为了找出我省比光叶苕速生早熟丰产的优良绿肥品种,我们在过去品种观察的基础上,将鉴定出的罗马尼亚毛苕、土库曼毛苕、391苕子和临沧地区的毛叶苕等四个品种进行了绿肥品种比较试验。以光叶苕为对照,全试验计五个品种,重复两次,计十个小区,每小区面积为42平方米(约为0.06亩)。每亩播量4斤,用脱氟磷肥30市斤拌种,于一九七二年七月二十九日在包谷行间套种,每小区十行,行距为2.2市尺,株距为1.0
In order to find a good green manure variety with high yield and fast yield in our province, we identified the Romanian jackfruit, Turkmenistan currant, 391 Japanese razor clam and Lin Mao area on the basis of past variety observation Four varieties of green manure varieties were tested. To light leaf 苕 as a control, the entire test five varieties, repeated twice, counting ten small plots, each plot area of 42 square meters (about 0.06 acres). 4 kg per acre sowing, with 30 kg of defluorinated phosphate fertilizer, seed dressing, on July 29, 1972 intercropping in the Valley of Trades, each district ten lines, spacing of 2.2 feet, spacing 1.0
