1、经过土圵测试,当需要时施石灰。2、为取得优质高产,要为烟草提供充分的养料,但要避免过量或浪费。 3、大多数的施肥量应为:氮(N)9-11.3斤/亩;砖(P_2O_5)5.25-6.0斤/亩;钾(K_2O)15斤/亩。如果土圵发生淋溶,则需再增施氮钾肥。4、对这些养料最实用的施法是:以1:1:3的比例作移栽时的完全肥料施入,和仅用氮肥或氮钾肥作侧施追肥。 5、采用保证早期养分最大有效性和肥料损害最小的施肥方法。
1, after soil test, lime when needed. 2, in order to obtain high quality and high yield, to provide adequate nutrients for tobacco, but to avoid excessive or waste. 3, most of the amount of fertilizer should be: nitrogen (N) 9-11.3 kg / mu; brick (P_2O_5) 5.25-6.0 kg / acre; potassium (K_2O) 15 kg / acre. If soil 圵 leaching, you need to increase nitrogen and potassium fertilizer. 4, The most practical application of these nutrients is: 1: 1: 3 ratio of transplanting complete fertilizer application, and only nitrogen or nitrogen and potassium fertilizer for side application top dressing. 5, with the guarantee of the maximum effectiveness of early nutrients and fertilizer to minimize damage to fertilization methods.
