不同施肥处理烤烟氮磷钾吸收分配规律研究
Studies on laws of N, P,K uptake and distribution of flue-cured tobacco with different fertilizer treatments
摘要
Abstract
Field experiment was carried out to study N, P, K uptake and distribution in flue-cured tobacco with three various fertilizer treatments. Results indicated that the amount of N,P,K absorption in flue-cured tobacco were 130. 64 kg/ hm2, 27. 35 kg/hm2 and 230. 03 kg/hm2 respectively with combined organic and inorganic fertilizers, while 40. 08 kg/ hm2, 10. 14 kg/hm2, 82.46 kg/hm2 respectively without fertilizer application, and 67.25 kg/hm2, 14.31 kg/hm2, 114. 7 kg/hm2 respectively with only organic fertilizer. The peak of N, P, K accumulation rate appeared 60-75d after flue-cured tobacco planting. The order of N, P, K distributed in root, stem and leaf was as follows: leaf > stem > root, and the amount of N, P, K accumulated in leaf was more than the sum amount in stem and root. To produce 100kg tobacco leaf, the required amount of N, P, K were 2. 63 kg, 0. 65 kg, 5. 31kg respectively without fertilizer, 3. 16 kg, 0. 67 kg, 5. 14kg respectively with only organic fertilizer, and 4. 26 kg, 0. 89 kg, 6. 65kg respectively with combined organic and inorganic fertilizers.关键词
