摘要: 为提高油桃砧木——毛桃播种苗的产量和质量,笔者开展了毛桃育苗及移栽试验,论述了宿迁地区毛桃的形态特征、生态习性等,研究了播种育苗密度及苗期田间管理等综合技术。结果表明,毛桃育苗及移栽密度以15株/m2为宜,当年生苗木平均地径可达0.9~1.0 cm;播种密度与苗木生物量呈负相关;苗木地径与株高、主根长、地下部鲜重及叶片数呈正相关,与地下部干重、Ⅰ级侧根长、Ⅰ级侧根数及Ⅰ级侧根位置无显著相关性。

Abstract: Abstract:In order to improve the yield and quality of peach seedings,The author has carried out the peach seedling and transplanting test,discussed the characteristics, ecological habits of peach of Suqian area, studied the comprehensive technology of seedling density and field management etc. The results showed that sowing and transplanting density to 15 strains per square meter was appropriate,the average diameter of seedlings reach 0.9-1.0cm in the same year;sowing density was negatively associated with seedling biomass;seedling ground diameter was positively related to the plant height, taproot length, lateral root length,root dry weight and number of leaves,There was no significant correlation between seedling ground diameter and root fresh weight,number and position of lateral root.
