摘要
对龙廷杏梅树盘进行不同材料及不同组合方式的覆盖处理,结果表明:覆白膜的冠下反射率较大,各覆盖处理保水效果均好于对照,多重措施好于双层措施,双层措施又好于单一措施。地表覆膜使土壤温度明显上升,覆草处理土壤温度虽然上升慢,但保温效果好,土壤施入保水剂可以保持土壤水分,进行覆草和覆膜加保水剂的多重处理则可以扬长避短。各处理均可改善土壤区域环境的水热条件,提高杏梅的产量及品质。
The experiments of different materials were carried out on the Long-ting P.simonii Carr.orchard soil with diferrents cross patterns.The results showed that the reflectance of canopy with white veil were larger,the water conservation effects of all treatments were more significant than the contrast,multiple treatmengt were better than dual treatments,dual treatments were better than single treatments.Covered with veil treatments can improve soil temperature obviously;altough covered with grass treatments improve soil temperature slowly,they can contain it well;water retaining agent treatments had stronger soil moisture holding capacity;the multiple treatments can make best use of the advantages and bypass the disadvantages.All treatments improved water and temperature of soil and the illumination of the trees,so the yield and quality of Long-ting P.simonii Carr.had improved.
