打肥水井和打普通井一样,不同的是要注意井深的部位。肥水一般埋藏在地面以下30米内的较粘土层中。所以打井深度不能仅从沙层好坏和出水量来定,如打到含水沙层淡水多了,井水含氨量就大大降低。但井水含氮量高的,也可打入沙层(见图1)。 Play fertilizer wells and ordinary wells hit the same, the difference is to pay attention to the depth of the site. Fertilizer water is generally buried in the clay within 30 meters below the ground. Therefore, the depth of drilling can not only be determined by the quality of the sand and the amount of water to be set, such as playing fresh water and more sandy, well water greatly reduced ammonia. However, high water content of well water, but also into the sand (see Figure 1).
