| Abstract: | Thirty-six soil samples of different years of continuous cropping of protected cultivation and controls in the near open ground were collected and their nutrients determined in this study. The results showed that the contents of organic matter, total N, total P, total K and alkali-hydrolysable N, available P and available K in the soil of continuous cropping of protected cultivation of tomato were obviously higher. |
