Problems solved by technology

At present, single-layer film (greenhouse outer film) is usually used to cover cultivation or open-field cultivation. In winter or early spring, the effective accumulated temperature is not enough, and it is difficult for asparagus to break dormancy and produce tender stems.

Embodiment 1

[0033] A method for promoting early covering cultivation of asparagus in greenhouses in winter and spring, the steps are:

[0034] (1) Plot selection and base planning:

[0035] Choose loamy or sandy loam fields with convenient irrigation and drainage and deep soil to build greenhouses. The greenhouses run north-south, with a width of 6 or 8m, a top height of 2.5 or 3.0 or 3.2m, and a shoulder height of 1.7 or 1.8m. The length depends on the field. Steel frame greenhouse.

[0036] Use an excavator to excavate drainage ditches around the base where asparagus is to be planted, so as to ensure the timely drainage of rainwater during the rainy season in spring and summer in the south. Plan the location of the greenhouse according to the 8m wide standard, and the distance between the greenhouses is 1m. At the same time, according to the actual situation of the base, plan the mechanical farming roads for transporting organic fertilizers and the pipe network system for installing i...

Abstract

The invention discloses a method for promoting early cultivation of multi-layer film covering of winter and spring in asparagus in greenhouse. The method comprises the following steps: (1) plot selection and base planning, (2) variety selection, (3) seedling raising, (4) field planting, (5) field management, (6) harvesting, and (7) multi-layer plastic film covering for early cultivation. The cultivation method breaks the long-term natural dormancy state of the asparagus in the winter and spring low temperature conditions, which leads to no asparagus harvesting of the cultivation of asparagus in southern China's greenhouses from the end of November to the end of February. The method for promoting early cultivation of multi-layer film covering greatly improves the planting efficiency of theasparagus. Compared with the existing open field and greenhouse cultivation, the harvesting period of asparagus is obviously early and the production and economic benefits of asparagus have been significantly improved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation methods, and more specifically relates to a method for promoting early cultivation of asparagus in winter and spring in greenhouses covered with multi-layer films. Background technique [0002] Asparagus (Asparagus), whose scientific name is Asparagus, belongs to the perennial herbaceous plant that can form tender stems in the Liliaceae Asparagus genus. It is native to the Mediterranean coast, and the suitable growth temperature is 15-25 ° C. It is dioecious. The edible organ is its tender stem, which has a delicious flavor, soft and delicious fiber, rich in nutrients, can increase appetite, and has multiple health functions such as lowering blood pressure, anti-tumor, and improving human immunity. At present, single-layer film (greenhouse outer film) is usually used in production to cover cultivation or open field cultivation. In winter or early spring, the effective accumulated tempera...
