Embodiment 1
[0050] Taking greenhouse tomatoes as an example, a nutrient solution management method based on leaf length of the present invention is introduced in detail, which includes the following three steps:
[0051] Step 1, missing or not:
[0052] 1-1. The leaf positions of the characteristic leaves of the greenhouse tomato are as follows: before the fruiting of the greenhouse tomato, the inverted 3 leaves are the characteristic leaves; since the greenhouse tomato begins to bear fruit when the 8th or 9th leaf appears, after the greenhouse tomato bears fruit, the inverted 7 The leaf is the characteristic leaf; the standard leaf length is the characteristic leaf length calculated by the standard leaf length model, that is, the leaf length of the characteristic leaf under the condition of no water and fertilizer deficit;
[0053]1-2. Measure the leaf length of the characteristic leaf of the tomato in the greenhouse, and then input the temperature data in the greenhouse before the measu...
