increased，the growth period of rice prolonged，plant height，stems diameter，number of productive ear and yield decreased significantly.The regression analysis showed that under salt stress the number of productive ear was a very important factor affecting the yield of rice.
