Improper fertilization, resulting in uneven growth due to rushing time, the application of chicken manure that has not been fully fermented and fermented as a base fertilizer, causing root damage, is the main reason for the current uneven growth of cucumbers in the area. After some cucumbers are burned, the seedlings are uneven and vary greatly. In addition, there are individual greenhouses that cause uneven growth due to the application of caustic soda in chicken manure, and the rooting caused by chemical fertilizers is mainly caused by excessive application.

Prevention method For the root cause caused by the above reasons, experts suggest: apply fully fermented and decomposed organic fertilizer, and apply as early as possible, during the growth period of cucumber, appropriate application of some biological fertilizer, such as Jianzhibao, Hezhen brand series Organic fertilizer, etc. For the seedlings that are weaker now, you can also use the Harvest No. 1 800 times for root irrigation to promote growth. The amount of chemical fertilizer applied should not be too large, and the amount of each application should not exceed 30 kg. After the temperature is lowered, applying chemical fertilizer will stimulate the root system and cause the plant to be affected. You can choose the fertilizer that can be applied in winter, such as the fertilizer that allows the vegetables to “eat meat and drink soupâ€, chelate the ecological blue fertilizer (composite fertilizer), and potassium nitrate. Fertilizers such as calcium and boron.
The ground is uneven, causing the terrain to be low and uneven during the uneven watering, which makes the plant water supply imbalance, the terrain is high, the water is low, the terrain is low, the water is rich, and many vegetable farmers will also apply some water when watering. Fertilizers, this has caused the situation of uneven growth of plants.
The method of prevention and treatment is leveled and combined with small water pouring. Avoid some seedlings poured, some can not be poured. At the same time, it should be prevented that the water in the front of the greenhouse should not be too much, causing the lack of oxygen in the root system to cause the growth of the roots.
Root-knot nematode harm, resulting in uneven growing indoor shed some root knot line pests and diseases, infection cucumber root, because the varying degree of indoor shed nematodes, severe in some places, some places less, which also makes cucumbers The plants are growing unevenly.
The control method can be carried out by using 1.8% avermectin 2000 to 3000 times. There are vegetable farmers using avermectin, this method can, but the effect is not obvious. It can be root-treated after water, 200 ml of liquid per plant.
When the seedlings are different in size, the situation is less than that caused by the growth of the seedlings. Because the vegetable farmers will have more spare parts during the seedling raising, but when the seedlings encounter serious diseases, the spare seedlings may not be enough. However, if you can't plant it, you will borrow a seedling from your neighbor's house, which will cause the cucumber to grow unevenly.
When the control method is planted, the seedlings should be evenly distributed, and the uneven growth can be controlled by spraying 800 times of the harvest to promote uniform growth.
