杂交水稻的再生能力较强,早稻收割后,可以利用禾蔸茎节上的休眠芽萌发进行再生栽培。我们对它的若干生理特性进行了观察。一、试验过程观察的品种组合有南优二号、金优二号和汕优三号。早造同于8月16日播种,4月23日移植,规格6×5寸,每蔸插两苗。南优二号和金优二号8月5日收割,亩产分别为834斤和830斤。汕优三号8月18日收割,因生长后期受稻蝽象危害,亩产520斤。早稻收割时留蔸高2—3厘米。南优二号和金优
Hybrid rice has strong regenerative ability. After the early rice is harvested, it can be regenerated by the dormant bud germination on the stem section of the grass. We observed some of its physiological properties. First, the experimental process observed varieties combinations Nam You II, Kim You 2 and Shanyou 3. As early as the same on August 16 sowing, April 23 transplant, size 6 × 5 inch, insert two per 蔸. Nam You 2 and Kim You 2 harvest on August 5, respectively, 834 kg and 830 kg per mu. Shanyou three harvest on August 18, due to the late growth stage by the stink bug, 520 kg per mu. Early rice stay 蔸 high 2-3 cm when harvesting. Nam You 2 and Kim You
