White asparagus ridging-free cultivation method

Abstract

The invention relates to a white asparagus ridging-free cultivation method and belongs to field of asparagus cultivation. White asparagus is produced by using a high-density sunshade net to make a frame so as to cover the white asparagus, ridging-free cultivation is achieved, a planar support is 40cm away from a bed surface, the sunshade net covers the periphery of the support, a layer of straws is laid on the sunshade net to enhance sunshade effect during the asparagus harvesting season, the sunshade net is 6-stitch high-density black sunshade net with sunshade rate as high as 95%, sunshade processing can be performed effectively, matched farm operations such as water and fertilizer management and asparagus harvesting are provided, the produced white asparagus is pure white in color, and the average yield per mu can reach more than 1200kg in the second year of planting. Compared with traditional earthing blanching cultivation methods, the cultivation method has the advantages that steps such as ridging and ridge removing are omitted, asparagus can be harvested without push aside soil layers, labor is saved, white asparagus production efficiency is increased, large planting density and high yield are achieved, and the cultivation method is suitable for being popularized and applied, especially suitable for white asparagus production in the southern areas, and is promising in application prospect.

Description

[0001] technical field

[0002] The invention belongs to the field of asparagus cultivation (A01G 1 / 02), and in particular relates to a soil-free cultivation method for white asparagus. Background technique

[0003] White asparagus is cultivated by covering and softening the tender stems of asparagus during the sprouting period. The tender stems are white in color due to the growth without sunlight. Although its nutritional value is far inferior to that of green asparagus, due to the long-term tradition of eating canned white asparagus by European consumers in the place of origin, my country has mainly produced white asparagus for a long time, and the white asparagus produced is mainly used for processing asparagus Canned food is exported to Europe and earns a lot of foreign exchange for the country. According to statistics from the 12th International Asparagus Conference, the total area of ​​asparagus planted in the world reached 195,879 hectares in 2009, of which the plant...

Embodiment Construction

[0015] The present invention will be further elaborated below in conjunction with accompanying drawing and embodiment;

[0016] 1) Planting plot selection

[0017] Choose flat terrain, convenient drainage and irrigation, deep soil, loose soil, rich in organic matter, good water and fertilizer retention loam or sandy loam field, build a greenhouse, the greenhouse faces north and south, the width of the shed is 6-8 meters, and the height of the shed is 2.6 meters. ~2.8 meters, shoulder height 1.5~1.8 meters, or multi-span greenhouses with better conditions, the length depends on the field, and the scaffolding materials can be bamboo frames, steel pipes and other materials;

[0018] 2) Variety selection

[0019] Choose excellent first-generation hybrid varieties with strong stem pressure resistance, long tender stems, tightly packed bamboo shoot heads, and not easy to fall apart under high temperature, suitable for white asparagus production, such as UC115, Atlas, H668, Italo, J...
