Abstract: Abstract: effect of 27 years fertilization into soil on crops outputs of Cruciferae(cole) were studied in three typical parent material soil in south Hunan under long site experiment.The results showed follows: 1. Among the three types of parent material,the yield of rape( above-ground dry weight) was the best(NPK treatment was the best in purplish soil ), Quaternary red soil and in granitization red soil were followed respectively(both of the two types of parent material have weak growth vigor and have a consistent yield). 2.With plant rape,NPK treatment could get more harvest(biological yield) among the three types of parent material , M treatment and CK(no fertilization) were followed restectively. 3. The result also showed that return treatment is better than taken treatment within different treatments. 4. According to the experiment when the plant was harvested(In March 25th,2009), it was found that the rape with NPK treatment,especially with NPK-T treatment in Quaternary red soil and in granitization red soil, grew abnormality or dead in the centre of district(80%),which yield was extremely low,but had some to the remaining(20%) close to the cement ridge.Among the three types of parent material,eighteen districts,Dischaemum Schreb of gramineae plants could only grow in granitization red soil with NPK treatment,and the other sixteen districts were little or even not.The rape planted in Quaternary red soil with NPK treatment got disease especially in the centre of the district.The main symptom:there are some chocolate spot on leaf ,particularly severe on old basal leaves.
