Cucumber moderate growth is what reason
Light reason
In autumn delay cucumber cultivation management, because the light is stronger, many farmers friends using sun-shade net or sprinkle the mud and cool shade, but if there is a sun-shade net cover for a long time not jie, sprinkle the mud excess use improper conditions will lead to insufficient light and moderate growth.
The temperature reason
Cucumber growth of optimum temperature for 25 to 30 degrees Celsius, if more than 30 degrees Celsius, cucumbers are prone to moderate growth phenomenon, especially the night temperature is too high, moderate growth phenomenon for serious.Therefore in the process of management, to strictly control the temperature, reduce consumption of plant respiration, increase organic nutrient accumulation, reduce moderate growth occurs.
Humidity causes
Normal growth and development of cucumber suitable humidity around 85%, due to the airtight PengShi cultivation environment, humidity is bigger, often humidity above 90%, if the humidity is over 85%, moderate growth phenomenon easy to cause the plant, humidity above 90%, moderate growth phenomenon is serious.So should timely adjust humidity control PengShi, prevent cucumber moderate growth.
Fertilization reason
To cucumber fertilization, balanced fertilization, avoid by all means is too single nitrogen fertilizer, if too much nitrogen, moderate growth phenomenon, it is easy to cause plant should timely supplement some under phosphorus, supply plant nutrient elements needed, in order to reduce the moderate growth.
Moderate growth how to control the cucumber
Preventive measures:
Water control, reasonable application of nitrogen fertilizer, strictly grasp the timing of the first open water fat.Master the appropriate management of temperature and suitable temperature difference between day and night.
Moderate growth in the event of prevention and cure: waist adopt comprehensive measures to save, mainly include:
(1) in foliar spraying is equal to the normal use of the concentration of 1.7 to 2 times micronutrient fertilizer (leaf fertilizer) or some nutrition therapeutic agent, such as: 200 ~ 250 times liquid of green wind 95 (normal use concentration was 400 times liquid).High concentrations of liquid or liquid fertilizer could lead to deformation, leaves a temporary but once back, there will be unexpected control moderate growth and promote the effect of the female flowers.
(2) can pick heart temporarily inhibition of root activity, looks like the control of the plant.
(3) pay attention to the temperature of the management, reduce the management of the temperature at night, from the lowest temperature of 12 ℃ to around 8 ℃, 5 ~ 6 days in a row, caused the big temperature difference between day and night, as far as possible to control the stem leaf growth, promoting the transformation of the direction of growth to reproductive growth.
(4) to avoid excessive heat, to fully ventilated take a breath, maintain appropriate temperature and humidity, reduce the water content in the cucumber leaf, to inhibit the growth of plant.
