春箭舌豌豆是优良的草、料、绿肥兼用的一年生豆科作物。我国自五十年代引进,因表现耐旱、耐瘠、稳产、适应性广而颇受群众欢迎。由于春箭舌豌豆品种较多,各地自然生态条件和耕作管理水平不同,所以生产水平亦有所差别。1984年我们进行了333/A、324、881和879等不同品种的比较试验。试验地位于甘肃省中部干旱地区静宁县的甘沟,海拔1700米,年均温7.9℃,年绝对最高气温28.9℃,生长季(4—8月)日平均温度16.5℃,降水量413.05毫米,蒸发量700.7毫米。试验地前茬为冬小麦,1983年秋季由拖拉机翻耕,1984年3月初播种前进行了整地、浇水。播前用钉齿耙和(?)耙(?)两
Spring tongue tongue peas are excellent grass, material, green manure and annual bean crops. Since the introduction of China in the fifties, due to the performance of drought, barren, stable production, wide adaptability and popular among the public. As the spring tongue tongue peas varieties more, around the natural ecological conditions and farming management level is different, so the production level is also different. In 1984 we conducted 333 / A, 324,881 and 879 and other different varieties of comparative experiments. The experimental site is located in Gangou at Jingning County in the arid region of Gansu Province. The average annual temperature is 7.9 ℃ and the annual absolute maximum temperature is 28.9 ℃. The average temperature of the growing season (April-August) is 16.5 ℃ and the precipitation is 413.05 mm. Evaporation 700.7 mm. The test crop was winter wheat, plowed down by a tractor in the fall of 1983, and soil preparation and watering were carried out before sowing in early March 1984. Before sowing rake and rake (?) Two
