1. Appropriately planted. Eggplant has higher requirements for light, while eggplant leaves are large, dense and thick, and the extinction coefficient is particularly large, and the natural light is generally only 50% of the summer. The light in the greenhouse is only 50-70% of the natural world, and it is clearly presented. Strong and weak. Therefore, greenhouse cultivation of eggplant must not adopt the plant spacing configuration of open field cultivation, and must be properly planted; and it can not be used as a natural branching method in open field cultivation, and artificial pruning must be carried out.
2. Strict pruning. Generally, the method of double dry pruning is adopted. In the early stage of planting, it is possible to use interlaced 2 dry, interlaced 3 dry, and when 3 dry affects the light transmission between the rows, it is resolutely restored to 2 dry pruning. Timely remove the bottom blade of the yellowing aging.
3, try not to cover the PVC film.
