摘要
分析研究了施肥对汾阳地区晋龙1号、中林1号、礼品2号3个核桃品种产量的影响,并拟合回归方程找出核桃每公顷产值与肥料投入的关系;同时研究了不同采收时间对5个核桃品种(晋龙1号、晋龙2号、辽宁1号、中林1号、礼品2号)出仁率的影响。结果表明,施肥可促进核桃产量增加,增产效果与品种和树龄有关;树龄在20 a以内的晋龙1号、中林1号、礼品2号及实生核桃产值与肥料投入均可拟合成正比例关系;汾阳早熟品种晋龙1号、晋龙2号、辽宁1号及中林1号的最佳采收时间在9月8日前后,出仁率最高可达64.5%;晚熟品种礼品2号在9月15日为最佳采收时间,出仁率可达61.0%。
This paper mainly analyzed the effects of fertilization on the yields of walnut varieties of Jinlong 1, Zhonglin 1 and Lipin2 in Fenyang area, the relationship between output of walnut and fertilizer input, the effect of different harvest time on kernel percent of five walnut varieties(Jinlong 1, Jinlong 2, Liaoning 1, Zhonglin 1, Lipin 2). The results showed that fertilization could promote the increase of walnut yield, and the yield increasing effect was related to walnut varieties and tree age. The output value of walnut trees with the age less than 20 years was basically proportional to the fertilizer input. The best harvest time for early maturing varieties Jinlong 1,Jinlong 2, Liaoning 1 and Zhonglin 1 in Fenyang was around September 8th, and the highest kernel percent was 64.5%. But for late-maturing variety Lipin 2, the best harvest time was September 15 th, and the kernel percent could reach 61.0%.
