不同覆盖方式和灌水量对甘蓝生长、品质及产量的影响

Effects of Different Coverings and Irrigation Quantities on Growth,Yield and Quality of Cabbage

以生产上的经验灌水量30 m3/667m2-未覆膜(G0-N)为对照,研究不同覆盖方式和灌水量对甘蓝生长、品质和产量的影响。结果表明:随着灌水量的减少,未覆膜处理植株的茎粗、叶球膨大率呈下降趋势;覆膜处理的植株呈现上升趋势;VC,可溶性糖,粗纤维均随着水量的减少而增加,甘蓝的品质提高;10 m3/667m2-覆膜处理的产量最高,其次是20 m3/667m2-未覆膜,而30 m3/667m2-覆膜与10 m3/667m2未覆膜产量最低。综合产量和品质指标,在该试验中,认为20 m3/667m2-未覆膜和10 m3/667m2-覆膜可以使甘蓝达到高产优质。

Using conventional irrigation 30 m^3/667m^2 no plastic film mulching as control,cabbage growth,quality and yield were investigated under different coverings and irrigation quantities,respectively.The results showed that the plant stem diameter,horizontal diameter by no plastic film mulching decreased with the decline of irrigation;conversely,the treatments by plastic film mulching increased.VC,soluble sugar and crude fiber increased with the decline of irrigation.10 m^3/667m^2 with plastic film mulching led to the highest yield,followed by 20 m^3/667m^2 with no plastic film mulching,30 m^3/667m^2 with plastic film mulching and 10 m^3/667m^2 with no plastic film mulching led to the lower yield.Integrated the properties of cabbage yield and quality,in this experiment,20 m^3/667m^2 with no plastic film mulching and 10 m^3/667m^2 with no plastic film mulching,could result in high yield and quality of cabbage.
