板栗关键生育期不同氮肥分配对土壤微量元素的影响
Impacts of Different Nitrogen Fertilizer Allocation on Soil Trace Elements during the Critical Growth Period of Chestnut
摘要
Abstract
The application of nitrogen fertilizer can influence the uptake of micronutrients by chestnut trees and induce alterations in soil micronutrient levels.This study investigated strategies to enhance chestnut tree assimilation of soil micronutrients through an analysis of nitrogen fertilizer allocation during key growth stages.It was found that there was generally an initial decrease followed by an increase in Mn,Cu,and Zn contents in soil.in Flowering perind,fruit enlargement periocl and fruit harvecest period.However,Fe content showed a continuous decline.Among all treatments tested,N7 treatment consistently exhibited lower levels of Mn,Cu,Fe and Zn contents in soil throughout each period,when the total application rate of nitrogen fertilizer was 750 kg/hm2.Therefore,applying a ratio of 2∶3∶5 for nitrogen fertilizer during the flowering period,fruit enlargement period and fruit harvest proved beneficial for promoting Mn,Cu,Fe and Zn absorption by chestnut trees.关键词
