Introduction experiment of leguminous forages in the dry and hot valley of Yuanmou region
摘要
Abstract
An experiment was conducted to select the suibtable plant legume forages from 16 legume fora ges for the dry and hot valley in the Yuanmou region. This study showed that Centrosema pubescens, Flemingia macropylla, and Desmodium ovalifolium did not seed and the other 13 plant species grew well. Leucaena leucocephala showed the highest yield with a lange number of leaves and good palatability. The top yield was L. leucocephala K636, L. leucocephala, L. leucocephala cv. Reyan No. 1 with 26 93a. 9 kg/ha, 24 882.6 kg/ha, 22 459.2 kg/ha, respectively. The sheep preference for these plants was 5. The Neotononis wightii cv. Tinarroo, Acacia farnesiana and Sesbania grandiflora came to the second due to higher yield and good palatability, and ratio of dry weight to fresh weight and stem/leaf ratio of N. wightii cv. Tinarroo was 0.27 and 0.73. The lowest yield forage was Desmodium ovalifolium with 920.8 kg/ha, and its DW/FW ratio was 1.96. This study suggested that D. ovalifolium was not suitable to be planted in Yuanmou region; and the pest control for Cratylia argentea should be taken during its bloomin5 period to increase pod numbers.关键词
