Plant planting structure for water surface planting

Abstract

The invention provides a plant planting structure for water surface planting, and belongs to the technical field of agriculture. The plant planting structure comprises a planting box and an outer sheath. The planting box is a conical box body with the lower end diameter smaller than the upper end diameter. The upper end of the planting box is opened. The planting box is detachably connected into the outer sheath and filled with soil for planting plants. The outer sheath is of a polygon prism structure with the even number (larger than four) of edges. L-type limiting grooves are formed in the two opposite inner wall surfaces in the outer sheath. Each limiting groove comprises a vertical section and a transverse section. The vertical sections in the two opposite limiting grooves are consistent in length. The vertical sections of the two limiting grooves in the adjacent edges in the outer sheath are consistent in length. Two limiting pins are symmetrically arranged on the outer surface ofthe planting box and can be slidingly connected into the limiting grooves. The plant planting structure has the advantages that the above-water distance of the planting box can be adjusted and the plant planting structure is suitable for growth of different plants in different growth periods.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a plant planting structure for water surface planting. Background technique [0002] With the growth of population and the advancement of industrialization and urbanization, the area of ​​arable land in my country is decreasing year by year; at the same time, the quality of problems such as soil pollution, salinization, and desertification is deteriorating day by day, resulting in a decrease in arable land area and a decline in productivity, ensuring food security. The contradiction between grain and vegetables competing for land will become increasingly prominent. [0003] my country's natural water area is vast, with an area of ​​235,015.76km2 for freshwater lakes and 25668.59km2 for pond culture, which is equivalent to 20% of the country's arable land area, but it has not been well developed and utilized. Floating cultivation on water is a cultivation method in which crops ar...
