柑橘施用不同配比复混肥结果表明 ,与试验前同期相比 ,土壤中有效磷、有效钾、有效钙、有效镁、有效锌和柑橘叶片中的钙、镁、锌、铁的含量增加 ;而土壤中碱解氮和有效铁以及叶片中的氮、磷、钾的含量则降低。施用不同配比复混肥提高了柑橘多花和中花的比率 ,降低了少花的比率 ,增加了柑橘产量 ;同时改善了柑橘品质 ,提高了柑橘种植的经济效益。与常规施肥对照相比 ,柑橘产量增加 10 1～ 2 8 3kg/小区 ,增幅为 2 1 2 0 %～ 5 9 5 % ;经济效益增加 2 0 5 81 2 5～ 5 872 5 0 0元 hm2 ,增幅达 2 1 4 %～ 6 1 1%。喷施铁锌对柑橘的影响不大。
The results showed that the contents of available phosphorus, available potassium, available calcium, available magnesium, available zinc and citrus leaves in the soil were higher than those of the same period before the experiment. However, the contents of available nitrogen, available iron and nitrogen, phosphorus and potassium in the soil decreased. The application of compound fertilizers with different ratios increased the ratio of flowering and flowering of citrus, reduced the rate of flowering and increased the yield of citrus. At the same time, it improved the quality of citrus and increased the economic benefits of citrus cultivation. Compared with the conventional fertilization control, citrus yield increased by 10 1 ~ 2 8 3kg / plot, with an increase of 2120% ~ 595%; economic benefits increased by 285 ~ 5287200 yuan hm2, An increase of 2 1 4% ~ 6 1 1%. Spraying iron and zinc has little effect on the citrus.
