Abstract

The invention discloses a konjak planting method including weeding, which comprises the following steps of: selecting a plot with deep soil layer, loose soil, fertile soil and convenient drainage andirrigation, deeply ploughing for 30-40cm, harrowing for thinning, ditching and ridging, wherein a ditching width is 1.0-1.5m, and a ridge surface width is more than or equal to 0.7m and less than 1.2m; digging ditches for drill sowing or hole sowing on the ridge surface from Qingming festival to Grain Rain, wherein a sowing interval is 30cm*40cm; meanwhile, mainly using an organic fertilizer or afarm manure, and taking a nitrogen-phosphorus-potassium compound fertilizer as an auxiliary base fertilizer; applying 200-300kg of the organic fertilizer per acre, applying 2000-3000kg of the farm manure per acre, and applying 40-50kg of the compound fertilizer per acre; immediately covering the whole ridge surface with pine needles / straws / hay with a thickness of 5-10cm or a straw mat with the thickness of 1-1.5cm after the planting is finished; in the first ten days of July, the konjak is sprayed with a foliar fertilizer every 10 days after an emergence of regular seedlings, and the foliar fertilizer is sprayed for 3 to 4 times. The emergence rate of the konjak reaches more than 95 percent, and 90 percent of weeds can be controlled.

Description

technical field [0001] The invention belongs to the technical field of konjac planting, and in particular relates to a method for planting konjac by covering and weeding. Background technique [0002] Konjac is the general name of the genus Amorphophallus Blume in the family Araceae. In ancient times, it was called grinding taro or konjac. According to the statistics of the China Konjac Association, in 2017, more than 2 million mu of konjac were planted in China, mainly in Yunnan, Guizhou, Sichuan, Hubei, Shaanxi and other provinces. The cultivated varieties are mainly flower konjac, and a small amount of white konjac and yellow konjac are planted in Yunnan. In the konjac planting industry, the development of the konjac planting industry is slow due to the difficulty in controlling diseases, insect pests and weeds, especially the damage caused by weeds to konjac production is difficult to calculate. According to the survey, there are generally more than 30 families and more...
