Orchard winter irrigation strong trees increase production
Winter irrigation in orchards can increase soil moisture content, prevent spring drought, improve the cold resistance of fruit trees, so as to ensure safe wintering; accelerate the decomposition of organic fertilizers and facilitate the absorption of soil nutrients by roots; also effectively reduce the freezing damage and prevent wind erosion. Wait. The technical points are: 1. Winter irrigation time. It is better to harvest the fruits before the soil is frozen. Winter irrigation is too early, the temperature is still high, evaporation is large, is not conducive to water conservation; late, when the temperature is lowered, the soil is frozen, the water is not easy to infiltrate, the water freezes, the roots of fruit trees are vulnerable to frost damage. Generally, when the temperature is 3°C and the average ground temperature reaches 5°C in a 5 cm soil layer, the winter irrigation is most suitable when the topsoil is at night. 2. Irrigation. The amount of water that is poured into the winter should be fully absorbed by the water on the day of irrigation, and the root distribution layer (40-60 cm) should be soaked. After the irrigation, the soil moisture is maintained at 60%-85% of the maximum water capacity in the field. 3. Irrigation method. In orchards with good water sources and well-watered irrigation facilities, furrow irrigation or ring-shaped furrow irrigation can be used. In orchards with poor water sources and facilities, discoid soil can be sprayed around the outer edge of the canopy. Orchards with good conditions can also use drip irrigation or sprinkler irrigation. Regardless of the method used, if a suitable amount of decomposed human excreta can be applied before irrigation, the effect will be better. 4. Management after irrigation. After the winter irrigation, if the entire garden ground coverage can be achieved, the water retention and antifreeze effect will be better. Straw, wheat straw, rice hulls, wheat bran, weeds, etc., are all good materials for gardening. The straw should be cut into short sections of about 10 cm and sprinkled with large earth blocks to suppress the wind. If there is no coverage, when the person enters the park after irrigation, the surface of the earth can be raked shallowly to loosen the topsoil and cut off the capillary to prevent or reduce the evaporation of water. 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.
