向您提供几种使柑桔增产的新方法: 1.喷施硼肥在柑桔花期喷硼,有利受精结实,减少花蕾脱落,提高座果率。方法是在盛花期,用浓度为0.1—0.2％的硼砂水喷洒,最好选在晴天上午8—10时或下午4—6时,喷洒一次即可。据试验,用此法可使座果率达到7.98％,比喷清水的座果率3.7％提高一倍多。 2.用混合液处理此法是中国农科院柑桔研究所新近研究成的。将细胞激动素(BA)200—400PPM和赤霉素(GA)250PPM组成混合液,在柑桔谢花后7天左右处理单果一次。这样可有效地控制谢花后和幼果期的两次生理性落果,显著提高座果率,保持 To provide you with several new ways to increase the yield of citrus fruits: 1. Spraying boron fertilizer to spray boron on the flowering stage of citrus is favorable for fertilization and fruiting, reducing flower buds shedding and increasing fruit set rate. Method is full bloom, with a concentration of 0.1-0.2% borax spray, the best election sunny in the morning 8-10 o’clock or 4-6 o’clock, you can spray once. According to the test, with this method, the fruit set rate can reach 7.98%, which is more than doubled than the fruit set rate of 3.7% with water spray. 2. With the mixture of this method is the Chinese Academy of Agricultural Sciences citrus research recently into. The cytokinin (BA) 200-400PPM and gibberellic acid (GA) 250PPM composition of the mixture, Citrus Citrus spent about 7 days after the treatment of single fruit. This can effectively control two Xie physiological consequences after fruit and fruit stage, significantly improve fruit rate, maintain
