As an important economic vegetable crop, cucumbers require constant monitoring of their growth by growers. However, a common problem encountered during cultivation is that cucumber seedlings may not grow properly. What are the reasons for this? Let's take a look.
1. Seed problem
For example, problems such as seed quality issues, excessive storage leading to insect infestation, spoilage, or ineffectiveness, as well as poor seed maturity after harvesting and scorching of the germ during seed drying, can all affect subsequent growth. It is recommended to carefully select high-quality seeds before sowing.
2. Soil issues
Heavy, infertile, or severely saline soil can hinder cucumber seedling growth. Cucumbers typically prefer fertile, loose, and well-drained soil. The ideal soil pH is between 6.0 and 7.0, rich in organic matter and nutrients.
3. Fertilization issues
First, insufficient fertilization will cause the seedlings to stop growing due to lack of nutrients. Second, if the organic fertilizer is not fully decomposed or is poorly decomposed, it can burn the seedling roots during fermentation, hindering growth. The preventative measure is to fertilize appropriately and at the right time to meet the seedlings' growth needs.
4. Watering issues
Watering melon seedlings too frequently is generally not advisable. Excessive watering can easily damage their root system, which in turn will affect the growth of the entire plant.
5. Temperature issues
Cucumbers prefer warm environments, with an ideal growing temperature range of 20-30℃. Growth may be inhibited if temperatures are too low or too high. It is recommended to schedule planting according to local climate and season.
6. Pests and diseases
Cucumber seedlings have delicate leaves and are very vulnerable to pests and diseases. If management is not careful, poor ventilation after transplanting, and high humidity in the greenhouse can easily lead to various pests and diseases, thus affecting growth. Common pests and diseases include anthracnose, whiteflies, and aphids. It is recommended to treat them as early as possible based on the specific symptoms.
