Abstract

The invention relates to a cultivation method for inter-planting Dioscorea opposita Thunb and early ripening maize. The cultivation method for inter-planting the Dioscorea opposita Thunb and the early ripening maize comprises the following steps that are carried out in sequence: a, soil preparation to prepare for planting: selecting a sandy loam or sandy soil plot, preparing soil for bedding in the middle ten days of March every year, and carrying out sterilization treatment before the Dioscorea opposita Thunb is planted; b, planting: transplanting bred maize seedlings on oblique planes on the two sides of the bed, and planting stems, which are subjected to pretreatment, of the Dioscorea opposita Thunb in the middle of the surface of the bed in the first twenty days of April; c, management: watering thoroughly once before the Dioscorea opposita Thunb is planted, applying compound fertilizer twice during the growth period of the maize, and erecting a vertical frame in the middle of the surface of the bed; d, maize harvesting: harvesting the maize in the middle ten days of June, and covering the surface of the bed by using maize straws after the harvesting; e, top application: applying the compound fertilizer to the Dioscorea opposita Thunb twice again, and carrying out earth covering in time after the application. The mode of culturing the Dioscorea opposita Thunb and the early ripening maize in an inter-planting manner is adopted for the cultivation method for inter-planting the Dioscorea opposita Thunb and the early ripening maize; the effective utilization rate of the soil is improved; the formation of a soil granular structure can be facilitated by a straw waste; a soil structure is effectively improved; meanwhile, the scouring of rainwater to the surface of bare soil is alleviated.

Description

technical field [0001] The invention relates to a method for cultivating yam, in particular to a method for interplanting yam and early-maturing corn. Background technique [0002] Yam (Dioscorea opposita Thunb.) belongs to Dioscorea family (Dioseoreaceae.) Dioscorea (Dioscorea L.), is an annual or perennial twining vine herbaceous vine. Because yam has both high edible and medicinal value, the growing area of ​​yam in our country is expanding year by year under the increasing awareness of national health care, and the economic benefits of planting yam are also becoming more and more obvious. one of the highlights. [0003] But at the same time, several problems also appeared. First, in the south, due to the slow germination of potato tubers in the early stage of planting yams, it takes about 40-50 days from the time when the tubers of yams are planted in the ground to when the seedlings germinate. For a period of time, the photosynthetic utilization rate of land was not h...
