Cucumber nutrient management

Cucumber is the annual flowering fruit fruiting many times. hi high temperature, hi water, hi light, hi nitrate nitrogen, hi potassium, its nutrition management is divided into: base fertilizer period, the first flower, the first flowering, the first Fruit, fruit and fruit in the period.

At the end of fertilizer: the general organic fertilizer or farm fertilizer fermentation with the main high-phosphorus fertilizer 8-10KG such as monoammonium phosphate MAP 12-61-00 or diammonium phosphate DAP 21-53-00, and also monopotassium phosphate MKP 00-52-34.

Flower preparing: mainly use high nitrogen fertilizer in NO3 form, dont use NH4 as a replacement of NO3. The formula can be 25-10-10 or 30-10-10. but the temperature of this period to the 20-25 degrees during the day is appropriate, 10-15 degrees at night is appropriate

Flowering: foliar supplement boron spray, the ground can be appropriate impulse potassium dihydrogen phosphate 2-3KG per acre. This period of daytime temperature to 25-30 degrees, 10-15 degrees at night is appropriate The

Fruit: fruit to high potassium-based, especially like potassium nitrate 13.5-0-46, ground water flushing is appropriate and spray foliar calcium nutrient.

Flower with fruit the period: after the first result, the flower be with the fruit in the same time, fertilize in balance type flushing and high potassium flushing, and do this in rotation for 2 or 3times, the foliage in time to add boron fertilizer, fruit for a long time to add calcium fertilizer. This period of daytime temperature requirements of 32 degrees to 35 degrees, 10-15 degrees at night is appropriate.

Note: cucumber like PH5.5-7 slightly acidic soil, if the PH below 5.5, it is recommended to use alkaline water fertilizer to soil, and the cultivation process need to pollinate, drop Man, for the first agronomic measures with the best output value
