红壤丘陵是江西柑桔生产的主要基地,对红壤丘陵低产桔园的改造是我省柑桔生产的一个重要课题。本研究旨在分析红壤丘陵低产桔园的土壤营养情况;找出影响产量的主要矛盾,为低耗、高效、改造低产园提供理论依据。 一、试验设计及方法 1、试验设计 1985年在宜春、信丰、吉安、南城及双金园艺场选择了典型的红壤丘陵高、低产桔园点。分别
The red soil hills are the main bases for the production of citrus in Jiangxi Province. The transformation of the low-yield orange groves in the red soil hills is an important subject of the citrus production in our province. The purpose of this study is to analyze the soil nutrient status of low-yield orange orchard in hilly red soil regions and identify the main contradictions that affect the yield, providing the theoretical basis for low-consumption, high-efficiency and transformation of low-yielding garden. First, the experimental design and methods 1, experimental design 1985 in Yichun, Xinfeng, Ji’an, Nancheng and Shuangjin horticultural market to choose a typical red soil hilly high, low yield orangery point. respectively
