A Complete Guide to Apple Bagging Time and Methods
Bagging Time Apart from apple varieties whose fruit surface is prone to russeting, early-ripening and mid-ripening apple varieties are usually bagged about 30 days after petal fall, while mid-late-ripening and late-ripening apple varieties are bagged 35 to 45 days after petal fall. If bagged too early, the apple surface will be more smooth and glossy at harvest, but because the young fruit's stalk is tender and slender, the fruit may drop with the bag in windy weather...

What are the methods for judging whether a watermelon is ripe?
1. Accumulated temperature method. Watermelons need a certain amount of accumulated temperature from flowering to ripening. Generally, early and mid-season varieties need 700--800°C from flowering to ripening, while late varieties need about 1000°C. Therefore, under conditions of timely sowing in spring and normal climate, the fruit development days of each variety are basically fixed. Early varieties need 28--3...

Detailed Explanation of Cherry Planting, Cultivation Techniques and Management Methods
I. Variety Selection, Orchard Establishment and Planting Chinese cherries have weak cold resistance and prefer a warm and moist climate, making them suitable for cultivation in areas with an annual average temperature of 15-16°C. Sweet cherries prefer cool and dry conditions. The natural dormancy period of cherries is about 80-100 days. The chilling requirement for sweet cherries to complete dormancy is 1100-1300 hours below 7.2°C. Sour...

Occurrence Patterns and Control Methods of Kiwifruit Gray Mold
Kiwifruit gray mold mainly occurs during the flowering stage, young fruit stage and storage period of kiwifruit. In severe years, the incidence rate in orchards and during storage can reach more than 50%. Kiwifruit gray mold has become one of the main diseases affecting the healthy development of the kiwifruit industry. 1. Symptoms When young fruit (late May to early June) is affected, residual stamens and petals are densely covered with gray spores. At the initial stage, the fuzz on young fruit turns brown, the skin is infected, and in severe cases it can cause fruit drop. Contaminated stamens and petals attach to leaves and form concentric ring lesions centered on them; the lesions expand and leaves drop. If rain occurs, the disease develops more severely. After fruit is affected, gray-brown mycelium and spores form on the surface, followed by black sclerotia. During storage, fruit is easily infected by diseased fruit.

Three Simple Methods to Protect Greenhouse Grapes from Freezing
In recent years, the area under protected grape cultivation has increased. Due to large temperature fluctuations in early spring, temperature inversion easily occurs inside the greenhouse, causing early-sprouting varieties to suffer freeze damage. The following measures can be taken in production for prevention and remediation. 1. Water 1 day before the cold snap arrives to increase soil moisture and air humidity inside the greenhouse, using moisture to regulate temperature. 2. In the vineyard...

Key Points and Methods of Banana Ripening Techniques Explained
1. Natural physiological after-ripening. This is the method by which bananas turn yellow and ripen by relying on the fruit's own after-ripening process, without artificially adding ripening agents. In seasons with higher temperatures (20°C-30°C), after the banana hands are separated, they are packed into fruit baskets, about 25 kg per basket, then placed in a sealed room and stacked 3-5 layers deep, and in about 7-10 days they turn yellow...
