Jujube trees have a long flowering period, flowering, and large consumption of nutrients. If they are improperly managed, they will cause a large number of flowers and fruits, which will lead to a reduction in production. Therefore, in the jujube tree flowering and fruit preservation, can significantly increase production, the following management measures should be taken.
First, foliar fertilizer application in the initial flowering period with 0.3% ~ 0.5% of urea solution for foliar spray, in order to improve the quality of bud differentiation. In the flowering period and young fruit period, spraying with a mixture of 0.3% urea solution and 0.4% potassium dihydrogen phosphate solution can reduce flowering and fruit drop, increase fruit setting rate, and increase fruit weight. , improve the quality of dates.
2. Spraying growth regulators and trace elements during the flowering period Giving a concentration of 1010-4 gibberellic acid or 2% chlormethasol solution and 0.2% zinc sulfate solution can effectively improve the fruit setting rate of jujube trees.
Third, flowering girdling jujube trees that have entered the full fruit period and are 12 to 15 years old are girdled during the flowering period. Method: On the jujube tree trunk about 15 centimeters from the ground, use a sharp knife to cut 2 circles, and the width is 4 to 6 millimeters. It is better to reach the xylem and peel off the skin. The girdling is carried out once a year, gradually girdling upwards from the base of the trunk, every 3 to 5 cm. The privilege must grasp the principle of non-peeling, that is, small trees are not stripped, weak trees are not stripped, and they are not stripped during the period of circumcision.
Fourth, flowering water jujube flowering often encounter high temperature and drought weather, it is easy to cause jujube head wilting off, should be sprayed on the jujube tree crown water, increase humidity, promote pollen germination. The water spray should be carried out before the high temperature arrives every day. Spray 3 to 4 liters of water per plant, spray once every 2 to 3 days, and spray 3 to 4 times.
Five, jujube head topping heart in the jujube tree flowering period, the new branch up to 30 cm long, will not update the dates of the jujube head to cut a part, leaving 3 to 4 secondary branches, to control the jujube head crazy, reduce nutrient consumption.
6. Spraying Boron Boron at Flowering Stage can promote pollen absorption of sugar, activate metabolic process, stimulate pollen germination and flowering pollen growth. Use 0.2% to 0.3% borax solution or 0.1% to 0.2% boric acid solution to uniformly spray the foliage.
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.
