摘要
为探讨山药种植过程能否施用氯肥以及氯肥用量等问题,以‘大和长芋’山药为试材,设置了6个不同的氯肥处理,通过测定山药的出苗率、芦头长、长度、茎粗和产量等指标,初步筛选出氯肥的施用范围。结果表明,6个氯肥处理的山药出苗率和芦头长无差异;而KCl用量为5 kg/667 m^(2)和10 kg/667 m^(2)时山药长度,茎粗和产量显著高于对照;KCl用量为15 kg/667 m^(2)和20 kg/667 m^(2)时,山药长度和茎粗低于对照;KCl用量23.7 kg/667 m^(2)时,山药长度、茎粗和产量与对照无差异,综合出苗率、芦头长、长度、茎粗、产量及投入等因素,山药最适氯肥施用量在5~10 kg/667 m^(2)左右。
To explore the application and amount of chlorine fertilizer,the‘Dahechangyu’yam was used as research materials,and six treatments were set up.The emergence rate,head length of reed,length,stem diameter and yield of yam was measured,and the application range of chlorine fertilizer content was selected preliminarily.The result showed that there was no difference in emergence rate and head length of reed under 6 chlorine fertilizer treatments;the length,stem diameter and yield of yam were higher significantly than those of the control group when the amount of KCl was 5 kg/667 m^(2) and 10 kg/667 m^(2),and the the length and stem diameter were lower than those of the control group when the amount of KCl was 15 kg/667 m^(2) and 20 kg/667 m^(2),and the length,stem diameter and yield of yam were no difference from those of the control group when the amount of KCl was 23.7 kg/667 m^(2).Comprehensive the above indices and the input factors,the optimal application of chlorine fertilizer of yam is 5-10 kg/667 m^(2).
