Cucumber grows "misaligned" and causes

Improper fertilization Due to rush, the use of chicken manure without sufficient fermentation and decomposition as a base fertilizer, resulting in root injury, is the main reason leading to uneven growth of cucumber. After some cucumbers were burned, the melons grew unevenly and they varied greatly. The burning of roots caused by chemical fertilizers is mainly caused by excessive application volume. Prevention and control measures: Apply fully fermented and decomposed organic fertilizer, and apply as early as possible. During the growth period of cucumber, apply some biological bacterial fertilizer, such as Jianzhibao and Jizhen brand organic fertilizer. For young seedlings with weaker growth, harvested roots can be harvested using Harvest No. 800. Fertilizer application amount should not be too large, and the amount of flushing can not exceed 30 kg per time.

The ground is uneven and the terrain is low and uneven. When watering, the water supply to the plants will be uneven. There will be less water at high elevations, and water will be low at low elevations. In addition, many vegetable farmers will also apply some fertilizer when they are watering, which will also cause The situation of plants growing uneven. Prevention and control measures: Level the ground, and combine groundwater with small water. Avoid some seedlings pouring, and some can't be poured. At the same time, the excessive water in the front of the greenhouse should be prevented to prevent the growth of roots from causing the lack of oxygen.

Root knot nematodes have larvae in the shed where root knot nematodes harm the roots of cucumbers. Because the degree of harm to the nematodes in the sheds is not uniform, some areas are serious and some are light, which can make cucumber plants grow unevenly. Control measures: 1.8% of avermectin 2000 to 3000 times can be used to irrigate roots. Each bottle is filled with 200 ml of liquid medicine.

The occurrence of different sizes of melon seedlings at the time of planting is less frequent, because friends of vegetable farmers will educate more when they grow seedlings. However, if serious disease epidemics are encountered at the seedling stage, spare melon seedlings may not be enough, but they must not be used. When planting, it is possible to borrow seedlings for planting, which causes the cucumbers to grow unevenly. Prevention and control measures: When planting, the seedlings should be evenly distributed, and the uneven growth can be controlled by spraying the harvested No. 1 800-fold liquid to promote uniform growth.
