拉巴豆不同生长时期的产量与营养价值评定

Evaluation of the Yield and Nutritive Value of at Different Growing Stage in Dolichos lab lab

采用饲料常规分析方法,对拉巴豆不同生长时期的产量进行测定,并对其不同生长时期的常规营养成分进行测定。结果表明:拉巴豆随着生育期的延长在现蕾期产鲜草量最大,结实期产干草量最大,粗蛋白在现蕾期达到最高值,Ca、P在现蕾期含量基本稳定,相对也较高,拉巴豆刈割饲用的最佳时期是现蕾期。

In the paper, feed conventional analysis method was used to determine the yield and common nutrition component of Dolichos lab lab at different growing stage. The results showed that the fresh grass yield was the highest at squaring period with increasing of growth period, the hay yield was the most during productive phase, crude protein content reached its maximum, Ca and P content were basically stable, and they were much higher, so the best harvest period of Dolichos lab lab was squaring period for high biomass.
