In April, the temperature rose, but the amplitude was relatively large and the water temperature was not stable. The main fishing activities were as follows:
First, do a good job of breeding fish. It is understood that most of the fish farmers in my county have already prepared for the breeding work. Hu Yuandi, a former village in the previous town, has pulled a “fishing dragon†from the mountain to do a fish nest, and he intends to artificially breed after the weather has improved. The fishery households in the northern mountainous areas such as Handan and Yingkeng are actively preparing. It is expected that the artificial breeding of Tianyu will peak in mid-April.
Second, do a good job in field fish seedling training. Seedlings are the basis for aquaculture production. It is understood that fishery species in paddy fields are generally insufficient, and the use of field fry seedlings is an effective method to solve the problem of the source of fish species. Farmers around the country can choose suitable cultivation of farmland for seedling cultivation, which can meet their own needs, but also to foreign Sales, paddy field cultivation costs low, high efficiency.
Third, strengthen the feeding and management of adult fish. As the water temperature rises, it is necessary to gradually increase the feeding amount of the adult fish. Farmers can feed on the breeding waters of Tiantang, Shantang, and small reservoirs in accordance with the "four-determining" feeding principle to ensure that the adult fish eat and eat well. Eat well.
Fourth, regulate water quality and strengthen fish disease prevention. As the water temperature rises, various diseases will also increase. The fish will raise water first and do water quality adjustment work. This is an effective method to prevent fish diseases. Water quality can be adjusted by using quicklime (30g/m3 water) or photosynthetic bacteria (0.3-0.5g/m3 water) alternately, once every half month, to kill pests and diseases, focusing on watery mildew, parasitic diseases, Bacterial fish disease prevention ensures safe breeding.
Fifth, do a good job in the construction of fishery infrastructure and enhance the potential for production. For fish farming in rice paddies, construction and maintenance of fish pits and cement fields should be done in a timely manner; Shantang Reservoir should be equipped with fish-prevention facilities to prevent fish from escaping; other projects are subject to specific circumstances, and they can not be launched at present. You can stay in the second half of the year to prevent blind projects. In addition, fishery machinery such as aerators and feeders can be added according to production needs, and the level of fishery equipment can be continuously improved.
Sixth, add fish species in time. Some time ago due to heavy rainfall, some of the ponds have not yet been listed for catching fish. If the catchment is launched in April, it is imperative to implement a good fish species plan to prevent shortages of wasteland. All kinds of fish ponds that are not stocked properly should be filled with fish in a timely manner so as not to affect the breeding efficiency of the year.
Adult diapers are disposable urinary incontinence products, one of the adult care products, and a disposable diaper mainly suitable for incontinent adults.
Most products are flaky and shorts type. Use adhesive sheets to connect into a pair of shorts. The adhesive sheet also has the function of adjusting the waist size so as to fit different fat and thin body shapes.
Generally, the structure of diapers is divided into three layers from the inside to the outside. The inner layer is close to the skin and made of non-woven fabric; the middle layer is water-absorbent fluff pulp, added with polymer water-absorbing agent; the outer layer is an impermeable breathable film.
