The reason for D1 is lack of fertilizer , and the melons are all dependent on the oysters . It is good for melons, especially in the period of melons. If the melons are insufficient in fertility and growth is limited, it will cause the physiological phenomenon of late cucumber fruit bending and even severe deformity. . The melons in the melon period, as the fruit grows faster, the demand for fertility is also growing. At this time, if there is no fertilizer, there will be a phenomenon of poor growth. The more ugly the cucumber grows, the more abnormal it is, indicating that the lack of fat is more severe. If the cucumber is only slightly curved, the length and color are normal, it proves that there is not much lack of fat.

The second reason is that the temperature is not controlled . Cucumber is a cold-tolerant crop. Therefore, the greenhouse of 15 to 30 degrees belongs to its comfort zone. When the growth environment is below 10 degrees, the cucumber grows poorly. At the same time, the synthesis of photosynthesis will also deteriorate, resulting in limited growth. Another is the problem of illumination. Everything grows by the sun. The illumination of plants is long, and the photosynthesis is absorbed. The synthesis of nutrients is naturally faster. It is also less prone to the phenomenon of growth-limited fruit bending. Cucumber bending affects quality and sales. Therefore, melon farmers, it is really important to increase greenhouse insulation measures to promote photosynthesis.

The third reason is watering . Cucumber is a water-based vegetable. It needs a lot of water to supplement growth in the later stage of growth. During the flowering period before the melon, or during the period of the knotting, it is not because of more watering, otherwise there will be a phenomenon of fruit enlargement, which directly leads to the fruit bending. The fourth reason is the external force factor. Cucumber is a climbing vine vegetable. When planting, it can be used to make it grow vigorously and win high yield. In the process of scaffolding, if the melons are obstructed by external forces such as ropes and shelves, growth is prone to deformity and bending. In addition, during the growth stage of the cucumber, if it is in contact with or close to the ground, the space will be narrow, which will cause it to bend when it grows.

Experience summary of coping methods : scientific fertilization and reasonable watering; do all the insulation measures; promote photosynthesis; when laying out the vines, pay attention to leaving the growth space of cucumbers and eradicate the effects of terrestrials caused by external forces; It is found that the young melon is not straight, and it is necessary to find the cause of the poor growth in time and actively take various remedial measures. For young melons that have already caused mild bending, the bottom fall can be used to correct the curvature, or it can be treated with a growth regulator. After a few days, the melons that are not bent will straighten. In addition, increasing the planting density, timely sparseness, reducing the yield per plant, can also reduce the phenomenon of bent melon. At present, there are also strong fruit solutions for preventing cucumber bending deformity.

Let's talk about the production problem that everyone cares about: To get high yields, it is necessary to topdress the fertilizer characteristics of the cucumber growing season. Cucumber is planted until the melon is fertilized, which is the pre-growth stage of cucumber less than one month after planting. If the soil temperature is low, too much water is applied to the fertilizer, which will lead to rotten roots. The seedling roots have weak activity and poor absorption capacity, causing excessive water in the soil and causing the roots to rot. Found that the leaves are thin, dull and dull, easy to wilting, it means that the water is poured more, pay attention to the amount of water and fertilizer. The countermeasures are as follows: increase the ground temperature as soon as possible, evaporate some water; re-watering after some time, use the iron shovel to dig some soil around the vines before watering, observe the amount of water in the soil below the ground, and then carry out the thin fertilizer Management of the way.

Fertilization method from cucumber to fruit harvesting period: Cucumber is a crop with shallow roots but more fertilizer. From the young fruit period to the harvesting period, the amount of topdressing should be gradually increased, which can promote the nutrient requirements of fruit development and expansion. Cucumber topdressing in the shed, do not take the method of outdoor cucumber gouging and ditching. To be applied with the ditch, the cucumber needs to be taken care of, and the amount of topdressing per dose is not much. At the peak of picking, a small amount of fertilizer is added to each water, which is a trick to promote high yield. The cucumber melon can not only absorb nutrients from the root soil, but also directly absorb nutrients from the leaf surface. Therefore, adopting foliar spray fertilizer is also a good method for supplementing cucumber to promote nutrient development. In the middle and late growth stages, it is generally not necessary to add pesticides together to the fertilizer and spray them at the same time, which is easy to cause phytotoxicity or drug failure reaction. If necessary, you can take the morning spray method of spraying fertilizer in the morning. When the soil is wet and the temperature is low, it should not be fertilized. This will cause the female flower to differentiate, the flower leaves to fall, and the problem of deformed melon formation. In addition, it is not appropriate to fertilize under conditions of excessive temperature. Under the action of high temperature, the evaporation of water in the leaves is increased, which affects the exertion of fertilizer. Today's sharing is here, I hope to help you grow cucumber.
