以13～14年生田中枇杷为材料,研究疏花疏果与套袋对枇杷果实生长及品质的影响,结果表明,疏花后可有效减少养分消耗,使座果率提高10.2%;枇杷疏果以每穗留3～5个果为宜,疏果后可使平均单果重和商品果率分别比对照提高13.4g和27.3%,锈斑果率、日灼果率和裂果率分别比对照降低12.4%,0.6%和9.7%;疏果后套袋可完全避免日灼的发生,锈斑果率由35.2%降低到0.9%,商品果率从57.8%提高到96.3%;同时可提高枇杷果实的可食率、可溶性固形物含量、总糖含量和糖酸比,有效改善果实品质、口感风味、色泽和贮藏性能。
Taking 13 ~ 14 years old Tanaka loquat as material, the effects of thinning and thinning bagging on the growth and quality of loquat fruit were studied. The results showed that after the thinning flower, the nutrient consumption could be effectively reduced and the fruit set rate increased by 10.2% The results showed that the average fruit weight and fruit yield were increased by 13.4g and 27.3% respectively compared with the control after the fruit thinning, the rust spot rate, sunburst rate and split fruit rate decreased by 12.4 %, 0.6% and 9.7%, respectively. After thinning, bagging can completely avoid the occurrence of sunburn, the rust percentage decreases from 35.2% to 0.9%, the commodity fruit percentage increases from 57.8% to 96.3%, and the loquat fruit can be increased Feed rate, soluble solids content, total sugar content and sugar to acid ratio, effectively improve the fruit quality, taste, color and storage properties.
