May cherry quality guarantee has a coup
Cherry fruit has a short development period and matures early. From spring flowering to fruit ripening, it takes only 30 to 60 days for normal or late-maturing varieties. During this period, as the main producing area of ​​cherries, the north is often dry and drier, often causing small fruit, dry yellow fruit and so on. Water regulation. In view of the lack of water in the fruit expansion period, the fruit is small, and the lack of water in the young fruit stage is prone to dryness and falling fruit. The regularity of cherries watering throughout the year is from the second year of cherry planting, in normal years, generally 6 to 7 times per year, before germination, after Xiehua, and during rapid expansion of fruit (2 times), September to October. During the dry period, before the soil is frozen. Increase the fruit set rate. The first is to increase the storage nutrients of the tree, mainly to increase the nitrogen nutrition and photosynthesis products of the tree, and provide sufficient nutrition for the germination, flowering, fruit setting and new shoots of the coming year. In mid-October, the leaf surface was sprayed with biological amino acid 300 times twice, with an interval of 10 days; before spraying, the biological amino acid was sprayed 100 times once. After harvesting the fruit, spray 4~5 times of fungicide to prevent leaf spot and prevent early leaves. Followed by seaweed fertilizer, seaweed extract such as seaweed extract in the cherry bud stage and the end of the Xiehua period can effectively increase the leaf area and fruit transverse diameter. The third is to put the bees in the orchard. Three days before flowering, the orchard releases 300 to 500 head bees, or the first flowering period releases two bees per acre. Control production. For the production of high quality cherries, the output should be controlled at 750 kg per mu. Watering after flowering will affect fruit setting sooner or later. The test proves that watering on the first day after Xiehua can keep about 80% of the original fruit amount of the tree when the flower is given, and the fruit setting is reduced by 10%~15% every time the watering is delayed for one day. Therefore, in the production should be based on the target output, choose the post-flowering watering time to adjust the tree fruit set. In view of the law that the weak tree sits on the fruit and the tree is less, the robust tree can be cultivated by adding other agronomic measures such as nitrogen fertilizer. Increase the fruit. Mainly using CNK synergistic fruit-expanding technology, in the rapid expansion period of the fruit after the cherry hard core, combined with watering, apply 30 kg of ammonium bicarbonate and 10 kg of potassium nitrate per acre, and apply twice. Not only is it big, but it is bright and bright. At the same time, cultivating high-quality arborescens is a fruitful and fruitful basic measure, mainly to maintain the moderateness of the tree and open the tree; to cultivate the buds full, the branches are full and slow by lychee, twisting branches and pulling branches. The growing developmental branches lay the foundation for the development of high-quality leafy branches of these developmental branches in the coming year.
