- 摘要:
- 为了加快黑龙江省饲草高粱的种植,促进畜牧业发展,对健宝和龙草1号2个品种分别进行不同刈割次数的产量和刈割后不同追肥水平下肥效利用率比较的研究。结果表明:健宝刈割1茬的产量高于刈割2茬产量,龙草1号刈割2茬的产量高于刈割1茬产量;健宝刈割1茬和刈割2茬追肥40 kg?hm-2肥效利用率高;龙草1号刈割1茬追肥80 kg?hm-2肥效利用率高,刈割2茬追肥40 kg?hm-2肥效利用率高;农艺性状方面,二者再生和分蘖能力强,抗病、抗倒伏,都是优良的饲草高粱品种。
- Abstract:
- In order to speed up the Heilongjiang province forage sorghum planting and promote the development of animal husbandry,the studies on the yield of the different clipping frequency and different fertilizer use efficiency under different fertilization of the Long grass No.1 and Jumbo were conducted.The result indicated that yield of Jumbo of cutting once was higher than cutting twice,the yield of Long grass No.1 of cutting twice was higher than cutting once.Jumbo of cutting once and twice had higher fertilizer use efficiency when applying 40 kg?hm-2.The Long grass No.1 of cutting once had higher fertilizer use efficiency when applying 80 kg?hm-2,cutting twice had higher fertilizer use efficiency when applying 40 kg?hm-2.In agronomic characteristics,the Jumbo and Long grass No.1 had some features of strong regeneration ability and strong tiller ability,resistance to disease and lodging,they were both excellent sorghum varieties.
