Select good varieties to avoid the use of dark green leaves as far as possible, because the dark green leaves of cucumber, its high bitter content, should choose a lighter leaf color varieties.
Control of optimum temperature When the temperature or ground temperature is lower than 13°C, cell permeability decreases, nutrients and water absorption are inhibited, and cucumbers are susceptible to bitterness; greenhouse temperature higher than 30°C and too long duration can lead to bitter cucumber.
Less nitrogenous nitrogen fertilizer promotes dark green color and should be applied less. Can be cooked more organic fertilizer and phosphorus and potassium fertilizers. Do not mix chicken manure when applying manure, because of the high nitrogen content of chicken manure, easy to make cucumber taste bitter.
Balanced fertilization should be balanced with fertilization, and the ratio of ammonia, phosphorus and potassium should be 5:2:6. Foliar application of rare earth micro-fertilizer, spraying once at seedling stage, initial flowering stage and young stage; spraying urea solution on foliar; spraying 0.5 kg of urea per acre and 150 kg of water per acre after full flowering and full fruit period Foliar spraying cytokinin, spraying cucumber cytokinin 2 to 3 times before and after flowering.
Irrigation of magnetic water A magnetizer is installed at the outlet of the pump, which is the magnetization of the irrigation water. Watering the magnetized water prevents bitters from accumulating in the melon and avoids bitterness.
When the fumigation smoke in the shed is 2 to 3 true leaves in the seedlings, light smoke (burning of straw, straw, etc.) is placed in the shed, and 2 to 3 days of closed airtight time can increase the number of female flowers and increase the number of strong melons and reduce bitterness accumulation.
Preventing root damage will increase the bitter taste of cucumbers. Seed sowing on the production of sand plate sowing, rooting to minimize root damage, sub-plastic application of plastic nutrient pods or paper pockets, cultivation should be as far as possible mulching mulching film cultivation, when the land should be slightly deeper early, later slightly shallow.
The Fluorine-Containing Benzoic Acid series is very common form of the fluorochemical compounds, it has many product types and derivatives. Most of products are in white crystalline powder, some of products are Colorless monoclinic prismatic crystals. It was widely used as fungicide intermediates, also used in the etching process. The Fluorine-Containing Benzoic Acid series are mostly in high value-added , less polluting products. We are trying our best to make our production dock with market to give accurate and effective services for the market .
