酸雨不同喷淋方式对小白菜营养品质的影响

Effects of Different Acid Rain Spray Ways on Nutritional Quality of Pakchoi

以温室大棚内的小白菜为试供作物,通过配制不同pH值的混合型酸雨溶液,分别以不同喷淋方式模拟酸雨喷淋实验.结果表明:酸性较强的酸雨抑制小白菜中营养物质的形成;弱酸性酸雨促进小白菜中营养物质的形成;在不同喷淋方式中,单次喷淋量越多、喷淋时间间隔越长,对小白菜营养品质的影响越大.

The mixed simulated acid rain solutions at different pH levels were spayed on pakchoi in different spray ways within the greenhouse.The results show that strong acid rain inhibits the formation of the nutrients in the cabbage,while week acid rain increases the formation of the nutrients in the pakchoi.Among the three spay ways,more spray amounts and longer spray intervals in the single spray ways have the bigger influence on the quality of pakchoi nutrition.
