| 摘 要： | 用盆栽试验研究了不同水肥调控对辣椒不同生育期生物量、养分吸收状况及产量的影响.结果表明:辣椒生育前期水肥调控对生物量影响不大,中后期随着水肥条件的改善,植株生物量呈明显增加趋势.当水分亏缺时,根系生长受阻,其生物量下降,生长明显受到抑制,导致辣椒产量减少.水肥调控对构成辣椒产量的性状均有不同程度的影响,从而导致椒果产量在不同水肥条件下的差异.在相同的水肥条件下N和K的含量依次为叶>果>茎,而P的含量则是果>叶>茎.

| Abstract: | Hot pepper 089 was tested in a pot experiment to study effects of different water and fertilizer regulation on its biomass at the different growth period,nutrient absorption and yield.The results showed that there was not the obvious effect of water and fertilizer regulation on its biomass in the early growth period,its biomass obviously increased with improvement of water and fertilizer condition in middle and later period.The growth of the root system was inhibited when water was short,which affected plan... |
