摘要
受自然环境制约,山区只能种植小杂粮。种植小杂粮的耕地一年中有一大半的时间裸露在风蚀雨侵中,遇风则扬沙,遇雨则径流,雨过则旱灾。而且耕地只用不养。小杂粮传统的种植方式,一是产量上不去;二是给当地的生态环境带来一定的负面影响,致使本来就十分脆弱的山区环境雪上加霜。试图在小杂粮生产过程中找寻出既小杂粮高产,又能让当地的生态环境形成良性循环,使小杂粮产区经济效益和生态效益获得双赢的对策来。
Limited by natural conditions, minor crops can only be planted in mountainous area, The farmland used to plant minor crops naked for about 9 months each year, When it winds, there is dust, when it rains, there is run-off; after raining, it is usually drought, Most farmers do not pay much attention to soil fertilization, The problems in planting minor crops are low yield and negative effect on local ecological environment, The purpose of this study was to find a better way to get high yield of minor crops, make local ecological environment into sound circulation, and also get ,economical and ecological benefit.
