摘要
本文针对四川秦巴山区春季气温低、湿度小的气候特点 ,采用 4种处理方法开展核桃嫁接增温保湿措施田间试验。结果表明 ,采用双层膜覆盖和拱膜覆盖措施 ,可以有效提高嫁接苗床的气温、地温和空气湿度 ,嫁接成活率较常规育苗方法分别提高 6 6 3%和 5 4 4 % ,并且嫁接苗长势旺 。
According to the low temperature and low moisture in spring in the Qingliang-Dabashan mountainous regions of Sichuan Province,four treatment methods were used for field experiments on the measures of temperature increase and moisture retention in walnut grafting.The results showed that the soil temperature,air temperature and air moisture could be effectively increased through covering by double-layer or arched plastic film,the grafting survival rate could be enhanced by 66.3% and 54.4% respectively compared with the conventional seedling production method,and the grafted seedlings grew vigorously.Therefore,these measures were worth applying in walnut grafting practice.
