播期对萝卜农艺性状·产量·物质积累和采收期的影响

Effects of Sowing Date on Agronomic Traits,Yield,Material Accumulation and Harvest Period of Radish

以“百日子”萝卜为试材,设置6个播期处理(9月6日、9月14日、9月22日、9月30日、10月8日、10月16日),研究不同播期对“百日子”萝卜农艺性状、营养物质积累和采收期的影响。结果表明,随着播种日期的推后,萝卜产量先增加后下降,9月14日和9月22日播期处理的萝卜植株生长充分,产量高,果形标准,抗坏血酸和可溶性固形物含量高,木质素含量低,品质佳;9月14日播种处理萝卜果实表型和营养品质变化较小,采收期可长达28 d。综合分析各播期下“百日子”萝卜农艺性状、产量、品质和采收期,“百日子”萝卜的适宜播期为9月14—22日,最迟播种期为9月30日。

Six sowing dates(September 6th,September 14th,September 22nd,September 30th,October 8th,and October 16th) were set up to study the effects of different sowing dates on the agronomic traits,nutrient accumulation and harvest period of ‘Bairizi' radish.The results showed that with the postponement of the sowing date,the yield of ‘Bairizi' radish first increased and then decreased.The ‘Bairizi' radish plants sown on September 14-22 grew fully,had high yield,high fruit shape standard,high ascorbic acid and soluble solids content,low lignin content and good quality.Radish fruit phenotype and nutritional quality sown on September 14 had little change,and the harvest period could be as long as 28 days.According to the comprehensive analysis of the agronomic traits,final yield,fruit quality and harvest period of radish under each sowing period,the suitable sowing period of ‘Bairizi' radish was September 14-22,and the latest sowing period was September 30.
