GT-S叶面肥对小白菜产量及品质的影响

Effect of GT-S Foliar Fertilizers into Surface of Leaves on Yield and Quality of Chinese Cabbage

为了提高产品的市场竞争力,促进农业的可持续发展,采用田间小区试验的方法,研究了喷施GT-S叶面肥对小白菜产量及品质的影响。结果表明:喷施GT-S叶面肥可以显著提高小白菜的植株高度、叶片宽度、叶绿素含量及产量。同时,喷施GT-S叶面肥均显著降低了小白菜硝酸盐的含量,最高降幅达45.37%;且显著提高了小白菜可溶性糖、可溶性蛋白及游离氨基酸含量,最高增幅分别为37.33%、47.36%、18.20%。喷施GT-S叶面肥是提高小白菜产量及改善品质较为有效的方法之一。

In order to improve the market competitiveness of agricultural products,promote sustainable agricultural development,through field plot experiments,the influence of spraying GT-S foliar fertilizer on yield and quality of Chinese cabbage was studied.The results showed that spraying GTS foliar fertilizer obviously enhanced the plant height,leaf width,chlorophyll content and yield of Chinese cabbage.Meanwhile,spraying GTS foliar fertilizer significantly reduced the nitrate content with the maximum drop of 45.37%.Moreover,it markedly improved the content of soluble sugar,soluble protein and free amino acid in Chinese cabbage with the maximum augment of 37.33%,47.36%and 18.20%respectively.Taken together,spraying GTS foliar fertilizer is one of the effective methods of enhancing yield,reducing the nitrate content and improving quality of Chinese cabbage.
