The Causes of Cucumber Growing Abnormally and Countermeasures
Inappropriate Fertilization Causes Poor Growth Due to the rush, the use of chicken manure that has not been adequately decomposed as a base fertilizer causes rooting, which is the main reason leading to the uneven growth of cucumbers. After some cucumbers were burned, the seedlings were growing unevenly. In addition, there are individual greenhouses where the growth of chicken manure is caused by the presence of flaming alkali, which is mainly caused by excessive application volume.
Control methods: Fully fermented and decomposed organic fertilizer should be applied and applied as early as possible. During the growing period of cucumber, some biological bacterial fertilizers, such as Jianzhibao and Jizhen brand organic fertilizers, should be properly applied. For the seedlings with weaker growth, it is also possible to use the harvest No. 1 800 times solution for rooting and promote growth. Fertilizer application amount should not be too large, and the amount of flushing can not exceed 30 kg per time. Irregularities caused by uneven ground The terrain in the shed is low and uneven, which results in unbalanced water supply to the plants. When the terrain is high, there is less water, and if the terrain is low, the water is too much. In addition, many vegetable farmers will also apply part of the fertilizer when watering. Caused the situation of plants growing uneven.
Control methods: leveling the ground, water pouring, to avoid the emergence of some seedlings, and some can not be poured. At the same time, it should prevent the growth of water in the shed and cause the growth of the roots.
Root knot nematode damage caused by growing sheds have root knot nematodes invading the cucumber roots. Due to the varying degrees of damage caused by nematodes, some areas are serious and some are lighter, which can also make cucumber plants grow unevenly.
Control methods: There are vegetable farmers using avermectin flushing, this method is not obvious. Can be used 1.8% of avermectin 2000 to 3000 times to irrigate, each strain 200 ml liquid.
When planting, the size of the seedlings caused by the uneven growth caused less occurrences, because the vegetable farmers will breed more nursery part of the reserve. However, when serious diseases are encountered at the seedling stage, the spare seedlings may not be sufficient, and they will be planted at the neighbors by seedlings, which causes 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.
