What are the common problems in planting greenhouse cucumbers? How to strengthen management?

At present, the price of cucumber in the greenhouse is reduced, and the enthusiasm of vegetable farmers is also decreasing. This led to a series of problems with cucumbers in the greenhouse, the top of the melons was larger, and the other places were thinner, and the plants also had symptoms of pulling the melons. According to Xiaonong.com, the problems in cucumber planting are more common, mainly due to the lack of careful management.

First, the common cause of cucumber problems in the greenhouse

1. Excessive control, the normal growth of plants is inhibited.

The temperature of cucumber is higher after planting, and the growth of the plant is relatively strong. In order to promote the flower bud differentiation and the number of results is guaranteed, the vegetable farmers generally apply the increase of melon or ethephon, because this year's high temperature period is somewhat long. Ling or Ethephon can effectively control the growth of the plant, but in this year's case, the vegetable farmers sprayed 3-5 times to increase Guaring, so that the normal growth of the plant was inhibited, but the number and time of fruit set did not correspond. Variety.

2. When the price of cucumber is high, leave too much melon.

At the time of summer-autumn handover, the price of cucumber is relatively high. Under the influence of interest, the vegetable farmers blindly stalk and leave melons, which causes the growth of plants to be greatly affected.

3. After the price of cucumber is reduced, the vegetable farmers are more negligent in management.

In particular, the application of fertilizer is much reduced, which causes the plant to further weaken and the yield and quality of cucumber to be further reduced.

Second, how to strengthen the management of cucumber cultivation?

In response to the above situation, it is recommended that farmers' friends strengthen management from the following aspects:

1, reasonable to stay melon, appropriate tree

In the current situation of low cucumber prices, it is recommended that vegetable farmers change the way of staying melons, properly retaining melons, and enhancing the concentrated supply of organic nutrients, which can significantly improve the quality of melons. What's more important is that less melon can give the plant a breathing space, promote the growth of the plant to grow stronger, and then meet the demand for nutrients. In the case of less melons, we should remove the scorpions and tendrils in time to reduce the consumption of nutrients.

2, root promotion

In the case of poor plant growth, taking root and root protection measures is undoubtedly the best way to restore the growth of plants, which requires farmers to water and fertilize in time to prevent the soil from being too dry, pay attention to the application of biological fertilizer when watering In order to achieve the dual role of promoting rooting and providing nutrition.

When the results are more, attention should be paid to increasing the application of nitrogen and potassium fertilizers, promoting the growth of plants and melons, and spraying the water-soluble fertilizers better.
