摘要
通过田间试验,研究了滴灌灌溉制度对9年生成龄核桃产量及品质的影响规律。结果表明:①从对核桃产量影响分析的角度来看,土壤水分下限在果实膨大期对核桃产量影响最大,其次是硬核期,开花期影响最小。②从对核桃蛋白质含量影响分析的角度来看,土壤水分下限在开花期对核桃产量影响最大,其次是硬核期,果实膨大期影响最小。③从对核桃脂肪含量影响分析的角度来看,土壤水分下限在硬核期对核桃脂肪含量影响最大,其次是果实膨大期,开花期影响最小。
Through field experiment,we have studied the influence to the walnut yield and fruit quality of 9-year＇s walnut trees by drip irrigation schedule.The results showed that：1.soil moisture during fruit enlargement made the greatest impact on walnut yield,followed by the hard core of the flowering stage,and the least was the flowering stage;2.soil moisture in the flowering stage on the protein content of walnuts has greatest impact on walnut yield,followed by the hard core of the flowering stage,and the least was the fruit enlargement stage;3.soil moisture in the hard core of the walnut has the greatest impact on the walnut fat content,followed by the stage of fruit enlargement,flowering was the least.
