不同地布覆盖对桃园土壤及果实品质的影响

Effect of different ground cover on the soil and fruit quality of peach orchards

为研究不同类型地布对桃园土壤及果实品质的影响,2022年在婺城区白龙桥镇董村桃树种植基地开展可降解地布试验。试验品种为锦绣黄桃,以不覆盖地布为对照,设置双色地布、单色地布2个处理,采用田间调查、数据分析等方法,研究了不同地布对桃园土壤理化性质、果实品质以及土壤杂草生长状况的影响。结果表明,地布覆盖可以提高土壤含水量,覆盖双色地布的土壤湿度比未覆盖高21.5百分点;地布覆盖可以调节土壤温度,不同地布之间没有差异;地布覆盖后除了土壤碱解氮含量有提高,其余土壤养分没有影响;地布覆盖杂草抑制率100%,省工节本,单色地布成本更低,推广价值更高。

In order to study the effects of different types of ground cover on the soil and fruit quality of peach orchards,a degradable ground cover experiment was conducted in Dongcun Peach Tree Planting Base,Bailongqiao Town,Wucheng District in 2022.The experimental variety is Jinxiu Huangtao,with non covering ground cover as the control.Two treatments of dual color ground cover and single color ground cover were set up.Field investigations and data analysis were used to study the effects of different ground cover on the physicochemical properties of peach orchard soil,fruit quality,and soil weed growth.The results showed that covering with ground cover could increase soil moisture content,and the soil moisture content covered with dual color ground cover was 21.5 percentage points higher than that not covered;Covering with ground cover could regulate soil temperature,and there was no difference between different ground cover treatments;After covering with ground cover,except for an increase in soil alkaline nitrogen content,there was no effect on other soil nutrients;The weed suppression rate of covering with ground cover was 100%,which saved labor and costs.The cost of single color ground cover was lower,and the promotion value was higher.
