摘要: 【目的】研究根施 N、P、K肥对平欧杂种榛坚果营养品质的影响,为生产中提高坚果营养品质提供科学依据。【方法】采用“3414”田间肥料效应试验,用多元线性逐步回归的方法分析施肥与坚果粗脂肪和粗蛋白含量的效应关系。【结果】在中等土壤养分条件下,平欧杂种榛的坚果粗脂肪含量(E)的反正弦(ArcsinE)同N肥施用量(纯N量)存在极显著(P<0.001)的正效应,同N肥与K肥的交互作用(N×K)存在极显著(P<0.001)的负效应。当P肥施用量(纯P2O5量)小于0.238 7 kg/株时,对坚果粗蛋白含量的常用对数存在正效应,反之则存在负效应,当施用K肥时,对坚果粗蛋白含量存在极显著(P<0.001)负效应,N肥与P肥的交互作用(N×P)则对坚果粗蛋白含量存在显著(P<0.05)正效应。【结论】在新疆特定的立地环境条件下,根施N、P肥可有效提高平欧杂种榛果实中的粗脂肪和粗蛋白的含量。

Abstract: 【Objective】 This Project aims to study the effects of root application of N P and K fertilizer on the nutritional quality of hazel nut in the hope of providing scientific basis for improving the nutritional quality of nut in the future production.【Method】 The effects of fertilization on nut crude fat and crude protein content was analyzed by using multi linear stepwise regression based on"3414" field fertilizer effect test.【Result】 Under the condition of medium soil nutrient, there was a significant positive effect between the crude fat content (E) ofCorylus heterophylla×Corylus avellana nut and the amount of N fertilizer (pure N) (P < 0.001), and the interaction between N fertilizer and K fertilizer had a significant negative effect of N × K (P < 0.001). When the fertilizing amount of P fertilizer (pure P2O5 amount) was less than 0.238,7 kg per tree,there was a positive effect on the common logarithm of crude protein content of nut, vise versa, there was a negative effect on the crude protein content of nut when applying K fertilizer (P< 0.001). The interaction between N fertilizer and P fertilizer (N × P) had a significant positive effect on crude protein content of nut (P< 0.05).【Conclusion】 Under the specific environment conditions of Xinjiang, root N fertilizer and P fertilizer can effectively improve the content of crude fat and crude protein in the fruit ofCorylus heterophylla×Corylus avellana.

Key words: Corylus heterophylla×Corylus avellana; crude fat content; crude protein content; nitrogen fertilizer; phosphorus fertilizer; potassium fertilizer
