| The aboveground dry biomass of grape includes the growth of shoot dry weight and the growth of fruit, in which the growth of fruit can be obtained by the measured yield, while the shoot dry weight is rather difficult to measure. The modified Logistic model, Richards model, Hoerl model, vapor pressure model and Gauss model were adopted to simulate the dry matter accumulation process of grape shoot, and the results were testified by the measured data. As a result, the modified Logistic model was chosen to describe the growth process of shoot dry weight of grape. On this basis, with the objective of maximum growth amount of aboveground dry matter, the suitable irrigation quota of grape was 430～490 m3·666.7m-2, in addition to the pier burying water. |
