| Abstract: | It is shown by investigating and comprehensive evaluating of question and fertilization condition of protectorate vegetable in Shouguang county: The content of fertilizer is higher in protectorate vegetable than in field in Shouguang, but it is very unbalance. Because of applying too large rate of chemical nitrogen and phosphorus fertilizer, such as environmental pollution, soil made vegetable quality and the input/output ratio come down, and too high content of NO - 3 in vegetables. The rate of K fertilizer is too low. Salinization, soil acidify, lack of middle and microelements. That In view of those problems, the author gives several rationalization proposals about vegetable fertilizing finally. |
