本地早是黄岩主要柑桔栽培品种,在国内外享有盛名。由于以往对本地早品种特性和栽培技术缺乏深入研究,致使该品种有时表现投产迟、产量低,使发展造成困难。现对本地早栽培中的土宜问题进行了研究。 一、本地早在不同土壤环境条件下的生育状况 根据黄岩六种不同植桔土壤类型上生长的构头橙砧本地早观察,以涂性培泥砂土生育状况为好,不仅总生长量大,单位面积平 As early as the local Huangyan main citrus cultivars, renowned at home and abroad. Due to the lack of in-depth research on the characteristics and cultivation techniques of early native varieties in the past, the varieties sometimes show delays in production, low yields and make development difficult. We are now on the local culture of early cultivation should be studied. First, the local early in different soil environment conditions of fertility According to Huangyan six different types of cultivated orange soil growth on the first orange peel observed early to take advantage of the fertility status of reproductive sand, soil, not only the total growth of large, unit area level
