魔芋人工栽培,单产高,受益快,产品畅销国内外,对振兴山区农村经济已显示重要作用,但要发展魔芋生产,必须做好魔芋的贮藏保种工作。我县芋农在长期的生产实践中成功地总结了就地越冬保种、地窖贮藏、土坑保种、室内保温贮种等保种方法。 1.就地越冬保种。是指当年不收挖魔芋球茎或根状茎而留在地里自然越冬。这种贮藏保种方法最安全、最经济,可以减少挖种时的损伤和贮藏中的腐烂损失。具体做法抓好如下四点:①在植株枯萎之前,每亩用15担腐熟人粪尿或5公斤尿素兑水淋蔸一次,以使植株枯萎之后仍能促使地下球茎继续膨大。②植株自然倒苗以后,立即用稻草、茅草、树叶等覆盖全 Artificial cultivation of konjac, high yield, rapid benefit, the best-selling products at home and abroad, to revitalize the rural economy in mountain areas has shown an important role, but to develop konjac production, konjac must be good storage and conservation work. Our county taro farmers in the long-term production practices successfully summed up the overwintering conservation, cellar storage, pit maintenance, indoor insulation and other seed storage methods. 1. Overwintering conservation in place. Refers to do not collect konjac bulbs or rhizomes that stay in the natural winter. The safest and most economical method of stocking and preserving can reduce the damage during planting and the decay loss during storage. Specific practices do a good job the following four points: ① before the plants withered, with 15 acres per acre matured human excrement or 5 kg of urea watered down once so that the plants can still make the underground bulb after withering continue to expand. ② natural inverted plant after the fall, immediately covered with straw, thatch, leaves and so on
