为改善贵州铜仁植烟土壤理化性状,探讨不同复混有机肥与化肥配施对植烟土壤的pH、碱解氮、速效磷、速效钾和过氧化氢酶、蔗糖酶、脲酶、酸性磷酸酶的影响。结果表明:各配施复混有机肥处理较纯施化肥处理均能提高烤烟生育期的土壤pH、供肥能力和酶活性,而在3种供试的复混有机肥中,以(圈肥、油枯和秸秆)配合发酵的复混有机肥的效果较好。
In order to improve the soil physical and chemical properties of Tongren tobacco planting in Guizhou Province, the effects of different compound organic manures and chemical fertilizers on the pH, alkaline hydrolysis nitrogen, available phosphorus, available potassium and catalase, sucrase, urease, acid phosphatase Impact. The results showed that all treatments with compound organic fertilizer could improve soil pH, nutrient supply ability and enzyme activity during the growth period of flue-cured tobacco, compared with pure chemical fertilizer. However, in the three compound organic fertilizers, Oil dry and straw) with fermented compound organic fertilizer better.
