Problems solved by technology

However, the intensive breeding method not only occupies land resources, but the cost of breeding is inevitably high, and under high-density conditions, on the one hand, it is easy to cause the spread of diseases, it is difficult to prevent and control, and the mortality rate is high; on the other hand, it cannot guarantee the quality of the water environment and leech product quality

Embodiment 1

[0023] The method for raising leeches in paddy fields of the present invention comprises the following steps:

[0024] A. Paddy field selection: The paddy field is selected in a place with sufficient water source, convenient drainage and irrigation, good water quality, good water retention, and an area of ​​667 square meters; dig ditches around the field, and excavate roads in the field to connect with the ditch to form "wells" and "wells". "Feng" shaped inlet and outlet are provided with nylon mesh to prevent leeches from escaping. Anti-escape nets are set at the inlet and outlet, and anti-escape nets are also set around the paddy fields;

[0025] B. Rice transplanting: choose rice varieties with long growth period, hard stalks, resistance to diseases and insect pests, and strong tillering;

[0026] C, leeches are kind put in: 300 kilograms of decomposed organic fertilizers are applied per 667 square meters in 10 days before putting in, and aquatic plants such as Hydrilla ve...

Embodiment 2

[0035] The method for raising leeches in paddy fields of the present invention comprises the following steps:

[0036] A. Paddy field selection: The paddy field is selected in a place with sufficient water source, convenient irrigation and drainage, good water quality, good water retention, and an area of ​​800 square meters; dig ditches around the field, and excavate roads in the field to connect with the ditch to form "wells" and "wells". "Feng" shaped inlet and outlet are provided with nylon mesh to prevent leeches from escaping. Anti-escape nets are set at the inlet and outlet, and anti-escape nets are also set around the paddy fields;

[0037] B. Rice transplanting: choose rice varieties with long growth period, hard stalks, resistance to diseases and insect pests, and strong tillering;

[0038] C, leech species throwing in: 300 kilograms of decomposed organic fertilizers were applied per 667 square meters in 10 days before putting in, and aquatic plants such as Hydrilla...

Embodiment 3

[0047] The method for raising leeches in paddy fields of the present invention comprises the following steps:

[0048] A. Paddy field selection: The paddy field is selected in a place with sufficient water source, convenient irrigation and drainage, good water quality, good water retention, and an area of ​​1,000 square meters; dig ditches around the field, and excavate roads in the field to connect with the ditch to form "wells" and "wells". "Feng" shaped inlet and outlet are provided with nylon mesh to prevent leeches from escaping. Anti-escape nets are set at the inlet and outlet, and anti-escape nets are also set around the paddy fields;

[0049] B. Rice transplanting: choose rice varieties with long growth period, hard stalks, resistance to diseases and insect pests, and strong tillering;

[0050] C, leeches are kind put in: 300 kilograms of decomposed organic fertilizers are applied to every 667 square meters in 10 days before putting in, and aquatic plants such as Hydr...

Abstract

The invention discloses a paddy field leech mixed-culture method which includes the steps of paddy field selection, rice inserting planting, leech fry throwing, raising management, paddy field fertilization and the like. Based on an existing leech culture technology, a green environment-friendly leech culture technology combined with rice planting is provided, effective measures are taken according to local conditions without occupying extra land resources, the existing culture technology and methods are integrated, a culture management mode integrating rice planting and leech culture is built by the aid of the ecology principle, leech culture cost is obviously reduced, the economic benefit of unit land area is greatly improved, and the quality and the yield of leeches are ensured.

Description

technical field [0001] The invention relates to a leech breeding technique, in particular to a high-yield nested leech breeding technique in an organic paddy field. Background technique [0002] Leeches belong to the phylum Annelida and the class Hirrdinea in terms of animal classification, and are commonly known as leeches, horse turtles, and inner drills. At present, there are about 500 species in the world, and about 10 species have been found in my country. Generally, the leech involved in the prior art refers to the wide-bodied golden leech (Whitmania pigra Whitman). Under natural conditions, it usually lives in freshwater lakes, rivers, ponds, ditches and rice fields. The broad-bodied golden leech does not suck blood, but mainly feeds on the body fluids or soft tissues of invertebrates, such as snails, river mussels, earthworms, aquatic insect larvae and plankton, and sometimes also feeds on humus in the water surface or soil on the shore. Leech is a traditional spe...
