过量灌溉条件下起垄栽培对富士苹果生长和15N-尿素利用、分配的影响
Effects of ridging cultivation on the growth of Fuji apple trees and the utilization and distribution of 15N-urea under excessive irrigation
摘要
Abstract
Experiments were designed to explore the effects of ridging cultivation on apple tree growth,utilization and distribution of 15 N-urea under excessive irrigation on 4-year-old apple trees (Fuji/SH40/ Malus robusta Rehd).Compared to the flat cultivation under excessive irrigation,the ridging cultivation could increase the activities of SOD and POD to 1.70 times and 1.69 times,decrease the free proline content to 63.60％,and increase the root activity and the fine root growth to 1.44 times and 1.68 times at the spring shoots growth arrest stage.These changes are also found in same pattern at the autumn shoot growth arrest stage.At the spring shoots growth arrest stage,the nitrogen use efficiencies (NUE) with ridge cultivation and flat cultivation are 4.40％ and 3.86％,no significant difference existed between the two cultivation ways.The NUEs are 5.16％ and 4.02％ respectively,but no significant difference.The15N distribution rates in the vegetative organs are higher with ridging cultivation than with flat cultivation,the biggest difference occured in the fine roots,and the differences became increased with the process of the growth.关键词
