High quality taro planting methods

The video shows the planting methods of taro. To grow high-quality taro, it is necessary to grasp the three core links of seed selection and land preparation, field management, and harvesting and stubble retention. The steps are as follows: First, seed selection and land preparation. Select high-quality taro corms with plump buds and no disease spots, soak them in carbendazim solution for disinfection, and then germinate them for later use. Choose deep, well-drained, slightly acidic and fertile loam soil, and avoid solanaceous and zingiberaceous crops as previous crops. After deep ploughing, apply sufficient base fertilizer such as decomposed organic fertilizer, superphosphate and potassium sulfate, then ridge and harrow the soil to ensure uniform soil fertility and good drainage. Second, field management. Plant the germinated taro corms at a reasonable plant and row spacing, cover them with soil, compact the soil, and water thoroughly with rooting water. Timely check and replenish seedlings during the seedling stage, and remove weak and diseased seedlings; cultivate and earth up regularly 3 times during the growth period to promote the expansion of daughter taro and avoid the tubers from being exposed and turning green. For water and fertilizer management, follow the principle of "light application in the early stage and heavy application in the expansion stage": apply less nitrogen fertilizer in the seedling stage, focus on increasing potassium fertilizer in the corm expansion stage, and avoid using potassium chloride; use drip irrigation to keep moisture in dry weather, and timely dredge ditches for drainage in rainy seasons to strictly prevent root rot caused by waterlogging. Adopt physical and biological control methods to prevent and control diseases and insect pests such as blight and Spodoptera litura. Finally, harvesting and stubble retention. When the lower leaves of the plant turn yellow and the corm epidermis becomes hard, harvest on a sunny day and dig carefully with a hoe to avoid damaging the tubers. After harvesting, clean up the residual plants in the field to reduce the residue of diseases and insect pests and facilitate subsequent farming.
