Taro planting methods and management:
1, choose seed sowing
The seed taro should choose bulb without wounds, the tip of the terminal bud is well-preserved, weighing up to 50g or so, the shape of the round ball. General sowing taro, are carried out after the final frost, many areas are sown in mid- to late April, if the seeds are sown too early, it is easy to cause rotten seeds.
2, sun seed germination
In order to late taro can be neat seedling, we will sun seed germination. Taro out, placed in the sun 1-2 days, in the germination, moisturizing is very critical, the temperature is good to control at 18-20 ℃, about 15 days after the buds, buds about 1 cm long can be sown.
3, ditching
Fertilizer ditching, generally ditch row spacing of 1 meter, 30 cm deep, 40-50 cm wide, first in the ditch fertilization, an acre of taro planting can be applied to 2500 kg of farmyard manure, compound fertilizer can be 30 kg.
4, planting
According to taro varieties, the general multi-son taro row spacing 65 cm, spacing 35 cm or so, kui taro spacing 60 cm. Covered after planting, required slightly exposed buds. If the water taro planting, in the seedling height of 25 cm, planting, and irrigation of about 5 cm.
5, fertilizer
Taro seedling less fertilizer, and shallow plowing, and then every half a month, according to the cultivation of plowing to fertilizer, until the taro on the part of the growth of the very vigorous, can be fertilizer, an acre of taro planting can be applied to the urea 10-15 kg, 20 kg of compound fertilizer, the total **** need to fertilize 3-4 times. Taro growth late stop fertilizer.
6, irrigation
Taro planting, the first stage to keep the soil moist, the growth period and the bulb formation period must do a good job of watering management, to keep the water sufficient, but if you're in the ditch irrigation, the water surface from the bed surface to keep in the 5-10 cm can be.
Water taro, then the water surface should be maintained at about 3-5 cm. July-August temperature is high, water vapor evaporation, so the water level can be deepened by about 10-15 cm. shallow water at the end of August, after September gradually drain the water, conducive to harvesting.
7, cultivation
As the saying goes, taro is not cultivated, equal to not planted. Mainly to promote taro rooting. In taro above ground growth rapidly, bulb expansion, sub taro as well as grandson taro formation, cultivation, **** 3 times. The total thickness is generally controlled at 30 centimeters. Growers cultivate into a ridge after the latter 1 time of heavy fertilizer.
8, disease control
Diseases are mainly taro rot disease, epidemic disease two. The early stage of the disease can be sprayed 50% carbendazim 600 times liquid, or 75% Chlorothalonil wettable powder 700 times liquid for prevention and control.
9, harvesting and seed saving
Many regions harvest taro, in the frost before and after the leaf yellow root withered for maturity, it can be harvested. And for the seed taro, it must be fully mature before harvesting, harvesting the ground part of the first cut, to be healed, choose to harvest on a sunny day, after harvesting a good first do not rush to storage, first in the sun for a day of drying, the good storage temperature of 10-15 ℃, pay attention to can not be frozen.
