Four questions about pepper production

Q: What is the impact of continuous hot peppers? A: First, the disease is aggravated, such as virus disease ( mosaic disease), epidemic diseases, etc., causing a large number of dead seedlings; Second, the composition of inorganic nutrients in the soil changes, often the lack of calcium, magnesium, boron, aluminum, manganese, iron, etc. Resulting yellow leaf, mosaic, leaf rolling, falling flower, fruit drop, low yield; Third, continuous cropping will reduce soil organic matter content, soil porosity decreased, buffer capacity decreased, root development blocked, affecting yield and quality. Q: How to overcome the dangers of continuous cropping of hot peppers? A: First, increase organic fertilizer, enhance the soil buffer capacity; Second, deep-turning the soil; Third, deep-rooted fertilizer, top-dressing limit; Fourth, to promote outside the top dressing; Fifth, the ground covered with straw. Q: After the flood (heavy rain), the death of pepper seedlings is a thing of the past? Answer: From July to August, after the flooding or heavy rain, the pepper fields often appear dead. If the irrigation volume is large, the number of flooding irrigation is large, or the rainfall is heavy, the rainfall is heavy, and the disease is heavy. At high temperatures, the flood death rate can reach 100%, which is mainly the result of an outbreak of pepper disease. To prevent this from happening, one is to strictly level the land and avoid low-lying plots of water in the fields; ridge cultivation, plant length on ridges, application of microbial fertilizers (such as biological nitrogen fixation, biological potassium fertilizers, etc.), inhibition of pathogenic microorganisms, and stimulation of root growth , improve soil permeability. The second is reasonable watering, water control, shallow water irrigation, should not flood irrigation, string water dip irrigation or drainage water runoff. The third is the combination of irrigation, the application of copper sulfate irrigation roots, acres with 1-1.5 kg of copper sulfate and fine soil slightly spread the ground, and then light irrigation. The fourth is to spray 5% of the poisonous copper 1000 times or 64% of the poisonous aluminum copper 250 times, etc. to control (or use aluminum phosphonium manganese zinc, metalaxyl manganese zinc, agricultural resistance 120). Q: Can chili pepper mosaic prevent it? A: The “chicken mosaic disease” of pepper is commonly known by the public. Its scientific name is “virus disease” and it is mainly transmitted through insect-borne insects such as locusts, which cause extensive damage. According to the current practice of cultivars, system control measures should be taken: first, deep-turn balanced fertilization; second, actively promote the interplanting of wheat, pepper, and corn; third, early planting in an appropriate period; fourth, insecticide spraying in time; Fertilizer compound solution, that is, from the colonization to the fruit before the maturity of sprayed 0.6% mifepristone, 0.6% potassium dihydrogen phosphate, 0.1% zinc sulfate, magnesium sulfate, ferrous sulfate and sodium sulfite and other compound liquid. But the most fundamental measure is still rotation. China Agricultural Network Editor
