Cultivation method for improving yield of Sichuan konjac

Abstract

The invention provides a cultivation method for improving yield of Sichuan konjac and relates to the field of crop cultivation. Deep ditch high-compartment cultivation is adopted, and the method comprises the following steps: soaking konjac seeds by utilizing medical fertilizer liquid to obtain seed konjac; seeding the seed konjac into a konjac field in which weeds are removed and a base fertilizer is applied, and covering a first mulching film on the konjac field, so that the emergence time of the seed konjac is shortened; immediately replacing the first mulching film in the konjac field witha second mulching film after emergence of the seed konjac, so that the resistance of emerging seed konjac is improved; performing field management comprising staged weeding on the emerging seed konjac, and finally harvesting the konjac. Since a mixture of Taifujing and Moyuling serves as the medical fertilizer liquid in the invention, and an alternately laminating technology is used, soft rot iseffectively controlled, the plant resistance is physiologically improved, growth of the konjac is promoted, and the yield of the konjac is improved.

Description

technical field

[0001] The invention relates to the field of plant cultivation, in particular to a Sichuan konjac cultivation method. Background technique

[0002] Konjac is a perennial herbaceous plant belonging to the family Araceae Konjac. It is an important special economic crop. Its main product, glucomannan, is widely used in the fields of food, medicine and chemical industry. There is no doubt about the high economic benefits of konjac, but the strict requirements on the environment and cultivation techniques, as well as the impact of major diseases such as soft rot and white silk, have resulted in the development of konjac planting in a bottleneck state, and it is difficult to improve the yield and quality. Excellent plant morphology and physiological traits are the prerequisites for konjac to obtain high yield and high quality. At present, more and more scholars have begun to study the cultivation of excellent konjac plants and the prevention and control of major di...

[0043] 1.1 Selection of Taro

[0044] For 5g taro seeds, the weight per mu is 50kg; for 10g taro seeds, the weight for mu is 100kg; for 50-100g taro seeds, the weight for mu is 250kg; for 100-150g taro seeds, the weight for mu is 400kg.

[0045] 1.2 Treatment of Taro

[0046] Prepare 375 times peptide rot cleansing and konjac spirit respectively. After fully mixing, the medicinal fertilizer solution is prepared, and then the selected seed taro is soaked in the medicinal fertilizer solution for 3 hours at room temperature, and finally the soaked seed taro is placed in the Wash in aqueous solution to remove rotten and scarred seed yams, dry the surface moisture of qualified seed yams to obtain seed yams to be sown, and set aside.

[0047] 2. Soil selection and planting method

[0048] Soil requirements: choose sandy loam soil with loose and fertile soil, no pathogenic bacteria, no stagnant water, good drainage, pH value between 5.5 ...
