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...

There is no doubt about the high economic benefits of konjac, but the harsh 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 diseases such as soft rot, mainly from agronomic measures and chemical control. , studies have shown that according to the growth habits of konjac itself, creating a suitable growth environment for it can improve the growth quality and reduce the occurrence of diseases, but the improvement of environmental factors alone is still far from achieving the desired effect of production, so it is necessary to fundamentally To solve the problem of konjac production in the world, we must rely on the intervention of chemical control

[0003] At present, agricultural streptomycin is the most commonly used in the prevention and treatment of soft rot, but its therapeutic effect is not satisfactory, and it must be used repeatedly in the process of prevention and control to be effective. Practice has shown that agricultural streptomycin as a If antibiotics are used more often, bacteria will easily develop drug resistance. As a streptoconazole chelating agent, Tiefujing is used as a carrier of fungicides and auxiliaries purchased from Taiwan to combine streptomycin, chlorothalonil and myclobutanil. Chelated, the three fungicides achieve the most ideal synergistic peak, which better solves the problem of drug resistance and maximizes the efficacy. However, if the plant growth is weak, only rely on fungicides to inhibit soft rot The occurrence of konjac can not increase the yield of konjac
