When planting cherry, what is the best measure to promote fruit swelling and coloring and improve surface light and fragrance? When the young fruit grows to the size of "jujube" 15-20 days after cherry blossoms wither, the fruit development will enter the hard core stage. In the hard-core stage of big cherry, although the fruit expands slowly or stagnates, if the nutrients and nutrients are not enough, the fruit will become "physiological fruit drop and the fruit will become smaller". Even if the fruit does not drop, it will cause poor gloss and color difference of the fruit. Therefore, strengthening the management of hard core stage is also the basis of improving quality and increasing efficiency at the stage of fruit color change and expansion.

In May, mature cherries cultivated in the open field, such as Aohong, Zaodaguo, Lv Guang and Meizao, were listed one after another, and middle and early maturing varieties, such as Rennie, Rabin and Samite, changed color and swelled. In 2022, the overall error of cherry fruit drop and winning by superior are the treasure places for many cherry friends and farmers to get rich. The countermeasures to promote fruit swelling and coloring and improve the taste of surface light are introduced as follows for reference only.

First, achene achene For weak trees with many fruits, we must make up our minds in advance. Immediately remove small fruit, abnormal fruit, damaged fruit, leafless or leafless fruit under the fruit, effectively load, reduce nutrient consumption, ensure nutrient supply of the fruit, and only need one piece of color, with good color and good taste.

2. The cherry fruit with excellent fruit, most of the pests are gradually damaged during the fruit expansion period. The key is to prevent germs and brown spot, apple leaf curl, stinkbug, pear moth, housefly and so on. To ensure smooth and rust-free fruit leaves. Control scheme: 400 kg water+12% zhongshengmycin 1 bag+echo 1 bottle+spectrum Yao 1 bottle+times or dazzling grains 1 bottle+calcium algae 1 bottle+silicon channel/

Multi-dimensional trace elements, such as silicon channels, algae high calcium milk, beneficial calcium, potassium dihydrogen phosphate, etc., are needed for cherry fruit coloring and swelling during the discoloration period. In particular, high-quality elements such as potassium, silicon, calcium and magnesium related to crack resistance of colored expanded fruits are filled immediately to promote fruit expansion, coloring and sweetening.

Third, the growth period of cherry with swollen fruit is short, and hard core fertilizer and color-changing fertilizer should be applied immediately after flowering 15-20 days. In the hard core stage of weak trees in high-yield period, "Hong Rui carbohydrate chelated Hefei 1 barrel+Australian Ruigen high-potassium water-soluble fertilizer 1 barrel" was applied, and in the color-changing stage of strong trees in high-yield period, "Kalahong 1 barrel+McCann high-potassium water-soluble fertilizer (4-10-50) was applied in 2 bags". After discoloration, in case of drought, it is often necessary to irrigate with small water to prevent fruit cracking.

4. Picking leaves and binding leaves before fruit ripening can significantly improve the irradiation regulations for purple fruit sales, and the leaves that cover the fruit can be moderately cut off. But the leaves on the fruiting branches play an important role in promoting flowers. Don't pick too many leaves. After picking the leaves, tie the remaining leaves together with a rubber band, so as to leave more leaves and raise them as high as possible. You can also spread reflective stickers to promote fruit coloring, and break up the leaves in time after picking the fruits.
