- 摘要:
- 研究不同水分条件对东北风沙土花生各生长期植株形态、生理指标、产量及水分利用率的影响。采用盆栽的方式对花生各生长期的土壤水分进行调控，对上述指标进行测定。结果表明，风沙土栽培花生苗期适当干旱对花生生长发育没有显著影响；花针期对水分要求明显增高，土壤含水量为田间持水量的60%为宜；结荚期必须提供充足的水分，否则严重影响荚果生长，导致减产。在各组处理中全生育期土壤含水量下限控制在田间持水量60%时，水分利用率最高，达到1.53 g/kg，产量92.9 g/盆也达到了较高的水平，该指标可用来指导东北风沙土花生补水灌溉。
- Abstract:
- We examined the effect of different irrigation water on peanut plant morphology, physiological index, yield and water use efficiency in the all growth period in the aeolian sandy soil of the northeast. The peanut was planted in pot, the irrigation was controlled in all growth period, and the above indicators were measured. The result showed that appropriate drought had little influence on growth of peanut at seeding stage; the demand of water increased obviously at the flowering stage, appropriate soil water content is 60% of field capacity; there must be enough water in the pod stage, or the pod wouldn’t grow well, leading to yield reduction. When soil water content is 60% of field capacity during the whole growth period in all the treatments, the water use efficiency is the highest, which was 1.53 g/kg, and the yield was 92.9 g/pot, and was higher than almost of the others. The index can be the guidance of peanut irrigation scheme in the aeolian sandy soil of the northeast.
