| Abstract: | Nitrogen,phosphor and potassium are essential elements for vegetable fertilization.Pot and field experiments were conducted using root length to correlate with cumulative NPK absorption to establish a mathematical model by regression analysis.The results showed that,within a growth period,the curves of root length increase and NPK absorption of water spinach,lettuce,radish and Chinese cabbage were all in an S shape.Two root growth models for the water spinach and 30 NPK cumulative absorption models for the ... |
