祝光、红元帅、伏花皮苹果在西藏产量不高的主要原因之一是座果率较低。本试验主要探讨苹果盛花期在主枝上进行环状剥皮（简称环剥）和半环状剥皮（简称半环剥）处理，对上述三个苹果品种提高座果率的效果反应。试验表明，采用盛花期主技环剥和半环剥处理，可明显地提高祝光和红元帅苹果的座果率，而对伏花皮苹果则效果不显著。 Good luck, Red Marshal, Fu Hua Pi apple production in Tibet is not high, one of the main reasons is the low fruit rate. The main purpose of this experiment is to investigate the effect of ring peeling (semi-ring peeling) and semi-ring peeling on the main branch of apple at full flowering stage. Experiments show that the use of full-blown ring and half ring girdling technology, can significantly improve the fruit and red Marshmallow apple fruit rate, but the effect is not significant on the apple.
