为推广应用稻草型生物有机肥,采用田间小区试验研究了稻草型生物有机肥对莴苣根系特性、产量和品质的影响。结果表明:稻草型生物有机肥增强了莴苣的根系活力,提高了莴苣根系的硝酸还原酶活性,显著提高了莴苣的产量,增加了莴苣茎叶中可溶性糖、维生素C的含量,降低了莴苣茎叶中硝酸盐、亚硝酸盐及粗纤维的含量。

In order to popularize and apply rice straw based bio-organic fertilizers,the field plot experiments were conducted to study the effects of rice straw based bio-organic fertilizers on the root characteristics,yield and quality of lettuce.The result indicated that using appropriate rice straw based bio-organic fertilizers can promote the root vigor of lettuce,the nitrate reductase activity of lettuce root,the yield of lettuce,and the contents of vitamin C and soluble sugar in stem and leaves of lettuce,while the contents of nitrate...
