Abstract:

Objective】To explore the optimal ratio of water and fertilizer for ultra-late sowing wheat in northern Xinjiang and solve the problems of low yield and low utilization rate of water and fertilizer resources for ultra-late sowing wheat in local agricultural production. 【Methods】With the local main plant Xindong 18 as the test material, three irrigation treatments and four urea treatments were wet up: W1 (2,750 m3/hm3), W2 (3,750 m3/hm3), W3 (4,750 m3/hm3), N0 (0 kg / hm3), N1 (180 kg/hm3), N2 (360 kg/hm3), N3 (5,400 kg/hm3), to analyze the effects of different water and nitrogen transportation on wheat growth, water and nitrogen utilization, dry matter accumulation and yield.【Results】The increase of irrigation volume and nitrogen application could increase wheat plant height and leaf area index. Compared with W1N0, W2N2 mature plant height increased by 13.22 cm, and the leaf area index by 3.92 m2/m2. The accumulation of dry material in wheat increased from jointing-filling-slow, and W2N2 treatment was significantly higher than those of other treatments; On the basis of W2N2, the consumption of soil water and the amount of nitrogen, and the yield was also reduced, leading to the decrease of water use efficiency. Under W2N2 treatment, the water utilization rate was 20.71% higher than that of W3N3, and the agricultural utilization rate of nitrogen fertilizer was 64.14%; the number of ear grains increased with the increase of irrigation water and nitrogen application, N2 was significantly higher than those of N0 and N1 treatments, the 1,000 grain weight increased with the increase of irrigation water, W3 treatment was significantly higher than that of W1 treatment, decreasing with the increase of nitrogen application, and reaching the maximum at W3N0. The yield of W2N2 (9,743.01 kg/hm2) was the highest and significantly higher than those of the other treatments.【Conclusion】The yield of ultra-late sowing winter wheat is 3,750 m3/hm2 with urea content 360 kg/hm2, which is the best combination of both yield and efficiency.

摘要:

目的】探究新疆北疆超晚播小麦最适水肥配比,为农业生产中提高超晚播小麦产量及水肥利用率提供参考。【方法】以当地主栽新冬18号为供试材料,设3个灌水处理W1(2 750m3/hm3)、W2(3 750m3/hm3)、W3(4 750m3/hm3),4个施氮肥量(尿素)处理N0(0 kg/hm3)、N1(180 kg/hm3)、N2(360 kg/hm3)、N3(5 400 kg/hm3),分析不同水氮运筹对小麦生长、水氮利用、干物质积累及产量的影响。【结果】增加灌水量和施氮量,有利于小麦株高及叶面积指数增大,与W1N0相比,W2N2成熟期株高显著增高13.22 cm,孕穗期叶面积指数显著增高3.92 m2/m2;小麦单株干物质积累量从拔节-灌浆呈先快后慢的增长趋势,W2N2处理显著高于其它处理;在W2N2基础上随着灌水量和施氮量的增加显著降低小麦对土壤水分的消耗量,且产量也同时降低,进而导致水分利用效率降低。在W2N2处理下,水分利用率较W3N3高20.71%,氮肥农学利用率高64.14%;穗粒数随灌水量和施氮量的增加而增加,N2显著高于N0、N1处理,千粒重随着灌水量的增加而增加,W3处理显著高于W1处理,随施氮量的增加而降低,在W3N0达到最大。W2N2(9 743.01 kg/hm2)产量达到最高,且显著高于其它处理。【结论】超晚播小麦灌水量在3 750 m3/hm2追施尿素含量在360 kg/hm2时冬小麦干物质、水氮利用效率及产量最佳,是产量和效益兼优的最佳组合。
