High-efficiency stereoscopic cultivation method for vegetable in protected land

Abstract

The invention provides a high-efficiency stereoscopic cultivation method for vegetables in a protected land. The protected land at winter idle time in November after Asparagus is cleared is used for interplanting autumn-delayed broccoli. Dwarf sword beans are interplanted among Asparagus rows after the broccoli is harvested in February of the next year. Therefore, three kinds of crops, i.e. the Asparagus, the broccoli and the dwarf sword beans can be produced in the same land plot. Since a stereoscopic cultivation mode of high-stem crops and dwarf crops is adopted, the land, temperature and light resources are fully utilized, the annual multi-cropping index reaches 300 percent and the planting benefits are improved; and under the nitrogen fixation effect of root nodule bacteria at the roots of the dwarf sword beans, the goal of nourishing soil by planting in the soil is realized, and the economic and the ecological benefits are remarkable.

Description

[0001] technical field [0002] The invention belongs to the technical field of vegetable cultivation, in particular to a method for efficient three-dimensional cultivation of vegetables in protected areas. Background technique [0003] Asparagus (Asparagus), scientific name of Asparagus, belongs to Liliaceae, Asparagus, is a dioecious perennial herbaceous plant, native to the Mediterranean coast. The edible organ is its tender stem, which has delicious flavor, soft and delicious fiber, rich in nutrients, can increase appetite, and has certain curative effect on protein metabolism disorders, liver dysfunction, arteriosclerosis, hypertension and other diseases. curative effect. Since the 1980s, with the continuous improvement of people's living standards, the consumption of asparagus has also continued to rise, and the planting area of ​​asparagus has continued to expand, with good economic benefits. [0004] With the continuous development of asparagus production, my count...

AI Technical Summary

Problems solved by technology

[0005] Asparagus generally has a small amount of harvest in the first year and the next year of planting, and the output increases in the third and fourth years. The total harvest period can reach more than 10 years. More than one year, high cultivation technology requirements and other reasons cause farmers to plant asparagus with high risks, which affects farmers' enthusiasm for planting asparagus in protected areas

At the same time, only one variety of asparagus is planted in each plot of traditional asparagus protected land cultivation, resulting in low land utilization rate and low economic benefits, which hinders agricultural efficiency and farmers' income increase
