Hand pollination in China has as much to do with economics and fruit biology as it does with bees 🙌 In the early 1990s, farmers of marginal lands in the Hindu Kush Himalayan region–an area spanning parts of Nepal, China, Pakistan, and India–realized that apples could be a major cash crop 😉 Tree fruits are ideal for this region because their land is mountainous and difficult to cultivate 🙌 Subsistence farming was replaced by fruit crop production. Farmers saw a significant increase in their incomes, with some regions doubling their earnings. They now have cash to pay their children to school or to build roads. Life quality has been improved. 
Insect-pollinated fruit trees can be found in open bowl shapes, making them easy for bumblebees to access. Because apples, like most fruits, need to be cross-pollinated, it’s important to have more than one variety in flower at the same time (known as pollination partners), so that bees can transfer pollen between them. Here are the four types of my flowers. Trees will ensure this happens and we will also have three very different flavored apples. These cross-pollinating apples can be used to make preserves. They are decorative, and they provide an autumn and early winter source of useful information. Winter food For birds. Modified by Michelle Kim, Kunshan (China) January 1, 2020 
The flowers of most varieties of apples are attractive to bees. Because they flower in springtime, there’s often very little competition for them from other flowers. They must be planted with a fertilizer as most varieties do not produce their own pollen. When choosing a pollinizer, it is important to get good advice. It must flower simultaneously and should not be closely related to trees that are being pollinated. It is best to place a polliniser on every row. This will allow bees to travel between the rows more easily. However, this is often excessive as it means that too many areas must be dedicated to pollinisers. The best compromise for pollination and pollinizers is to place the polliniser in the third tree of every row. The arrangement below allows for the pollinizer to be surrounded and tended by fruiting plants. Each fruiting plant is located next to a polliniser within the same row. For best pollination the pollinisers should be distributed so that they do not occupy the same row in each third row. This page was last edited on 93 Days ago by Siara from Puebla in Mexico. 
This is an impressive piece of art from treefruit.wsu.edu It shows how around one-third (or more) of all honeybee colonies are looking for nectar and pollen at any particular time. Rarely, foraging bees collect nectar as well as pollen in the same flight. Pollen-collecting honeybees make up about half of those who forage in Red Delicious apples. However, this number could increase with other types. About 80% of honeybees who forage in cherry orchards collect pollen. Orchardists favourr colonies that have a greater number of pollen collectors. This is because pollen collects fruit trees much more effectively than nectar collectors. With larger colonies large amounts Small colonies tend to have more pollen collectors, but a higher proportion of brood. Credit to Secret C., Abakaliki Nigeria for this illustration.
