Eggplant belongs to the annual plant of the solanaceous genus, with many shapes, common oval, round, pear-shaped, etc., the color mainly includes purple black, purple, light green, etc., which are cultivated all over China. As a home-cooked dish, eggplant is a popular vegetable type. Of course, when we grow eggplant, we still need some cultivation skills.
< h1 class="pgc-h-arrow-right" > environmental requirements</h1>
Eggplant is not hardy in temperature, and the suitable temperature range for the entire growth period is 22 to 30 °C, and flowering below 20 °C is generally inhibited; when it is lower than 11 °C or above 40 °C, it stops growing.
Eggplant is a light-loving crop, with weak light or short light hours, reduced photosynthetic capacity, weak plant growth, increased short-column flowers, and poor fruit coloring, affecting the commodity value of eggplant.
Eggplant is drought tolerant and not flood tolerant, under normal circumstances, the maximum water holding capacity in the soil field is 70 to 80%, and the relative humidity is controlled by 70 to 80%.
Eggplant has strong adaptability to soil, and can grow normally on sandy soil, loam soil or clay soil, but it is advisable to choose soil with good drainage and irrigation conditions, deep soil layer, high organic matter content and good air permeability, and the soil pH is 5.8 to 7.3.

<h1 class = "pgc-h-arrow-right" > third, pest control</h1>
1. Physical prevention and control
Insect control net: For aphids, leafminer flies, beet nocturnal moths, cotton bollworms, whiteflies and other pests, to prevent them from entering the shed hazard, it is advisable to choose a silver gray insect net of 40 purposes. Tips: Cover directly on the skeleton of the greenhouse or build a horizontal trellis, then cover.
Silver gray film: hanging in the shed or covering the outside of the shed with silver gray film strips, which can drive away aphids, planthoppers and so on.
Hanging swatches: Yellow sticky insect plates are used to trap pests such as aphids and leafminer flies.
Hanging method: Hang 10 to 15 cm above the plant, and place 30 to 40 pieces evenly per acre.
Insecticidal lamps: Booby traps beet moths, small cabbage moths, vegetable borers and other pests, every 2 to 3 hectares to hang 1 insecticidal lamp, the height from the ground is 1.5 to 2 meters.
