| 摘 要： | 为探索高粱育苗移栽的最佳栽培叶龄,于2007年在仁怀市实施了高粱不同叶龄栽培对其产量的影响.结果表明:相同时期移栽,同等施肥条件下,从3叶到7叶,高粱产量随着移栽叶龄的加大而增加,5～6叶后,随着移栽叶龄的继续加大,高粱产量逐渐降低,苗龄分别为25 d和27 d的5～6叶龄,个体与群体生长协调、经济性状好、产量高(353.3 kg/667m2和321.0 kg/667m2),是高粱最佳移栽叶龄.

| Abstract: | The sorghum seedlings with different leaf-age were transplanted to study the effect on its yield for exploring the optimum cultivation leaf-age for transplant of sorghum seedlings.The results showed that the yield rised with increase of its leaf-age from 3 to 7 leaives and the yield decreased with increase of its leaf-age after 5 and 6 leavies under the same transplanting time and application amount.The yields of the transplanting seedlings between 5 and 6 leaf-age with 25 d and 27 d seedling-age were 353.3 kg/667m2 and 321.0 kg/667m2 respectively. |
