为提高温州蜜柑幼树的座果率和成果率,我们于1983年在昆明地区富民县大营公社的何光营、大营二队两个桔园进行叶面喷肥试验,获得了较好效果。现将初步试验简况综述如下。试验材料和方法两个桔园均以1979年定植的温州蜜柑(尾张)作叶面喷肥试验,共76株,分别用硼砂、磷酸二氢钾、复合肥以及其它微量元素混合或单独施用,共十种试验处理,并设对照。叶面喷肥按物候期于3月23日(抽稍、现蕾期),4月20日(谢花期、幼果出
In order to improve the fruitsetting rate and fruit-yielding rate of Young Satsuma saplings in Wenzhou, we carried out the foliar fertilizer experiments in 1983 at Heguanying Camp and Camp Second Team of Orange Camp, Fumin County, Kunming, obtaining better results effect. The preliminary test profile is summarized below. TEST MATERIALS AND METHODS Two orange orchards were sprayed with the leaves of Wenzhou Satsuma (Tail Sheet), planted in 1979, with a total of 76 strains. They were mixed with borax, potassium dihydrogen phosphate, compound fertilizer and other trace elements separately or separately , A total of ten kinds of test treatment, and set the control. Foliar fertilizer according to the phenophase on March 23 (pumping slightly, budding period), April 20 (thank the flowering, young fruit out
