黄瓜产量高,生长期及结果期也很长,露地栽培的黄瓜生长期约需90—120天左右。整个生育周期分为:发芽期、苗期、初花期及结果期等四个时期。其中从发芽至苗期(4—5片真叶)阶段的生育特点,虽然以根茎叶的营养生长为主,但是花芽已经分化,所以它已开始进入营养生长与生殖生长并进时期。从初花期至结果期即从初花期至收获末期,其生长特点以生殖生长为主,这一阶段黄瓜生长以瓜及秧并茂,并且由于连续地开花、结果及收获,所以整个生育期它不仅吸收养分种类多数量大,而且养分一边被吸收一边被摘瓜时带走,所以养分耗费量大。因此,不仅要掌握生长特点,并且还
Cucumber yield is high, the growth period and the result is also very long, open-field cultivation of cucumber about 90-120 days growth period. The entire birth cycle is divided into: germination, seedling, early flowering and the results of four periods. Among them, the reproductive characteristics from germination to seedling stage (4-5 true leaves) are mainly vegetative growth of rhizomes and leaves, but flower buds have already differentiated, so it has entered into the period of vegetative and reproductive growth. From the early flowering stage to the final stage, from the early flowering stage to the late stage of harvesting, the growth characteristics are dominated by reproductive growth. In this stage, the cucumber grows with melon and seedling, and because of the continuous flowering, fruiting and harvesting, it is not only the whole growing period Absorption of large number of nutrient-rich species, and nutrient absorption while being picked melon away, so nutrient consumption. Therefore, not only to grasp the growth characteristics, but also
