摘要
本试验共设置3 个处理:CK(不间作)、处理1(间作玉米)、处理2(间作黄豆),研究了红枣间作黄豆在红枣生产上的应用效果.结果表明,处理 2 红枣的平均产量为29 375 kg/hm2,比CK增产13.5%,比处理1 增产11.3%;处理 2 红枣单果长且粗,糖酸比高,口感香甜;处理2 土壤中的全氮、全磷、全钾比CK分别高21.4%、23.0%、6.4%,比处理1 分别高65.9%、40.0%、11.2%;处理 2 土壤中的碱解氮、速效磷和速效钾分别比CK高14.0%、22.5%、17.9%,比处理1 分别高 7.9%,12.2%、13.8%;处理 2 土壤中有机质含量最高,比CK和处理1 分别高5.4%和5.0%;处理2 的红枣产量最佳,品质最优,土壤肥力最高,本研究可为当地其它林果间作经济作物提供参考.
Abstract
This study investigated the application effect of Red jujube intercropping with soybean on Red ju-jube production.Three treatments were set up:no intercropping(CK),intercropping with corn(Treatment 1),and intercropping with soybean(Treatment 2).The results showed that the average yield of Treatment 2 was 29,375 kg/hm2,which was 13.5%higher than CK and 11.3%higher than Treatment 1.The single fruit in Treat-ment 2 was longer and thicker,had a high sugar-acid ratio,and tasted sweet.The total nitrogen,total phos-phorus,and total potassium in Treatment 2 were 21.4%,23.0%,and 6.4%higher than CK,and 65.9%,40.0%,and 11.2%higher than Treatment 1,respectively.Soil alkali-hydrolytic nitrogen,available phos-phorus,and available potassium in Treatment 2 were 14.0%,22.5%,and 17.9%higher than CK,and 7.9%,12.2%,and 13.8%higher than Treatment 1,respectively.The content of organic matter in Treatment 2 was the highest,being 5.4%and 5.0%higher than CK and Treatment 1,respectively.Treatment 2 achieved the best yield,quality,and soil fertility.This study provides a reference for intercropping local cash crops with forest and fruit trees.
