培育壮苗是黄瓜高产高效的基础,而温度调控是黄瓜育苗成败的关键。实践证明,采用四段调控育苗是黄瓜培育壮苗的重要技术措施: 第一阶段 播种到开始出苗。应控制较高的畦温,促使快出苗。一般温度控制在25～30℃。如果连续数天低于10℃,往往会因温度低、畦土过湿而发生烂种。在适宜温度下,2～3天就开始出苗; 第二阶段:从出苗到第一片真 Nurturing strong seedling cucumber is the basis of high yield and efficiency, and temperature control is the key to the success or failure of cucumber seedling. Practice has proved that the use of four regulatory nursery seedlings cucumber is an important technical measures to cultivate seedlings: the first stage of planting to start emergence. Should control the high temperature, prompting fast emergence. The general temperature control at 25 ~ 30 ℃. If the number of consecutive days less than 10 ℃, often due to low temperature, soil over wet and rotten species. In the appropriate temperature, 2 to 3 days began to emerge; second stage: from emergence to the first piece of true
