Vegetable paddy-upland rotation cultivation device and cultivation method

Abstract

The invention discloses a vegetable paddy-upland rotation cultivation device and cultivation method. The device is characterized in that artificial paddy fields are disposed in a greenhouse, and continuous anti-seepage materials are paved at the bottom of each paddy field and beside ridges; soil layers 20-30cm in thickness are paved on the anti-seepage materials. During construction, 20-30cm of soil is dug from the surface of an appropriate area, the anti-seepage materials are paved after the dug part is tamped, at least 50cm is reserved on the periphery, the dug out soil is filled back, the reserved anti-seepage materials are fixed on the ridges to totally cover the same, and water is filled to form a pond with water at least 20cm in height. By the vegetable paddy-upland rotation cultivation device, paddy-upland rotation can be performed in any vegetable bases at any time, land vegetables can be planted in water-shortage or sand areas while aquatic vegetables such as lotus root, water bamboo, water pack, water chestnut can be planted, and aquatic vegetables can be planted in areas around lakes and rivers and with high underground water level by means of flooding while land vegetables such as melons and fruits can be planted by means of water controlling.

Description

technical field [0001] The invention relates to a cultivation facility and a cultivation method of vegetables in paddy and dry crop rotation. The utility model belongs to the technical field of agricultural (vegetable) cultivation. Background technique [0002] After more than 30 years of development, protected gardening in my country has basically formed facility types, production models and technical systems with different regional characteristics. The cultivation area of ​​protected vegetables has exceeded 2 million hectares. From the perspective of facility types, large and medium greenhouses account for about 40%, solar greenhouses account for about 20%, and multi-span greenhouses account for less than 0.5%. In the middle and lower reaches of the Yangtze River, mainly through the development of facilities such as plastic greenhouses, the area accounts for about 18% to 21% of the country's total. With the development of specialization and large-scale production of faci...

Problems solved by technology

In recent years, research has been carried out on new varieties and new technologies of protected cultivation of aquatic vegetables, and new models of water and dry rotation of protected vegetables to control continuous cropping obstacles. When early-maturing cultivation was carried out in early spring, the cold water frequently poured into the external river affected the increase and maintenance of the temperature in the facility. , thus affecting the effect of early-maturing cultivation
