摘要
[目的]比较不同有机肥及施肥深度对滨海盐碱地上银杏生长的影响.[方法]通过田间定位试验,比较不同施肥处理的土壤养分含量、电导率及根系生长情况,探明不同施肥处理对银杏生长状况和果实产量的影响.[结果]深施鸡粪有机肥处理的银杏≤2 mm根系的长度和体积分别为CK的2.7倍和1.8倍;冠幅、茎粗、单株产叶量、单株种核产量分别比CK高34.1%、25.9%、23.1%和37.8%.[结论]该研究可为同类地区银杏发展提供指导.
Abstract
[Objective]To compare the effects of different organic manure and depth of fertilization on the growth momentum of Ginkgo biloba L. in coastal saline-alkali land.[Method]By field-oriented experiment for seven consecutive years, explore the influence of the growth of Ginkgo bi-loba L.and the fruit yield by different fertilization treatments, by comparing the soil nutrient content, electrical conductivity and root growth of different fertilization treatments.[ Result] The results showed that the length and volume of ≤2 mm length root system in Ginkgo biloba L.which was treated by deep placement chicken manure were 2.7 times and 1.8 times higher than that of the control group, crown, stem diameter, leaf yield per plant, and plantlet yield were 34.1%, 25.9%, 23.1%and 37.8%respectively higher than the control group.[Conclusion]The study can provide guidance for the development of Ginkgo biloba L.in similar areas.
