Key techniques for promoting coloration of cherries in greenhouses
Spraying fruit-surface film-free bagging agent: spraying it on the fruit surface acts like bagging, does not affect fruit respiration, and can also prevent fruit russeting and fruit cracking, improve fruit-surface coloration and glossiness, reduce pesticide residues and improve quality. Foliar spraying of Xin Gao Zhi Mo (new high-fat film) can prevent leaves from viral infection, make branches and leaves lush and green, and enhance the accumulation and directional transport of photosynthesis products...

Leaf removal: on the basis of reasonable shaping and pruning and improving ventilation and light conditions within the canopy, during the fruit coloration period simply remove the leaves that shade the fruit from light. However, the degree of leaf removal should not be too severe, so as not to affect flower bud differentiation and development.
Laying reflective film: 10-15 days before fruit harvest, lay reflective film under the canopy to increase light reflection under the canopy and promote fruit coloring. If the late frost has already passed during the fruit coloration period, consider removing the top film to improve lighting and promote coloration.
