Embodiment 1

[0042] The present embodiment provides the preparation method of Chinese medicine feed of the present invention, specifically comprises the following steps:

[0043] Step 1. Weigh each raw material by weight, and said raw material comprises the following components: 3-5 parts of Andrographis paniculata, 3-8 parts of Artemisia annua, 5-9 parts of Houttuynia cordata, 10-20 parts of soybean meal powder;

[0044] Step 2: decoct Andrographis paniculata with 5 times the amount of water twice, each time for 1 hour, filter, combine the filtrates, concentrate to a relative density of 1.10 (40°C), and obtain Andrographis paniculata extract;

[0045] Step 3. After pulverizing the Artemisia annua and Houttuynia cordata through a 20-mesh sieve, the Artemisia annua powder and Houttuynia cordata powder were obtained;

[0046] Step 4. Mix the Andrographis paniculata extract, Artemisia annua powder, Houttuynia cordata powder and soybean meal powder evenly and then granulate. Mpa, the compress...

Embodiment 2

[0048] The present embodiment provides the crayfish breeding method of the present invention, specifically:

[0049] Step 1. Field selection: select fields with sufficient water sources, no pollution in water quality, fertile soil, and sufficient sunlight;

[0050] Step 2. Field preparation: before transplanting rice seedlings, dig a ring-shaped ditch in the paddy field, then sterilize and fertilize the water quality;

[0051] Wherein, an annular ditch is dug in the paddy field, the annular ditch is 50 cm away from the field ridge, and the size of the annular ditch is 3.5 meters wide and 1.6 meters deep; an anti-escape net is set between the annular ditch and the field ridge, and the anti-escape net is placed on the ground. Both the part and the underground part are 40cm.

[0052] The specific operation of sterilization is as follows: before planting the seedlings, the annular ditch is sterilized with quicklime or bleaching powder, and the consumption of the quicklime or blea...

Embodiment 3

[0060] The present embodiment provides the crayfish breeding method of the present invention, specifically:

[0061] Step 1. Field selection: select fields with sufficient water sources, no pollution in water quality, fertile soil, and sufficient sunlight;

[0062] Step 2. Field preparation: before transplanting rice seedlings, dig a ring-shaped ditch in the paddy field, then sterilize and fertilize the water quality;

[0063] Wherein, an annular ditch is dug in the paddy field, the annular ditch is 80 cm away from the field ridge, and the size of the annular ditch is 4.5 meters wide and 1.3 meters deep; an escape net is set between the annular ditch and the field ridge, and the escape net is ground Part and underground part are 30cm.

[0064] The specific operation of sterilization is as follows: before planting the seedlings, the annular ditch is sterilized with quicklime or bleaching powder, and the consumption of the quicklime or bleaching powder is 50 kg per mu.

Abstract

The invention discloses a method for cultivating crayfish in a rice field and solves the problems that crayfish is easily attacked by diseases and is long in growth cycle and low in yield in the priorart. The method includes: selecting a field; preparing the field; planting seedlings; adding young crayfish into the field; performing feeding management; catching the crayfish. By the method which is scientific and simple to operate, the cultivated crayfish cannot be easily attacked by diseases and is short in growth cycle and high in yield.

Description

technical field [0001] The invention belongs to the technical field of cultivation, and in particular relates to a method for cultivating crayfish in paddy fields. Background technique [0002] Crayfish (scientific name: Procambarus clarkii): also known as Procambarus clarkii, red crayfish and freshwater crayfish. Crayfish has a wide range of adaptability and a wide range of suitable growth temperatures. It can grow and develop normally when the water temperature is 10-30°C. It can also withstand high temperature and severe cold, can withstand high temperatures above 40°C, and can survive the winter safely when the temperature is below -14°C. Crawfish grows rapidly. Under the condition of suitable temperature and sufficient bait supply, after more than 2 months of breeding, it can reach sexual maturity and reach the standard of commercial shrimp. Generally, male shrimp grows faster than female shrimp, and commercial shrimp The size is also larger than the female shrimp. ...
