水肥耦合对核桃光合特性及产量和品质的效应
Study on the effect of water-fertilizer coupling on photosynthetic properties yield quality of walnut
摘要
Abstract
[Objective]To explore the effects of different water and fertilizer treatments on the yield and quality of Wen185 walnuts,determine the optimal water and fertilizer regulation thresholds for the fruit tree and ascertain the optimal water and fertilizer combinations to improve walnut yield in the hope of providing some knowledge for understanding the coupling relationship of water and fertilizer in the trees in Xinjiang.[Methods]Wen 185 walnut was taken as the test species and different water and fertilizer and their interac-tion gradients were set to study their effects on walnut photosynthetic,yield and fruit quality.[Results]Under the same fertility condition,with the increase of irrigation quantity,walnut leaf Pn value,yield and fruit quali-ty indexes showed a increasing trend,and the difference was significant(P<0.05).Under the same irriga-tion amount,in low water,with the increase of fertilization,the walnut leaf Pn value and yield,the quality of fruit increased first and then decreased;in medium water and high water,with the increase of fertilization,the walnut leaf Pn value and yield,fruit quality showed an upward trend,but the difference was not significant(P>0.05).[Conclusion]The suitable watering amount was3.92 m3/plant and fertilizer application amount was 5.50 kg/plant in sandy soil of Wensu County,Aksu,Xinjing.Water and fertilizer have great influence on the yield and fruit quality of Wen 185 walnut,and water and fertilizer coupling treatments can improve the photosynthesis,yield and quality of the walnut.关键词
