Abstract:

Taking Holand color pepper variety ¡®Mandy¡¯ as material£¬2.5£¬5.0£¬10.0 (CK)£¬15.0 and 20.0 ¦Ìmol/L (they were numbered as N2.5,N5.0,N10.0,N15.0,N20.0)five different nitrogen levels were processed on greenhouse soilless cultivation color pepper£¬the growth£¬yield£¬dry matter and the total nitrogen content were studied.The results showed that£¬plant total nitrogen content in the order was N15.0 £¨1.6148 g)>N20.0 £¨1.5000 g)>N10.0 £¨1.4500 g)>N5.0 £¨1.4132 g)>N2.5 £¨1.3670 g).Plant height under N2.5-N15.0 treatment concentrations range showed the increasing trend with the increase of concentration£¬and concentration range under N15.0-N20.0 processing showed a trend of decline£»leaf number perplant in the order was N10.0>N15.0>N5.0>N20.0>N2.5£»leaf area per plant in the order was N15.0>N20.0>N10.0>N5.0>N2.5.Distribution of nitrogen in various organs of proportion was not affected by the influence of different nitrogen levels£¬and total nitrogen content in different organs were different.Dry matter accumulation in the fruiting period£¬the roots and leaves increased with the increase of nitrogen£¬the fruit increased obviously when nitrogen application was less£¬no obvious difference existed between different processing of stem£»in the mature period£¬stem and leaf decreased with the increase of nitrogen£¬fruit increased with the increase of nitrogen£¬the differences of the root between the groups was not significant.Output in the order was N15.0>N5.0>N10.0>N20.0>N2.5.The results showed that the best nitrogen fertilization level of greenhouse soilless cultivation color pepper was 15.0 ¦Ìmol/L.
