One, improper fertilization Improper use of chemical fertilizers or application of chicken manure without adequate decomposed fermentation as base fertilizer can result in burning of the roots, causing the seedlings to grow unevenly. 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. Fertilizer should not be applied to the roots of cucumber, should be 10 cm away from the roots of cucumber, to prevent the excessive application of fertilizer or fertilizer concentration is too concentrated caused by the roots of cucumber seedlings, resulting in uneven growing phenomenon. For young seedlings with weaker growth, harvest 800 can be used to harvest roots and promote growth. Fertilizer application amount should not be too large, and the amount of flushing can not exceed 30 kg per time. Second, the uneven surface The low-lying and uneven nature caused the water to be high in the high terrain when watering, and the water in the low-lying areas made the plant water supply unbalanced. In addition, many vegetable farmers also applied some fertilizers when they were watering, which also caused the plants to grow unevenly. Prevention and control measures: Leveling the ground, combined with water pouring, avoiding pouring of some seedlings, and some pouring, and preventing excessive water accumulation at the front face of the greenhouse, resulting in the lack of oxygen in roots to produce roots and causing growth. Not homogeneous. Third, the root disease Root diseases of cucumber, such as blight, root rot and blight, can also cause uneven growth of cucumbers. Some sheds have root-knot nematodes and invade the roots of cucumbers. Because the larvae in sheds have different degrees of damage, some are serious and some are light, which can make cucumber plants grow unevenly. Control measures: Root diseases should be started in advance to prevent them. After the colonization of cucumbers, the roots can be rooted with 30% of Hymex Agent 1000 times solution or 3% of Kukuling 750 to 1000 times solution. Nematode control can be used 1.8% of avermectin 2000 ~ 3000 times Irrigation, the effect is better. Fourth, seedlings are not the same size when planting The size of the mixed planting when planting causes the cucumber to grow unevenly. Prevention and control measures: Before the planting, the seedlings should be sorted and graded, and the seedlings should be evenly distributed, so that the big seedlings and seedlings can be planted and planted. Irrespective of the cause of the cucumber seedlings uneven, in taking the appropriate remedial measures, the vine must be adjusted to a height when the vine to promote balanced growth of cucumber.
