When the male and female hens naturally mate, the vaginal mucosa of the hen is everted and has susceptibility. The cop's copulatory organs are at the end of the vas deferens and consist of a cloacal mucosa that can be filled with lymph and slightly erect. The cock projects a part of the semen, adheres to the hen's cloacal mucosa, then enters the vagina, and ascends to the infundibulum following the peristalsis of the goblet cells of the fallopian tube. When there is no egg in the fallopian tube, and the sperm is ascending, it takes only 30 minutes to reach the infundibulum of the sperm, where it is stored and a sperm is combined with the egg cell to form the fertilized egg. During the day, male and female cocks mate more often in the afternoon, and hens produce fertilized eggs approximately 20 hours after cooping with the rooster. In the flock, the fertilization rate is generally reached approximately 3 days after the beginning of breeding. After separation of male and female hens, the proportion of fertilized eggs decreased every day, and the rate of decline after 4 days to 5 days accelerated. Breeding age and age The cocks showed primary spermatozoid cells in the testis of 6 weeks old, secondary spermatocytes were present at 10 weeks of age, secondary spermatocytes at 12 weeks of age divided into sperm cells, became spermatozoa, and reached sexual maturity at 20 weeks of age. After 22 weeks of age, it is possible to breed, in order to obtain a higher fertility rate. The fertilization rate of male and female hens is too low for premature mating. Only when the male and female hens are in the same period of sexual activity, the fertilization rate of eggs is the highest. The rooster is used for mating from 22 weeks of age and can be used until 72 weeks of age, and its fertilization rate does not decrease. The rooster can be used for 3 years. The hens were bred and bred from the 26-week-old hens and reared for another 48 weeks. Within this age range, the fertilization rate of eggs can be as high as 86.3%. Excellent breeding hens can be used for 2 to 3 years. Male and female breeding ratio In the naturally mated flocks, the proportion of males and females directly affects the fertility rate of the eggs. Large size, older roosters, and fewer hens. The weight is light and the cock is healthy. It is in a period of sexual activity and can be equipped with more hens. In the summer, fewer hens are needed, and one cock in the fall, winter and spring seasons can be properly equipped with hens. Appropriate proportions are: light layer hens, 1 cock with 12 to 15 hens; light and heavy hens, male to female ratio should be 1:10~12. The hens' egg production is mostly concentrated between 9:00 and 13:00, accounting for 70%-80% of the total egg production, and less eggs are produced in the afternoon. The most frequent time for male and female mating activities is after the majority of hens lay eggs on the day, that is, between 4 and 6 in the afternoon, males and females have the highest number of matings. 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.

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.
