Problems solved by technology

[0003] As for the duration of hydroponics, if the duration is short, it may lead to a large increase in the infiltrated salt due to soil capillary action after dry farming, and lead to salinization of the topsoil and the cultivated layer.

Embodiment Construction

[0009] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0010] The technical scheme adopted in the present invention is:

[0011] (1) From October 2011 to May 2012 in the aquatic vegetable experimental field of Yangzhou University. The duration lasted for 7 months, and the two greenhouses were respectively planted with wet-planted cress under the condition of fully moist soil: the surface soil on the border surface was required not to turn white; watercress was planted under flooded conditions: the border surface was required to maintain a water layer of 3-5cm. The two kinds of aquatic vegetables were transplanted on October 20, 2011, and the fertilization conditions during the planting period were consistent. I...

Abstract

The invention discloses a method for delaying or treating salination of vegetable soil in facilities. The method has the advantages that an EC (ethyl cellulose) value and the total negative ion content of the soil within a 30cm-depth surface layer can be obviously reduced by means of continuously keeping a sufficient moisture state for four months or a longer time and planting aquatic vegetables such as wettish-cultivated water dropwort in the facilities such as greenhouses for planting xerophilic vegetables, main positive ions of absorption layers of root systems of the vegetables are obviously reduced, ions such as SO<4><2->, Cl<-> and HCO<3><-> among main negative ions are obviously reduced while NO<3><-> among the main negative ions is retained, and an effect of delaying or treating the salination of the vegetable soil in the facilities is good.

Description

technical field [0001] The invention relates to a method for delaying or controlling soil salinization of facility vegetables. The utility model belongs to the technical field of agricultural (vegetable) cultivation. Background technique [0002] The paddy and dry crop rotation is a traditional ecological cultivation mode, which has a good effect of controlling soil salinization, and can reduce the salinity concentration of the surface soil and the cultivated layer (Fan Haoding, Wu Aifang, Zhou Shilong. 2004, research on soil salinization control technology for greenhouse vegetables .Yangtze River Vegetables, (04):48-49; Yang Xiangtian, Zhou Cui, Li Jianhui, Li Weilong, Lin Jun. 2010. Strawberry Yield and Soil Biological Characteristics in Greenhouses under Different Crop Rotation Methods. Chinese Journal of Ecological Agriculture, (02):312- 315). However, the current public water farming methods all need to maintain a long-term submerged state. Xia Yueming et al. 40(1):1...
