Method for utilizing fishpond to plant cresses

Abstract

The invention relates to the field of ecological cultivation, in particular to a method for utilizing fishpond to plant cresses. The method comprises following steps of seedling growing, preparation of a floating bed, and placement of cresses into the pond. Soilless culture indoor and outdoor is utilized for cultivating cresses so that cresses can be better adapted to the pond and an adaptation period is shortened and survival rate is improved. Activated carbon and vermiculites are added to the floating bed in order to effectively absorb nutrients in water for cresses. In the meantime, roots of cresses twine each other so that the number of cress roots entering below the floating bed is decreased. Even if herbivorous fishes exist, fishes cannot die because of damage to cress roots.

Description

technical field [0001] The invention belongs to the field of ecological breeding, in particular to a method for planting cress by utilizing fish ponds. Background technique [0002] With the promotion of ecological farming, more and more fish and vegetable symbiosis began to appear. Water vegetable planting adopts the three-dimensional agricultural planting mode of "growing vegetables on water and raising fish underwater", which not only makes full use of the space, but also improves the utilization rate of resources. Through the ecological cycle of "purifying water with vegetables, raising fish with water, and raising vegetables with fish", a lot of costs have been saved. At the same time, the three-dimensional planting technology of growing vegetables on the water does not use pesticides and fertilizers at all, and the cost is relatively low. The output and quality are better than land vegetables, and a large number of fish and shrimp can be harvested in autumn. Vegetabl...

[0003] However, most of the existing aquatic vegetable planting adopts land breeding and then is added to the floating bed for cultivation. Such vegetables will have a long adaptation period when they enter the fish pond, and the survival rate is not high, because most of the aquatic vegetable roots are concentrated in the water. As a result, it is often impossible to feed herbivorous fish in fish ponds during the breeding process to prevent herbivorous torpedoes from eating the roots of vegetables, resulting in the death of vegetables
