In recent years, with the rapid development of artificial breeding of Astragalus, the contradiction between supply and demand for large-sized Astragalus seedlings has become increasingly prominent. To this end, the author introduces four methods for raising seedlings for reference by the farmers.
The fertilizer cultivation method utilizes skilled human and animal manure to cultivate natural live baits for feeding by seedlings. From the second or third day before the seedlings enter the pool, the composted manure is applied to the pool once a day for 150-200 g per square meter of surface water. Or 80 to 100 grams of human fecal urine per square meter of water, filter the fecal residue and add water to dilute the entire pool. The disadvantages of this method are: the fertilizer is rotted and decomposed in the pool, and it is easy to pollute the water and lead to lack of oxygen in the pool water. Therefore, water quality regulation and management should be strengthened.
The feedstuffs for feedstuffs should be soymilk, because soymilk is rich in nutrients. Soybean milk leftover from the seedlings can be used directly to make water and fat, and the pool water can become fat and keep the water stable. Soybeans 1.2 to 1.5 kg, soaked in warm water at 25 °C for 5 to 7 hours, then add 20 to 25 kg of water, ground into a slurry. Then the grinded pulp was squeezed out of the bean dregs with a squeeze bag and the juice was spilled. Soybean milk should be freshly ground and splashed, and the whole pool should be splashed evenly, so that it can be as fine as fog and uniform as rain, and it can take small meals. Soybean milk cultivating seedlings generally consumes more material and costs more. According to the lack of nutritious live baits in the first few days of seedlings entering the pond, in order to complement each other, it is possible to adopt methods combined with bait cultivation. That is, 5 to 7 days before the seedlings enter the pond, 10 to 15 grams of manure is applied per square meter of water to cultivate natural food. A few days after the seedlings enter the pool, 5 to 10 grams of soymilk per square meter of water is poured every day to make up for the lack of natural food. Afterwards, 10 to 15 grams of fertilizing material per square meter of water will be applied every 3 to 5 days. If the seedlings enter the pool, the water quality is not fat and there is not enough food to feed more milk. When the pool is rich, stop spilling soymilk. In case of cloudy days, low temperatures, and slow decomposition of fertilizers, feed more appropriately.
Large grass cultivation method In the five days before the seedlings enter the pool, 150-200 g grass (non-toxic and harmless fish with forage grass) and 10-15 g quick lime are put into the mud at a ratio of one meter per square meter, and then 10 cm is laid. Thick grass, sprinkle about 3 cm thick quicklime on the grass, and then flip 2 to 3 days 1 time, and the residue cleared out of the pool in time. After the seedlings enter the pond, the grass should be magnified at the pool corner in a timely manner according to the water quality, so as to maintain the appropriate fatness of the pool water.
Grass pulp cultivation method adopts straw pulp to cultivate seedlings, which not only facilitates material withdrawal, but also saves a large amount of fine material and reduces production costs. The method is: using easy-to-digest water grass, such as water peanuts, water lettuce, etc., after adding pulp, add 3% of the weight of fresh grass salt, place 8 to 12 hours will be Quanchiposa feeding seedlings. The finer the grass pulp is, the better it is. The purpose of adding salt is to remove the saponin from the water peanuts. The salt seedlings will not be eaten without salt.
No matter which cultivation method is adopted, the quantity and frequency of feeding and fertilizing should be controlled flexibly according to the conditions of the water, fat, weather, and seedlings. As the seedlings grow up, some bean flour or fine rice bran may be properly fed. At the same time, put some duckweed or water lotus in the pool.
