5种缓释肥在结球甘蓝上的应用效果

采用田间试验方法,研究了5种不同种类缓释肥在结球甘蓝上的施用效果。通过对结球甘蓝田间植物学性状、产量等方面的分析,结果表明:与常规施肥方法相比,俩控缓释肥在采收期植物学性状表现优良,667 m~2较常规施肥增产6.6%,增加经济效益1728.22元;榕风缓释肥虽没有提高产量,但降低了肥料施用量,节省了生产成本,从而提高了经济效益。综合分析,俩控缓释肥及榕风缓释肥是较为经济适用的缓释肥,奥绿肥、撒作灵不适宜在结球甘蓝上施用。

The Application Effect of 5 Kinds of Slow-release Fertilizer on Cabbage

Abstract: Using the field test method, the effect of 5 different kinds of slow-release fertilizer oncabbage was studied. Through the analysis of cabbage field agronomic traits and yield, the results showed that compared with the conventional fertilization method, Lia Kong slow-release fertilizer treatmentperformed excellent on the botanical traits, increased the production by 6.6% per 667 m2, and improvedeconomic benefits by 1 728.22 yuan. Although the Rong Feng slow-release fertilizer did not increase the yield,it reduced the use of fertilizer, saved the production cost, and thus increased the economic benefits. On the basisof comprehensive analysis, Lia Kong and Rong Feng slow-release fertilizer had enough economic applicability,while Osmocote and Sazolene slow-release fertilizer were not suitable on the growth of cabbage.
