摘要

为了提高陕北黄土丘陵沟壑区苹果幼树的栽植成活率和保存率

对3个穴状整地时期的土壤物理性状及苹果幼树生长状况进行了监测研究。结果表明

穴状整地后土壤容重降低

土壤总孔隙度和非毛管孔隙度提高。雨季前穴状整地提高了春季和幼树生长前期的土壤水分

减小了土壤日温差

提高了苗木成活率

促进了树体生长。但雨季后和春季穴状整地降低了春季和幼树生长前期的土壤水分

加大了土壤日温差

降低了苗木成活率

削弱了树体生长

并且加深了定植当年的地面塌陷深度

降低了苹果幼树冬春季的枝条含水量

提高了枝条抽条指数

降低了苗木保存率。陕北丘陵沟壑区栽植苹果时应该在雨季前穴状整地。

Abstract

In order to increase the livability and survival rate of young apple trees in the loess hilly and gully areas of Northern Shaanxi Province

soil physical properties and young apple tree growth were monitored by the three treatments of soil preparation by digging hole before rainy season

after rainy season

and in spring. Results showed that soil bulk density was decreased and soil total porosity and soil non-capillary porosity were increased after soil preparation by digging hole. For the treatment of soil preparation by digging hole before rainy season

soil moisture was increased in spring and tree growth prophase period ; soil temperature difference between daily max-temperature and daily min-temperature was decreased; tree livability was increased ; and tree growth was promoted. However

for the treatments of soil preparation by digging hole after rainy season and in spring

soil moisture was decreased ; soil temperature difference was increased ; tree livability was reduced ; tree growth was weakened ; ground subsidence depth was deepened in plant year ;branch water content was reduced in the winter and spring ; branch shriveling index was increased ; and tree survival rate was decreased. Soil preparation by digging hole before rainy season is suggested when apple trees were planted in the loess hilly and gully area of Northern Shaanxi Province.
