Skillful management after cherry blossom

Big cherry spring blossom and summer fruit. Recently, many cherry growers called to inquire about cherry post-blossom management technology. in this regard, the reporter visited Zhang Zhicheng, an expert on miscellaneous fruits at Northwest University of Agriculture and Forestry Science and Technology. Zhang Zhicheng reminded farmers that big cherries mature more than 30 days after blossom, and are now in a critical period of technical management from post-flowering to fruit ripening, and fruit growers must do a good job in the management of the following points. Fruit thinning: after physiological fruit drop, the fruits of small fruit, deformed fruit, injured fruit and too many slender branches should be removed to make the tree reasonable burden, balance the tree potential and improve the nutritional supply of fruit, which is beneficial to improve the fruit quality. Heart-picking: during the fruit expansion period, when the new shoot grows to about 20 cm, the new shoot is heavily heart-picked (pick the new shoot 1 big 2 or more). Controlling vegetative growth and regulating nutritional distribution can not only increase yield and single fruit weight, but also promote and improve the quality of flower bud development by thinning flowers and fruits and picking hearts. Picking leaves: Cherry leaves are hypertrophic, most of the fruits are easy to be covered, it is difficult to see the light, picking the right amount of leaves in the fruit coloring period is conducive to fruit coloring, but can not pick too many leaves, so as not to affect tree growth and flower bud quality next year. Brightening: laying silver reflective film under the crown during the fruit coloring period to increase the illumination of the lower part of the crown and the inner chamber, which is beneficial to the coloring of the fruit. Watering: after falling flowers, the fruit development is the size of soybeans, fruit development into the hard core period should be timely watering, to prevent "willow yellow fruit drop", watering requires a small number of times to avoid soil drought. After the fruit begins to color, try not to water or less water to prevent fruit cracking. Fertilization: during fruit development, foliar spraying calcium fertilizer and micro-fertilizer Yemianbao 800 times liquid, or Gaomeishi 400 times liquid, or Fengbao 200 times liquid, has a significant effect on increasing fruit number, solid content and chromaticity. Pest control: most of the diseases and insect pests of cherry fruits begin to harm during the fruit expansion period, so more attention should be paid to the pest control work in this period.
