在2013~2014年,调查了安徽弋江大叶籽、湘肥4号、闽紫6号、南昌种4个绿肥品种的生长特性、鲜草产量,筛选出适宜上栗县域种植的绿肥品种。试验结果表明,4个绿肥品种茎、叶特征类似,叶色和叶形略有差异;盛花期安徽弋江大叶较早,其余品种迟2天左右;安徽弋江大叶籽和南昌种鲜草产量较低,分别为1718kg/667m2和1802kg/667m2,显著低于闽紫6号和湘肥4号,分别为2744kg/667m2和2367kg/667m2。结合各个品种特征,可以认为闽紫6号、湘肥4号比南昌种和安徽弋江大叶更适宜上栗县域种植。
From 2013 to 2014, the growth characteristics and fresh grass yield of four green manure varieties, Yeyi, Xiangfei 4, Minzi 6 and Nanchang, were investigated. The varieties of green manure suitable for planting in Shangli County were screened out. The results showed that the four green manure cultivars showed similar stem and leaf characteristics with slight differences in leaf color and leaf shape. The large-leaved leaves of Anhui Yijiang were earlier in flowering and the remaining varieties were about 2 days later. Grass yield was lower at 1718kg / 667m2 and 1802kg / 667m2 respectively, significantly lower than that of Minzi 6 and Xiangfei 4, which were 2744kg / 667m2 and 2367kg / 667m2, respectively. Combined with the characteristics of each variety, it can be considered that Minzi 6 and Xiangfei 4 are more suitable for planting in Shangli County than Nanchang and Anhui Yijiang big leaves.
