Analysis on Soil Nutrient Content Status and Distribution Features of Tobacco Planting Area in Luohe City
摘要
Abstract
Soil samples of 25 tobacco planting townships were selected and nutrient content status of tobacco planting area of Luohe City of Henan Province in 2013 was analyzed. The results showed that with increasing of depth of tobacco planting soil,soil pH value maintained basic stability,and overall performance of soil was slightly alkaline.However,soil organic matter content,available nitrogen content,available phosphorus content,available potassium content,total nitrogen content and ratio on carbon and nitrogen of soil(C/N)showed a decreasing trend with increasing depth of soil,their performances were 0~10 cm>10~20 cm>20~30 cm>30~40 cm>40~50 cm. Soil nutrient content of tobacco planting area in Luohe City varied from different soil layers. Organic matter content,available nitrogen content,available phosphorus,available potassium content,total nitrogen content in 0~10 cm depth of soil were significantly higher than 10cm below it(P<0.05),soil nutrient status of plow layer(0~20 cm)was significantly better than 20cm below soil,and the differences between them reached 0.05 level of significance. Average content of main soil nutrients,C/N ratio of soil and other indicators on farming soil in 0~20 cm depth have greater variation of tobacco planting area in Luohe City. Average content levels of soil nutrients in 0~20 cm depth were higher than soil nutrient levels in 0~50 cm depth,potential nutrient content level on soil of 0~50 cm depth was inadequate,especially C/N ratio of soil was low and not coordination.关键词
