除了少数例外,西非沿海的椰园都严重缺钾,有许多还严重缺氮,产量因此不高。已经证实,施用化肥可以矫正椰园缺钾和缺氮,使产量增加一倍至二倍。然而为了使施肥有效起见,必须在适宜的时机遵照一定的条件和规则施用肥料,这是很重要的。 With few exceptions, coconut palms along the coast of West Africa suffer from a serious shortage of potassium and many are also severely nitrogen-deficient with low yields. It has been confirmed that the application of fertilizers can correct potassium deficiency and nitrogen deficiency in coconuts, doubling or doubling production. However, in order for fertilization to be effective, it is important that fertilizers have to be applied in accordance with certain conditions and rules at the appropriate time.
