Abstract
The invention discloses a water spinach facility cultivating method which aims to treat facility soil salinization. The water spinach facility cultivating method comprises the steps that in a facility such as a conservatory or a greenhouse in which arid crops are conventionally planted and salinization problems occur due to excessive fertilizer application, ridges are built on the periphery of the facility, the inner sides of the ridges are lined with plastic films to prevent moisture side leakage, beds with the width of 1.2 m to 1.5 m are built inside the facility, the depths of furrows range from 20 cm to 30 cm, and high-density direct seeding or high-density seedling transplantation of water spinach (a variety which is a water spinach type, grows vertically and has narrow leaves) is performed on the bed faces. Irrigation is performed according to the growth height of the plants and according to the limit that the plants needing growing are not flooded, water can also be retained in the furrows to keep the bed faces to be sufficiently wetted, and irrigation is performed again if the surface soil of the bed faces becomes white. Surface water or well water with low hardness is used for the irrigation water. Cut harvesting is performed with 5-8 cm stubble in an earlier stage harvesting process, and possible stolons growing transversely are removed in time so that disturbance to the population can be avoided; when the population tends to closing in a later stage, the density of the population is controlled through the height of the stubble and the depth of water flooding.
Description
Technical field
The present invention relates to a kind of water spinach facility cultivation method.Belong to agricultural (vegetables) culture technique field.
