Konjac is a high-yield and high-efficiency economic crop that has been developed and cultivated in recent years. The output value per mu can reach 3,000 to 6,000 yuan, which has become a new bright spot for farmers to increase their income. To make konjac really achieve high yield and high efficiency, the following points must be kept during cultivation:
First, choose the site preparation. Konjac is different from general crops and requires strict soil requirements. It is generally appropriate to choose a neutral or near-neutral, deep soil layer, loose air, and more shade and cool land. We must intensively plow the selected plots and plow about 35 centimeters. If it is a flat land, it should be completed into cars, so that the car is leveled and the “two ditch†is opened. The waist groove is 80 cm wide, 50 cm deep, and the ditch is 40 cm wide and 50 cm deep, so that the ditch can communicate with each other. Rain lived in the field. If it is continuous cropping, the bacteria source base is large, and the incidence is heavy. It is necessary to combine the soil preparation and application of ash, lime mixed powder 85 to 100 kg, and sulfur 1 kg for soil sterilization.
Second, the selection of species. The species is selected in two batches. For the breeding of quail clams, small clams and whip crumbs below 250 g should be selected; for the commercial cultivation of clams for field cultivation in the same year, 250 to 1000 g of medium clams should be selected. The requirements are: yellowish skin, smooth surface, and upper bulb Flat, small nest, the whole bulb is axillary or taro shape, neat shape, scale buds thick and short, no disease, no pests and no mechanical damage.
Third, the kind of disinfection. 3 to 4 days before sowing, choose a sunny day to sow the sun or smoke with a firewood. When the sun is shining, do not overlap the seed pods and keep turning 2 or 3 times a day to reduce the water content by about 20%. Seed soaking in the pesticide is soaked with 50% wettable carbendazim powder 1000 times for about 7 hours, then removed and dried, and mixed with sulfur powder, lime, and ash to mix with the seed quail, which can kill the surface of the seed pod. Bacteria.
Fourth, timely sowing. Konjac is the youngest species emerging in spring sowing crops. It is generally only in early May to late. Seeding early, the applied base fertilizer loses fertilizer effect prematurely, and the konjac absorbs less; the sowing is too late, the top bud grows tall, and it is not easy to apply manure and cover soil, and it is easy to damage the top bud. Therefore, it is advisable to sow the temperature to rise above 15°C, and it is generally better to sow in the middle of April.
Fifth, apply the base fertilizer. Konjac is a crop that requires a large amount of fertilizer. The amount of base fertilizer should account for about half of the total amount of fertilizer, mainly pig manure and soil miscellaneous fertilizer, add a small amount of compound fertilizer, generally Mushi 7000 ~ 8000 kg ring month Pakistan, 25 kg compound fertilizer.
Sixth, reasonable dense planting. The density of planting should be determined according to the size of the species. If it is too thin, the land cannot be fully utilized. The yield is not high, but the density is poor when it is too dense. The breeding ground of common species is 3500-4000 litters per acre, and commodity litter is about 3,000 litres per acre. At the same time, some high-stalked crops such as corn and sorghum should be selected to provide shade and summer heat, avoiding high temperature in the summer and strong sunlight causing dead seedlings to meet the ecological conditions of the konjac high yield.
