Improve the fruit setting rate of pepper

When the high-temperature pepper color often appears difficult to set fruit, fruit drop is serious, resulting in imbalance of vegetative growth and reproductive growth, plants prosperous (people commonly known as Wang Kezi). Some farmers believe that the control of water and fertilizer can control the growth, but the result is that the plants are getting more and more prosperous, and fruit set-up is getting more and more difficult. The reason is that this period is in a critical period of vegetative growth and reproductive growth transition. Lack of water and lack of fertilizer can easily cause nutrient growth to vegetative growth, and reproductive growth and nutritional insufficiency can result in increased fruit setting rate. To increase the rate of fruit set, the following measures can be taken:

1. Cool down. Temperatures higher than 32Â°C will cause drop and fruit drop, which will seriously affect the fruit setting rate of the color pepper. Therefore, in the high temperature at noon to strengthen the ventilation, and cover the shade net, or spray mud to reduce the temperature.

2. Regulate humidity. Appropriate air humidity is very important for normal fertilization. In general, suitable air humidity is 70% to 80%. During the blooming period, if the humidity is too low, the sprayer can be used to spray fresh water on the leaves to increase the humidity of the air. If the humidity is too high, it is necessary to ventilate and dehumidify the leaves.

3. Reasonable fertilization. Boron and phosphorus play an important role in promoting flower bud differentiation and improving fruit set. In flowering and fruit setting period, boron fertilizer can be sprayed with 600 times liquid borax or 1200 times sulphur leaf, spraying 300 times potassium dihydrogen phosphate solution to supplement the phosphate fertilizer. Potash fertilizer can improve drought resistance and heat resistance of plants. In addition, calcium fertilizer (spraying 0.5% of high-calcium foliar fertilizer or 5 to 8 kg/mu of calcium nitrate with water) is applied at the peak of the results to enhance plant resistance, improve pollination performance, and improve fruit quality. Quality, prevention of physiological diseases such as umbilical rot, sunburn, and bud blight have an important role. The four-door peppercorns must be flushed with a certain amount of high-nitrogen fertilizer before the size of the walnuts, strong tree roots, followed by high potassium fertilizer. In addition, at around 9:00 am every day, the crane wire is hit with a bamboo pole and the residual flower is shaken off to prevent the occurrence of diseases such as gray mold and pollination.

4. Apply growth regulators. When plants appear to grow in length, they can be sprayed with 750-fold booster and 30 ppm naphthalene acetic acid for control; spray 800-1000 times more for love and growth, and promote vegetative growth to reproductive growth and transformation; after planting, early fortification Fertilizer management, strong plants, when the appetite does not set fruit timely irrigation root or flush with fruit fruit Seoul or fruit fruit, usually 5 to 6 days after the application of a flowering fruit set, after the plant natural fruit set up, do not continue to apply fruit Seoul, normal management can be. If the plant grows again, it can be applied again.

5. Timely control of pests and diseases. Diseases and insect pests are also easy to cause difficulties in setting up peppers and should be sprayed and prevented. The use of effective cypermethrin, imidacloprid and other agents spray to prevent tobacco insects, cotton bollworm, aphids, spider mites and other pests; diseases are mainly virus disease, anthrax, soft rot, etc., should be promptly checked and found immediately after the prevention and treatment.
