Post-harvest management do a good job throughout the year to win
To enable a large number of ponds to multiplication of natural food organisms, the need for timely applied fertilizer, as water temperature decreased gradually, should be splashed in the shallow pool of manure fermented in order to speed up the process of dressing the water. Is strictly prohibited without the fermentation of fresh manure application to prevent contamination of fresh fecal bacteria in the water. Fish ponds fertilization Note: (1) a variety of fertilizers, their nature, the speed of fertilizer, the size of fertility, fertilizer source, the level of economic value are not the same. Is the same kind of fertilizer, but also because processing preservation method,[link widoczny dla zalogowanych], time and different application methods vary considerably. Therefore, carefully consider the above before fertilization factors. (2) the specific pond fertilization time, method of fertilizer fertilizer according to the three, put the wheel catching round high stocking density of large fish ponds, still adopt a there is a reasonable density, so that the full growth of the small size of fish to ensure a balanced fish market. At this point the water temperature is still high, strong fish activity, oxygen consumption, oxygen water often, so fishing time can not be sustained for too long, should be carried out before 7 o'clock in the morning. Before the fish was found floating head a serious phenomenon, it can not be pulling the nets, to prevent the pan dead fish pond. Fishing after the infusion of fresh water into the pond to start the aerator or aeration, restore fish living environment. At this point according to fish growth needs to maintain maximum water storage capacity, it is best to add new water once a week, when the water is too full to discharge the underlying water. Fourth, the fall and grass pasture management a good month or season, can take advantage of wasteland cultivation of perennial ryegrass ridge pool. Timing of planting in the White Dew, the per mu of about 1 to 1.5 kg seeding, sowing the seeds mixed with ash or fine sand, or on-demand drill sowing method. After sowing, watering, usually 5 to 7 days to germinate. Ryegrass in the seeding is also Sudan grass seed harvest when the seed tender cooked to distinguish the degree of serious collection, to prepare for planting next year. Also available to increase income. Mix ratio, the effect is good. Fertilizer N, P and K were 09 g / m 3,09 g / m 3,0.45 g / m, can also be inorganic fertilizer and organic manure mixed or used interchangeably, and thus the advantages of both integrated and mutually add. Second, feeding Sept. moderate temperature, grass carp and other food consumption has not decreased, it is a good time fattening, food ration must be sufficient. Fed diet still adhere to the feeding, growth and fattening affected. This month decreased dry grass, then add fish to feed on the fine cast is very important and appropriate to add some high protein content of the bean class feed. Larger temperature difference between day and night this month, feeding time should be adjusted in the morning can be a little later, at 8:30 --- 9: 30 pm the appropriate number in advance, preferably in the 15:00 to 16:00. Uneaten feed to promptly remove or replace. Overall, fertilization, feeding the process must master the . Adult fish reared at the same time to strengthen, but also to grasp the final stages of fish cultivation,[link widoczny dla zalogowanych], cultivating robust large-sized seed in autumn flowers. And take into account the cultivation of broodstock, chasing fat, to facilitate normal winter. V., prawns, crabs shrimp and crab breeding ponds based water quality management, to quiet, dissolved oxygen rich. Shrimp and fish on the water quality higher than required, water pollution sensitivity of post-harvest management of a greater whole,[link widoczny dla zalogowanych], if the crabs found in the pool,[link widoczny dla zalogowanych], corruption of oxygen or water, the water in time for the new note. Water exchange time in the sunny afternoon, rainy days the middle of the night to change the water before dawn, to prevent the crabs hypoxia. Can also be taken regularly spill lime water, photosynthetic bacteria, zeolite powder and the way to improve water quality. Often measured pH, to maintain slightly alkaline. Night and early morning every day a personal Xuntang, good Fangtao, security, disease prevention work. Found Fangtao shall promptly repair damaged facilities and found that organisms are to be promptly removed predators, to timely diagnosis and treatment of sick crabs. (1) month,[link widoczny dla zalogowanych], a bacterial sexually transmitted diseases crustaceans: Sickly abdominal appendages rot or anal irritation, causing loss of appetite, poor feeding. Can be 0.5 to 1 g / m oxytetracycline disinfection, has a certain effect. (2) protozoan disease: a large number of epiphytes in the crabs Condensation surface insects, worms and other single-reduction, will affect the normal activities of shrimps and crabs and feeding. Available 5 ~ 1O ml / m formalin whole pool disinfection. The drug had no effect on the growth of prawns and crabs, another ice fish fed the fish farmers have to pay attention to the ice after minced with povidone-iodine and other iodine-containing agents fed after immersion disinfection to prevent transmission of the disease.
