The specific measures involve doing a good job of the "five timely actions." 1. Remove cold-protection covers in good time. The strawberry is a temperate evergreen plant, and its root system begins to grow when the soil temperature is 1°C to 2°C. In practice, generally when the air temperature is around 5°C, it is time to...

To improve the fruit set rate of apricot blossoms, preparations must be made in advance and apricot blossom pollination must be done promptly, carefully and meticulously. For the main cultivars of apricot trees, choose varieties with natural pollination ability, a low rate of abortive flowers and a high natural pollination fruit set rate...

Its larvae feed on buds and tender leaves, and during outbreaks they also damage old leaves, the bark of tender stems, flowers and fruit. On damaged leaves, only the upper epidermis and veins remain. First-instar larvae of this pest are gregarious. From the second instar they begin to disperse and cause damage, and after the third instar their food consumption increases greatly. This pest is one of the most common and serious...

Autumn basal fertilization for sweet cherries is timely now, and fruit growers should not miss it
When it comes to the key points of autumn basal fertilization, the first thing to emphasize is "early." It is generally carried out in September-October, but early application in September gives the best results. This is because during this period the soil temperature is relatively high, the roots absorb fertilizer over a longer time, and the absorption rate is also fast. Once the fertilization timing is grasped, the application rate must also be increased...

Early fruit retention for lychee and longan: timely management to reduce fruit drop
Lychee downy blight mainly harms flower panicles and fruit, causing panicles to dry up, young fruit to drop, and ripe fruit to rot and deteriorate. After temperatures rise in early spring, it first infects flower panicles, then young fruit and ripe fruit. If the occurrence and infection of this disease cannot be controlled before flowering, then young fruit and ripe fruit will be damaged...
