日光温室番茄栽培施硼效应

Effects of Boron Fertilization on Yield,Quality and Physiological Characters of Tomato in Greenhouse

研究了施硼对日光温室番茄栽培产量、品质及一些生理代谢的影响,结果表明,施硼可使番茄早熟、增产,早期产量和总产量分别达35 194,108 059 kg/hm2,较对照分别提高12.3%和13.4%;可改善番茄果实品质,使果实可溶性固形物、还原糖及Vc含量显著提高,使有机酸含量降低;促进了植株生理代谢,使叶片叶绿素含量和光合速率提高,效应以采收盛期和收获结束期最为显著;同时降低了叶片可溶性糖含量。

The experiment was conducted to determine effects of boron fertilization on yield,quality and physiological characters of tomato cultivated in greenhouses.The result showed that early and total yield of boron fertilization plots reached 35 194 kg/hm2 and 108 059 kg/hm2 respectively,12.3% and 13.4% higher than those of the control.The boron fertilization improved quality of fruits.Apart from the decreased organic acid content,it increased soluble solid contents,reducing sugar and vitamin C markedly on fresh basis.It promoted physiological metabolisms,including chlorophyll content and photosynthesis,and the effect was more significant especially at and after harvest peak stages.The boron fertilization decreased soluble sugar contents in leaves as well.
