草木樨是一种长势旺、繁殖系数大、耐旱、耐瘠和肥效高的绿肥品种。草木樨含氮0.6％、磷0.118％、钾0.4％。它的含氮量高于豌豆、绿豆、田菁等。近年来,我区实行在油菜田套种草木樨,收到了很好的效果。1979年沭阳县十字公社用千亩油菜套种草木樨的茬口田种杂交水稻,获得了亩产千斤的产量。淮阴县王兴公社渠北大队种500亩油菜套种草木樨茬甘薯,平均单产在3,000斤以上。宿迁县蔡集公社凡湾大队连续3年500亩油菜套种草木樨,油菜平均亩产200斤左右。收油菜后20天,草木樨鲜草产量达2,000余斤。然后掩青栽水稻,水稻亩产达800斤以上,较麦茬稻增产30％ Grass mulberry is a growing Wang, breeding coefficient, drought-tolerant, barren and fertilizer-efficient green manure varieties. Grass mulberry 0.6% nitrogen, phosphorus 0.118%, potassium 0.4%. Its nitrogen content is higher than peas, mung beans, Tian Jing and so on. In recent years, our district implemented in the rape field intercropping grass clogs, received very good results. In 1979, Shuyang County Cross commune with a thousand acres of rape shrubs stubble crop field hybrid rice, access to a yield per kilogram. Huaiyin County, Wang Xing commune drafting north of 500 acres of rape mulberry planted sweet potato stubble, the average yield of more than 3,000 pounds. Suqian County, Tsai-tai commune Van Bay brigade for three consecutive years 500 acres of rape intercropping grass clogs, rape average yield of 200 pounds or so. 20 days after harvest rapeseed, Herba 樨 fresh grass production of more than 2,000 pounds. And then cover the green planted rice, rice mu produce up to 800 pounds more than wheat stubble rice yield 30%
