The Selection Of Dense Planting Pear Varieties In Hebei Central South Area

While China ranks first in the world in pear cultivated area and output,Hebei Province ranks first in the country.Planting Density is the main cultivation method for newly developed pear trees.Variety is the essential factor that determines yield,quality and effectiveness of pears.Each variety has its own suitable region and range for cultivation,and each region has its suitable varieties.In order to choose pear varieties suitable for Planting Density in central and southern Hebei Province,13 pear varieties introduced into Handan,Hengshui and Xingtai were investigated in terms of biological characteristics,main economic traits and economic effectiveness.Through trial investigation and comparison,the suitable pear varieties were identified and their corresponding cultivation techniques were proposed,which is of great significance to the development of pear industry and the updating of pear varieties.The main findings are as follows:1.This paper presents the pear variety of suitable for close storage and density planting,which is the pear has strong Shoot Sprouting(the Shoot Sprouting rate of pear tree over fifty percent),freely branched,slow growth of new shoots,strong natural Spreading(the natural Spreading over sixty degree),easy formation of axillary flower bud(the fruit set rate over fifty percent),and good quality results.2.In terms of biological characteristics,the natural Spreading of Huangguan,Yuluxiang and Zaosuhong with low growth rate and the growth potential is strong;the Yuanhuang,Zaosuli,Aidang and Qiuyue with low Shoot Sprouting;Yali,Xinliqihao,Xizil,Xueqing and Hongxiangsu have stronger Shoot Sprouting rate,moderate growth,and the natural Spreading is also higher.The germination rate was over 88.7% and the branching ability was above 72.1%.3.In terms of the high yield,quality and storage stability of the variety,Xueqing and Xizil?,Huangguan and Hongxiangsu are more productive and of better quality;The content of soluble solids is more than 12.3%.4.According to the production cost and return on sales of the variety,Yuluxiang,Zaosuli,Xinliqihao,Qiuyue higher sale price,economic benefits are relatively good.According to the production cost and return on sales of the variety,through the analysis of biological characteristics,fruit traits and economic benefit,this paperpresents four varieties suitable for the cultivation of densely planted pears in Central-South Region of Hebei.The four varieties were 'Xinliqihao','Hongxiangsu','Yali','Xueqing'.According to different characteristics and habits,the corresponding cultivation techniques were put forward...
