分蘖是水稻的固有特性,分蘖的发生是水稻生长与环境条件统一的结果,合理利用分蘖是水稻高产栽培中的重要一环。对水稻分蘖的研究已有不少报道,其中对分蘖的利用存在有不同的看法。因此,有必要进一步研究水稻分蘖对增产的作用以及不同群体条件下分蘖发生和成穗的关系,以期明确生产上能充分利用分蘖的程度。
Tillering is an inherent characteristic of rice. The occurrence of tillering is the result of the unification of rice growth and environmental conditions. The rational use of tillers is an important part of high yielding cultivation of rice. There have been many reports on the tillering of rice, among which there are different opinions on the utilization of tillers. Therefore, it is necessary to further study the effect of tillering on yield increase and the relationship between tillering and ear formation under different population conditions, with a view to clarifying the extent to which tillers can be fully utilized in production.
