金红苹果是我市主栽品种之一.1980～1981两年的试验表明,对金红苹果实行初花期喷硼能显著提高其座果率,尤其当花期遇到冻害等自然灾害时喷硼,效果更好. 1980年我们在江东公社大安果园,于初花期喷0.5%浓度的硼砂溶液,7月初调查,喷硼的花朵座果率为56.2%,最高达71.5%,对照(不喷硼)为27.8%,喷硼较对照的花 Gold-red apple is one of the main cultivars in our city.Experiment from 1980 to 1981 showed that the spraying of boron at the first flowering stage of golden red apple can significantly increase the fruit set rate, especially when natural disasters such as frost damage occur in flowering season In 1980, we sprayed 0.5% borax solution in the early flowering stage in Daan Orchard, a commune of Jiangdong commune. In early July, the fruitsetting rate of blown boron flower was 56.2% and the highest was 71.5% ) 27.8%, spraying boron compared with the control flowers
