How to reduce cucumber "big head" and "pointed mouth"

Recently, many cucumber growers have reported that there are many occurrences of cucumber tipped cucumbers and big head cucumbers, which seriously affect the effectiveness of cucumbers.

Both the big head and the pointed mouth are abnormal cucumbers. The poor flower bud differentiation and nutritional deficiency are two major causes of its occurrence. First, because the melon flesh growth at the top of the melon strip is closely related to the development of the internal seeds, if the reproductive growth is blocked, the flower bud differentiation process will be disordered or the pollination will be uneven. If the pollination is too concentrated, the probability of emergence of big head melons is greater; otherwise, the number of sharp-billed melons will increase. Second, if the melon strips lack water and fertilizer in the early stage, there will be plenty of melons in the later stages;

To reduce the cucumber head and melon, we must pay attention to the following points in the management: First, a reasonable temperature control, especially the night temperature. It is 25-28°C during the day and 13-15°C during the night. Increase the number of female flowers to ensure flower bud differentiation quality. Second, we must rationalize fertilization and cultivate roots and protect the roots. Rational fertilization according to the fertilizer requirement of cucumber, to meet the demand of nutrient for cucumber in different growth periods; to protect the root system and ensure the supply of nutrients. Third, we must protect the leaves to ensure the supply of organic nutrients. For example, cucumber downy mildew can be sprayed with pharmaceuticals such as Prodig, Dimethomorph, etc.; Bacterial angular spot can be sprayed with copper preparation or streptomycin; Whitefly can be treated with acetamiprid or imidacloprid.
