研究表明,本田湘矮早10号、威优35分蘖初期接种二化螟蚁螟侵害造成枯心后,余留稻株具有一定的自然补偿能力。每丛枯心苗在1-6株的范围内,两供试品种其苗补偿分别为41.67%和32.13%,稻谷损失补偿分别为32.19%和39.13%。一般低位分蘖的补偿能力大于高位分蘖,杂交稻威优35大于常规稻湘矮早10号。稻谷损失补偿的途径主要是靠增穗、增粒重来弥补。水稻根系伤流量、叶绿素含量、光合作用强度和叶片、叶鞘全N以及可溶性糖等生理指标的测定结果表明,分蘖期稻株受害后,余留稻株的生理功能,随每丛枯心苗数的增多而加强,而且不同品种、不同年度间存在着差异。
Studies have shown that Honda Xiang Aza 10, Weiyou 35 at the initial tillering stage after the inoculation of rice stem borer caused by dry, the remaining rice plants have a natural compensation ability. In the range of 1 to 6 strains, the compensations of seedlings of two tested cultivars were 41.67% and 32.13% respectively, and the losses of paddy losses were 32.19% and 39.13% respectively. Generally, the compensatory ability of low tillers was higher than that of high tillers. The hybrid rice Weiyou 35 was larger than that of conventional rice Xiangcai Zao 10. The main way to compensate for the loss of paddy is to make up by increasing spike and grain weight. The results showed that the physiological functions of the remaining rice plants at the tillering stage were as follows: the number of trapping flow, chlorophyll content, photosynthetic intensity, total N and soluble sugar in leaves, Increase and strengthen, and different varieties, there are differences between different years.
