黄瓜发苦是因其植株内有一种叫苦味素C的物质。就目前的黄瓜品种来看,绝对没有苦味的黄瓜品种是不存在的,因此,应选择苦味稍轻的黄瓜品种,同时重视栽培措施的合理运用。1.温度。当气温或地温低于13摄氏度时,细胞渗透性降低,养分和水分吸收受到抑制,黄瓜易出现苦味:大棚温度高于30摄氏度且持续时间过长也会导致黄瓜发苦。因此要尽量增强保护设施的增温保温性能,调好温度,避开苦味
Bitter cucumber because of its plants there is a substance called bitterness C material. The current cucumber varieties point of view, absolutely no bitter cucumber varieties does not exist, therefore, should choose a bit lighter cucumber varieties, while paying attention to the rational use of cultivation measures. Temperature When the temperature or ground temperature is below 13 degrees Celsius, cell permeability decreases, nutrient and water absorption is inhibited, cucumber susceptible to bitter: greenhouse temperature is higher than 30 degrees Celsius and duration can cause cucumber bitter. Therefore, we should try our best to increase the temperature and heat preservation performance of the protection facilities, adjust the temperature and avoid the bitterness
