Problems solved by technology
The first is to connect ponds with fields, and replace the water bodies of ditch with pond water to provide suitable habitats for crayfish. However, most rice fields are not adjacent to ponds, and it is difficult to realize the connection between ponds and fields.
The second is to dig deep ditches, that is, in a limited ditch, increase the depth and change the space for area, but it is difficult to dig deep ditches in most rice fields, because the edge is easy to collapse when the depth increases, and a large amount of silt enters the ditch to silt up
[0005] To sum up, the current three-dimensional comprehensive planting and breeding is facing the problem of reduced output and reduced output value, which urgently needs to be solved by adjusting the overall plan

Embodiment 1
[0038] like figure 1 As shown, in October 2016, the primary election of Yiqiu was 2503m 2 There are 9 springs in the cold soaking field, which are respectively located on two adjacent ridges, one is 91 meters (5 springs), the other is 27.5 meters (4 springs), and 4 trenches are excavated. The total area of trenches is controlled at 10 Within %, the springs shall be well maintained, and the mud excavated from the ditch shall be heightened to reinforce the field ridge, and the height of the field ridge shall be 50cm. Water inlets and outlets are set up on the field ridges. They are located on the two ridges without springs. The water inlets and outlets are equipped with anti-escape devices. When the water is not changed, the water inlets and outlets are closed to prevent the groundwater from the springs from flowing out. .
[0039] The drainage pipe should be placed horizontally, and the position of the drainage pipe should be controlled to be lower than the field surface, a...
Embodiment 2
[0062] In October 2017, on the basis of the original example 1, a new cold soaked field Liuqiu with the same specification was added. The selection standard is that there are springs, which are convenient for drainage and irrigation. The same method was used to carry out mixed three-dimensional comprehensive planting of mulberry, mulberry, elodea, Hydrilla verticillium, bitter grass, weed, water hyacinth, water peanut, rice, crayfish, crab, snail, and mussel. The harvest results are shown in Table 1. shown. Apply lime 15g / m every half month 2 , Splashing with chemical water, in case of abnormal weather, advance or postpone appropriately; dredging before the first application of lime, that is, dredging first and then sprinkling lime water. Manually clean the dirt, and sprinkle the dirty water in the middle of the rice to avoid hurting the crayfish.

Abstract
The invention discloses a three-dimensional comprehensive planting and breeding method, which comprises the following steps: selecting cold-soaked fields or rotten mud fields, and excavating surrounding ditches on the inner side of the field ridges so that the groundwater emerging from the springs cannot flow out and become temperature-adjusting water. The height of the field ridges is 40 ‑50cm, water inlet and water outlet are opened on the ridge of the field; the field is disinfected and fertilized respectively; crayfish seedlings are put in the field in November, and fished from March to April of the following year; aquatic plants are planted in the field in May of the following year. The invention can prevent excessive ditching, the growth stage of crayfish avoids the high temperature in summer, and uses groundwater to raise the temperature in autumn, winter and spring, so the growth is stable and the output is guaranteed; crabs cool down through trees, herbs, floating plants and submerged plants, and then The role of upper and lower water can grow normally in six, seven, eight, nine and other four months, and the output is guaranteed. Shrimp and crab grow in autumn and winter, spring, summer and autumn respectively, avoiding the symbiosis stage, reducing competition, and helping to improve Survival rate, commodity rate.
Description
technical field [0001] The invention relates to the field of agricultural planting and breeding, in particular to a three-dimensional comprehensive planting and breeding method. Background technique [0002] The three-dimensional comprehensive planting and breeding can grow aquatic plants such as rice, lotus root, lotus root, and wild rice stem. Among them, the three-dimensional comprehensive planting and breeding of rice fields not only provides food, but also increases the income of rice farmers. It kills two birds with one stone and provides economic guarantee for sustainable rice production. The perfect combination of agronomy in modern farming. Especially in recent years, comprehensive paddy farming has developed rapidly. Taking crayfish in paddy fields as an example, the provinces with an area of more than 1 million mu are Hubei, Hunan, Anhui, Jiangsu, and Jiangxi. These five provinces are also the core production areas of crayfish in my country. However, in the pro...
