How to prevent jujube fruit drop in summer and autumn? Please explain the methods
Summer and autumn are the critical periods for jujube fruit growth and development, and also the peak periods for the breeding and spread of various pests and diseases. In the high-temperature season, while jujube leaves release tree heat through transpiration, they can easily cause the fruit to crack. To prevent fruit cracking, the tree must be provided with a large amount of organic nutrients, sprayed with melon and fruit stem-strengthening agent to increase the nutrient supply needed for fruit development, and sprayed with 500-fold diluted Xin Gao Zhi Mo to protect against sun and water transpiration, so that the jujube fruit can expand normally and develop sugar and color.
Summer and autumn are the white-ripe stage of jujube fruit, and are the high-incidence stage of the pathogens of anthracnose, brown spot disease, and fruit shrinkage disease. In addition to timely spraying fungicides for early prevention, if jujube fruits suspected of being infected by pathogens are found, they should be promptly picked and buried deep, so as to prevent the pathogens from remaining to the next year and continuing to harm the jujube fruits.
This season is also the critical period for preventing fruit cracking. If no leaf-fall disease has occurred in the jujube orchard, regular irrigation should begin from the white-ripe stage, timely replenishing water for the jujube fruits, and increasing the water content in the jujube fruits in advance, so that the fruit cracking phenomenon can be effectively reduced during the rainy season.
