Huang Hao's Holding-up Fertilizer Technology

Huang Hao's Holding-up Fertilizer Technology

The seasonal price difference of Huangqi is relatively large. In the summer, the price of the same specification Huangpi is usually only half of the selling price in winter and spring. Summer and autumn harvesting of Astragalus membranaceus will be used as a fattening fertilizer, and it will be possible to achieve better results by selling at high prices around the Spring Festival.
1. Preparation for holding tanks. The selection of holding pools can be adapted to local conditions. Cement pools and earthen ponds can all be used. The cement pool is going to alkali, and 30 cm of loam is laid on the bottom of the pool. The earthen ponds are to be laid in the bottom of the pool, and the woven fabrics at 0.5 cm are free of netting and stepped into the bottom of the pool. The holding pool area should be 20 to 30 square meters. In order to prevent the heatstroke, you can transplant water peanuts and water lotus in the pool, build shading facilities above the pool, filter in the pool, and pollute the river about 30 centimeters.
2. Carp stocking: When the carp market price is low, it is possible to stockpile the non-injured and robust Huang Bachi, and generally stock 5 to 8 kg per square meter. There are three issues to keep in mind when stocking: each, specifications. To keep the size of the different specifications of the yellow oysters pooling. Second, disinfection. Because the surface of the skullcap is not scaled, the conventional salt and bleaching powder easily make the jaundice debonded and should not be used. If surface disinfection is necessary, it can be treated with low concentrations of chloramphenicol and furazolidone. Third, polyculture. To prevent jaundice from intertwining, it is necessary to mix 10% of the loach. In addition, in order to prevent disease, a live larva is stocked in every square metre of the pool.
3. Holding management. After stocking, Huangpi must do a good job in three aspects: First, dispel the intestinal parasites in the body of Astragalus. Generally available human drug "intestinal clear" mixed bait feeding. Second, ensure food supply. Astragalus is very picky on bait. When feeding, fresh quails mainly feed 5% to 10%. From this point of view, it is very important to cultivate a large number of earthworms before raising the eel, which should arouse the attention of farmers. Third, change the water. In the hot season before October, water changes are needed every 5 to 7 days. After October, change the water every half a month. When changing the water, drain the old water from the pool. Pay attention to the refreshing river water and keep the water temperature as close as possible. It is best not to add oxygenated tap water.
4. Late management. When the temperature drops below 10°C, the yellow locust will stop feeding and you can stop feeding. If the temperature dropped to 1 °C ~ 2 °C, appropriate water injection or tower insulation facilities to prevent frostbite Huangpi. Before and after the Spring Festival, depending on the market price, the yellow cricket will be sold for sale. At this time, after 4 to 5 months of storage, the fertilizer can be profited from 15 to 20 yuan per kilogram of astragalus.
