Problems solved by technology

However, the salinity (NaCl content) of the water used for irrigation reaches or exceeds 1.3%, and a large amount of salt is accumulated in the cells of the edible part, which makes the edible taste too salty, and it needs to be soaked in fresh water when harvesting and eating.

Embodiment 1

[0029] Embodiment 1, the cultivation of sea asparagus

[0030] The cultivation experiment of sea asparagus was carried out in East China, and the seeds were sown in the middle and late February.

[0031] 1. Seedbed management:

[0032] (1) Turn over the seedbed:

[0033] ① Inlet ditch, drainage ditch, ring ditch, and three ditches are matched to improve the irrigation system.

[0034] ②At the end of December, carry out deep plowing of saline-alkali land, with a depth of 35-40 cm, and do ridge-drying for more than two months.

[0035] ③Prepare the flat field and make a furrow for standby use. The width of the furrow surface is required to be 50-60 cm, the moisture content to be 20-30 cm wide, and the depth to be 20-30 cm.

[0036] ④ At the end of each year, soil composition sampling and analysis will be carried out around and in the middle of the field to compare the changes in soil composition after sea asparagus planting, and make detailed records.

Abstract

The present invention discloses a method for cultivating euhalophyte sea vegetables, including alternately irrigating the euhalophyte sea vegetables with sea water and fresh water during the process of euhalophyte sea vegetables growth, in particular, irrigating with sea water until 7 to 20 days before harvest, and then irrigating with fresh water until harvest. The cultivation method of the present invention can reduce the salinity in halophyte, and thereby the euhalophyte sea vegetables does not need to add salts or be soaked with fresh water for eating so as to have suitable mouth feel, the palatability and the edible quality are improved obviously, and the cultivation method can also increase yield.

Description

technical field [0001] The invention relates to a method for cultivating true halophytic seawater vegetables. Background technique [0002] According to the difference of salt tolerance, plants can be divided into halophytes and non-halophytes. Its generally accepted definition (H Greenway and R Munns, 1980.Mechanisms of Salt Tolerance in Nonhalophytes.Annual Review of Plant Physiology, Vol.31: Page 149-190) is: able to contain at least 3.3bar (equivalent to 70mmol / The flora growing in the habitat of L monovalent salt) osmotic pressure salt water belongs to halophytes, and the plants that cannot grow or complete their life history in the above habitats are non-halophytes, also known as sweet soil plants. Halophytes have a series of salt-resistant characteristics physiologically, Breckle (SW Breckle, 1990.Salinity tolerance of different halophyte types.In: Brassam NE1, DambrodtM, Loughman BC (eds). Genetic Aspects of Plant Mineral Nutrient.Netherland: Kluwer Academic Publi...
