摘要
针对宜昌市平原地区老果园树体弱、品质下降等问题,研究不同基肥对柑橘园土壤养分和果实品质的影响。结果表明,不同基肥处理对土壤肥力的提升作用不同,以沼气液作基肥对土壤肥力的提升效果最佳,可以增加土壤有机质和氮、钾的有效性;以腐熟的鸡粪和柑橘专用有机肥作基肥对土壤有效磷含量的提升效果更明显,但造成土壤速效钾含量的下降,因而以这两种肥作为基肥时应配合施用钾肥。虽然不同基肥处理可以显著影响土壤有效养分含量,但试验的第一年各处理对柑橘品质并没有显著的影响。因此,以有机肥作为基肥可以有效提高土壤肥力,但对蜜柑品质的影响还需要进一步研究。
In view of the depression in fruit tree and reduction in fruit quality of old orchards in plain areas of Yichang, the effects of different base fertilizer treatments on soil nutrient and citrus quality of citrus park were studied. The results showed that, different base fertilizer treatments were different in promoting the soil fertility, the treatment of biogas fermentative liquid have most effect to the increase of soil nutrient, which could increase the availability of the soil organic matter, nitrogen and potassium. Rotten chicken manure and citrus special organic fertilizer could apparently increase the available phosphorus but reduce the rapidly available potassium, thus it was better to add application of potassium fertilizer. Although different base fertilizer treatments could significantly affect the content of soil available nutrients, but the quality of citrus in the first year had no significant change. Therefore, organic fertilizer could obviously improve soil fertility, but the impact on the quality of citrus need further research.
