沼液在农作物上的应用研究被引量:5
2012年
概述了沼液在农作物及烤烟抗病虫、浸种、改良土壤、增产增质以及无公害生产等方面的应用研究,并总结了近年来沼液在烤烟生产中的应用,以为沼液资源高效利用提供参考。

济源烟区土壤营养状况评价研究被引量:4
2010年
对济源市烤烟主产区植烟土壤的营养现状进行了分析,取样地点126个,覆盖了全市4个烟区(邵原、王屋、下冶和大峪)的植烟土壤。结果表明:济源烟区土壤总氮、碱解氮、有机质含量较适宜;个别地区速效磷、有效锌含量较低;水溶性氯含量均在合理范围;有效硼含量则明显不足;速效钾含量则比较丰富,在豫西乃至河南烟区都处于较高水平。

Soil Fertility Properties of Tobacco Growing Area in Jiyuan被引量:9
2010年
Soil fertility properties of the main tobacco growing area in Jiyuan (Shaoyuan,Wangwu,Xiaye and Daiyu) in west Henan Province were analyzed. Results showed that Jiyuan was one of the potential areas which could produce tobacco leaves with high quality. Its main properties of soli fertility were as follows:the content of total nitrogen,alkali-hydrolysable nitrogen,olsen-phosphorus and organic matters were suitable for high-quality tobacco production; especially,all the flue-cured tobacco growing areas in Henan Province were rich in available potassium; besides,the concentrate of water soluble chloride ion was at reasonable level. The problem was that the micro-elements such as Zn-DTPA and available boron content were at a low level in individual areas. Based on this survey,the recommendations for fertilization in Jiyuan such as stabilizing nitrogen rate,increasing phosphorus,stabilizing potassium,and applying boron commonly and supplementing zinc for the deficient soils were put forward.
