摘要
笔者以香蕉(Musa nana Lour.)为材料,进行沼液配方肥的肥效试验并研究沼液配方肥对香蕉产量、果实品质和试验地土壤性质的影响。结果表明:施用沼液配方肥可以提高香蕉产量、果实品质,改善海南砖红壤,提高酸性土壤p H、增加土壤养分含量。与施用常规化肥相比,施用沼液配方肥的香蕉果指长增长5.59%、果指围增粗11.01%、每梳个数增加3.21%、单株产量提高了4.09%,香蕉果实蛋白质增加10.67%、可溶性含糖量6.66%、维生素C增加3.32%,不同土层土壤有机质增加2.98%~3.93%、碱解氮增加2.25%~17.07%、有效磷增加5.59%~18.64%、速效钾增加25.20%~39.20%。对香蕉施用沼液配方肥不仅提高作物其产量和果实品质,而且可改善种植地土壤的状况。试验结果可为沼液配方肥深度研发、推广及其海南土壤性质改良提供依据。
Biogas slurry was used to prepare a formulated manure to apply to the banana to determine its effect on yield,fruit quality and soil properties of banana in Hainan. The results showed that the biogas slurry formulated manure improved the yield and fruit quality of banana,the laterite soil,the p H of acid soil,and the soil nutrient content. Compared with the conventional fertilizers,this formulated manure increased the fruit length by 5. 59%,the finger girth by 11. 01%,the number of hands by 3. 21%,the yield per plant by 4. 09%,the protein content of banana fruit by 10. 67%,the soluble sugar content by 6. 66%,the vitamin C by 3. 32%,the soil organic matter content by 2. 98%-3. 93%,the alkaline hydrolizable nitrogen content by 2. 25%-17. 07%,the available phosphorus by 5. 59%-18. 64%,and the available potassium by 25. 20%-39. 20%. The formulated manure improved not only the crop yield and fruit quality,but also the soil regime of the banana plantation. This study provides reference for further development and promotion of biogas slurry manure and its use in improving soil properties in Hainan.
