南雄优质适产烤烟因土施肥技术研究

采用田间试验方法,探明南雄县烟区三种土壤类型氮、磷、钾养分的供应特性,烤烟在各生育期吸收养分的规律,不同土壤类型氮、磷、钾肥的不同配比对烤烟产量和质量的影响。根据三年试验结果进行统计,提出优质适产烤烟因土施肥技术方法,为南雄烤烟生产的发展提供了科学的施肥依据。

STUDY ON FERTILIZER PRACTICE FOR NANXIONG'S HIGH QUALITY AND MODERATE PRODUCTIVE ROASTED TOBACCO

By the experiments in field, the nutrient-supplying characteristics of N, P,K in three types of soils,the laws of nutrient uptake by tobacco at various growth stages, and the effects of different proportions of N, P, K fertilizers being applied to different soil types on yield and quality of tobacco, were explored in the tobacco production regions in Nanxiong county. The fertilizer practice for high quality and moderate productive roasted tobacco was made out from the statistical analysis on the three years of experimental results, providing a scientific basis of fertilizer application for the production of Nanxiong's roasted tobacco.
