根系在土壤中的生长和分布(图)
植物根系在土壤中分布的深度和广度常因植物的种类、生长发育的好坏、土壤条件以及人为因素的影响的不同而异。根在土壤中的分布分为深根系和浅根系两类。有些植物的主根发达，向下垂直生长，长入土壤的深层达2～5米，甚至10米以上，这种向深处分布的根深，称深根系。如大豆、蓖麻、马尾松等。而另一些植物的主根不发达，侧根或不定根较主根发达，并以水平方向朝四周扩展，并占有较大的面积，因此这种根系常分布在土壤的浅层（1～2米），称浅根系，如车前、小麦、水稻等。一般直根系多为深根系，须根系多为浅根系。但不是所有的直根系都属于深根系。根的深度在植物不同生长发育期也是不同的，一般规律是根系和植物的地上部分具有一定的相关性，如任何植物苗期的根均很浅。农作物的根系大都分布在土壤的疏松耕作层里，适当的深耕可以增加根系的吸收面积，使作物获得高产。此外，不同作物进行间作套种时，必须考虑这些作物的根系在土层中的分布状态，如用深根系和浅根系作物互相搭配，能够分别吸收利用不同深度土层中的肥水，则有利于提高单位面积的产量。
