- 摘要:
- 以‘甘科4号’辣椒为试材，以当地常规栽培作为对照（CK），采用温室大棚栽培的试验方法，研究椰糠、风沙土、人造泥炭、有机肥配比分别为5∶2∶1∶3（T1）、4∶3∶1∶3(T2)、3.5∶3.5∶1∶3(T3)、3∶4∶1∶3(T4)、2∶5∶1∶3(T5)、1∶6∶1∶3(T6)、0∶7∶1∶3(T7)复混形成的模块化生态保育基质对辣椒生长特性及产量的影响，以期为探索西部荒漠戈壁工业化土壤改良及特色生态农业发展提供新路径。结果表明：不同生育期下，T2~T5处理可促进辣椒长势（株高、茎粗、株幅），根系、品质和产量亦显著提高，且各项指标均随椰糠含量增加呈现先增大后降低的趋势；相较CK，T5处理下单株结果数和单株产量分别增加了9.47%、19.65%。利用VIKOR法对各处理的品质及产量进行综合评价显示，T5处理下辣椒品质及产量最优，利益比率最小，为0.019。研究结果进一步证明椰糠型生态保育基质（椰糠含量占比30%~55%)适合荒漠化土地上的辣椒种植。
- Abstract:
- Ganke No.4’ pepper was used as the experimental material，and the local conventional cultivation as the control group (CK).The greenhouse cultivation test method was used to study the coconut coir，aeolian sandy soil，artificial peat and organic fertilizer were mixed to form a modular ecological conservation substrate of 5∶2∶1∶3 (T1)，4∶3∶1∶3 (T2)，3.5∶3.5∶1∶3 (T3)，3∶4∶1∶3 (T4)，2∶5∶1∶3 (T5)，1∶6∶1∶3 (T6)，and 0∶7∶1∶3 (T7) on the growth characteristics and yield of chili peppers，in order to provide a new path for exploring the industrialized soil improvement and the development of characteristic ecological agriculture in the western gobi area.The results showed that under different growth stages，T2-T5 treatment could promote the plant height，stem diameter，plant width，with root system，quality and yield of pepper increasing significantly，either，and the quality and yield increased first and then decreased with the increase of coconut coir content.Compared with CK especially，the number of fruits and yield per plant increased by 9.47% and 19.68% respectively under T5 treatment.Additionally，the comprehensive evaluation of the quality and yield of each treatment by VIKOR method demonstrated that the quality and yield of pepper under T5 treatment was the best，with the smallest benefit ratio 0.019.Results further prove that coconut coir ecological conservation substrate (coconut coir content accounted for 30%-55%) was suitable for pepper cultivation on desert Gobi areas.
