荔枝从着果到果实采收要经历３～４个落果高峰，其中前２～３个高峰主要是由生理因素引起的，而最后一个采前落果高峰是由荔枝病虫害引起的。为此，我们研制出防止荔枝生理落果的保果剂，经生产上多年使用表明，能明显降低荔枝幼果期和中果期的生理落果，显著提高着果率。本试 Litchi from fruit to fruit harvest to go through 3 to 4 fruit drop peak, of which the first 2 to 3 peaks are mainly caused by physiological factors, and the last before harvest peak is caused by litchi pests and diseases. To this end, we have developed a protective fruit litchi berry fruit, after years of production that use, can significantly reduce the litchi fruit and deciduous fruit physiological decline, significantly improve the fruit rate.
