High-altitude area konjak film mulching, soil moisture preservation, temperature increasing and rain sheltering technology

Abstract

The invention belongs to the field of konjak planting, and discloses a high-altitude area konjak film mulching, soil moisture preservation, temperature increasing and rain sheltering technology. The high-altitude area konjak film mulching, soil moisture preservation, temperature increasing and rain sheltering technology comprises the following steps of S1, seed selection and seed konjak treatment,specifically, selecting seed konjak which is full in appearance and free of wounds, diseases and malformation, drying the seed konjak in the sun for 3-5 days until the skin of the seed konjak shrinksand the water loss rate reaches about 30%, coating the seed konjak with disinfection powder, framing the seed konjak, and placing the seed konjak in a shade place for later use; and S2, film selection, specifically, selecting a mulching film meeting the national standard of 'Polyethylene Blow-Molded Agricultural Ground Cover Film' (GB13735-92). According to the seed konjak technology disclosed bythe invention, direct breaking of the film for emerging is achieved; through application of a film mulching comprehensive technology, soil moisture content keeping, soil moisture keeping and controlling over soil moisture permeation in rainy seasons are achieved, weed growth is better controlled, labor investment is reduced, yield is increased, and diseases are reduced; and the technology is an efficient planting technology which can be popularized and applied in a high-altitude area on a large scale.

Description

technical field [0001] The invention relates to the technical field of konjac planting, in particular to the film-covered planting technology of konjac in high-altitude areas. Background technique [0002] Konjac is a plant of the genus Konjac in the Araceae family, and it belongs to the yam crop in cultivation. Konjac likes warmth and humidity, and is suitable for growth in an environment of 20°C to 30°C. The history of konjac cultivation in my country has more than 2,000 years. [0003] Southwest China is the main production area of ​​konjac planting, mainly distributed in Yunnan, Guizhou, Sichuan and other provinces. Konjac has high economic value and a long industrial chain. It has the effects of losing weight, lowering blood pressure, lowering blood sugar, detoxification and laxative, and has medicinal value such as reducing swelling and detoxification, and treating carbuncle sores. The market potential is huge. [0004] The output value per mu of konjac planting can ...
