通过田间试验研究了不同施氮量(0、75、150、225kg/hm^2)与施磷量(0、30、60、90、120kg/hm^2)对油菜花期、阶段性开花数、单花大小、单花开花持续时间的影响,为合理施肥推动油菜花经济提供依据。结果表明,增施氮肥能使油菜始花期提前... 通过田间试验研究了不同施氮量(0、75、150、225kg/hm^2)与施磷量(0、30、60、90、120kg/hm^2)对油菜花期、阶段性开花数、单花大小、单花开花持续时间的影响,为合理施肥推动油菜花经济提供依据。结果表明,增施氮肥能使油菜始花期提前和延长终花期,各施氮比不施氮处理延长花期23.2%~31.8%,且随着氮肥用量的提高有花期延长的趋势。施氮增加单株油菜整个生育期开花数131.6%~276.4%;增加花瓣长9.53%~15.96%,提高单花重1.07%~5.87%;延长单花开花持续时间1.96%~4.79%;除油菜整个生育期开花数在施氮225kg/hm^2时达到最大值外,以上开花性状均在施氮150kg/hm^2效果最好。增施磷肥能使油菜初花期提前并延长油菜终花期,随着磷肥用量的提高,各施磷比不施磷处理延长花期27.8%~50.4%;施磷增加单株油菜整个生育期开花数377.4%~736.7%;增加花瓣长8.01%~17.05%,提高单花重11.15%~31.82%;延长单花开花持续时间0.23%~2.15%;除施磷120kg/hm^2处理花期最长,整个生育期开花数最多外,以上开花性状均以施磷90kg/hm^2处理效果最好。在本试验条件下,施氮150kg/hm^2对延长油菜花期,提高单花性状效果最佳;施磷90kg/hm^2对增加油菜开花数,提高单花性状效果最佳。 展开更多

[Objective] The aim was to compare differences of SPAD value, chloro- phyll content, agronomic characters, economic characters and yield traits to analyze correlation of SPAD value with other indices and establish regression functions. [Method] Based on 34 Brassica napus L. varieties, SPAD value, chlorophyll content, agronomic characters, economic characters and yield traits were measured and re- gression functions were established according to correlations. [Result] SPAD value, chlorophyll content, agronomic and economic characters and yield traits all achieved significant level in differences among 34 varieties. Specifically, SPAD value was of extremely significant correlation with chlorophyll a and b, total chlorophyll and carotenoid, and the correlation from high to low was chl-b〉chl-z〉chl-a〉chl-x. SPAD value was of significantly positive correlation with total pod number per plant, plant height, seed number per pod, yield per plant and harvest yield, and of insignificant correlation with branch point height, effective branch number, pod density of main stem, and pod length. [Conclusion] It is simple and rapid to predict chlorophyll con- tent, economic characters and yields of Brassica napus L. with SPAD value and re- gression functions. 展开更多

Field experiments were conducted during 2008-2010 to investigate the ef- fects of NPK fertilization on seed yield and economic benefit of a new hybrid cultivar of winter oilseed rape (Brassica napus L.) - Xiangzayou763, and to determine the optimum NPK ratio and dose in Hunan, China. The results showed that NPK ratio (1:0.50:0.50) with 180 kg/hm2 N, 90 kg/hm2 P2O5 and 90 kg/hm2 K20 was the optimum combination for the highest seed yield (2 231.13 kg/hm2) and economic benefit (9 816.97 Yuan/hm2), of which 1 641.23 Yuan/hm2 being set for fertilizer in- vestment (VCR=4.11). Besides, the effects of N, P and K fertilizers on seed yield and oil production of winter oilseed rape were not identical. N had the greatest ef- fect on plant growth of winter oilseed rape, followed by P and K. Total leaf number, green leaf number, leaf length and width, rhizome diameter, branch number, dry weight per plant and other agronomic characters in high N treatments were higher than those in low N treatments. By correlation and path analysis of yield components, the contribution rate to seed yield was found: effective silique number per plant〉seed number per silique〉l 000-seed weight. 展开更多
