An on-farm bamboo intercropping study was conducted near Solan, Himachal Pradesh, India. It uses a split-plot design with two bamboo species (Dendrocalamus asper and Dendrocalamus hamiltonii) and an open field condition as main plots, under which ginger (Zingiber officinale) was grown at five nutrient levels supplied through chemical fertilizers and organic sources (subplots). In the intercropping with bamboo species, ginger yield increased by 10.5–15.6% in comparison to the open field condition. Application of farmyard manure (FYM) based on N equivalent ratio showed the best (P ≤ .05) yield response of ginger (rhizome length, 7.65 cm; yield, 4,028 kg ha−1). Photoactive radiation was reduced by 60% under the bamboo canopy. Simultaneously, higher soil moisture (%) content was noticed for D. asper. Various soil physico-chemical properties (top 0–15 cm) were significantly higher in the FYM treatment under D. asper than under D. hamiltonii or sole ginger cropping. Maximum returns (3,595.67 US$ ha−1 yr−1) were realized when the ginger crop was raised under the canopy of D. asper and supplied with FYM on N equivalent ratio + plant growth–promoting rhizobacteria. Overall, the results establish that ginger production in the northwest Himalayan region of India is a viable use of land resources for improved economic returns.

以竹为基础的农林业系统对土壤肥力的影响:喜马拉雅山竹子冠层中的生姜性能(印度)

在印度喜马偕尔邦的索兰附近进行了农场竹间作研究。它采用裂地设计,以两种竹种(Dendrocalamus asperDendrocalamus hamiltonii)和开阔地条件作为主要地块,在该地块下,生姜(Zingiber officinale)以五种营养水平生长,通过化肥和有机来源(子地块)提供. 在与竹种间作中,与露地条件相比,生姜产量增加了 10.5-15.6%。基于N当量比施用农家肥(FYM)显示出姜(根茎长度,7.65 cm;产量,4,028 kg ha -1)的最佳产量响应(P ≤ .05))。在竹子树冠下,光活性辐射减少了 60%。同时,注意到D. asper 的土壤水分 (%) 含量较高。各种土壤理化性质(顶部 0-15 cm)在D. asper下的 FYM 处理中显着高于D. hamiltonii或单生姜种植下。当在D. asper的树冠下饲养生姜作物并以 N 当量比 + 促进植物生长的根际细菌提供 FYM时,实现了最大回报(3,595.67 美元 ha -1  yr -1)。总体而言,结果表明,印度喜马拉雅西北部地区的生姜生产是对土地资源的可行利用,以提高经济回报。
