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.
Artificial culture of snails
The artificial breeding technology of the snails is named Fangbandongfeng snail, aliased to small wind snail, sea snail, Dongfeng snail. It has a deep thread and long oval shell; shell surface is smooth, shell is slightly thin, shell surface is light brown shell skin, shell skin is mixed with white, dotted or rectangular purple brown or reddish brown plaque. The general shell is about 70 mm high and the shell is about 40 mm wide. Usually like to live in the clear water, rocky or sandy harbor area, some hi habitat in the depths of several meters or tens of meters deep. The snails are broad-brimmed benthic gastropods, and the diets are mainly animal flesh or algae and debris. It is a kind of high-quality and economic seafood shellfish, which is delicious, tender and refreshing, nutritious, has high food value and economic value. The market price of snails on the Guangzhou market has increased from 96-110 yuan per kg in 2002 to the recent 116-120 yuan. The vast number of hotels and restaurants are in short supply, especially in Hong Kong, Macao and Taiwan, and can be sold in large quantities to Japan and South Korea. . At present, domestic farming has not yet been carried out on a large scale, and there have been a few scientific research units and seedling farms in the western part of the country to carry out artificial breeding and breeding. The technology of the snail breeding is introduced as follows: The snail is suitable for the growth of sandy or sandy mud, stone seams, etc. The survival temperature is 3°C--38°C, the optimal growth temperature is 25°C--33°C, the specific gravity of seawater is 1.015-1.023, and the salinity is stable, the dissolved oxygen requirement is greater than 3 mg/L, and the pH value range is Between 7 and 9, the best is 7.5--8.5. Usually lurking in the surface layer of sand and mud, when smelling the smell of food, that is, crawling out of the sand to scrape the food with tongue teeth in the water pipe, the food is larger and grows faster. Its feeding methods can be adopted in pond culture or beach purse seine culture. 1, pond culture. According to habitat habits, the pond is made slope type, the bottom of the pool is sandy, such as mud bottom should be sanded 5-10 cm; sea water quality should be clear, muddy water should be filtered through the clarification into the pool, stocking density: extensive For 80--100 grains / square meter, intensive breeding pool is 160 --- 200 / square meters, the size of 0.5-1 cm young snail is appropriate. After stocking, the water quality should be kept relatively stable, mainly because the transparency and salinity of the water can not be changed very much. The feed is fed with fresh fish or fish paste every morning and evening, and special shellfish compound feed is also available. The amount of feed is generally the flower 3% to 5% of the snail's body weight. If the water quality is fat and the water color is dark, then it will be less cast. If the water is thin, it will be cast more, and the feeding amount will be controlled flexibly to avoid causing pollution to the beach. Snails are fast-moving, have a large range, and should be fed and fed as far as possible, so as to prevent the flocks from ingesting food and lack of oxygen. The water depth of the farm pond should generally be about 60-100 cm, and it can also be polycultured with shrimp, fish and other shellfish under conditions. If intensive culture should have aeration systems or microfluidic aquaculture, keep the water fresh. A nursery pond with a cement structure was selected and sanded to the bottom by 3--5 cm, which can also be used for snail breeding. The snails are cultured by artificial feeding at room temperature and cultivated for 3 months to catch large and small animals. Gradually, they are listed on the market. The general market specifications can be 120--160/kg, or they can be cultured to 20-40/53 kg. Listing. Specific listing according to market size and size requirements. Conch farming usually can be reared for one year and the breeding period is from early May to late July, early August and late October. The year of breeding can be harvested, and the survival rate can reach 95% or more. 2, fence farming. The beach is required to have fresh water, small wind and waves, sandy bottom, and aquaculture. The net should be more than 0.5 meters above the tide level, and the mesh should be selected according to the individual size of the snail. Because the snail crawls quickly, it is easy to climb through the net and escape, so it should have a certain height of the fence. After the fence is completed, it is necessary to carry out hoeing and trenching on the painted surface, remove the hostile creatures, and use the “clear pond net†or high. Concentration "bleaching powder", "lime" can be, killing after about a week to clean up the seedlings, generally 50 ~ 100 per square meter Fangmiao volume, usually managed to check the escape, repair network, clear The main pollution is to feed fresh fish and shrimp every day. The disinfected surface is generally disinfected once a week or a half month. It can be disinfected with “bromochloroheine†or “dibromohydantoin†to prevent bacterial infection. During the later period of culture, attention should be paid to the growth of the snails, and attention should be paid to changes in the bottom coat quality, air temperature conditions, and wind direction to prevent the collective escape of the snails, especially during the typhoon season, and pay attention to the reinforcement of the fence columns. When there is excessive silt or dirt on the beach, it should be promptly cleared to prevent loss caused by pollution. In particular, breeding season should pay more attention to disease prevention. Harvesting can also be harvested to stay small, or all harvested and harvested for sale.
