Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] The research method of research paddy and dry crop rotation of the present invention influences soil property comprises the steps:

[0018] (1) According to the Chinese patent "A device for studying the influence of vegetable paddy and dry crop rotation on soil properties" (Jiang Jiezeng et al., patent number 201320328323.4), the device is used as a cultivation bucket, and the cultivation bucket is buried in the same plastic greenhouse.

[0019] (2) Dig the soil in the greenhouse and put it into a plastic bucket, flood the soil to make the soil compact, and finally make the soil depth to 40cm, the soil surface in the plastic bucket is equal to the soil surface in the greenhouse, and excessive fertilization will cause the soil to become salinized .

[0020] (3) After the control soil sample was taken on June 19, 12 water spinach plants with the same growth were ...

Abstract

The invention provides a research method for the influences of paddy-upland rotation on soil properties. Materials are the same variety of ipomoea aquatica, conventional dry farming, moist cultivation and flood cultivation are carried out at the same time, and then the influences of the three different planting modes on soil properties are compared. The device in the Chinese patent Device for Researching Influences of Paddy-upland Rotation on Soil Properties (the patent number is 201320328323.4) is used as a cultivation barrel; in the same rain shelter facility, the ipomoea aquatica is planted in the surface soil fully-moist cultivation mode, the flood cultivation mode and the conventional dry farming mode respectively. According to the research method for the influences of paddy-upland rotation on soil properties, the research on the influences of paddy-upland rotation modes, such as the conventional dry farming mode, the moist cultivation and the flood cultivation mode, on soil properties can be carried out in the same facility with other relatively consistent environmental conditions at the same time, and repeated tests with random block design can be carried out.

Description

technical field [0001] The invention belongs to the field of agricultural research, in particular to a research method for studying the influence of paddy and dry crop rotation on soil properties. Background technique [0002] Water-drain rotation can effectively control soil salinization (Lin Hongmei, Su Weiguo, Liu Bin, et al. Research and promotion of a new high-efficiency cultivation model of water-drain rotation in facilities—a watermelon-water spinach cultivation model in greenhouses in early spring[J]. Shanghai Vegetables . 2011(05): 50-51.; Hui Feihu, Zhang Yongtai, Liu Xueji, et al. Preliminary study on high-efficiency cultivation techniques of protected vegetables in paddy and dry rotation [J]. Changjiang Vegetables. 2011(16): 119-121.). But in the greenhouse of water shortage or sandy soil, it is difficult to maintain the water layer by flooding in the above-mentioned article. Zhang Na et al. compared the effects of watercress and watercress on soil salinity in f...
