我县是柑桔新产区,从1978年开始陆续种植柑桔八十多万株。1982年开始使用广西省平乐县化工厂生产的三十烷醇,对5年生温州蜜柑进行保果壮果试验,使用浓度为0.13ppm,获得极显著的增产效果。座果率提高173.18％,试验单株产量17.89斤,对照7.56斤,增产136.64％。 1983年在100亩4～5年生温州蜜柑幼树上推广使用,浓度仍为0.13ppm,喷施时间为桔树初花期(5月上旬),生理落果初
My county is a new citrus producing area, starting from 1978, planting more than 800,000 citrus plants. In 1982, we began to use the triacontanol produced by the Pingle County Chemical Plant in Guangxi Province to test the 5-year-old Wenzhou mandarin fruit with the highest concentration of 0.13ppm. Fruit rate increased by 173.18%, the test yield of 17.89 kg per plant, control 7.56 kg, an increase of 136.64%. In 1983 in 100 acres 4 to 5 years to promote the application of young mandarin tree saplings, the concentration is still 0.13ppm, spraying time for early orange florescence (early May), physiology early fruiting
