Water spinach facility cultivating method

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 [0001] The invention relates to a protected cultivation method of water spinach. The utility model belongs to the technical field of agricultural (vegetable) cultivation. Background technique [0002] Planting aquatic vegetables under conditions of flooding and sufficient soil moisture can alleviate or even control facility soil salinization (Jiang Jiezeng et al., a method for delaying or controlling facility vegetable soil salinization, application number 201310324236.6, issue number 2013073000919900) . [0003] Sun Qianqian and Shen Yixin [2010, Effects of nitrogen fertilization and mowing frequency on water spinach regeneration and forage yield and quality, Grassland and Turfgrass, 30 (1): 14-19] think: the relationship between the yield of regenerated grass and the number of leaves, branches number and plant height. The number of ramets after mowing was related to the stubble height, and the number of ramets increased significantly after multiple mowin...

AI Technical Summary

Problems solved by technology

With this technology, after mowing, wait until the next seedling height is about 10cm before watering, the topsoil may dry out for a long time, which will lead to the increase of infiltration salt and reduce the treatment effect.

[0007] In addition, in practice, it is found that due to sufficient water and brittle stems, the broad-leaved varieties are prone to lodging and creeping growth after growing tall, disturbing the population, and inconvenient for management and harvesting
