由于茶树短穗扦插育苗是采用离开母体的茶树枝条的芽叶进行扦插培育茶园的,因此,扦插前苗圃地的畦面必须铺盖一层红、黄心土,其作用是防止插穗入土部分切口腐烂,促进插穗早日发根,减少畦面杂草。而所采心土及铺盖的质量又影响着扦插插穗的成活率和茶苗出圃率及苗木质量,故应加以重视。下面笔者谈谈心土的选取与铺盖技术。一、心土的选取1、所采心土必须是 pH 值为4.5—6.5的酸性红、黄心土(茶树是喜酸性土壤植物)。2、杜绝前作种过红茹、麻类
Because the short cuttings of tea tree seedlings are cuttings using the leaves of tea tree branches leaving the mother to cultivate the tea plantation, therefore, before cutting cuttage nursery grounds must be covered with a layer of red, yellow heart soil, its role is to prevent cuttings cuttings partial cuttings, and promote As early as the cuttings hair root, reduce face weed. However, the quality of heart soil and bedding affect the survival rate of cutting cuttings and nursery stock rate and seedling quality, it should be taken seriously. Here I talk about the selection of heart and bedding technology. First, the selection of heart and soil 1, the heart must be picked acid pH 4.5-6.5 acid red, yellow heart soil (tea is hi acid soil plant). 2, put an end to before planting red ru, bastard
