通过上述分析,我们可以看到,若以天然荒坡为参照地块,那么人工林地和人工草地都很明显地提高了土地的生产力。所以从土地资源合理利用的观点来看,如何在水资源有限的情况下,在有利于提高地力、有利于生态环境改善的前提下,改变传统的撂荒制度,大力种草种树,推行粮草轮作,是提高土地生产力的有效途径。4、农田土壤水分状况。本区作物可分两大类:一是夏田作物,二是大秋作物。前者秋
From the above analysis, we can see that if the natural barren plot is used as a reference plot, both the planted and artificial grasslands obviously increase the productivity of the land. Therefore, from the perspective of rational utilization of land resources, under the condition of limited water resources, under the premise of being conducive to improving soil fertility and conducive to the improvement of ecological environment, we should change the traditional shortage management system and plant grass vigorously to promote crop rotation Is an effective way to improve land productivity. 4, farmland soil moisture status. Crops in this area can be divided into two categories: First, summer field crops, and second, autumn crops. The former autumn
