据《中国果树》2015年第5期《施钾对菠萝产量和果实品质的影响》(作者刘亚男等)报道,为探索钾在大田试验条件下对菠萝产量和品质的影响,从而建立菠萝高产、高效施肥技术,以期为广东省优质菠萝生产提供参考。以巴厘菠萝为试验材料,采用大田试验方法,研究4种施钾量(0、250、500、800 kg/hm2)对菠萝叶片叶绿素含量、植株各部位钾素含量及果实产量、品质
According to the report of “Chinese Fruit Tree” No.5/2015 “Effect of Potassium Application on Pineapple Yield and Fruit Quality” (by Liu Ya-nan et al.), In order to explore the effect of potassium on the yield and quality of pineapple under field test conditions, Efficient fertilization technology, with a view to provide a reference for the production of high-quality pineapple in Guangdong Province. Taking the pineapple of Bali as test material, field experiments were conducted to study the effects of four K application rates (0, 250, 500 and 800 kg / hm2) on the chlorophyll content, plant potassium content and fruit yield,
