Some cucumber growers have blindly increased the amount of pods and leaves, in order to obtain high yields, thus “plundering” plant nutrients, leading to the general growth weakness, yellowing of leaves, shortening of melons, and upward movement of parts of melons during the late growth period of cucumbers. In other cases, the "shut-down" phenomenon of melon topping occurs in severe cases. If you do not strengthen management, the loss is quite serious.

"Stop" reason

Too much fruit in order to increase production, farmers often take improper measures, and all those who can sit and stay in the melon, the excess female flowers are not removed.

Harvesting is not timely Because of the unstable price of the guava, the vegetable farmer has to wait for the high price and leave the melons that have already been picked on the melon pods, causing "falling pods" and excessive consumption of nutrients in the plants.

Improper fertilization Many vegetable farmers have “multiple, chaotic, and miscellaneous” phenomena in their fertilization. In particular, excessive use of compound fertilizers causes excessive soil solution concentrations, resulting in damage to the roots and weakening absorption capacity, which affects the normal growth of plants.

The over-application interval of overdosing drugs is too short and the concentration exceeds the standard. It is easy to form phytotoxicity, causing the leaves of the plants to shrink and the photosynthesis to decline.

Improper watering does not pay attention to the weather conditions. After watering, it encounters even cloudy days, causing the roots of cucumbers to grow up, thereby inhibiting the growth of roots and affecting the growth of the aboveground parts.

Precaution

When the cucumbers of the plants were adjusted, they could not fall too low at once, and the plants were maintained at a height of about 1.5 meters, ensuring that there were more than 15 functional leaves on the plants. For more plants sitting melon, to be properly melon, invisible melon stay, otherwise it is easy to cause the middle and late "rest." The yellow leaves at the bottom should be removed in time to reduce nutrient consumption.

Increase the light even after the sunny day suddenly can not suddenly uncover the grasshopper, should expose the flower buds, so as not to cause flash seedlings.

Fertilizer management in low temperature and low light weather, watering can not be too diligent, flood irrigation. Note that after watering, wait until the temperature in the shed increases to 30°C before releasing the air, and the air outlet should be small to large. Do not blow the air at one time to avoid flashing. Fertilizers are flushed with water and fertilizers containing humic acid or amino acids that are easily absorbed by cucumbers should be used. The amount of one-time use should not be excessive.

Prevention and control of diseases Greenhouse cucumbers are susceptible to downy mildew, brown spot disease, gray mold, and bacterial leaf spot disease. For these diseases, we must adhere to the prevention-based, comprehensive prevention and control approach to ensure that there are no susceptible plants within the shed. When using drugs, the concentration should be strictly controlled. Do not mix three or five kinds of pesticides to reduce the occurrence of phytotoxicity.
