Timely topdressing: Because the peppers have more fruit and are harvested many times, the fertilizer needs to be larger in the middle and later stages, so it is necessary to carry out topdressing. The basic principle of pepper topdressing is â€œcontrolling nitrogen, stabilizing phosphorus and supplementing potassium with potassiumâ€. The land with good ground strength and sufficient bottom fertilizer can be combined with watering, and the water is fertilized (flux fertilizer) 4 kg or urea 8 kg plus sulfuric acid. Potassium 5 kg; the bottom fertilizer is not applied with organic fertilizer, the top dressing is insufficient, the plot with premature aging, after each picking, combined with watering, applying 6 kg of water soluble fertilizer or 10 kg of urea plus 6 kg of potassium sulfate, continuously used 2~3 Times. When the plants are flowering in large quantities and the number of fruits is increased, root top dressing can be used, 0.1% urea is added with 0.2%~0.3% potassium dihydrogen phosphate and other micro-fertilizers. With 0.2% potassium dihydrogen phosphate or green Fenwick 50 g to 50 kg water foliar spray, the yield can be significantly improved.
Foliar spray fertilizer to prevent high temperature: suitable growth temperature of pepper is 25 Â° C ~ 30 Â° C, temperature above 35 Â° C is not conducive to the growth and development of pepper, affecting the flowering results of pepper. At present, it has entered the hot season, and the high temperature is inevitable. Effective measures should be taken in time to prevent the high temperature from harming the pepper. 1. Spray foliar fertilizer. By spraying foliar fertilizer, enhancing nutrition, improving plant resistance, and improving the ability of pepper to withstand high temperature, foliar spray of alginic acid, 1% aqueous solution of superphosphate or 1%~2% potassium nitrate aqueous solution, 7~10 days Spray once, a total of 2 to 3 times, can increase the weight of single fruit, make the color beautiful, reduce the occurrence of sunburn in the late stage of pepper, improve the grade and income of pepper. 2. Supplement trace elements. Foliar application of 1500 times of zinc sulfate, chromium combined with high calcium, Guoguang high potassium and other micro-fertilizers to improve the heat resistance of pepper and prevent the occurrence of pepper lobular disease.
Late fattening: Although the peak of pepper growth has passed the peak of fertilizer demand, there are also needs. Pay attention to the principle of applying a small amount of fertilization several times. It is necessary to combine the watering mu to apply 15 kg of special compound fertilizer for pepper. The top dressing should not be applied to the leaves and near the roots to prevent the occurrence of fertilizer burning. In the plots where premature aging has occurred, in addition to the anti-aging fertilizer, it is also necessary to use root dressing in combination with spraying and pest control. It can use 0.1% urea solution, 0.2%~0.3% potassium dihydrogen phosphate solution and other micro-fertilizers. Fertilizer can quickly improve the condition of premature aging.
