为了探讨不同的播种期,不同的施肥水平和不同的覆盖物对大蒜产量的影响。我们进行了有关试验。供试材料“峨眉小梳牙”。播种期从“白露”开始,到“寒露”结束,共3期,分别是9月7日,9月22日和10月7日。施肥水平分别是亩施纯氮7.5公斤,10公斤和12.5公斤,覆盖物为稻草、盖土和不覆盖。用L_9(3~4)正交表安排实施。小区面积0.02亩,重复3次,随机区组排列。7×4寸开沟播种,每窝1株,每亩 In order to explore different sowing dates, different fertilization levels and different coverings on garlic yield. We conducted the test. Test materials “Emei small comb teeth.” Sowing period from the “white dew” to “cold dew” ended, a total of 3, respectively, September 7, September 22 and October 7. Fertilization levels were 7.5 kg Kushimizu nitrogen, 10 kg and 12.5 kg, covering the straw, covering the soil and not covered. L_9 (3 ~ 4) orthogonal table arranged to implement. Area of ​​0.02 acres of plots, repeated 3 times, random block arrangement. 7 × 4 inch sowing sowing, a nest, each mu
