我省种植绿肥具有悠久的历史,种植的品种主要有紫云英、苕子等。但是,由于传统的绿肥种植观念的束缚,长期以来,种植绿肥主要作为土壤有机肥源,限制了绿肥自身作用的充分发挥。为此,应改变观念,充分发挥绿肥养地养畜的双重效用,利用其地下部分增加土壤有机质,维护土壤的良好结构和氮素循环;地上部分作为畜禽饲料,过腹还田。这样既扩大了饲料来源,又提高了地力,使农牧业生产系统保持良性循环。 Planting green manure in our province has a long history, the cultivated varieties are mainly vetiver, prickly heat and so on. However, due to the traditional concept of green manure cultivation, planting green manure has long been mainly used as a source of organic manure, which limits the full play of green manure. To this end, we should change their concept, give full play to the dual effect of green manure livestock raising, the use of its underground parts of soil organic matter to improve the soil structure and nitrogen cycle; the ground as livestock feed, belly to the field. This not only expands the source of feed, but also improves the ground force, so that the farming and livestock production system maintains a virtuous circle.
