施肥对玉米茬烤烟农艺性状、产量和质量的影响

Effects of fertilizer application on yield and quality of tobacco in previous corn soil

玉米茬烤烟增施钾肥,显著提高烟草中上等烟比例和产值,但对产量作用不明显。增施磷肥,显著提高烤烟产量和产值;增施硼、锌,改善烟株农艺性状,显著提高烤烟中上等烟比例、产量和产值;增施钾、硼、锌,烟株生长健壮,中上等烟比例提高16.6%,产量提高23.4%,产值提高16.1%;增施磷、钾、硼、锌,烟株生长健壮,中上等烟比例提高20.6%,产量提高29.1%,产值提高31.0%。

More potassium fertilizer application in a previous corn soil can notably improve tobacco quali ty,in-crease out put value and yield.More phosphorus fertilizer application can significantly in crease yield and out put value,and improve tobacco quality.More Boron and Zinc fertilizer application can im prove tobacco agro nom ic characters and quality,and notably increase tobacco yield and out put value.Using more Boron and Zinc fertilizer or applying more phosphorus,Boron and Zinc fertilizer can miti gate the to bacco potassi-um starvation.
