Cultivation techniques for high yield of taro with low cost and high benefit

Taro, which combines vegetables, grain and medicinal diet, is very popular in the domestic market recently, and is exported to Japan, South Korea and Southeast Asia in large quantities. Taro is a perennial herbaceous leguminous plant, the leaves are like lotus leaves, the roots are small, flat-bottomed and round, and the diseases, insects and weeds of taro are few, fertilizer, medicine and labor are very few, and it is easy to grow low-input and high-income projects.

Taro

1. Sow seeds at the right time. The suitable temperature for the growth of taro is between 15-35 ℃. Taro seedlings are raised when the air temperature is below 15 ℃, and transplanting is carried out when the temperature is stable above 15 ℃. The planting period of taro in Dabie Mountains in southwestern Anhui is in the middle of April, and the sprouting stage and knot expansion stage are from mid-June to late September when there is sufficient light and heat.

2. Reasonable close planting. The planting of taro is in the fields with sufficient light, good ventilation, high content of organic matter, convenient drainage and irrigation and unsheltered surrounding. A year ago, the soil was turned deep once to make a border 2 meters wide. Taro planting holes were dug on both sides and in the middle of the border, with 3 rows each, with a depth of 20 cm and a plant spacing of 50-60 cm. Before sowing, a little compound fertilizer and mature organic fertilizer were applied at the bottom of the hole, covered with thin soil as fertilizer layer and isolated seeds, and one young taro seedlings were sown in each hole.

3. Field management. ⑴ fertilization: less fertilizer is needed for taro. Topdressing 1-2 times in the growth stage, opening holes in the middle of two taro plants during the expansion period, applying 25 grams of compound fertilizer and 15 grams of urea, covering the soil and watering. ⑵ water control: taro like moisture, afraid of drought, growth period of taro avoid stagnant water, at this time, Rain Water too much, should be trenched as soon as possible drainage. Taro growth is exuberant, need a lot of water, and sometimes meet high temperature and drought, but daily irrigation, night row. The mature stage is dominated by soil moisture. ⑶ soil cultivation: the important measure to improve the yield of taro is to cultivate soil. From May to June, the growth of taro is exuberant and taro begins to bear fruit, so we should shovel ditch soil or cover it in time. ⑷ grass and pest control: after sowing and before emergence, the taro was sprayed with Acetochlor or Duer herbicide once, and weeding was once before the stem and leaf were sealed, and then the stem and leaf were covered, and the weeds could not survive. Taro pests are very few, May-June when the leaves are tender, if there are cabbage insects, dimethoate can be used to control.

4. Harvest and storage. In the middle of October, its stems and leaves withered naturally, so it can be harvested and put on the market; it is appropriate to dig up taro a few days before the first frost in early November. After harvesting, a small number of taro can be bagged and stored between indoor rice bran; the quantity can be dug cellar in the sunrise and sheltered highland, put 1 layer of dry straw and 1 layer of taro, seal the hole after storage, cover the soil is convex, cover grass waterproof.
