First, technical points 1. The land for seedbed selection must be selected without overgrowing the onion, otherwise the rate of dead seedlings of wintering seedlings will increase, which is unfavorable for maintaining seedlings and increasing yield; 2. The sowing date of greenhouses is from August 1 to August 5, and the seeding rate is: 85% or more of the seed rate of 17 kg/mu. The seedling sowing period of the earth is from August 5 to August 10, sowing rate: 85% of the seeds with a bud rate of 15 kg/mu. Save the cost of building a shed or renting a shed; 3, spraying seeds and spraying water after seeding, eliminating the need for manual weeding costs; 4. The standard of raising seedlings is 6 to 7 mm in leaf sheath diameter, and 4 to 6 g fresh weight per plant is a suitable size seedling. When the seedlings reach the raising standard, they can be raised and stored. 5. The over-winter seedlings were selected to have no onion land and watered 4 to 5 days before the ditch was stored to make the soil moist. After the seedlings are planted, the seedlings are planted with a planer ditch. The length of the seedlings is 80% of the length of the seedlings (the heart must be buried), the seedlings are 2 inches thick, and a thin layer of straw curtains (sun protection leaf) is applied on the seedlings. When the soil is frozen one foot deep, the straw curtain is thickened to more than 1 foot thick. After clearing and clearing, remove the straw curtain when thawing. When the temperature is appropriate, it is planted on the earth (in mid-April). Second, winter and spring seedling contrast 1, without the shed film, labor saving, labor-saving due to winter seedlings nursery period in the period of 8 to 10 months, the temperature is enough, no insulation treatment, so save the cost of renting a shed or building a shed. According to rent, the average cost per mu is 100 yuan less than that for spring sowing, and labor and labor are saved. 2. The cost of manual weeding in the province's seedbeds can be sprayed by wintering seedlings after seeding, eliminating the expense of manual weeding due to inability to spray herbicides on spring seedlings. The average cost of acres is 30 yuan less than that of spring sowing. 3, the provincial planting seedlings when the cost of winter seedlings planting time is early, missed spring planting time when the planting season, planting labor costs than artificial seeding each spring to reduce 20 to 60 yuan. The average cost of acres is 29 to 87 yuan less than that of spring sowing. 4, high selling price, more money left Due to the high selling price of onion during wintering period, the average price per catty is 0.03 yuan more than that of spring sown onion, and the average yield per mu is 210 yuan, which is 7,000 pounds per mu. 5, high yield, more selling of winter over onion than the spring sown onion yield of about 10%. According to the spring planting of 7000 pounds of onion per mu, the onion average of 0.4 yuan per kilogram, the overwintering effect of onion mu is 280 yuan higher than spring onion. 6. Overwinter seedlings The onion is of good quality due to overwintering onions, drought resistance, and resistance to pests and diseases. It can fight drugs and reduce the amount of drugs. Therefore, compared with spring sowing and onion cultivation, it saves labor costs, reduces drug costs, and improves product quality. The cost is 20 yuan less than that of spring sowing onions. 7, harvest early, sell well for overwintering onion harvest in late July to early August, 1 month ahead of spring sowing onion harvest, can catch up with a good price, so as to ensure stable income, more favorable to interplant other crops, so that interplanting The high and stable production of crops will help improve the benefits of overwintering onions. In short, from the above analysis, it is concluded that the benefits of overwintering seedlings are at least 669-727 yuan more than the spring seedlings. Therefore, the technology for wintering seedlings has a strong advantage and has great potential for development. It is expected to be rapidly popularized in the next few years, so long as the wintering seedling raising technology and the spring sowing seedling raising technology are used in a reasonable manner to make the two techniques of onion harvesting. Interspersed with open, it can better play onion price advantage, so that onion this "golden industry" to bring greater economic benefits and social benefits to the majority of farmers. 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.
