摘要
为了探索减轻苹果幼树连作障碍的有效措施,增加耕地利用率,提高果园产量,于2009—2011年在牟平、招远(2处)、栖霞、蒙阴5处重茬果园定植苹果幼苗,结合苹果重茬综合防治技术体系进行管理。结果表明:活化发酵液处理重茬土壤地树体生长势明显增强,中枝数量、短枝数量、枝粗、株高、地径、新梢长、叶绿素含量平均分别增加105.45%、35.75%、35.92%、17.65%、23.66%、24.96%、9.16%。证明有机营养活化发酵液处理重茬土壤对苹果幼树克服连作障碍有明显改善作用。
In order to explore the ease of young apple of continuous cropping obstacles,increase the utilization rate of cultivated land and improve the orchard yield in 2009-2011,the author planted apple seedlings in Mouping,Zhaouuan（2 points）,Qixia and Mengyin 5 continuous cropping orchards,combined with comprehensive prevention and control technology system of apple continuous cropping.The result showed that：the trees growth potential of continuous cropping soil ground processed with active zymotic fluid was increased.In these orchards,the number of the middle branches,the short branches,the roughness of branches,the height and ground diameter of trees,the length of new tip and chlorophyll content increased by average 105.45%,35.75%,35.92%,17.65%,23.66%,24.96% and 9.16%.So it proved that active zymotic fluid processing continuous cropping soil could obviously reduce the continuous cropping obstacle on apple sapling.
