增施二氧化碳气肥有助于提高蔬菜的产量,获得较高的经济效益,但必须掌握二氧化碳施肥的合理时机。利用YT—2型二氧化碳气肥发生器进行二氧化碳追肥时,应根据不同蔬菜品种,不同生长发育期以及温度、光照条件确定使用量。二氧化碳浓度过高会对蔬菜作物造成毒害;二氧化碳浓度不足则影响蔬菜作物的光合作用,使同化物的积累减少,影响产量。如菠菜、茄 Adding carbon dioxide gas fertilizer will help increase the yield of vegetables, access to higher economic benefits, but must grasp the reasonable timing of carbon dioxide fertilization. The use of YT-2 carbon dioxide fertilizer fertilizer carbon dioxide fertilizer, should be based on different vegetable varieties, different growth and development and temperature, light conditions to determine the amount used. High levels of carbon dioxide can cause toxic effects on vegetable crops; insufficient levels of carbon dioxide can affect the photosynthesis of vegetable crops, reducing the accumulation of assimilates and affecting yields. Such as spinach, eggplant
