In recent days, rainfall has increased, even after the rain is not properly managed after the pepper, have a certain influence on the pepper, the main should do the following:
First, weeding and weeding, increasing plant ash, and reducing humidity and ventilation.
Through cultivating, breaking the soil compaction, improving soil ventilation, promoting the development of pepper roots, and creating a good soil environment for pepper growth. The cultivating time should be selected in the sunny high temperature period or before the high temperature, shallow near the root, deep between the rows, to avoid injury. After weeding, a large number of weeds lost water and died. At the same time, they have the function of soil disinfection and sterilization. In combination with cultivating grass ash, the first is to reduce soil moisture; the second is to increase soil nutrients.
Second, pruning, to prevent falling flowers and falling fruit
When pruning pepper, keep the trunk and 2-3 side branches, the lower axillary buds should be wiped off, and cut off the inner litchi, the old and sick branches, so that the inner pagoda is airy and transparent, leaving 2 leaves at the 3rd level branching and tipping, new The growing branches left 1 fruit and 2 leaves for sharpening, and the old diseased leaves were removed to promote the growth of the upper leaves and the elongation and enlargement of the fruits. At the same time, the soil was again used to promote new roots, and 2 urea and potassium dihydrogen phosphate fertilizers were sprayed.
Third, push the plants together to improve the ventilation and light conditions in the field
In the mature period of pepper, due to the dense plant growth, crisscross branches, and incomplete removal of weeds, or improper management, etc., directly affect the line when the pepper matures require good ventilation and light conditions. If we do not push the strains together to solve the problem of the group's shelters, especially the rain will continue to appear, Feng Feng received the victory of the fruit of fruitful, directly affect the quality of mature, causing major losses. Therefore, pushing the strains together is the key measure to promote the red ripeness of the peppers in rainy days. Push the plant to close together: Manually apply the pepper plant about 5 cm from the base of the stem, push it firmly to both sides, and apply the root to the foot firmly. But be gentle and try to prevent damage to plants and green peppers. While pushing the plants together, they can be combined to remove weeds, pick up green peppers, spotted peppers, and deformed peppers. Create a good ventilation and light conditions for chili.
IV. Disease Prevention
Diseases. Phytophthora blight is a devastating disease. In the event of rain or heavy rain, the disease quickly spreads and becomes a serious disaster.
(1), the main symptoms: leaf lesions were round or nearly round, the central dark brown, yellow-green edges, the fruit began to attack from the pedicle, lesions of water-immersed dark green, and later become soft rot. When the humidity is high, the leaves are soft rot and easily fall off, and a white mold layer grows on the fruits.
(2) Prevention: In the early stage of disease, timely use 58% metalaxyl MnZn WP 500 times or 64% antivirus 600 times or 50% Mancozeb WP 600 times, every 7-10 One day spray, spray 2-3 times, serious, spray every 5-7 days, spray 4-5 times.
