| 摘 要： | 以粳稻品种t-43为试验材料,研究膜下滴灌水稻籽粒灌浆期spad与农艺性状的相关性;叶面积指数与产量的相关性。结果表明:膜下滴灌水稻在籽粒灌浆期的spad值对水稻的农艺性状具有决定性生物作用;LAI在抽穗期最大,且其产量统计特征表明偏态系数和峰态系数都符合正态分布;抽穗期LAI与产量呈正相关。

| Abstract: | The relationship between the spad and agronomic trait in pustulation period of rice grain under mulched drip irrigation are studied by using the japonica varieties t-43 as experimental materia.The results show that the spad play a decisive role in agronomic trait in postulation period under mulched drip irrigation;the LAI gets the maximum value at heading stage;the statistical features of yield indicate that skewness coefficient and kurtosis coefficient are accord with normal distribution;LAI is positively correlated with yield at heading stage. |
