近几年,我区各县在水稻夺高产的实践中,“汕优二号”表现十分突出,丰收喜讯频传,有的一季超过“双纲”。生产单位纷纷要求我司提供“汕优二号”组合的种子;而制种单位认为这组合制种难度大,产量低,不愿意制,顾虑重重。针对这种情况,我们着手研究“珍汕_(97)不育系”的生物学特性和相应的栽培技术要点,以提高其制种产量。
In recent years, in the practice of winning high yields of rice in all counties in our region, the performance of “Shanyou 2” has been outstanding. The good news of harvest has been frequent, and in some quarters, it has surpassed the “double-plan”. Production units have asked our company to provide the “Shanyou 2” combination of seeds; and seed production unit that the combination of difficult to produce seed, low yield, unwilling system, with many concerns. In response to this situation, we set out to study the biological characteristics of “Zhenshan _ (97) sterile line” and the corresponding cultivation techniques, in order to improve its seed production.
