试验探讨了花期喷施植物生长调节剂 PCPA 对槜李、黄姑李着果能力的影响,结果表明:在落花末,单独喷30×10~(-6)PCPA 或混喷2000×10~(-6)硼砂加2000×10~(-6)磷酸二氢钾或混2000×10~(-6)硼砂明显提高了槜李、黄姑李的着果率,且能增加果实重量、提高果汁可溶性固形物含量.
The effects of spraying PCPA on the fruit yield and fruiting of Zizyphus jujuba and Huanggui plum during flowering were studied. The results showed that spraying 30 × 10 ~ (-6) PCPA or spraying 2000 × 10 ~ (- -6) borax plus 2000 × 10 -6 potassium dihydrogen phosphate or mixed 2000 × 10 -6 Borax significantly increased the fruit yield of P. purpurea and P. currantii, and also increased fruit weight and fruit juice Soluble solids content.
