摘要
通过晚稻草腐熟还田后季种植烟草进行减量施肥试验，结果表明秸秆还田在测土配方施肥基层上减少氮10％、磷10％、钾10％～20％的施用量增产率仍可达3．4％。14％。同时容重均比基础土样下降，有机质明显提升，N、P、K营养含量也有所增加。
This study through the night after returning straw rotten, kinds of value of tobacco fertilization experiment, reducing the results showed that straw returned on soil testing formula fertilization at the grass-roots level to reduce 10% of nitrogen, phosphorus, potassium 10%-20% seems still can increase rate was 3.4%-14%. Bulk density were lower than foundation soil samples at the same time, the organic matter significantly promoted, N, P, K nutrient content also increased.
