继1986～1987年研制或A型肥和B型肥之后,1988年又根据湖南土壤,气候等条件,配制出6种复混肥(包括A型肥和B型肥),在24个植烟县(市)进行了肥效试验。结果表明,增施钾肥和施用稀土、硼、锌的综合效应能促进烟草生长发育,改善烟株农艺性状,显著或极显著地提高烤烟产量和质量.烤烟适宜施钾量为225～450kg/ha,平均为337.5 kg/ha;湘南、湘中烟区,施氮150～180kg/ha;湘西北烟区,施氮120～135kg/ha,能使烤烟达到优质适产的目标,1990年,选定氮:磷(P_2O_5):钾(K_2O)为10:12:24,加稀土、硼、锌和镁的配方生产出养分总含量达46%的“众望牌”烟草复混肥。

According to the soil, climate and other conditions, 6 sets of com-plex fertilizers for tobacco were complexed from 1987 to 1989. The expriments offertilizer efficiency have been conducted in 24 major planting places of tobacco.The result shows that the comprehensive functions of application potassium,boron, zinc and magnesium fertilizer can promote the growth and improve eachagronmical characters, especially waist-leaves and unilobed dry weight Andthe systems of nutrient fertilizing of some of major planting places of tobacco inHunan are laid down. Accoroding to the recipe of N:P:K (10:12:24)...
