The mass loss patterns of four type litters fitted exponential model, and the decomposition rate could be well predicted by their lignin/N ratio.

结果表明：与对照相比，降水量减少条件下，蒙古栎叶凋落物的初始N、P、K浓度显著升高，初始木质素浓度显著降低，凋落物分解速率大，N、P、K矿化率高，N和P固持时间缩短；降水量增加情况下，其凋落物初始N浓度显著降低、木质素浓度显著升高，N、P、K矿化率低，N和P固持时间延长。4种类型叶片凋落物的质量损失过程均符合指数降解模型，分解速率可以由凋落物木质素／N来预测。

Compared with 810S,the total photosynthetic pigment content of Biao 810S was aabout 50%lower;which was the main cause of the yellow green leaf.2、The spikelet numbers,stigma exsertion rate and flowering time of Biao 810S were same as that of 810S.There were no significant difference of the agronomic traits between the the cross combination which came from the maintainers D100 and R96-1 and the combination from 810S.3、The photosynthetic rate of Biao810S was higher than 810S under strong light and lower under weak light.

叶绿素含量下降是标810S叶片呈淡黄绿叶色的根本原因。2、标810S的颖花数、柱头外露率和开花时间与对照基本相当，与恢复系D100和R96-1配制的杂交组合农艺性状与用810S配制的相应推广组合无明显差异，表明标810S可替代810S应用于两系杂交水稻，其淡黄绿叶色性状可应用于杂交制种田的不育系群体除杂，同时可根据幼苗期淡黄绿叶色性状植株的比例用于鉴定杂交组合中不育系的混杂率。3、弱光条件下标810S的光合速率低于810S，强光条件下标810S光合速率比对照高，且标810S在光强2400μmol·m~(-2)·s~(-1)以下没有光饱和点和"午休"现象。
