不同间作措施对高原苹果行间土壤和果品质量的影响
Effects of Different Intercropping Measures on Soil and Fruit Quality of Apple Rows in Plateau
摘要
Abstract
[Objective]The effects of intercropping measures on soil and fruit quality of apple row were studied by using Vicia sativa(IL),Vigna umbellata(IG)and potato(IP)as intercropping crops combined with soil cover of pine needles(PC).[Method]The effects of inter-cropping measures on soil nutrients,heavy metal contents,C/N,soil aggregates,fruit quality and safety of orchard were investigated through field trials of intercropping of PC,IG,IL,IP and conventional management(CK).[Result]Using intercropping crops such as IL,IG,and IP could increase soil organic matter(with the highest increase in IL up to 30.7%),alkaline nitrogen(with an increase of 71%),available phosphorus,and available potassium,while reduced soil heavy metal content(by 5.4%to 25%),the proportion of soil aggregates＜2 mm increased by 20%or more.Intercropping could increase soil organic carbon and nitrogen reserves(40%),but the C/N ratio showed a decrea-sing trend.The contents of heavy metals(As,Pb and Cd)in soil under different intercropping treatments increased and decreased,but the differences were not significant.In the early stage of soil covering,PC showed good effects on soil moisture preservation and weed control,the VC content of apples increased significantly,which was the highest among all treatments(456.28 mg/kg).Sowing Vicia sativa could increase the ratio of sugar to acid of apple(2.3%),soluble solids and VC content(5.6%and 6.5%respectively),improve the nutritional quality of fruit,and ensure the yield of apple.[Conclusion]According to the practical management technology of orchard production,it is recommended to adopt the intercropping model of pine needle mulching in dry period and sowing of green fertilizer such as Vicia sativa in rain period.关键词
