The result showed that the HTT rice was superior to the other two hybrids in terms of plant height,the length and width of the flag leaf,the number of grains per panicle,and yield;and HTT rice were even more superior to the other two hybrids in terms of the breaking resistance of the first,second and third internode.

The Screening of Optimum Ratio of Insecticide Mixture against Sesamia inferens Larvae;

The absorption,distribution and utility of nitrogen in plant of high-yielding rice;

When plateau rice seedling of two or five leaves stage were subjected to low tempenature stress, the effects on SOD activity of leaf is differential: two leaves stage decreased generally but five leaves stage inceased except the cultivar with weak cold resistance and lower sea level cultivation.
