The konjac, also known as the flower pole, the flower pole south star, the numbness, etc., scientific name, is a perennial herb of Araceae, is a perennial herb. It is determined that konjac contains a large amount of glucomannan and 17 kinds of amino acids required by the human body, as well as a variety of unsaturated fatty acids. The main planting species are flowers konjac, red konjac and white konjac. The flowers are available for viewing. The underground tubers are flat and round with rich nutrition and wide range of uses. After being detoxified, it can be processed into delicious and delicious foods, and has a medical function of dampness, phlegm, spleen, spleen, swelling, attacking poison and lowering cholesterol. In industry, konjac products can replace pectin, guar gum, cigarette paper, tape, film, textile printing and dyeing sizing, and architectural coatings, pesticides, cosmetics additives. Because the economic benefits of planting konjac are high, it has become an important economic crop in some rural areas. However, konjak cultivation in the past was more common in small areas planted in front of houses, the level of cultivation technology was low, many cultivation and management problems occurred, and serious pest and disease emerged. The applicable cultivation techniques are described below. First, the land konjac hi cold climate, resistant to dampness. The soil is suitable for deep, light sandy soil. Heavy clay and cold sandy soil should not be used to grow konjac. Avoid heavy land and the former is the land of pepper and tobacco. The soil pH 6.5~7.5 is suitable. Among them, the slopes with a slope of 5 to 10 degrees on the southern slope of the low mountain are best. Combined with site preparation, 2500 kg of organic fertilizer is applied per acre to deep-level and level. Second, nursery flower konjac's breeding coefficient is higher, so their breeding methods are also more. The commonly used bulblet cultivation method: Select the bulbs with similar vertical and horizontal diameters, the buds are small and shallow, the bulbs are full, the top buds are stout, the upper part of the tuber has a trace of broken or shedding roots, the bottom and the bottom are smooth, no roots, no Crimping, no scars, no injuries, bulbs weighing less than 500 g are seed pods, good weather before sowing, drying for 1 to 2 days, and then 72% for 10 million units of agricultural streptomycin 800 times, 40 % Formalin 500 times, 50% carbendazim WP 800 times soaking for 30 minutes, soak after drying. The method of sowing seedlings is used. One species per hole is planted, and the plant spacing is 23 to 33 cm. After sowing, the plant species are covered with fine soil. Third, planting in the original whole good land digging 15 to 20 cm deep sow ditch, according to 1540 cm spacing planting seedlings, replanting the next species before the base fertilizer, dosing with potash, organic fertilizer applied per acre 1500 kg, potash fertilizer 5 kg. Fertilizers and seed pods cannot be contacted. After the seed is applied, cover 3.5 to 5 cm of fine soil and apply fertilizer to the seedlings. The pods should be tilted and scattered to prevent drought and rain, so as to facilitate the rapid emergence of buds without damaging the normal growth of buds and sprouts. Fourth, the management of konjac is a strong fertility crops, must be applied before the next base fertilizer, basal organic fertilizer to delay the main growth period to top dressing 3 to 4 times, after the emergence of timely dressing. One cultivator per time, that is, topdressing once, cultivating one time. Diluted manure after 1 hour of white dew, followed by potassium and nitrogen fertilizers, followed by phosphate fertilizer. If some leaf petioles are found and the leaves are thin and thin, the color of the leaves should be immediately replaced with urea or human waste. In particular, fertilizers should be applied during the expansion and extension of bulbs, and compound fertilizers with 15 to 20 kg of fertilizer should be used in Mu. In the topdressing period, we should combine shallow plough weeding and we should not carry out cultivating in the later period. Flower konjac is afraid of drought. If the soil is dry, it should be sprayed or irrigated in time. The excess water should be drained. V. Prevention and control of pests and diseases Due to the high resistance of konjac in production and cultivation, there are fewer pests and diseases. Only a small amount of soft rot, blight, and bacterial leaf blight. Soft rot can be flooded with 70% carbendazim 1000-fold dilution; white tinea can be sprayed with 70% thiophanate-methyl 800-1000 dilution, spraying once every 7-10 days; bacterial leaf blight should be found after The diseased leaves were removed in time and eliminated with a 1:1:120 Bordeaux mixture. The onset of the disease is from July to August. The diseased plants were found to be removed in time, and lime powder or sulfur powder was sprinkled around the diseased plants to prevent the disease from spreading. At the same time, with 50% carbendazim WP 1000 times spray, once every 10 days, 2 or 3 times in a row to achieve control effect. 6. Harvest According to the growth habit of konjac, the whole growth period is about 7 months. When the stems on the local area turn yellow, they can be harvested. The best harvest period is about 1 month after inoculation in October, because underground tubers can continue to grow within 1 month after inoculation. If there is not much rain after seedling, frost and snow are not enough, and the weather is warm, then the excavation time may be delayed appropriately to increase the output. After the excavation, the konjac will be spread separately between the good hoe and the scar. After the water vapor is blown, it will be piled, stored, or sold on the floor of the room or on the surface of moisture-proof materials such as linoleum.
