Effects of"Jincunqiu"Foliar Fertilizer on Growth and Quality of Flowering Chinese Cabbage
In order to explore the application effect of"Jincunqiu"foliar fertilizer on flowering Chinese cabbage(Brassica campestris L.ssp.chinensis var.utilis Tsen et Lee),its effects on growth and quality char-acters of'Youlyu 501'flowering Chinese cabbage were studied by setting different concentrations and using indoor constant temperature hydroponic cultivation.The results showed that the biomass,contents of chloro-phyll,protein and total amino acids,and mineral nutrient accumulation of flowering Chinese cabbage plants were increased by spraying different concentrations of"Jincunqiu"foliar fertilizer,and most of the increase amplitude reached the significant level,but the number of bolting was decreased.The growth characters,nu-tritional quality and mineral nutrient accumulation of the flowering Chinese cabbage reached the best level un-der T2 treatment(2 000 times liquid of"Jincunqiu"foliar fertilizer),which was suitable for producing high-yielding and good-quality flowering Chinese cabbage.But T3 treatment with 1 000 times liquid of"Jincunqiu"foliar fertilizer could inhibit the plant height,stem diameter,economic yield,above-ground dry weight and chlorophyll content.Therefore,under the conditions of hydroponic cultivation in facilities,spraying 2 000 times liquid of"Jincunqiu"forliar fertilizer had the best effects on growth and development,quality improve-ment and mineral element accumulation of flowering Chinese cabbage.
