| Abstract: | Effects of potassium fertilizer on tomatoes in protected field showed that, when 300 kg/hm 2 of KCl was supplied, the yield increased 8730.2 kg/km 2, and 7323.02 yuan/hm 2 of the value of production was obtained. In addition, the maturing stage of tomatoes was earliered by 10 days, the yield and the value of production in prior stages was enhanced by 19.0 % and 20 90 %, respectively. The amounts of Vc, reduction sugar and organic acids of tomato fruits were increased by 24 mg/kg, 0 11 % and 0 04 % compared to the control respectively. The ratio of output to input of potassium fertilizer was 12 21 : 1. |
