The Occurrence and Prevention Control Techniques of Apple Orchard Continuous Cropping Disease in Yan'an Highland
Yan'an highland fruit area was a high-quality leading area for apple industry.At present,the problem of apple orchard recropping has become a limiting factor for the transformation and development of Yan'an apple industry.Since 2012,measures such as planting in the original tree pit,isolated planting in the original tree pit,planting in the central row of the original tree,soil replacement in the tree pit ditching for root clearing,storing and fertilizing,treatment and disinfection of seedlings dipping in the root with medicine and filling the root with microbial fertilizer have been adopted.To explore and study the technical measures to inhibit the continuous cropping disease.The results showed that the key to inhibiting the occurrence of continuous cropping disease was to plow deeply then improve the soil and the growth environment for new roots.Planting between the central rows of the original tree or isolating the original tree pit can obviously improve the microbial community structure of the new root soil,improve the soil effective nutrient return,and promote the vigorous growth of the plant.The author focused on the common problems restricting the development of apple industry,explained the causes of apple continuous cropping,combined with successful cases and put forward the new practical technology of apple orchard continuous cropping,aiming at providing technical reference for the upgrading of Yan'an apple industry and the enrichment of fruit farmers.
