摘  要：
为了降低板栗空苞率和提高板栗果实品质,寻求合适的喷施生长调节剂的方法。以‘遵玉’为试材,于不同时期对板栗喷施不同的生长调节剂,探究生长调节剂对板栗结实情况和果实品质的影响。结果表明:盛花始期喷施SA可显著提高板栗实蓬率、每苞中板栗的个数和可溶性糖、淀粉和蛋白质含量,其中以0.2 nmol/L效果最佳,相比于对照组分别提高了15.50%、79.64%、19.20%、11.20%和6.09%;板栗幼胚发育前喷施0.01 mg/L BR可显著提高板栗实蓬率、可溶性糖和蛋白质含量,分别提高了14.16%、26.37%和5.69%,而喷施0.001 mg/L BR可显著提高板栗实蓬率和每苞中板栗的个数,分别提高了19.42%和125.56%,其中每苞坚果个数增幅高达125.56%,可显著提高板栗产量。因此,建议于板栗盛花始期喷施0.2 nmol/L SA,于幼胚发育前喷施0.001 mg/L BR或0.01 mg/L BR,以提高板栗产量和品质。

摘  要：
In order to reduce the empty shell ratio and improve nut quality of Chinese chestnut,to seek suitablegrowth regulator spraying method,with chestnut‘Zunyu'as test material,the author sprayed different growthregulators at different stages of chestnut,and explored the impact of growth regulators on fruiting conditionsand nut quality.The results showed that: at the beginning of full bloom,spraying SA could significantlyimprove the fruiting rate,the number of nuts in each bud,soluble sugars content,starch content and proteincontent of chestnut,which could be increased by 15.50%,79.64%,19.20%,11.20% and 6.09%,respectively,compared to that of the treatment CK,and the best spraying was 0.2 nmol/L.Spraying 0.01 mg/L BR before theperiod of immature embryo development could significantly increase the fruiting rate,soluble sugar content andprotein content,which could be increased by 14.16%,26.37% and 5.69%,respectively,and spraying 0.001 mg/LBR before the period of immature embryo development could significantly increase the fruiting rate and thenumber of nuts in each bud,which could be increased by 19.42% and 125.56%,and the number of nuts ineach bud could be increased up to 125.56%,significantly improve the yield of chestnut.Therefore,it isrecommended to spray 0.2 nmol/L SA at the beginning of full bloom and spray 0.001 mg/L BR or 0.01 mg/L BRbefore the period of immature embryo development,to improve the yield and quality of chestnut.
