摘要
以西北农林科技大学校园内的健康成年毛梾单株为试材,通过对其进行为期2a的开花结实规律及物候期的观察,发现毛梾自然环境下坐果率仅为9.27%,产量低且不稳定。通过隔离花粉,激素和微量元素喷洒处理结果枝,环剥,疏花、疏果等措施,研究提高毛梾坐果率的最佳方法。结果表明:40mg/L 2,4-D处理结果枝对提高坐果率最显著,能提高产量112.94%,10mg/L赤霉素处理后提高产量70.33%,环剥+0.3%尿素+疏果提高产量60.84%。通过人工方法对结果枝进行处理,可以有效提高毛梾单株产量。
Using Comus wateri as experimental materials, through 2 years of phenophase observation, found that Cornus z^teri had a low yield,and the average was only 9. 27%. The research was to finding out the measures to increasing throughput by isolating pollen, ring stripped and thinning flower and fruit. The results showed that 40 mg/L 2,4-D could bring a high fruit-bearing rate,it was about 112, 94%. methods of gibberellic acid could bring a 70. 33% improving. It could has a high output of Comus wateri through manual handling work.
