Pay attention to the "sharp melon" of the over-summer cucumber after rain

April 14, 2024

Cucumber pointed problems are mostly related to nutrient supply, and combined with recent weather conditions and water and fertilizer conditions, cucumber pointed heads are mostly caused by insufficient supply of organic and inorganic nutrients. On the one hand, the over-summer cucumber experienced a high temperature stage after planting and failed to lay a good foundation for the root system, which led to a decrease in the absorption capacity of the root system for inorganic nutrients; Two factors together led to the occurrence of pointed melons.

For the above two factors, we must pay attention to nutritional supplements in the management of cucumbers:

First of all, the supplement of mineral elements should be started from two aspects. One is to maintain the root system that absorbs nutrients. When watering, products with functional ingredients such as chitin, amino acids, humic acid, and algae extract can also be washed, and the amount of beneficial bacteria can also be increased, which can promote root growth while inhibiting bacteria. . When the root system is particularly bad, a strong rooting agent can be used. The second is to supplement mineral nutrients. In rainy weather, the watering interval and watering amount should be properly extended. The mineral element fertilizers used should also be appropriately reduced. The number of foliar application of total nutrient element fertilizers should be increased.

Second, supplement the foliage with organic and inorganic nutrients. Because there are many problems in watering under rainy weather, the quality and frequency of foliar supplement can be increased. One is to supplement organic nutrients in time, such as amino acids and algae extract. The second is to supplement mineral nutrition, you can choose a large amount of water-soluble fertilizer containing vitamins.
