土壤是柑桔生育的基础.又是肥料、水分的储畜库与供应站.柑桔在水、肥、气、热协调的土壤环境中,根群发育良好,树冠生长旺盛,较快形成丰产稳产树形.从一九六六年到一九八二年原三明市种植的13万亩柑桔中,最高年总产623万斤,平均亩产1557.5斤,小面积最高亩产11800斤.最高株产525斤.但生产很不平衡,有的果区适龄不结果比例大,有的同年生的树,单产低,隔年结果明显,品质下降.这虽与海拔、生态有关,经一九八二年全市果园土壤普查发现,问题的症结在于土壤偏酸,有机质少、严重缺素、板结粘重等弊病,导致柑桔
Soil is the basis of citrus fertility and fertilizers, water storage stock and supply station.Crude orange root well developed in the soil environment coordinated by water, fertilizer, gas and heat, the canopy grows vigorously and forms the high yield quickly Among the 13 million mu of citrus grown in Sanming City from 1966 to 1982, the highest annual output was 6.23 million kg, with an average yield of 1557.5 kg per mu and a minimum mu yield of 11,800 kg. The highest strain of 525 kg, but the production is very uneven, and some fruit age-appropriate results do not result in a large proportion of some trees in the same year, low yield, obvious results every other year, the quality decline .Although this is related to altitude, ecology, In 1982 orchard soil census found that the crux of the problem lies in the soil partial acid, less organic matter, a serious shortage of nutrients, the sticky weight and other ills, resulting in citrus
