Cucumber fertility cycle 1, the germination of sowing to the first true leaves appear, usually 5-7 days, growth at this stage is small, slow freshest cucumbers, need a higher temperature, humidity and plenty of light, promoting early emergence , emergence uniformity cucumbers, to prevent excessive growth. 2, seedling leaf from the first true leaf expanded to 4-5, it normally takes about 30 days. This phase begins differentiation, but the center is still growing roots, stems, leaves and other vegetative organs. Management objectives and promote the combination of control, nurturing seedlings. 3, early flowering (fat trees stretch of vine) from 4-5 true leaf to the first female cucumber melon Zuogua largest wholesale market, it takes about 20 days or so, then the vegetative and reproductive growth at the same time, vegetative growth center gradually converted from the reproductive growth best-selling cucumber varieties should promote control in combination, promote Zuogua control excessive growth. 4, fruiting period from the first female Zuogua to pull seedlings, duration due to different cultivation methods and different. This stage of plant growth slowed to fruit and flower bud development for the center. It should supply adequate water and fertilizer, promote fruiting and prevent premature aging. To avoid bitterness in cucumber cultivation process, should be selection of resistant varieties, removal deformity melon. Cucumber bitterness is - physiological diseases, mainly due to the bitter elements caused by excessive accumulation in melon, cucumber varieties mainly constraints, water, fertilizer, temperature and plant affected by the strength or the like, it gives rise to vomiting, diarrhea, cramps and other symptoms of poisoning. The disease that is specific humid microclimate impact, mainly in the root melon and melon full bloom early flowering of late. According to the test, and production of the main control methods are: 1, the selection of resistant varieties. 2, timely removal of non-commodity value of deformity melon. 3, balanced fertilizer. Increased basal composting facilities, in 50 kg basic fertilizer applied per acre superphosphate, promote fertilization techniques, flowering follow NPK 5: 2: 6 ratio fertilizer, foliar spray of 0.3% growth late phosphodiesterase potassium. 4, to avoid drought. When the temperature is high, less soil moisture, it is easy to make plant physiological drought occurs, to timely irrigation.
