摘要
通过田间小区试验,探讨了喷施中量元素水溶肥对甘蓝产量、品质及效益的影响。结果表明:在移栽后的15、25、35 d,用60 g/667m^2中量元素水溶肥对清水60 kg/667m^2喷施整个植株,相比"常规施肥+清水"处理和"常规施肥"处理,分别使甘蓝产量提高6.2%和7.3%,增加收入296.5和320.4元/667m^2;同时,喷施中量元素水溶肥显著提高了甘蓝的可溶性蛋白质、可溶性糖和VC含量,显著降低了其硝态氮含量。该施肥措施简单实用,增产提质增效明显,建议在甘蓝生产上推广应用。
The field plot experiments were arranged to explore the effect of spraying medium element water-soluble fertilizer on the yield,quality and profit of cabbage(Brassica oleracea L.).The results showed that 15,25 and 35 days after transplanting,each 900 g medium element water-soluble fertilizer was applied with 900 kg fresh water per hectare in whole plant spraying,which increased the yield of cabbage by 6.2%and 7.3%,and increased the income by 4447.5 yuan/hm2 and 4806 yuan/hm2 in comparison with spraying water+conventional fertilization,and conventional fertilization,respectively;furthermore,it significantly increased the soluble protein,soluble sugar and VC contents of cabbage,and significantly reduced nitrate nitrogen content.The operation of spraying medium element water-soluble fertilizer on cabbage is simple and practical with obvious increases in yield and quality,which is recommended promotion in cabbage production.
