摘要
设置了不同施氮量及栽培密度对烟叶质量的影响试验。结果表明:在一定范围内,随施氮量增加,烟株长势越好;随种植密度的增加,烟叶产值、产量越高。以施纯N 6 kg/667m2,移栽密度为110 cm×56 cm处理的初烤烟叶产值、产量、外观质量等效果最佳。
K326, a tobacco variety, was tested to study effects of different nitrogen application amount and transplanting density on tobacco quality. The results showed that the plant growth vigour, output value and yield of tobacco leavies raised with increase of applying nitrogen amount and transplanting density in the test. The optimum output value, yield and exterior quality could be obtained under the cultivation condition of 7 kg/667m^2 of nitrogen application amount and 110 cm× 56 cm of transplanting density.
