不同有机肥对土壤及核桃果实品质的影响

为探究‘辽宁1号’核桃较适宜的有机肥种类及施肥方式，以‘辽宁1号’核桃树为试验材料，利用半焦肥、鸡粪及生物菌肥三种有机肥进行施肥处理，检测不同有机肥对土壤及核桃产量品质的影响。结果表明，生物菌肥施肥能显著提高果仁黄酮含量；鸡粪能显著提高果仁Fe、Zn含量以及土壤速效磷、速效钾含量；5.0 kg半焦肥能显著提高果仁多酚、土壤有机质含量；10.0 kg半焦肥施肥能显著提高核桃单果重、横径、脂肪含量，矿质元素中K、Ca、Mg、Cu的含量以及土壤全磷含量。综合比较，10.0 kg/株半焦肥施肥对核桃相关果实品质的影响较大；根据隶属函数分析得出10.0 kg/株半焦肥施肥是较优施肥方式。

Effects of Different Organic Fertilizers on Soil and Walnut Fruit Quality

In order to explore the suitable types and fertilization methods of organic fertilizers for ''Liaoning 1'' walnut, three types of organic fertilizers, including semi coke fertilizer, chicken manure, and biological bacterial fertilizer, were used for fertilization treatment on ''Liaoning 1'' walnut trees. The effects of different organic fertilizers on soil, walnut yield and quality were tested. The results showed that the application of biological bacterial fertilizer significantly increased the flavonoid content in fruit kernels, Chicken manure can significantly increase the content of Fe and Zn in fruit kernels, as well as the content of available phosphorus and potassium in soil, 5.0 kg semi coke fertilizer can significantly increase the content of kernel polyphenols and soil organic matter. Fertilization with 10.0 kg semi coke fertilizer can significantly increase the conterent of weight, lateral diameter, fat content, K, Ca, Mg, Cu, and soil total phosphorus in walnuts. Comprehensive comparison of above results showed that, the application of 10 kg/plant semi coke fertilizer has a significant impact on the walnu quality. According to the analysis of the membership function, the optimal fertilization method is to apply 10kg/plant semi coke fertilizer in walnut.
