盲目地、不适量地施肥现象在我省花生生产中仍极普遍。商品经济较为发达的地区如广州、珠江三角洲等,往往过量施用化肥,尤其是氮肥,有的亩施尿素高达80—100斤;经济文化较落后的海南、雷州半岛等地则少施或不施肥料,花生单产很低;粤北石灰岩地区则较普遍大量施用石灰,高的亩用量达400—500斤以上。因此,推行因土施肥有利于避免或减少上述情况 Blindly, ill-suited to the phenomenon of fertilization in peanut production in our province is still very common. More economically developed areas such as Guangzhou, the Pearl River Delta, etc., often over-fertilization, especially nitrogen fertilizer, and some acres of urea up to 80-100 pounds; less economically and culturally backward Hainan, Leizhou Peninsula and other places less or not Shi Fertilizer and peanut yield is very low; limestone area in northern Guangdong is more commonly used lime, high amount of 400-500 pounds of mu. Therefore, the implementation of soil fertilization is conducive to avoiding or reducing the above situation
