Embodiment

[0087] The embodiment of the present invention provides a high-yield cultivation method for interplanting broad beans with corn in dry farming areas. Planting is suitable for arid and semi-arid areas with a thickness of 250-500 mm. Corn is planted with full-film double ridges, corn is planted in furrows, broad beans are planted in the soil-covered zone of the ridges, and one row of broad beans is planted for every two rows of corn. Broad bean planting is about 10 days earlier than corn planting, and corn planting is around mid-April. Such as figure 2 As shown, the full-film double-furrow planting method (A) is adopted, and corn and broad beans are interplanted (B).

[0088] Variety selection: Select high-yield and high-quality varieties with strong drought resistance and disease resistance, such as Jindan 60, Dunyu 10, Lianda 169, Shendan 16, Jinsui 4 and other varieties. Broad beans are selected from high-yield varieties, such as Lincan No. 10, Linxi Broad Bean, and Qingc...

Abstract

The invention belongs to the technical field of crop interplanting cultivation and discloses a high-yield cultivation method for interplanting corn with broad bean in a dry farming area. The method includes: selecting improved varieties; preparing soil and fertilizing; ridging and mulching, to be more specific, drawing rows before ridging, setting small ridges and large ridges, sequentially ridging, and using a white mulching film for mulching; timely sowing, to be more specific, performing broad bean spring sowing from the middle ten 10 days of March to early April, sowing the corn from the middle ten days of April to early May, and regulating planting density according to rainfall, wherein the corn adopts full-film double-ridge planting and is planted in furrows, the broad bean is placedon ridge face soil covering areas, and one row of broad bean is planted after every two rows of corn are planted; timely releasing the seedlings of the corn and the broad bean, topping, and performing top dressing; controlling diseases and pests in the seedling stage and the growth stage. The method has the advantages that the broad bean is harvested from late June to about the middle ten days and the last ten days of July, and the corn is harvested in the last ten days of October when corn leaves and ears become yellow and dry.

Description

technical field [0001] The invention belongs to the technical field of crop interplanting cultivation, and in particular relates to a high-yield cultivation method for interplanting maize and broad bean in dry farming areas. Background technique [0002] Currently, the closest prior art: [0003] Corn is one of the main crops in Gansu Province. With the further application and promotion of dry agricultural water-saving technologies such as full-film double-furrow sowing and "one film for two years", the planting range and area of ​​corn have gradually expanded. However, the economic return of a single corn planting method is low, and long-term planting is not conducive to the improvement of soil structure and the control of diseases and insect pests. This has opened up a new way to increase income for farmers with more people and less land. The technicians of the Lanzhou Agricultural Research Center conducted a large number of experiments in Gongjing Village, Gongjing Towns...
