【摘要】 研究了水分对3个花生品种(鲁花11号、鲁花14号、花育16号)农艺性状及耗水特点的影响,在此基础上对各水分处理的经济效益进行了综合评价。结果表明:花生的荚果产量均随土壤相对含水量的上升呈先升后降的趋势,其中鲁花11号和花育16号在土壤相对含水量70%时荚果产量最大,而鲁花14号的荚果产量在土壤相对含水量60%最大。耗水量与水分生产率呈负相关,鲁花11号的抗旱性最强,鲁花14号次之,花育16号最差。就经济效益而言,鲁花14号在土壤相对含水量为60%时经济效益最佳,而鲁花11号和花育16号均在土壤含水量为70%时最佳,因此鲁花11号和花育16号的高产高效适宜土壤相对含水量为70%,而鲁花14号的为60%左右。更多还原

【Abstract】 The effect of different moisture treatments on the agronomic performance and water consumption characteristic of three groundnut varieties, including Luhua 11, Luhua 14 and Huayu16 were studied in this trial. We evaluated the economic value of each moisture treatment. The pod yield of groundnut increased at first and then decreased with an increase of the soil relative water content. The soil relative water content was 70% when the pod yield were the highest for Luhua 11 and Huayu16, While 60% for Luhua 14. The water consumption was negatively correlation with moisture production efficiency. The drought tolerance was the strongest for Luhua 11, the weakest for Huayu16 among these groundnut varieties in this experiment. The economic value was the best when the soil relative water content was 60% for Luhua14, while 70% for Luhua 11 and Huayu16. In conclusion, the optimum soil relative water content were 70% for Luhua 11 and Huayu16, and 60% for Luhua 14.更多还原
