摘要
采用 3 年生桃品种仙岛 11 号为试材,通过设 0(清水对照)、200、350、500、650、800 g/株 6个施肥量梯度,观察测定不同施肥量桃树生长发育情况、果实品质变化、香气、经济效益情况,旨在选出最优施肥量,为生产上提供使用依据、减少资源浪费及土壤污染并节约成本.结果表明:施肥量 350 g/株处理桃树叶片气孔导度、叶面积与对照相比得到显著提升,分别增加了 21.74%、79.76%;单果重、横径、纵径与对照相比分别显著增加了 23.42%、7.43%、1.99%;可溶性固形物含量达 18.39%,经济效益也得到了明显提高.通过隶属函数法排名得出 350 g/株是最优施肥量.
Abstract
The three-year-old peach'Xiandao 11'was used as the test material,and six fertiliser gradients of 0(water control),200,350,500,650 and 800 g/plant were set up to observe and measure the growth and development of peach trees,changes in fruit quality,aroma,and economic benefits of different fertiliser applications,with the aim of selecting the optimal fertiliser application,providing a basis for the use of the production,reducing the wastage of resources and soil pollution,and saving the cost of fertiliser.The results showed that the stomatal conductance and leaf area of peach leaves were significantly increased by 21.74%and 79.76%,respectively,compared with the control;the weight of single fruit,transverse diameter and longitudinal diameter increased by 23.42%,7.43%and 1.99%,respectively,compared with the control;the content of soluble solids reached 18.39%,and the economic benefits were also significantly improved.The ranking by the affiliation function method concluded that 350 g/plant was the optimal fertiliser application amount.
