Plant growth regulators can be used to control cucumber seedlings at the seedling stage. When cucumber stubble grows to half shelf, it is recommended that the growth potential be controlled by regulating the environment, fertilizer, and water, because the use of regulators may affect flower bud differentiation and subsequent results. First, the temperature difference between day and night should be increased. When cucumbers appear to be long, the temperature inside the shed should be regulated first. Under normal circumstances, during the day, the temperature in the shed should be controlled between 25°C and 30°C, at night between 12°C and 15°C, and the temperature difference should be maintained at about 15°C. Second, we should pay attention to water control fertilizer. Before the cucumber is colonized, the base fertilizer applied includes a large amount of nitrogen fertilizer, and it is generally not necessary to top-dress the fertilizer after planting until the result. It is also possible to bend overgrown cucumber heads to make them grow downwards, reduce their apical dominance, promote the transport of cucumber carp nutrition to cucumbers, slow down the growth of the tops, and achieve the purpose of controlling grain production.
