不同调控技术对柠檬秋花果的调控效应
Effects of different regulating technologies on fruit of autumn flowering lemon
摘要
Abstract
Treatments spraying flower-promoting agent (Tl), spraying paclobutrazol (T2), spraying flower-promoting agent + stick twisting and band girdling (T3), spraying flower-promoting agent + 0.5 cm wide-band girdling (T4), spraying flower-promoting agent and potassium dihydrogen phosphate + 0.5 cm wide-band girdling (T5), spraying flower-promoting agent +deep-ditch uprooting and 0.5 cm wide-band girdling (T6) and CK spraying water were designed to study the effects of different regulating technologies on flowering and yields of eureka lemon. Mass fractions of flower-promoting agent, potassium dihydrogen phosphate and paclobutrazol used in the treatments were 0.66%, 0.3%, 0.1%, respectively. The results indicated that the number of flowers and flowering branches increased in all treatments. The number of flowers presented similar tendencies in treatments except Tl and T3 during the whole process of flower opening, which was low on July 29, the highest on August 13 and the lowest on December 15. The different treatments showed big influence on the amount of fruits from single plant, yield, production of bagged fruit, production of processed fruit, in which T6 showed the highest influence, followed by T6, T4, T5, T3, Tl, T2, CK (untreated). The yield and benefit of T6 was 215 thousand/hm2 and 139 thousand/ hm2, respectively, which was the highest and 2.8 times higher compared to CK, therefore the technology in T6 could be applied to lemon production.关键词
