How to select the species of rice flower fish? How to breed better

In the documentary "China on the Tip of the tongue", glutinous rice and fish show off their elegant demeanor, making people can't stop drooling. So, what on earth is the rice flower fish that we rarely see? Rice flower fish does not specifically refer to some kind of fish, but the product of rice-fish symbiotic system, mainly carp and crucian carp. The symbiosis of rice and fish, as the name implies, means growing rice and raising fish. Rice with fish soup makes you drool when you think about it.

First, the advantages of rice flower fish

Why should fish and rice be raised together? In the process of growing, fish can eat plankton and pests in rice fields, and fish excreta can also provide nutrients for rice. In this way, the use of pesticides and chemical fertilizers is reduced, and it is green, safe and economical. Moreover, rice and rice cauliflower fish are produced in the same rice field, which is the two incomes, which has made no small contribution to the increase of farmers' income.

Second, the selection of rice flower fish

Generally speaking, we prefer carp and crucian carp to cultivate rice flower fish. Why? Because the vitality of carp and crucian carp is tenacious and omnivorous, they can well adapt to a variety of growth environment, so we don't have to worry too much about fish production when we breed rice flower fish. Other fish, on the other hand, eat grain seedlings, resulting in a lower yield of rice.

III. Culture of rice flower fish

1. In the selection of rice, we should choose varieties with strong stalk, fertilizer tolerance, strong lodging resistance and high yield, so as to ensure the yield of rice. The water level of the rice field should not be too high, otherwise it is easy to affect the growth of rice. It is recommended that the best water level is about 15 cm, which is suitable for both rice and rice cauliflower fish.

2. The stocking of fish fry is later than the time of transplanting seedlings. Sow rice in March and April, start transplanting rice seedlings at the end of April, and release fish fry at the end of May. The number of fish fry should not exceed 300. According to the state regulations, the proportion of ditches can not exceed 10% of the planting and cultivation area, and can not affect the yield of rice.

3. I mentioned earlier that rice cauliflower fish will eat plankton and pests in rice fields, but it is not enough to make rice cauliflower fish grow well. Fish fry should be fed once or twice a day. The bait should be based on biogas residue and green organic matter, so that it can not affect the growth of rice, but also take into account the nutrition of rice flower fish.

4. Be cautious about the use of pesticides. If the pesticide is sprayed too much, it is very likely to lead to the death of a large number of rice cauliflower fish, so the loss outweighs the gain. Therefore, when releasing fish fry, it is necessary to do a good job in weeding the farmland and reduce the carriers attached to diseases and insects. In case of disease and insect disasters, do not choose toxic pesticide spraying, try to ensure the healthy growth of rice cauliflower fish.
