Measures to prevent bitter cucumber

November 09, 2018

Carefully selected. "Momordica" is hereditary. For example, fruits with bitter taste are used as melon seeds. Fruits produced in the next generation will still have bitter taste. For this reason, when the cucumber is about to mature, it needs to take a little surface tissue and taste it with the mouth. If there is bitterness, it cannot be selected as a melon seed. Be sure to choose a fine variety with no bitter or bitter substance content. Rational fertilization. Seedling stage should control the application of nitrogen fertilizer to avoid plant growth. By the end of the flowering period, nitrogen fertilizer supply will need to be strengthened. The absorption of nitrogen, phosphorus, and potassium by cucumber is basically 5:2:6. Too much nitrogen fertilizer will cause the plants to lose their fertility balance. This will not only lead to leggy and poor fruit setting, but will also increase bitterness. Control moisture. Drought should be avoided. In the summer when the temperature is high and the soil moisture is low, the plants will have a "physiological dryness early," so that more "bitter elements" will enter the fruit. In addition, the roots of cucumbers are shallowly ploughed into soil and cannot be hydrated. In high-temperature weather, it is necessary to properly irrigate water in order to maintain sufficient moisture in the plough layer. Keep the temperature. When the ground temperature is below 13 degrees Celsius, nutrients and moisture are affected. At this time, there will be more bitter melons. If the ground temperature reaches 30 degrees Celsius and the duration is too long, bitterness will increase. Strengthen management. Brackets should be set up according to local customs and try to increase the light between the plants. The tied vines are usually carried out after 30 centimeters in length, and are tied every three or four knots. When the Lord is full, he must take care of it. Strengthening scientific management in the field will also greatly reduce the occurrence of bitter melons.
