Reading guide:Nowadays, growing cucumbers in greenhouses in winter is not a new technology. However, in the process of planting, cucumbers can frequently have the problem of "turning melons". This must be paid attention to, the impact on the output is still relatively large. The reason for this must be found, otherwise the later ** plan is not right, and it will be in vain. As for the factors of planting cucumbers and turning melons in winter greenhouses, I personally briefly summarized a few points, hoping to be of some help to planting netizens.
Cucumbers are grown in greenhouses, and melons are turned into melons. The first is to see how well the plant grows, if the plant itself grows relatively slender. Basically, it can be concluded that it is due to the poor growth of the plant itself. Especially in the case of 3-5 fruits at the same time, the melon rate is more obvious.
Solution: The cucumber plant itself grows relatively weakly, which leads to the problem of melon melting. The solution is also relatively simple, increase the temperature in the greenhouse, try to be about 20 degrees at night and about 25 degrees during the day, this step is only to improve the growth temperature. Then it is necessary to increase the topdressing of fertilizer, try to choose water-soluble fertilizer that is easy to absorb, especially for zinc sulfate, which is conducive to the growth of cucumbers and promotes the growth of branches and leaves. Finally, if there is a lot of fruit set, the fruit is thinned, and there are 1-3 large fruits.
The plant grows weakly and turns into melon, which is malnutrition. And if the plant grows too vigorously, it will also have the problem of turning melons. The two phenomena have become a stark contrast, and the melon has grown into melons. The most basic thing is that the leaves are large and the petioles are long, and in this case, the vegetative growth is too vigorous, which directly leads to the inhibition of reproductive growth, which is the problem of melon.
Solution: In such a situation, it is necessary to control the amount of nitrogen fertilizer used. Excessive nitrogen fertilizer is prone to overgrowth. In addition, it is necessary to lower some temperature, control the amount of water, and if necessary, spray inhibitors, and basically control the growth of the population. There is a solution to the process of homogenizing vegetative growth and reproductive growth.
For the growth of melons, especially in the middle and late stages, that is, the time period with the highest fruit. The potassium and phosphorus needed are the most, and the situation of melon has a lot to do with potassium. If the potassium absorption is low or the potassium fertilizer is insufficient, melons will also occur.
Solution:In the case of potassium deficiency in the production process, the fastest way to supplement potassium is to spray potassium fertilizer, which generally chooses potassium dihydrogen phosphate. The speed of spraying potassium supplementation is the fastest, and the soil should also be top-dressed, but the amount of phosphate fertilizer and nitrogen fertilizer must be controlled, otherwise it will affect the absorption of potassium, and the professional term antagonism. Generally, soil top dressing is used in high-potassium compound fertilizer, which is why it is for this reason.
Regarding the phenomenon of melon transformation caused by disease, this is the easiest to distinguish. Generally, you can see the appearance of diseases on cucumbers, such as: spots, downy mildew and so on. For diseases, only drugs can be used**. Especially if it has already happened, it is necessary to use pesticides. For different diseases, you can choose the corresponding drugs.
Growing cucumbers in a greenhouse, it is also not an easy task. The appearance of cucumbers turning into melons is only one of the more common problems. However, there will be a variety of factors that will cause it, and this requires rich planting experience while finding a solution. And what I shared today is only one of the more common factors and corresponding solutions, I hope it will be helpful to netizens who grow cucumbers in greenhouses. In addition, what I talked about inappropriately, you can also correct it in the comment area, which is also an opportunity to learn.
