- 摘要:
- 为黑龙江省地区紫花苜蓿的科学生产和利用,以农菁8号紫花苜蓿为试材,研究了刈割次数对紫花苜蓿草产量、品质影响。结果表明:鲜重优化组合为第一次刈割最佳时期是现蕾末期,第二次刈割最佳时期是中花期,第三次刈割最佳时间是初蕾期,留茬高度5.00 cm最为合理;干重优化组合为第一次刈割最佳时期是现蕾末期,第二次刈割最佳时期是现蕾末期,第三次刈割最佳时间是中花期,留茬高度5.00 cm最为合理。
- Abstract:
- For the scientific production and utilization of alfalfa in Heilongjiang province, taking alfalfa variety Nongjing 8 as test material, the effect of cutting frequency on the yield and quality of alfalfa was studied. The results showed that the optimal combination for fresh weight: the best time of the first cutting was at the end of squaring, the best time of the second cutting was at flowering, the best time of the third cutting was early stage, the most reasonable height of stubble was 5.00 cm; The optimal combination for dry weight: the best time of the first cutting was at the end of squaring, the best time of the second cutting was at the end of squaring, the best time of the third cutting was at flowering, the most reasonable height of stubble was 5.00cm.
