摘要
在青花菜的10叶期开始喷施不同浓度的磷酸二氢钾进行试验。结果表明:喷施磷酸二氢钾,青花菜产量较对照明显增加,其中喷施浓渡为0 3%时花球直径最大(14 17cm),产量最高(25835 13kg hm2),增产率最高(50 13%)。经方差分析,0 3%的磷酸二氢钾处理与对照之间产量差异极显著。喷施不同浓度的磷酸二氢钾,青花菜品质也有不同程度的改善,其中喷施0 3%磷酸二氢钾时,青花菜花蕾中Vc、钙、镁、磷含量均高于对照。
Foliage dressing different concentration of KH 2 PO 4 in the period of ten leaves in broccoli was carried out.The results showed that there was a marked increment both curd diameter and yield by foliage dressing KH 2 PO 4 treatments in contrast with control.When foliage dressing concentration of KH 2 PO 4 was0.3%,the curd diameter and yield were14.17cm and25835.13kg.hm 2 ,respectively,increment yield rate was50.13%at the highest level.Foliage dressing concentration0.3%has a significant difference in contrast with control by analysis of variance.Foliage dressing KH 2 PO 4 can also improve quality of broc-coli when foliage dressing concentration was0.3%,contents of Vc,Ca,Mg,P in broccoli were more than those of control.
