行间生草对苹果园土壤养分与果实产量及品质的影响
Inter-row Grass Sowing on Soil Nutrients,Fruit Yield and Quality in Apple Orchards
摘要
Abstract
To investigate the effects of inter-row grass cultivation on soil nutrient characteristics and fruit quality in Linzhi orchard,Xizang,this study conducted single or mixed cropping experiments with multiple grass species in local apple orchards in 2021,aiming to assess the specific impacts of different grass cover treatments on soil nutrient content,fruit yield,and quality.The results showed that over two consecutive years of observation,the single sowing of white clover(T4)significantly increased soil alkaline nitrogen and total nitrogen content,with increases of 17.36%and 20.83%in 2022 and 15.17%and 41.98%in 2023 compared to the natural grass cover(CK).The mixed sowing of vetch and oat(T3)significantly enhanced soil available potassium content,with increases of 13.38%and 53.02%in 2022 and 2023 compared to CK.Additionally,the effects of grass cover treatments on soil available phosphorus and organic carbon content showed inconsistent significance over the two years,with a general downward trend observed for soil alkaline nitrogen,available phosphorus,available potassium,and organic carbon contents among the seven grass cover treatments in 2023 compared to 2022.In terms of fruit quality,grass cover treatments significantly increased individual tree yield and fruit weight of apples,with the white clover single sowing treatment(T4)achieving the highest individual tree yield,increasing by 54.69%and 26.65%in 2022 and 2023,respectively,compared to CK.While the significance of the impact of grass cover treatments on fruit shape and firmness was inconsistent over the two years,and there was no significant effect on vitamin C content,mixed sowing treatments(T3,T6)outperformed single sowing in increasing fruit soluble solids content and solid-acid ratio,effectively enhancing fruit flavor and quality.In conclusion,the single sowing of white clover as a grass cover treatment has the potential to further optimize the ecological and economic benefits in the apple cultivation area of Linzhi,Tibet.关键词
