Do you know what issues should be paid attention to during the planting of areca taro?

Generally, attention should be paid to land selection and seed selection.

Betel nut taro should be planted on loam or sandy loam with deep soil, fertile and loose soil, and easy drainage and irrigation. Before planting, the soil should be deeply plowed and bleached, and quicklime should be sprayed at 900 ~ 1500kg/hm2 for soil improvement and disinfection. Avoid continuous cropping of betel nut and taro. If conditions permit, rotate once a year and at most every two years. It is recommended not to rotate crops within three years, otherwise the yield will be reduced and the cost of pest control will increase. The choice of seed taro requires no insect damage, no damage, no rot, full terminal buds, and uniform size. If the seed taro is larger, it will be beneficial to the growth of Areca taro, increase the weight of the mother taro, and significantly increase the yield. Try to use 70 to 100 grams of seed taro as seed taro.

1. Seedbed preparation

Plant in a single row, with high sides and deep trenches, side width 100 cm, height 30 cm, and trench width 30 cm. Dig a hole on the side, the hole is as deep as the bottom of the plow, and the holes are 50 cm apart. Plant about 1,200 plants per acre. Dry for 1-2 days before sowing, and then treat with 0.1% potassium permanganate or 50% fluconazole. Soak the wet powder 500 times, sterilize it for 10-20 minutes, take it out and dry it for later use. Planting is usually done in the first ten days of March. Plant one seed in each hole, spread the seeds flat on the bottom of the hole, and cover them with about 2 cm of organic fertilizer or fine soil. Cover with plastic film after planting and pile soil around the plastic film. Compared with open field cultivation, covered seedlings emerged significantly earlier, the number of leaves per plant increased by 1.3 to 1.9, the yield of mother taro increased by 11.02%, and that of seed taro increased by 7.17%.

2. Water and fertilizer management

Betel nut taro has a long growth period, tall plants, high yield, and requires a large amount of fertilizer. Apply calcium, magnesium and phosphorus at 1500 kg/hm2 and 45% ternary compound fertilizer at 375 kg/hm2 as base fertilizer. 7-10 days after emergence, apply 300 kg/hm2 of 45% ternary compound fertilizer. About 30 days after the first top dressing, the second top dressing is combined with soil cultivation and stump stacking. For acupoint application, use 45% ternary compound fertilizer 375 kg/hm2 and urea 75 kg/hm2. The third top dressing should be applied 30 to 35 days after the second top dressing, and 375 kg/hm2 of high-potassium ternary compound fertilizer should be applied per acre. Betel nut taro likes moisture and is afraid of drought. The soil should be kept moist throughout the growing season. Keep the soil moist after planting and before the 5-leaf stage to prevent water accumulation in the pit. After the 6-leaf stage, plant growth accelerates, temperature rises, and water demand increases. Keep water in side ditches 10 to 15 cm deep and drain them about 15 days before harvest.

The above are the precautions in the process of planting taro for your reference and study. I hope it will be helpful to everyone.
