Duck ponds, ducks and fishes (ie, underwater fish farming, water surface ducks) are an ecological farming model promoted in recent years, it has the following advantages: (A) Fish pond ducks can be fish aerobic fish Growth requires enough oxygen. The ducks are active, floating on the water, washing and playing. On the one hand, the air can be directly pressed into the water, and on the other hand, the upper saturated oxygen dissolved water can be stirred into the middle and lower layers, which will help to improve the dissolved oxygen in the middle and lower layers of fish ponds. situation. In this way, it is possible to dispense with the use of live water or installation of aerators. (B) will help improve the ecosystem of the fish pond nutrition environment Fish ponds due to long-term fertilization, feeding and pond fish continuous excretion, easy to form bottom sediments. Most of these sediments are organic matter. Ducks constantly stir the pond water, which promotes the decomposition of these organic materials, accelerates the spread of organic debris and bacterial aggregates in the mud ponds, and provides more fish for the fish. (3) Ducks can provide superior bait for fish. Duck dung has not only a large amount of unabsorbed organic matter, but also contains more than 30% of crude protein and is the top bait of fish. Even if the duck dung cannot be consumed directly for the fish, it can be decomposed by bacteria to release inorganic salts, become a nutrient source for plankton, promote the reproduction of plankton, and provide baits for alfalfa and cockroaches. (D) Prevention and treatment of duck parasites Ducks are omnivorous poultry, which can timely feed the dead fish and fish body lesions floating in fish ponds, thereby reducing the spread of pathogens, ducks can swallow many fish predators Such as otters, etc.; ducks can also eliminate moss and algae that grow due to the lack of thoroughness in clear ponds; there are ducks in fish ponds, and harmful water birds do not dare to land on the water; ducks swim and wash feathers to make them parasites and The skin is shed in the water and eaten for the fish, which reduces the infection of the parasites in the duck itself. No matter what kinds of fish ponds use ducks, fish should be the mainstay. There are three main ways to combine fish and duck: 1. Direct polyculture. Mesh the inside of the fish pond dam or the corner of the fish pond, around a semi-circular duck canopy, as a duck farm activity or activity pool. The side of the duck shed facing the fish pond should have a spacious shed door to facilitate the launching of ducks, and it is also convenient to clean the dung shed and the faeces on the activity field to enter the water. Some fish ponds with large water surfaces and a large number of ducks may not be added. Fence. 2. Pond outside ducks. Leaving Tangchi, a larger duck shed is set up near the fish ponds, and there is a playground and activity pool. The arena and the pool are all cement surfaces for easy flushing. The duck dung and feed residue from the activity site are swept into the fish ponds every day. Every day, the fertilizer from the active pool is poured into the fish ponds and the new water is poured. 3. Raise the duck. Overhanging fish ponds and ducklings are used for small-scale production. The benefits are obvious. The specific method is: piling on the fish ponds, scaffolding, sheds, shed more than 1 meter above the surface of the water; the shed is surrounded by a mesh sheet, the shed is covered with bamboo sheets or nets with a mesh size of about 3 cm and 3 cm. It is advisable to be able to leak duck dung and duck dung not to step on the empty. With this method, ducks are rushed to the nearby river for a period of time every day.
Foot of ningxia hong xingda incense Organic Apple fruit suborbicular, fruit surface color yellow green, most with orange chardonnay fruit surface, covered with bright red stripes, pulp yellow-white, succulent crisp, sweet, rich fragrance, quality first-class; The fruit has a sugar content of over 15%, more than 4% of the national average, and the flesh is tight and crisp and sweet, which is widely loved by consumers all over the world. There is a longer optimal consumption date than any other apple, not even refrigerated. It can be kept for 4 months at normal temperature. If refrigerated, Fuji can be kept for 5--7 months.
Altitude: high altitude area light, clean air, environment close to original condition, no industrial pollution. With an average elevation of 1160-2900m, the central health center has a strong uv light, which produces the natural pollution-free apple, which conforms to the concept of a modern green diet.
Temperature: moderate temperature can avoid the chance of fruit tree encountering disease. The average temperature in ningxia is 8.4 degrees Celsius, which has an important influence on the growth, development, yield and quality of apple. The piedmont apple is thriving in such a good environment.
Humidity environment: moderate amount of rainfall provides necessary conditions for apple's growth. The annual rainfall in the central health region is 186 millimeters. The fruit is slow to grow and the fruit is hard and hard, which fully guarantees the fruit's sugar content and the relatively average size of apples.
Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
