杂交稻的混杂问题,仍然是当前生产上的一个大问题。对于杂株的类型及其对产量的影响,近年一些地方进行了调查研究,但是一般都不能指明在实际生产条件下不同的杂株率对产量影响的确切结果。本试验旨在通过对若干杂株率不同的杂交稻种子,在与大面积生产相似条件下的试验,研究杂株率对产量的具体影响,以期为生产上更好地利用杂交稻提供依据。 The hybrid problem of hybrid rice is still a big problem in current production. The types of hybrids and their impact on the yield in some places in recent years conducted a survey, but generally can not specify the actual production conditions of different specific plant yield on the exact results. The purpose of this experiment is to study the specific effects of the rate of hybrid plants on the yield of hybrid rice seeds with different percentages of hybrid plants under similar conditions to those of large-scale production so as to provide a basis for better utilization of hybrid rice in production.
