Inappropriately fertilized chicken manure was used as a base fertilizer to cause root damage. Individual greenhouses burned roots because of the presence of flaming alkali in chicken manure. Excessive application of chemical fertilizers causes root burning. After some cucumbers were burned, the seedlings were growing unevenly. Control methods: Apply adequately cooked organic fertilizer, and apply as early as possible, reasonable fertilization, during the growth period of cucumber, timely flushing some biological bacterial fertilizers, such as Jianzhibao, Haozhen brand series of organic fertilizers.
When the ground is uneven, the terrain in the greenhouse is low and uneven, which results in unbalanced water supply to the plants. When the terrain is high, the water content is low, and when the terrain is low, the water content is high. In addition, many vegetable farmers also apply some fertilizer when they water, which further increases plant weight. The degree of uneven growth. Control methods: ground leveling, combined with a small water pouring, to avoid some seedlings poured, some seedlings poured less than. At the same time, excessive water in front of the greenhouse should be prevented in order to prevent roots from lacking oxygen to produce roots and cause uneven growth.
Root-knot nematodes endanger the root-knot nematodes in the sheds. Because the root-knot nematodes in the sheds are of different degrees of damage, some are serious and some are lighter, which can make cucumber plants grow unevenly. Control methods: You can use 1.8% abamectin 2000 ~ 3000 times to irrigate the roots, each plant 200 ml liquid.
When planting, seedlings of different sizes occur less often, because friends of vegetable farmers will bred some spare time when growing seedlings. However, when serious diseases are encountered at the seedling stage, the spare seedlings may not be enough, but they must not be used. Planting will plant seedlings, which will cause the cucumbers to grow unevenly. Control methods: 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.
