基肥添加微生物菌剂和提苗肥对烤烟生长和养分积累的影响
Effects of Base Fertilizer Added Microbial Agent and Seedling-raising Fertilizer on Growth and Nutrient Accumulation of Flue-cured Tobacco
摘要
Abstract
To clarify the effect of adding microbial agents in base fertilizer and urea in seedling-raising fertilizer on promoting early growth and rapid development of paddy-tobacco,'Yunyan 87'was used as material,the two-factor experiment was designed by two application methods of base fertilizer with or without adding microbial agent,and three application methods of a single application of seedling-raising fertilizer for tobacco,a single application of urea,seedling-raising fertilizer for tobacco and urea mixed application.The effects of microbial agent,seedling-raising fertilizer and their interaction on root systems,agronomic traits,SPAD value,dry matter accumulation and nitrogen,phosphorus and potassium accumulation of flue-cured tobacco were studied.The results showed that the addition of microbial agent and seedling-raising fertilizer combined with urea was better than the single application of seedling-raising fertilizer and base fertilizer,root activity,root total length,surface area,average diameter,volume and root tip number were increased by 28.13%,5.41%,1.30%,17.23%,24.63%and 0.41%,respectively.Plant height,stem girth,number of leaves and maximum leaf area were increased by 10.06%,2.30%,18.75%and 37.26%,respectively.Total dry matter,nitrogen,phosphorus and potassium accumulation were increased by 27.18%,37.21%,36.57%and 23.97%,respectively.The addition of microbial agent and seedling-raising fertilizer combined with urea in the base fertilizer could improve the root activity of flue-cured tobacco,promote the root development of flue-cured tobacco,improve agronomic properties,facilitate the accumulation of flue-cured tobacco dry matter and nitrogen,phosphorus and potassium nutrients,promote the early growth and rapid development of flue-cured tobacco,and lay a foundation for the high quality and high yield of'Yunyan 87'in tobacco-rice rotation area.关键词
