Embodiment 1

[0029] According to the planting requirements of taro, corn and rice and other crops, ditch and ridge are carried out. The furrows between the ridges are alternately narrow, shallow-broad, deep-narrow, and shallow. The width of the narrow band is 15cm-25cm, and the depth of the shallow groove is 20cm-25cm; the width of the wide band is greater than 25cm-40cm, and the depth of the deep groove is greater than 25cm-40cm. About one meter away from the edge of the farmland, the ditch in the field is 30-60cm wide and 40-60cm deep (such as figure 1 shown). Keep the grooves open. Build 1-2 soil slopes at intervals of 25m-100m for each ridge, the soil slope height is 0.1m-1.0m higher than the cultivated land level, and the area is 4.0m 2 -10.0m 2 Left and right, the soil slopes are required to be sorted into a turtle-back shape. It is necessary to maintain a certain water layer in the ditch between ridges. When the water in the ditch in the farmland is small, it can be controlled...

Abstract

The invention discloses a farmland ricefield eel cultivating method. Ditching and ridging are carried out on a farmland meeting the requirements of planting taro, corn or paddy, the width of ridging channels are determined by narrow bands and wide bands at intervals, the depth of the ridging channels are determined by shallow ridges and deep ridges at intervals, and the ridging channels are mutually communicated. 1-2 soil slops are built on each ridge every other 25-100 m. Crops are planted on the ridges, ricefield eel seeds are thrown in the channels for cultivating ricefield eels, and angleworms are placed on the ridges for feeding the ricefield eels. In the invention, an innovated mode and technology for planting crops and cultivating ricefield eels is constructed, the problem of low income of the traditional ricefield eel cultivating method and pure crop planting of the farmland is solved, the cultivated land resource of the farmland can be sufficiently utilized, and the ecological environment of the farmland is improved. By adopting the technology, farmers can obtain benefits for many years after investing once.

Description

technical field [0001] The invention belongs to the three-dimensional ecological agriculture development model and supporting technology, in particular to a field eel breeding method related to the combination of planting and breeding. Background technique [0002] Three-dimensional agriculture, also known as layered agriculture, is to use light, heat, water, fertilizer, gas and other resources, and at the same time make use of the time difference and space difference in the growth process of various crops, to produce food on the ground, underground, under water, in the air, as well as in the front and rear. Simultaneous or interactive production, through reasonable assembly and matching of thickness and thickness, various types of multi-functional, multi-level, multi-channel high-yield and high-quality production systems are formed to obtain maximum economic benefits. For example, in the planting industry, strawberries are planted in grape fields, vegetables and medicinal m...
