中文摘要: |
以常规红麻常规栽培种福红 992 为试材,设免耕(A)、垄耕(B)、深松耕(粉垄,C)3 种耕作方式与 T1(20%
作基肥,80%作追肥)、T2 (40%作基肥,60%作追肥)、T3 (60%作基肥,40%作追肥)3 种施氮方式共 9 个处理,分别为
AT1、AT2、AT3、BT1、BT2、BT3、CT1、CT2、CT3,探讨不同耕作和施氮方式对红麻产量和纤维品质的影响,为红麻高产高效
栽培提供合理的耕作和施肥依据。结果表明:(1)深松耕的耕作方式与 20%作基肥、80%作追肥的施氮方式互作时,红
麻的纤维产量和种子产量均达到最大值;(2)与免耕相比,深松耕的纤维产量、种子产量和纤维强力分别增加 17.0%、
14.8%和 18.4%,线密度降低 15.9%,深松耕可显著提高红麻产量和纤维品质;(3)与 T1相比,T2 的纤维产量、种子产
量和纤维强力分别增加 17.1%、30.8%和 17.6%,线密度降低 17.3%,适当增加氮基肥的比例可以增加红麻的产量和
纤维品质。 因此,采用深松耕结合 20%N 肥作基肥,福红 992 的纤维产量最高,同时兼收的种子质量也达到最大值。 |
英文摘要: |
The fiber yield and quality of regular cultivation kenaf (Hibiscus cannabinus L.), Fuhong 992, were
determined under three tillage methods (no tillage, ridge tillage and sub-soiling tillage), three nitrogen fertilizing methods
(T1: 20% N fertilizer as basal fertilizer; T2: 40% N fertilizer as basal fertilizer; T3: 60% N fertilizer as basal fertilizer). The effects of tillage and N fertilization methods on fiber yield and quality using a field experiment were studied to provide a
sensible solution for high yield and high efficient cultivation of kenaf. Results showed that, (1) the yield of fiber and seed
reached the maximum when 20% N fertilizer was as base fertilizer and 80% was as top dressing deep tillage farming
methods. (2) Compared with no tillage, the yield of fiber and seed, fiber strength increased by 17.0%, 14.8% and 18.4%,
while line density decreased by 15.9%. (3) Compared with T1, the yield of fiber and seeds, fiber strength of T2 increased by 17.1%, 30.8% and 17.6%, while line density decreased by 17.3%. Therefore, fibers yield of Fuhong 992 could get the
highest at deep tillage combined with 20%N fertilizer as basal fertilizer, and the yield of seed could reach the maximum,
too. |
