Select the bulb without wounds, bud tip well preserved taro seed, taro sowing is generally carried out after the final frost, pay attention to the early sowing is easy to cause rotten seeds. Before sowing the taro out in the sun in the sun 1-2 days, so that the late taro seedlings are more neat, in the germination pay attention to moisturizing, control the temperature at about 18-20 ℃. Planting land for furrowing fertilizer, 2500 kg of farmyard manure per acre, 30 kg of compound fertilizer can be applied.
A taro cultivation technology and management
1, choose the bulb without wounds, bud tip preservation is intact, the weight of 50 grams or so, the shape of the taro seed for the round ball. General sowing taro in the final frost, many areas are in the middle and late April when sowing, pay attention to too early for sowing is easy to cause rotten seeds.
2, before sowing sun seed germination, so that the late taro seedlings are more neat, the taro out of the sun in the sun 1-2 days can be. In the germination of moisturizing is very critical, the temperature control in 18-20 ℃ is better, about 15 days after the buds will be sprouted, in the buds grow 1 cm or so when you can sow the seeds.
3, planted land for ditching and fertilization, general ditch spacing of 1 meter, about 30 cm deep, 40-50 cm wide, first in the ditch fertilization, planting an acre of taro with 2500 kg of farmyard manure, compound fertilizer 30 kg can be.
4, according to taro varieties, generally more children taro row spacing of 65 cm, plant spacing of 35 cm or so; kui taro spacing of 60 cm. Covered with fine soil after planting, as long as the buds are slightly exposed. If the water taro planting, to be planted when the seedling height of 25 cm, and irrigation of about 5 cm.
5, taro in the seedling period to less fertilizer, and shallow plowing, and then every half a month according to the plowing soil to fertilizer, such as taro above ground part of the growth of very vigorous time can be fertilizer, per acre can be 10-15 kg of urea, 20 kg of compound fertilizer, *** need to be fertilized 3-4 times in the late taro growth to stop the fertilizer.
6, taro planting to keep the soil moist in the early stage, the growth period and bulb formation to do a good job of watering management, keep the water sufficient. Water taro, then the water surface should be maintained at about 3-5 cm, in July-August when the temperature is relatively high, water vapor evaporation, this time the water level can be deepened by about 10-15 cm, shallow water at the end of August, September after gradually draining the water, so that is conducive to harvesting.
7, in the taro above ground growth rapidly, bulb expansion, son of taro as well as grandson taro formation time to cultivate soil, *** cultivate soil 3 times, this can promote taro root.
8, taro diseases are mainly taro rot disease, epidemic, in the early stages of the disease can be sprayed with 50% carbendazim 600 times liquid, or 75% Chlorothalonil wettable powder 700 times liquid for prevention and control.
Second, when taro planting appropriate
1, taro is generally planted in the spring 1-3 months, the specific planting time according to the local temperature, humidity.
2, taro maturity when some of the leaves will turn yellow, this time to stop the water supply, in the harvest first dig out the soil on one side, and then grasp the stem and leaves to pull inward, so that the harvest can reduce taro damage.
3, leave the seed buds to wait for full maturity to harvest, 6-7 days before harvesting at the base of the petiole 7-10 cm cut off the ground, after the wound is dry and healed to harvest.
4, taro does not tolerate low temperatures, so fresh taro can not be placed in the refrigerator, in temperatures below 7 ℃, to be stored in a warmer place indoors, to prevent rotting due to frostbite.
