摘要
滴灌施肥是解决聚乙烯地膜辣椒生产中施肥和灌溉问题的技术之一。钾(K)是影响植物生长发育的重要宏观营养元素之一，它在植物体内的生化和生物物理过程中发挥着重要作用。本研究的目的是确定滴灌聚乙烯膜辣椒生产的最佳钾肥来源和最佳钾肥用量。该研究于2018年1月至7月在茂物农业大学热带园艺研究中心Tajur实验农场进行。试验设计以KCl、ZK、NPK为主要钾源，分5个水平(0、68、136、204、272 kg K2O)为试验区。Ha-1)作为子情节。结果表明，最适钾用量为101.11 kg K2O。最高产量为2.26 t.ha-1。施用氮磷钾和氯化钾的辣椒作物单株果重、亩产果重和亩产果重最大。
Potassium Sources and Rates for Drip Irrigated Polyethylene Mulched Chilli Pepper
Fertigation with drip irrigation is one of the technologies to solve fertilization and irrigation problems in chilli pepper production using polyethylene mulch. Potassium (K) is one of the important macro nutrients that affect plant growth and development due to its roles in the biochemical and the biophysical processes in plants. The objective of this study was to determine the best sources and the optimum rates of potassium for drip irrigated polyethylene mulched chilli pepper field production. The study was conducted in January until July 2018 at Tajur Experimental Farm, Center for Tropical Horticulture Study, Bogor Agricultural University. The experimental design was a split plot with the K sources (KCl, ZK, NPK) as main plots and K rates that consisted of five levels (0, 68, 136, 204, 272 kg K2O. ha-1) as sub-plots. The results showed that the best optimum rate of K to produce fruit is 101.11 kg K2O.ha-1 with a maximum yield of 2.26 t.ha-1. Chilli crops fertilized with NPK and KCl had the greatest fruit weight per plant, fruit weight per plot, and fruit weight per hectare.
