Abstract

The invention discloses a konjac cultivation method. The method comprises the following steps of 1, land selection and preparation, wherein sandy soil which is high in breathability, deep and fertilein soil layer, good in irrigation and drainage condition, and has the pH value of 6.5-7.5 is selected, and the soil is turned over and aired; 2, seed selection, wherein konjac seeds which are flat inupper end openings, in a taro shape, and free of diseases and has small cells are selected; 3, planting, wherein the bud openings of the konjac obtained in the second step are flat put upwards according to spacing of 25-40 cm, and the planted seeds are compacted downwards; 4, cultivation management, wherein fertilization is conducted according to the growth situation of the konjac; 5, harvesting and reserving seeds for planting, wherein digging is conducted 15 days after 70% of plant seedlings fall down, and when the konjac is dug, the konjac which is smooth in surface, free of mechanical damage, and is 0.15-0.25 kg in weight is picked up to serve as seed konjac, and small tubers and rhizomes can be used for breeding the seed konjac. By means of the konjac cultivation method, the fertilization and management are reasonable, organic fertilizer is reasonably matched with chemistry, macroelements and medium-trace elements are reasonably matched, the yield of the konjac can be high, the quality is good, and the problem of soil hardening can also be solved.

Description

technical field [0001] The invention belongs to the technical field of vegetable planting, and in particular relates to a konjac cultivation method. Background technique [0002] Konjac, a perennial herbaceous plant of Araceae. Konjac is a big family. There are about 130 species in the world, and there are more than 30 species in my country. Konjac is the only economic crop that can provide a large amount of glucomannan discovered so far. The application value of konjac in food and medicine will continue to be recognized developed. Konjac is popular because of its high edible value. Its main ingredient is glucomannan, which not only contains more than 10 amino acids and various trace elements needed by the human body, but also has low protein, low fat and high fiber. , strong water absorption, high expansion rate and other characteristics. In terms of medicinal effects, it has various effects such as lowering blood fat, lowering blood sugar, lowering blood pressure, detoxif...
