土壤保育技术在洛宁烟区的发展现状

针对洛宁植烟土壤板结酸化,土壤C/N减小,容重增大,微生物活动能源降低,有效养分供应不足的现状,探明绿肥掩青,增施有机肥、农家肥(如牛粪等),豆浆灌根,秸秆覆盖等土壤保育技术对改善土壤理化性质、全面提升烟叶品质的重要性。结合洛宁烟叶生产实际,分析当前土壤保育技术开展中存在的问题,提出做好烟田土壤保育的有力措施,确保洛宁烟叶生产健康、持续、稳定发展。

The Development Situation of Soil Conservation Technology in Luoning Tobacco Planting Area

Aiming at the current situation of tobacco soil compaction and acidification,decrease of C/N ratio,increase of bulk density,reduction of microbial activity energy and inadequate supply of effective nutrient in Luoning,the importance of green-fertilizer covered,adding organic manure and farmyars manure (cow dung,etc.),irrigation with soybean milk,straw mulching and so on were ascertained.According to the actual production of tobacco leaves in Luoning,the problems in the development of soil conservation technology were analyzed,and powerful measures of soil conservation in tobacco fields were put forward to ensure the healthy,sustainable and stable development of Luoning tobacco.
