| 摘 要： | 为探究北疆滴灌条件下复播大豆高产栽培适宜的施磷量,以大豆品种黑河45号为试验材料,在大田滴灌条件下,设置0(P0)、60(P1)、120(P2)、180(P3)和240 kg·hm-2(P4)5个施磷水平,研究施磷量对复播大豆叶绿素含量(SPAD值)、叶面积指数(LAI)、干物质积累与分配、产量及经济效益的影响。结果表明,施磷量对复播大豆叶绿素含量的影响不显著;各处理复播大豆LAI在生长前期效果不明显,但苗后30 d 依次表现为P3>P2>P1>P4>P0;在大豆各生育时期,中等施磷处理的干物质积累量及分配比例均优于其他处理,总体依次表现为P3>P2>P4>P1>P0;实际产量以P3处理最高,且各处理的平均产量为2 526.34 kg·hm-2,较P0处理显著增产22.70%;P3处理的纯收益最高,为4 637.9 元·hm-2,较P0、P1、P2和P4处理分别提高86.19%、28.59%、4.17%和57.52%。综合考虑复播大豆的生长发育、产量及经济效益,得出适宜的施磷量应控制在120~180 kg·hm-2之间。本研究结果为伊犁河谷地区复播大豆合理施磷肥提供了一定的理论依据。

| Abstract: | To ascertain the appropriate amount of phosphorus for high-yield summer-sowing soybean cultivation under drip irrigation in northern Xinjiang, the soybean variety Heihe 45 was used as an experimental material and five phosphorus application levels: 0 kg·hm-2, 60 kg·hm-2(P1), 120 kg·hm-2(P2), 180 kg·hm-2(P3) and 240 kg·hm-2(P4) were conducted under drip irrigation in the field to research the impacts of different phosphorus fertilization application on chlorophyll content (SPAD), leaf area index (LAI), dry matter accumulation and distribution, yield and economic benefits. The results showed that the effect of phosphorus application on chlorophyll content of summer-sowing soybean was not significant. The effect of different treatments on LAI in the early growth stage of summer-sowing soybean was not obvious, but followed the trend of P3>P2>P1>P4>P0 after 30 days of the seedling. At each stages of soybean, the accumulation and distribution of dry matter in medium phosphorus application were better than other treatments, and the order was P3>P2>P4>P1>P0. The yield was the highest at P3, and the average yield of each treatment was 2 526.34 kg·hm-2, which increased by 22.70% than that of non-phosphorus application P0. The highest net income of P3 was 4 637.9 yuan·hm-2, which increased by 86.19%, 28.59%, 4.17% and 57.52% than that of P0, P1, P2 and P4, respectively. Based on comprehensive analysis on growth and development, yield and economic benefits of summer-sowing soybean, it proposed that the appropriate phosphorus application should be controlled between 120 kg·hm-2 and 180 kg·hm-2. These results provided a theoretical basis for suitable phosphorus application amount for the local summer-sowing soybean. |
