摘要
以3个小西瓜品种为试材,采用田间小区试验,研究其露地栽培的适应性。结果表明:"京欣"在各时期的叶绿素含量最高;其净光合速率比"黑美人"和"京秀"分别提高15.36%和25.09%,荧光参数Fv/Fm、Fv/Fo也高于"黑美人"和"京秀",水分利用效率较二者分别提高14.31%和83.38%,产量和品质均优于二者,表现出很强的适应性,值得在生产上推广。
The culture adaptability of mini-watermelon varieties were compared by using field experiments. The results showed that Jingxin was superior than others in chlorophyll contents in different stages;Compared with Heimeiren and Jingxiu,the net photosynthetic rate increased 15. 36%, 25. 09%, respectively; Fv/Fm and Fv/Fo were increased, too. Compared with Hemeiren and Jingxiu, water use efficiency increased 14. 31%, 83. 38%, respectively, yield and quality were better than two, showing strong adaptability, it＇s worth promoting in production.
