Cassava farming methods
As an important cash crop in tropical areas, cassava has become the new favorite of garden planting due to its drought resistance and poverty tolerance. Mastering full-cycle management skills from soil improvement to harvesting can increase root yield by more than 30%. This article will systematically explain the key points of family planting. The soil improvement plan for planting environment management selects loose and breathable slightly acidic red soil. Before planting, it is deeply plowed by 40cm and mixed with murky leaf soil. When loosening soil every season, plant ash can be applied to adjust the PH value and replenish potassium. It is recommended to use a mixed substrate of peat soil: perlite =3:1 for potted plants. Light and temperature regulation Direct light for 6 hours per day ensures that the stems are thick, and a 30% sunshade net is built in summer to avoid leaf burns. The overwintering temperature needs to be kept above 10℃. In northern regions, it is recommended to adopt dual insulation measures of plastic film mulching + arch shed. Key points of water and fertilizer management Scientific irrigation rhythm Use atomized spraying to keep the topsoil moist within 7 days after transplanting, and change to the "see dry and see wet" mode after root development. In the rainy season, circular drainage ditches need to be excavated to ensure that the soil moisture does not exceed 65%. Nutrient supply plan Apply fermented soybean cake water (diluted 1:50) every month during the growing period, and add calcium-magnesium phosphate fertilizer during the bud appearing period. Nitrogen fertilizer was stopped 45 days before harvest and potassium dihydrogen phosphate was sprayed on leaf to promote starch accumulation. Physical preventive measures in the pest and disease control system regularly remove surrounding weeds to reduce insect sources, and set up yellow sticky insect boards to trap whiteflies. When red spiders are discovered, they are immediately sprayed with a mixture of chili water + detergent, and snails can be isolated and protected by a quicklime ring. Biological control technology introduces predatory mites to control the red spider population, and applies Beauveria bassiana powder before the rainy season to prevent grub. It is recommended to use botanical pesticides such as azadirachtin, and the safety interval is controlled within 7 days.
By accurately controlling the light intensity and the temperature difference between day and night, and combining with the scientific ratio of organic fertilizers and trace elements, the yield of cassava per plant can reach 15-20 kilograms. It is recommended to rotate legumes every 2 years to maintain soil fertility. By mastering these core skills, harvesting can be achieved in all seasons.
