本文通过观察“五月红”落花落果规律,探讨了其落花落果的原因,并提出提高着果率的途径。观察表明,落蕾落花多于落果者,着果率极低。落果多于落蕾落花者,着果率明显提高;花量和花质与落花落果密切相关。植株营养状态为影响花量与花质的内因,大量抽发夏梢,是加剧生理落果的重要因素。改善植株营养状态和立地环境,能有效地提高着果率。 By observing the law of “May Red” falling and falling, this paper explores the reasons for its falling and falling, and puts forward the ways to improve fruit yield. Observations show that falling more than drop flowers falling off those who bear fruit rate is extremely low. Dropping more than falling buds, the fruit rate was significantly improved; flower and flower quality is closely related to the fall and fall. The vegetative state of plants is the internal factor that affects the flowering and flowering. A large number of summer shoots are extracted, which is an important factor to aggravate physiological declension. Improve plant nutrition status and site environment, can effectively improve the fruit rate.
