摘要
简述了橡胶树大量元素的作用与营养规律,针对目前橡胶园普遍存在肥力下降,氮、钾不足,磷肥利用率较低等情况,指出在天然橡胶树施肥过程中应优化肥料管理,进行平衡施肥、配方施肥,提高肥料利用率,对降低橡胶栽培生产成本,提高橡胶产量,保护环境和促进农业的可持续发展有重要意义。
Through studying the use and rules of macro-element of natural hevea brasiliensis, aiming at the circumstances that fertility descends, nitrogen and potassium lack, and utilizing ratio of phosphorous fertilizer is low in rubber plantations, this review puts forward that fertilizer utilizing ratio should be laid more emphasis; and nutrition administration should be optimized; balanced fertilization, prescription fertilization and progress in fertilization technique should be carried out to make a large promotion for yield of hevea brasiliensis, and bring down the cost of Hevea brasiliensis cultivation. These are significant for environmental protection and promoting agricultural sustainable development.
