众所周知,土壤生物学特性是土壤肥力的重要指标。以往的研究常以土壤理化性质及产量高低来评价土壤肥力的高低,这有它合理的一面,但还不能真正反映土壤肥力的实质,因为土壤养分等处于动态的变化之中,所以近年来不少研究者提出以土壤生物学重要特性——土壤酶活性作为评价土壤肥办的指标。我们为了探讨蔗园土壤肥力的演变状况,采集了一部分具有代表性的蔗园土
As we all know, soil biological characteristics of soil fertility is an important indicator. Previous studies often used soil physical and chemical properties and yield to evaluate the level of soil fertility, which has its reasonable side, but can not really reflect the essence of soil fertility, because of soil nutrients in a dynamic change, so in recent years Fewer researchers put forward the important characteristics of soil biology - soil enzyme activity as an indicator of soil fertility evaluation. In order to investigate the evolution of soil fertility in sugarcane field, we collected some representative sugarcane soil

我用一个下午，观察老鼠洞穴。我坐在一蓬白草下面，离鼠洞约二十米远。这是老鼠允许我接近的最近距离。再逼近半步，老鼠便会仓皇逃进洞穴，让我什么都看不见。 老鼠洞筑在地头一个土包上，有七八个洞口。不知老鼠凭什么选择了这个较高的地势。也许是在洞穴被水淹了多少次后，知道了把洞筑在高处。但这个高它是怎样确定的？靠老鼠的寸光之目，是怎样对一片大地域的地势作高低判断的？ 老鼠的这个洞的确筑在高处。以我的眼光，
