Encroaching continuous cropping, continuous cropping affecting root growth and tillering, severe rot, and low yield, should be carried out once every 2 to 3 years, selecting paddy field, low-lying land and ditches suitable for fertility, leeward, and muddy feet. Although the drought and flood can be cultivated in the drylands, it is better to use low-humidity land. I want to plant deeply. The land should be deep-turned and requires more than 30cm.
At present, the method of early transplanting or pregerminating and then planting are often used in production to achieve early maturation and high yield. The pods can be planted in close proportion and the amount of fertilizer needed after planting is large. More than 2000kg of organic fertilizer is used in mu, and plant ash and superphosphate are applied. 15 days before the planting of leeches, 2000-2500kg of Mushi green ragweed was used as the base fertilizer. The seedling stage combines shallow cultivator and light fertilizer. After every 15-20 days combined with cultivating soil, the concentration of chase fertilizer gradually increased, and it is usually appropriate to apply 3-4 times. When spraying the leaves, add the appropriate amount of "Geguozhuangling" capsules to the liquid and stir evenly to spray. It can make taro leaf green and strong plants, promote the growth and weight gain of underground fruit, and produce high quality taro. During the entire period of childbirth, we must always keep wet, prevent accumulation of water (except waterlogging), depending on the weather, ground irrigation. The timely spraying of “new high fat film†moisturizes and protects the skin, prevents flooding and disease prevention, and reduces adverse effects on plants caused by prolonged drought, even in adverse weather conditions, and restores physiological vitality. Soil cultivation is one of the important measures for the high yield of Shantou, which can promote the occurrence of adventitious roots, improve the ability of drought resistance, inhibit the growth of terminal buds, and favor the development of hypertrophy of bulbs. Generally, the soil was cultivated 3 times. When the lateral buds were found out, they were pressed into the soil to avoid consumption of nutrients.
