本试验旨在测定N、P、K在香蕉植株生长中所起的作用.为此,进行定期观察植株的生长量,最后将果实连同整棵植株全部取回,分别对不同部位加以分析,以确定营养吸收和积累.田间试验不能决定P、K在香蕉生产中所起的作用(Du Plessis,LangeneggerKoen,Kuhne和Smart,1977;Koen,Smart和Kruger,1976),主要是因为这些“老”试验地含有较高的P、K水平.再者,P、K水平低的新土也不适于田间试验.为此,本试验决定采用含P、K水平低的土壤进行盆栽试验.
The purpose of this experiment is to determine the role of N, P and K in the growth of banana plants.To do this, we regularly observe the growth of the plants and finally recover the fruits together with the whole plant and analyze the different parts to Determining nutrient uptake and accumulation. Field trials did not determine the role of P and K in banana production (Du Plessis, Langenegger Koen, Kuhne and Smart, 1977; Koen, Smart and Kruger, 1976), mainly because these “old” In addition, the new soil with low levels of P and K was not suitable for field experiments.Therefore, we decided to use pots with low levels of P and K for pot experiments.
