Sagittaria sagittifolia storage method

Abstract

The invention relates to a Sagittaria sagittifolia storage method. The method comprises the following steps: directly putting Sagittaria sagittifolia dug and harvested in the natural dormancy period of Sagittaria sagittifolia into a plastic bag with mud without cleaning, tying up the bag opening of the plastic bag, then burying the plastic bag filled with Sagittaria sagittifolia into paddy field soil for less than 20 cm, and fully wetting surface soil of the paddy field soil until a water layer appears. The strength of the plastic bag meets the standard that the plastic bag is not damaged after being buried in soil. The natural dormancy period of the Sagittaria sagittifolia is from maturation of the Sagittaria sagittifolia in autumn to temperature rise and terminal bud germination of the Sagittaria sagittifolia in early spring of the next year. Corner plots close to a water source are selected as paddy field soil for burying the plastic bags filled with Sagittaria sagittifolia. The method can prolong the storage time, and prolongs the marketing supply period to be connected with the greenhouse arrowhead marketing period at the end of June early spring, so annual Sagittaria sagittifolia supply is achieved.

Description

technical field [0001] The invention relates to a storage method for sagittarius, belonging to the technical field of agricultural (vegetable) cultivation. Background technique [0002] Under natural conditions, Sagittarius is generally harvested and marketed in the three seasons of autumn, winter and spring. In spring, when the temperature is stable above 15°C, the terminal buds germinate, and the quality declines and the sale is terminated. Greenhouse cultivation in early spring can be harvested and marketed at the end of June. In recent years, due to the expansion of the planting area, the market has fluctuated greatly. In the three seasons of conventional planting in autumn, winter and spring, there have been cases where the sales price was too low, which led to many cases of farmers who planted arrowroot. [0003] Various places are also constantly exploring the storage technology of sagittarius. Common storage methods for conventional open-field cultivation of sagitta...

AI Technical Summary

Problems solved by technology

It can be seen that the conventionally cultivated Sagittarius is mainly sold in autumn, winter and spring from September to April of the following year, and it is difficult to delay the market until early summer by conventional storage methods; at the end of June, there are no Sagittarius cultivated in greenhouses in early spring for about 2 months before the market. Gap period for sale

[0004] Storage technologies such as controlled atmosphere preservation require special cold storage, and the construction cost is relatively high. The simple preservation technology currently disclosed cannot be delayed until the end of June to connect with the harvesting and marketing period of Arthia sativa cultivated in greenhouses in early spring, so as to achieve annual market supply.
