How much does rice worm cost per jin? A detailed explanation of the key points of breeding technology
When it comes to rice worm, many people are completely confused and have no idea what it is. In fact, it is a kind of annelid called Tylorrhynchus heterochaetus, and its appearance is somewhat similar to a centipede, but it is an aquatic animal. Rice worm is mostly seen in the Jiangsu and Zhejiang area, where people treat it as food. They not only fry it, but also use it to make soup. It is said that the soup made from it is very fresh, delicious and smooth. Would you dare to try it? Let us take a look below at how much rice worm costs per jin and what the key points of breeding technology are.
1. How much does rice worm cost per jin?
The price of rice worm is relatively expensive, and it even sells for as much as 80-150 yuan per jin at the vegetable market, but there are still quite a few friends who buy it to try something new, especially people in the Jiangsu and Zhejiang area.
Because the rice worm is 3 to 4 cm long, its outer skin color is golden yellow with a little red mixed with green, and the worm body is relatively plump, full and containing fluid, and it moves relatively slowly. Its appearance is rather frightening. Although people very much love to eat it, they do not dare to make this delicacy themselves. Many people choose to taste it in restaurants, but ordinary restaurants around here do not have it.
It is understood that rice worm belongs to the “green food” that everyone pursues, and it is deeply loved by food lovers. Rice worm is generally relatively high-yield in the ninth and tenth lunar months, and its quality is also relatively good. Especially around the first day of the ninth lunar month, the output of rice worm generally accounts for the whole year's percent discrimination. So how do you catch rice worm? Usually you have to choose when the hydrology and weather are very suitable, so that rice worms will leave the rice roots one after another and float together on the water surface.
2. What are the key points of rice worm breeding technology?
1. Establish a rice worm seedling site
If you want to breed rice worm, you first need to establish a rice worm seedling site, which can be divided into two parts: a canopy and a breeding ground. The top of the canopy should be built with film and shade net materials, and breeding troughs should be built inside the canopy.
Choose suitable mud. Generally, the mud from the surface layer of rivers and creeks is good. After choosing it, fully filter it, place the filtered mud in the breeding trough, and at the same time adjust the salinity and alkalinity.
2. Select seed worms for fertilization
Pour already filtered water into a plastic box, and place one oxygen pump in each plastic box to ensure sufficient oxygen.
Generally, only male and female worms with bright colors, plump bodies, robustness and no injuries can be used as seed worms. Then place the selected seed worms in the plastic box filled with water so that they naturally fertilize.
3. Feeding key points
Wait until the larvae of the rice worm grow to the three-segment worm stage, then feeding should begin. When worm holes of the larvae are found in the soil, the water in the breeding trough can be drained, and then the prepared food can be scattered on top of the mud for the rice worm to eat. Then on the second day, put the filtered water back into the breeding trough. After a little more than half a month, they will have been cultivated and can be placed in rice fields for breeding.
