温州蜜柑适宜于北缘地区栽培。但要实现速生丰产是值得进一步研究的,笔者就多年实践体会,谈些看法,供北缘桔区参考。一、关于栽植密度及其效应北缘地区栽培柑桔,都基本上存在20年和10年一遇的周期性大、小冻害。基于这一客观实际,从栽培角度加密单位面积的种植密度,充分利用空间和改善、调节桔园小气候是很 Satsuma Wenzhou suitable for cultivation in the northern margin. However, to achieve fast-growing and high yield is worth further study, the author of many years of practical experience, talk about some views for reference to the northern margin of the Orange Region. First, on the planting density and its effects Cultivation of citrus in the northern margin of the region, there are basically 20 years and 10 years once the cycle of large and small frost damage. Based on this objective reality, it is very important to encrypt the planting density per unit area, make full use of space and improve and adjust the microclimate of the orange orchards
