通过对９种蔬菜研究表明，蔬菜各器官养分含量高而转移率低，属营养非完全转移型作物；蔬菜需肥量大，比谷类作物约高出１／３；蔬菜的钾氮吸收比高（大于１～１．５），而磷氮吸收比低（小于０．３）；每公顷产４５～７５ｔ蔬菜，约需Ｎ３００～４５０ｋｇ，Ｐ２Ｏ５１０５～２２５ｋｇ，Ｋ２Ｏ１０５～２１０ｋｇ，１ｋｇＫ２Ｏ可增产番茄２６．１～１４１．３ｋｇ，甘蓝１１．２～５３．１ｋｇ，黄瓜５．８～８６．９ｋｇ，甜菜１０ｋｇ，尖辣椒１１．４ｋｇ
The study on nine kinds of vegetables showed that the organs of vegetables had high nutrient content and low transfer rate, which was a non-fully-transfered nutrient crop. The vegetable required a large amount of fertilizer, about 1/3 higher than that of cereals. The potassium-nitrogen absorption ratio of vegetables was high (More than 1 ~ 1.5), while the phosphorus and nitrogen absorption ratio is low (less than 0.3); 45 ~ 75t vegetable per hectare takes about N300 ~ 450kg, P2O5105 ~ 225kg, K2O105 ~ 210kg, 1kgK2O can increase tomato26. 1 to 141.3 kg, 11.2 to 53.1 kg of cabbage, 5.8 to 86.9 kg of cucumber, 10 kg of beet, 11.4 kg of spicy pepper
