Planting taro mainly consists of the following four steps:

One, choose the ground sowing

Since taro generally does not bloom and bear seeds, it can only be reproduced by underground tubers. In March of each year, when the spring flowers bloom, choose a uniform size, skin intact, no potential pests and diseases of the tuber seeding. You can plant seedlings first and then transplant, or direct seeding. The choice of seed taro, it is best to choose the best varieties suitable for local climatic conditions and planting environment. The seed taro can not be too big, not too small. Too large seed taro contains more nutrients, easy to sprout after cultivation, resulting in nutrient loss. If cut into small pieces, it is easy to get infected with diseases. Seed taro is too small, less nutrients, after the seedlings, thin seedlings, disease seedlings are easy to form.

Two, field fertilizer management

The growth of taro can not be separated from the water, plots to choose convenient drainage and irrigation of low-lying or swampy land. For dryland planting taro, be sure to pick a high box deep ditch cultivation, easy irrigation and fertilization. Taro seedling three months after the time is the long seedling period, this stage, taro on the fertilizer requirements are not too much, only need to water, keep the field moist, according to the taro seedling growth of a small amount of nitrogen fertilizer. Three months later, taro underground stem block began to grow son taro or grandson taro, this time need a lot of nutrients, began to chase fertilizer. Fertilizer to nitrogen and potash fertilizer, and supplemented with appropriate amount of phosphorus fertilizer, so that fertilization is conducive to taro into the expansion period. When entering the expansion period, you also need to fertilize once, in order to ensure that the supply of nutrients is sufficient. Two fertilizer should be with watering, and soil cultivation.

Three, pest control

The main pests of taro in the growing period are epidemics and oblique moths. The prevention and control of epidemics is mainly in the choice of seed field fertilizer management efforts, seed taro must be selected disease-free varieties, and to soak the seed treatment. Field watering in the seedling period to keep moist, in the middle and late to interval sun field. The early stage of the disease in time to use drugs to prevent and control, and several kinds of pesticides used alternately, the interval of seven days with a drug. The discovery of slash moth, to use pesticide spray control, morning and evening with the best results. Spraying, due to taro leaves large, the front and back of the leaves should be sprayed, so that the liquid completely contact pests.

Four, timely digging

Taro harvest is generally harvested in the fall before the frost is completed, premature harvest, taro did not grow and develop to completion, affecting the yield, when the edge of the leaf blade appeared withered, you can cut off the taro poles, take time to dig. High temperature in the fall, do not cut the pole too early, otherwise taro will be the second germination, affecting the quality.
