粒用高粱杂交种的寿命1200天以上,属多年生禾本科植物。其在整个生命过程中可有多个繁殖后代的周期。周期长短因品种而异,一般80—150天。在雨季和旱季明显的热带地区,一个繁殖周期结束后。旱季开始,原生植株(Original growth Plant)的根和茎进入休眠期,待雨季开始后,又从茎的基部萌发新芽,进行第二个繁殖后代的周期,表现出有较强的耐旱特性和再生能力。粒用高粱杂交种二年生和三年生植株与一年生植株的主要农艺性状及单株产量没有显著差异。杂种优势稳定。进行再生栽培,可以“一种多收”。降低生产成本,提高经济效益。
Grain sorghum hybrids with a life of more than 1200 days, is a perennial gramineous plants. It can have multiple cycles of breeding offspring throughout life. The length of the cycle varies according to the species, usually 80-150 days. In the rainy and dry season obvious tropical areas, after a breeding cycle. At the beginning of the dry season, the roots and stems of the original growth plant entered dormancy period. After the onset of the rainy season, new sprouts were germinated from the base of the stem and the cycle of the second breeding offspring showed strong drought tolerance. Regenerative ability. The main agronomic traits and yield per plant of biennial and annual perennials of sorghum hybrids were not significantly different. Heterosis is stable. Regenerative cultivation, you can “a kind of more income.” Reduce production costs, improve economic efficiency.
