Can cucumber seedlings be eaten?

Yes, paying attention to scientific farming can grow so long and so fast!

Breeding method:

Feed-fed loach has a variety of eating habits, and small animals, plants, microorganisms and organic debris in the water are all its favorite foods. Artificial feeding should also be fed with animal feed such as maggots, earthworms, small miscellaneous fish, mussels, fish meal, livestock and poultry leftovers, and plant feed such as wheat bran, rice bran, bean dregs and cake meal.

Regular, fixed-point, qualitative and quantitative feeding. The feeding amount depends on water quality, weather and feeding conditions. When the water temperature is suitable, feed it once a day in the morning, at noon and at night, and once a day in the morning and evening when the water temperature is low. The percentage of feeding amount to the body weight of pond loach: March1%~ 2%; From April to June, 3% to 5%; July-August10% ~15%; In September, 4%. The feeding ratio of plant feed and animal feed at different water temperatures: when the water temperature is lower than 10℃ or higher than 30℃, feed less or not; Water temperature 1 1 ~ 20℃, plant feed accounts for 60% ~ 70%, and animal feed accounts for 30% ~ 40%. The water temperature is 2 1 ~ 23℃, and the plant feed and animal feed account for 50% respectively. The water temperature is 24 ~ 29℃, plant feed accounts for 30% ~ 40%, and animal feed accounts for 60% ~ 70%.

Water quality management After loach stocking, topdressing should be done in time according to the fatness and thinness of water quality, and plankton should be cultivated to keep the water fresh and cool all the time. When the water temperature reaches 30℃, replace fresh water in time and increase the depth to reduce the water temperature and prevent floating head. It is found that loach often swims to the surface and swallows, indicating that there is no oxygen in the water, so fertilization should be stopped and fresh water should be injected immediately. During the wintering period, it is not necessary to feed loach from 65438+February to February of the following year. It is only necessary to increase the depth of the pond, put pig manure in the corner of the pond, raise the water temperature, and ensure the safe wintering of loach.

Daily management patrol the pond once every morning and evening to check the activities, eating and diseases of loach. At the same time, observe whether there is leakage in the culture pond and whether the loach escapes. Cement ponds should be cleared of residual feed every day.
