楚门文旦为柑桔属柚类柚种(Citrus grandis)的一个优良品种。着果率仅2～3％左右,且不稳定,严重地影响产量的进一步提高。1984～1985年我们进行不同生长调节剂提高文旦着果率试验。结果报道如下: 一、材料与方法 本试验连续两年均在玉环县解放塘农场海涂文旦园内进行。果园四周为高达9～11米的木麻黄防护林,砧木为当地的实生土栾。试验树为13年生。 1984年试验处理为: (一)2,4—D15ppm
Chimonanthus praecox is a good variety of Citrus grandis. Fruit rate is only about 2 to 3%, and is not stable, seriously affecting the further improvement of yield. 1984 ~ 1985, we conducted different growth regulators to improve the rate of Plum fruit test. The results are reported as follows: I. Materials and Methods The experiment was conducted for two years in succession in the seaflora pomelos of Jiefangtang Farm, Yuhuan County.
