摘要
通过不同比例的粉煤灰、磷矿粉和鸡粪混合施用,研究其对果园酸性土壤修复效应及苹果产量和品质的影响。试验共设4个处理,处理1:空白对照,处理2:粉煤灰3 150 kg/hm^2+磷矿粉3 150 kg/hm^2+鸡粪5 250 kg/hm^2,处理3:粉煤灰2 100 kg/hm^2+磷矿粉2 100 kg/hm^2+鸡粪10 500 kg/hm^2,处理4:粉煤灰1 050kg/hm^2+磷矿粉1 050 kg/hm^2+鸡粪15 750 kg/hm^2。结果表明,在果实成熟期,处理2、3、4土壤pH值分别比对照提高了30.57%、27.73%、24.88%;处理3土壤碱解氮、速效钾含量以及微生物总量显著高于其它处理,但土壤缓冲能力低于处理4,有效磷含量低于处理2;处理3果实产量最高,品质最优,但与处理4间无显著差异。综合分析认为,本试验条件下粉煤灰2 100 kg/hm^2+磷矿粉2 100 kg/hm^2+鸡粪10 500 kg/hm^2能有效地改良果园酸性土壤,促进果实增产提质。
Flyash,phosphate rock and chicken manure were mixed and then were applied into acidic soil in apple orchard to evaluate the effects on acidic soil restoration and yield and quality of apple. The study contained four treatments,i. e. treatment 1： control; treatment 2： 3 150 kg flyash ＋ 3 150 kg phosphate rock ＋5 250 kg chicken manure per hectare; treatment 3： 2 100 kg flyash ＋ 2 100 kg phosphate rock ＋ 10 500 kg chicken manure per hectare; treatment 4： 1 050 kg flyash ＋ 1 050 kg phosphate rock ＋ 15 750 kg chicken manure per hectare. The results showed that the soil pH value of treatment 2,3 and 4 increased by 30. 57%,27. 73% and 24. 88% respectively compared to control in the mature period of apple fruit. Under treatment 3,the available nitrogen and potassium contents and microorganism population in soil were the highest compared to the other treatments,but the soil buffering capacity and available phosphorus content were lower than that of treatment 4 and treatment 2,respectively. Although the fruit yield and fruit quality of treatment 3 were the best among the treatments,but no differences were seen between it and treatment 4. It is concluded that flyash,phosphate rock and chicken manure mixed at the level of 2 100,2 100 kg and 10 500 kg per hectare could obviously meliorate acidic soil in apple orchard,and therefore increased fruit yield and quality.
