地处峨嵋岭台地的万荣县,是个典型的干早县份,廿年来平均年降雨量547.5毫米,其中6-8月份降雨量占全年的1/2左右。1966年以前曾引种草木栖,冬前和早春在麦田套种,由于春旱,捉不住苗,而小麦拔节至成熟期间耗水量大,草木栖由于缺水和荫蔽,苗弱苗小,干烤死亡。群众认为旱地不能种绿肥,十多年来绿肥近乎绝迹。近年来,我们在该县南景大队进行了绿肥种植试验。一、旱地发展绿肥的可能性每产1,000斤柽麻鲜草,约耗水120-140毫米。1978年6月5日播种,7月22日
Wanrong County, located on the Emei Mountain platform, is a typical Qianzha county, with an average annual rainfall of 547.5 millimeters over the past 20 years, with precipitation accounting for about 1/2 of the year in June-August.
