夏季地面覆盖结合化学调控对温州蜜柑产量和品质的效应研究

Effects of Combining Ground Cover with Chemical Regulator on Fruit Yield and Fruit Quality of Satsuma in Summer

采用小区试验和示范性试验相结合的方法,研究了夏季地面覆盖(树盘覆盖稻草)结合化学调控(树冠喷施增果灵)对温州蜜柑产量和品质的效应。结果表明,7月中旬至8月底地面覆盖10～15cm厚稻草,结合喷施2次50μg/g增果灵,比对照增产15.0％～18.7％,且日灼果率降低4.0～3.4个百分点,单果重提高7.7～11. 4g,可溶性固形物、可食率、总糖分别高0.6、4.1及0.61个百分点。

The effects of Combining ground cover of rice straw sith spray of Zengguoling for satsuma in summer were studied by means of plot testing and large-scale demon stratinal esperment. The results showed that the fruit yield increased by 15. 0%-18. 7% ,and the rate of fruit sunstroke decreased by 4. 0-3. 4 percentage points, weight of per fruit increased by 7. 7-11. 4g,soluble solids content increased by 0. 6 percentage points, fruit eat proportion increased by 4. 1 percentage points,total sugar increased by 0. 61 percentage points under the condition of covering the ground with rice straw and spraying twice 50mg/kg zengguding from mid-July to August.
