研究了环割、树盘地膜覆盖及叶面喷施硼钙肥对桂味荔枝果实生长、落果裂果和果实品质的影响。结果表明:环割,覆盖地膜和硼钙肥处理均能显著促进果实横纵径增长和显著降低果实累积落果率,且均以硼钙肥处理表现最好;但3个处理均提高了采前日均落果数,以环割和覆盖地膜表现明显,环割和覆盖地膜处理还明显提高了裂果率,仅硼钙肥处理对裂果具有一定防控作用。此外,3个处理对单果质量和可食率影响不显著,但环割极显著降低了果实可溶性固形物含量。综合分析,在荔枝第一次生理落果后叶面喷施硼钙肥5次左右有利防控桂味荔枝落果和裂果,提高果实产量和品质。
The effects of ring mulching, mulching with tree trays and foliar boron-calcium fertilizers on fruit growth, fruit drop and fruit quality were studied. The results showed that ring mulching, plastic film mulching and boron and calcium fertilizers both promoted the vertical and longitudinal growth of fruit and decreased the cumulative fruit drop rate significantly, both of which were best treated by boron and calcium fertilizers. However, the three treatments increased the pre-harvest day The number of fruit dropped, the ring mulching and covering mulching showed obvious performance. The cut mulching and mulching mulching also significantly improved the fruit cracking rate, while the treatment with boron and calcium alone had some control effects on the fruit cracking. In addition, the effects of three treatments on fruit quality and edible rate were insignificant, but ring mowing significantly reduced fruit soluble solids content. Comprehensive analysis, in the first litchi physiological deciduous foliar application of boron and calcium fertilizer about 5 times the prevention and control of cinnamon litchi drop and crack fruit, improve fruit yield and quality.
