添加中微量元素是提高蔬菜产量的有效措施,同时,也能够对蔬菜的品质产生一定的影响。通过盆栽试验研究不同梯度硅钙钾肥对苏州青油菜产量和营养品质的影响。结果表明:施加600kg/hm2、1 200kg/hm2、1 800kg/hm2、2 400kg/hm2、3 000kg/hm2的硅钙钾肥能分别增产31.66%、32.90%、34.57%、33.77%和33.84%;添加硅钙钾肥可以适当控制油菜体内的硝酸盐含量,增加可食用性,也可以明显提高油菜的Vc和可溶性糖含量,基于产量和品质的考虑,适宜添加量为1 800kg/hm2。
Addition of trace elements is an effective measure to increase the yield of vegetables, meanwhile it can also affect the quality of vegetables. Effects of Different Gradient Potash and Potash Fertilizers on Yield and Nutritional Quality of. The results showed that application of calcium silicate fertilizer with 600kg / hm2,1 200kg / hm2,1 800kg / hm2, 2,400kg / hm2, 3,000kg / hm2 could increase yield by 31.66%, 32.90%, 34.57%, 33.77% and 33.84% The calcium silicate and potassium fertilizer can properly control the nitrate content in the rape and increase the edible property, and can obviously increase the Vc and the soluble sugar content of the rape. Based on the yield and the quality, the suitable adding amount is 1 800kg / hm2.
