Black soil and alluvial soil with deep soil layer, fertile soil, high organic matter content, convenient irrigation and drainage, good water and fertilizer conservation performance and slightly higher water content should be selected as taro land.

2. Soil preparation and fertilization

Remove the stubble, turn it over to a depth of 30 cm, and then ridge it with a ridge distance of 70 cm wide. 75 cubic meters of agricultural fertilizer, 200 kilograms of chemical fertilizer nitrogen, 00 kilograms of phosphorus and 0/50 kilograms of potassium/kloc were applied to the ridge people.

3. Bud mutation breeding and planting

In order to prolong the growth period of taro, it is necessary to accelerate germination with fire resistance or plastic arch shed 20 days before sowing. When the taro buds grow to 4-5 cm, they can be taken off the kang (bed) and planted after cutting. Sowing depth is 4-5cm, and plant spacing is 35cm. When covering the soil, it is advisable to expose the seeds slightly.

4. Tian Tuan management

① Topdressing. Taro is a fertilizer-loving crop with a long growth period. Therefore, topdressing should be advocated when nitrogen, phosphorus and potassium are applied together, and the number of topdressing should be determined according to the growth of taro, generally topdressing is 2-3 times in a lifetime.

② water. Taro is a water-loving crop. During the period from emergence to harvest, the soil must be kept moist, and the soil water content is slightly higher than that of ordinary dry fields. In case of drought, water it in time, and drain it in time in case of accumulated water.

③ intertillage and cultivate soil. Weed and loosen the soil in time at seedling stage to raise ground temperature and promote growth. At the end of the seedling stage, people enter the vigorous growth period and cultivate the soil every 10 day. Its main purpose is to inhibit the germination of seeds and offspring and promote the growth of underground taro, which is the key measure of taro cultivation. Only by pressing the offspring buds can the yield and quality be improved.

④ Disease control. Agricultural control should be the main measures, such as crop rotation, elimination of inferior taro seeds and selection of disease-free taro seeds. Reduce the occurrence of diseases. Various fungicides can be selected for chemical control and foliar spraying at different growth stages to prevent soft rot and epidemic diseases.

harvest

In order to meet the needs of the growing period to the greatest extent, harvesting as late as possible can improve the yield and quality under the premise of not suffering from freezing damage.
