    摘要:

    以亚麻荠新品种延世一号为试材,通过调查其不同温度(5、10、15、20、25 ℃)下的发芽率,不同播种期(春播、秋播)下的生育期,测定不同株行距(30 cm×10 cm、30 cm×20 cm、45 cm×10 cm、45 cm×20 cm、60 cm×10 cm、60 cm×20 cm)和不同穴密度(2、4、6株/穴)下的产量,不同施肥水平(不施肥、低肥(50 kg/hm2尿素+30 kg/hm2磷酸二铵)、高肥(80 kg/hm2尿素+50 kg/hm2 磷酸二铵))下的产量以及品质(出油率、粗蛋白、粗脂肪、脂肪酸含量)等,对其进行了生物学特性及高产栽培技术的研究。结果表明:延世一号种子在5~25 ℃均可发芽,当恒温25 ℃时,发芽只需3 d,发芽率达90%;春播的生育期为86~98 d,秋播的生育期为209~244 d;延世一号在龙井市春播的最高产量为194.30 g/m2,在东营市秋播的最高产量为223.50 g/m2;不同株行距的试验结果表明,60 cm×20 cm 的产量最低(148.10 g/m2),显著低于其他各处理,30 cm×10 cm的产量最高(182.10 g/m2);不同穴密度的试验结果表明,6株/穴的产量最低(137.10 g/m2),2株/穴的产量最高(187.60 g/m2);不同施肥水平的试验结果显示,在低肥处理下延世一号的产量最高(199.60 g/m2);品质分析结果表明,延世一号粗脂肪含量、粗蛋白含量和出油率分别高达37.80%、27.40%和36.22%,主要不饱和脂肪酸亚麻酸、亚油酸、油酸含量分别为13.05%、21.8%和21.65%。

    Abstract:

    This test was used the new variety of Camelina sativa (L.) Crantz of Yanshi–1 as test materials, its biological characteristics and high yield cultivation techniques were evaluated through investigating the germination rate under the different temperature (5, 10, 15, 20 and 25 ℃), the growth period and yield under the different sowing time (spring sowing and autumn sowing), measuring the yield under the different row spacing (30 cm×10 cm, 30 cm×20 cm, 45 cm×10 cm, 45 cm×20 cm, 60 cm×10 cm and 60 cm×20 cm) and different hole density (2, 4 and 6 plants each cave) and different fertilizer levels (no fertilizer, lower fertilizer (CO(NH2)2, 50 kg/hm2, (NH4)2HPO4, 30 kg/hm2) and higher fertilizer (CO(NH2)2, 80 kg/hm2, (NH4)2HPO4, 50 kg/hm2)), analyzing the quality characteristics (oil yield, crude protein, crude fat and fatty acids contents) and so on. The results showed that the variety of Yanshi–1 seeds could germinate under 5–25 ℃. When the constant temperature was 25 ℃, the germination rate of 90% was only need 3 days. Its growth duration was 86–98 days in spring sowing time and 209–244 days in autumn sowing time. Spring sowing of Yanshi–1 in Longjing city, the highest yield was 194.30 g/m2 and the maximum yield of autumn sowing in Dongying city was 223.50 g/m2. The test results of different row spacing showed that the lowest yield (148.10 g/m2) was the treatment of 60 cm×20 cm, it was significantly lower than other treatments. The treatment of 30 cm×10 cm had the highest yield (182.10 kg/m2). The test results of different hole density showed that the treatment of 6 plants each cave had the lowest yield (137.10 g/m2) and the highest yield (187.60 g/m2) was the treatment of 2 plants each cave. The test results of different fertilizer levels showed that the highest yield of Yanshi–1 was 199.60 g/m2 under the lower level of fertilizer. Quality analysis results showed that the crude fatty content, crude protein content and oil yield were as high as 37.80%, 27.40% and 36.22%, respective. The main unsaturated fatty acid contents including linolenic acid, linoleic acid and oleic acid, were 13.05%, 21.8% and 21.65%, respective.
