blighted grain

The results showed that the weight of one thousand kernels decreased and the blighted grain rate increased.

结果表明，玉米受害后果穗千粒重下降，秃顶率增加；

Path coefficient analysis shows that in contribution to rice yield, grain number per panicle comes first, the panicle number second, 1 000-grain weight third and blighted grain rate last.

通径分析表明：穗粒数对产量的贡献最大，单位面积穗数次之，千粒重再次之，空秕率最小。

The main results are as follows: every treatments enhanced full-grown grain rate, reduced blighted grain rate, increased the 1000-kernel weight and improved the grinding quality of rice at different degree.

结果表明：不同喷肥处理均有不同程度提高结实率、降低秕粒率，增加千粒重、改善稻谷碾磨品质的作用。

The days whose daily maximum of air temperature exceed 30 ℃ per-day have insignificant influence on blighted grain rate of rice.

日最高温度大于或等于30℃的天数对水稻秕粒率的影响是不显著的；

Compared with the wild type, the down-expression lines ABD showed reduced plant height, shorter leaf, white blighted grain.

与野生型相比，沉默株系ABD株高变矮，叶片变短，出现白色空秕谷。

The two regression lines of the number of single-ear ill grain and of the blighted grain rate may use the same regression coefficient, i.e. 2.249.

桂朝二号、特青一号的单穗病粒数与秕粒率的二条回归直线可以用一个回归系数即2.248。

Getting diseases easily; high rate of blighted grain and leading to a low output The effective silicon content of irrigating water used in rice field is: in the coastal area, the average content is 12 92 mg/ kg;

水稻田灌溉水有效硅含量：沿海地区平均1292mg/kg；
