According to the test, reasonable pruning of pepper plants can increase production by 15%-20%. This is because: each pepper usually has 4 large branches. After entering the summer, 8 branches are expanded on the 4 large branches. The branches are leafy and dense, and the phenomenon of “one litter bee†is formed. Therefore, the eight lateral branches are cut off to improve the ventilation and light transmission conditions of the plants, and the disease is alleviated, and the fertility is concentrated on the four large branches, so that the peppers have more results and large fruits, thereby increasing production and income.
Pruning time. Pruning is generally carried out from late July to mid-August. At this time, the first loquat fruit has been harvested, and the plant is in the resting stage when the temperature difference between day and night is not large, so the pruning effect is best.
Pruning area. At the top of the 4 large branches, cut 8 side branches in time.
Pruning method. Use sharper pruning scissors to cut the branches, and cut the mouth smoothly. Do not fold directly with your hands to avoid damage to the plants, causing pests or causing diseases. When pruning, the diseased pests are severely damaged, the drooping branches with excessive results in the early stage, and the broken branches that are improperly managed. The cut branches should be taken out of the garden for treatment, especially the pests and branches should not be left in the garden.
Cut management. After pepper pruning, it is necessary to strengthen field management, timely remove weeds and prevent pests and diseases. Apply 10 kg of urea per acre to promote growth and results. In case of drought, it should be combined with topdressing urea to timely water, prevent drought, and promote fertilizer efficiency. At the same time, 0.2% potassium dihydrogen phosphate foliar fertilizer can be sprayed, spray once every 7 days, even spray 2-3 times. The spraying time is best selected on cloudy or sunny evening, mainly spraying the back of pepper leaves. .

Grow lighting can be one of the most essential factors to successful plant production in a commercial greenhouse because grow lights help to lighten shady spots and propagation areas in the greenhouse. If you are growing tropical plants, you may need to set up grow lights if the plants don't get at least eight hours of sun each day. Most crops benefit from supplemental lighting, when increased growth and quality is converted into added revenue. We provide Growing Light and complete systems for your greenhouses.
