霍山县山区猕猴桃栽培管理技术OA

Based on the ecological conditions of the mountainous area in Huoshan County,Anhui Province,the cultivation and management technology of kiwifruit from 3 aspects:pre-preparation,planting and cultivation,and field management was summarized.Based on the ecological adaptation characteristics of mountainous areas,scientifically select the cultivation varieties of kiwifruit,establish the main cultivated variety as Pingyuanhong,and combine with Wanhuang and Xuxiang varieties.The planting ratio should be controlled at 8∶1∶1;the seedlings are preferably selected as one-year-old grafted seedlings with vigorous growth.Planting is mainly in spring,and planting holes are dug with a specification of 80 cm×80 cm×80 cm.Strictly follow the principle of planting shallowly,ensuring that the grafting interface is 5 cm above the ground;in the first year of planting,1.8 m high branches or bamboo poles are inserted around the root area of the seedlings as supports.The irrigation method should primarily adopt drip irrigation or micro-sprinkler irrigation;the shaping and pruning should focus on cultivating a standard tree shape of"one main trunk,two main branches and six lateral branches"as the core objective,and standardize the layout of branches;fertilization should follow the principle of"organic fertilizer as the main,trace element fertilizers as the supplement,combining base fertilizer and topdressing",and implement differentiated fertilization according to tree age and phenological period to meet the nutrient requirements of different growth stages.At the same time,timely carry out flower and fruit management such as pinching,bud removal,pollination and fruit thinning to improve fruit quality and yield;disease and pest control adheres to the concept of"prevention first,comprehensive control",and prioritizes the use of physical control and biological control measures,proper application of chemical agents,focusing on controlling common diseases and pests of kiwifruit such as canker and soft rot.This article provides technical references for local kiwifruit cultivation practices.
