在种植黄瓜的过程中,时常出现苦黄瓜,该怎样控制呢?一、严格控制留种瓜苦味黄瓜能遗传,所以,在黄瓜将要成熟时,选取表层部分瓜品尝,选择无苦味的瓜留种。二、平衡施肥幼苗期应控制施用氮肥,然后逐渐增加氮肥用量,到开花结果盛期,黄瓜对氮、磷、钾吸收的比例基本上是5∶2∶6,氮肥过多或磷、钾肥过少时较易产生苦味。三、避免高温地温在30℃以上的高温期持续太长时,苦味瓜会增多,应控制温度。四、避免干旱
In the process of planting cucumbers, often appear cucumbers, how to control it? First, strictly control the remaining cucumber melon cucumber can be genetic, so the cucumber will be matured, select the surface layer of melon taste, choose no bitter melon stay species . Second, balanced fertilization Seedling should control the application of nitrogen fertilizer, and then gradually increase the amount of nitrogen fertilizer to the flowering peak, cucumber nitrogen, phosphorus and potassium absorption ratio is basically 5: 2: 6, excessive nitrogen or phosphorus, potassium over Less prone to bitter taste. Third, to avoid high temperature Ground temperature in the high temperature above 30 ℃ for too long, the bitter melon will increase, the temperature should be controlled. Fourth, to avoid drought
