摘要
通过田间试验,揭示了花生的耗水规律、耗水量与产量的关系,初步得出花生耗水规律为苗期2.67～3.13 mm,花针期3.14～4.45 mm,结荚期4.39～5.37 mm,饱果期2.89～4.01mm。全生育期总耗水量502.73～650.13 mm。提出了在当地生产、气候和环境条件下花生的节水灌溉制度及适宜土壤水分控制下限。
According to the field experiment, the article revealed the law of water consumption and relationship between quantity of water consumption and production of peanut. The law of water consumption of peanut was obtained preliminarily based on the study results. It was： 2.67-3.13ram at seedling stage, 3.14-4.45mm at pod-pin stage, 4.39-5.37mm in pod bearing period, 2.89-4.01mm at plump stage. The water consumption was 502.73-650.13mm in the whole growth period. The water-saving irrigation system and low suitable soil moisture limit of peanut were proposed based on local production, climate and environment conditions.
