不同种类有机肥对油菜茬烟田供肥特性的影响

2007年,在河南省宝丰县油菜茬烟田进行不同种类有机肥的田间试验,研究了优质腐熟芝麻饼肥、腐殖酸、氨基酸3种有机肥对烟田土壤供肥特性的影响。结果表明:施用不同种类的有机肥可以不同程度地提高土壤中有机质、速效磷、速效钾含量,提高土壤供应N、P、K的能力,优化烟株生长环境。其中以腐殖酸和饼肥配施处理效果最好,其次是施用氨基酸有机肥处理。

The Effects of Different Kinds of Organic Fertilizers on the Soil Nutrition of Tobacco Field after Rapeseed Stubble

Field experiments had been conducted to study the effects of applying different organic fertilizers on the soil nutrition during development of flue-cured tobacco in 2007.Three different organic fertilizers,namely,manure cake fertilizer,humic acid fertilizer and amino acids has been tested in the present study.The result showed that applying different orgnic fertilizers could increase the contents of the organic matter in soil,hydrolysis of nitrogen,available phosphorus and available potassium in different degree.Then the treatments could increase the supply of N,P,K in soil,optimize the environment of tobacco growth.Among them,cake fertilizer and humic acid fertilizer showed the best effect,followed by the amino acids fertilizer.
