How to water cucumber seedlings?

Water is essential to the growth of crops. It is not only a carrier of nutrients and energy, but also directly affects the normal growth, flowering and fruiting of crops, as well as the quality of fruits. In cucumber cultivation, water management is the key link to achieve high quality and high yield. So how do you water cucumber seedlings?

Water management after cucumber seedlings emerge plays a fundamental role in later growth. The goal of cucumber cultivation is to achieve high profitability, which is usually achieved through high yields and high prices. Early market launch is one of the important measures to increase prices, so moisture management should focus on promoting early market launch and more fruit.

The opening time and number of female flowers of cucumber are affected by variety and management, among which water management is particularly critical. Cucumber flower bud differentiation begins when the first true leaf emerges, and by the time the true leaf unfolds, the flower bud has differentiated to the 12th node. At this time, the gender of the flower bud has not yet been determined. Whether it will eventually form a female flower or a male flower depends on the amount of nutrients produced by photosynthesis transported to the flower bud. Adequate transportation is conducive to the formation of female flowers, which appear early and in large numbers.

By strengthening water management, the transport of nutrients to the floral organs can be regulated and the formation of female flowers can be promoted. In terms of specific management, in order to make the female flowers appear early and in large numbers, water should be properly controlled after the cucumber seedlings emerge from the soil. Too much water will promote vegetative growth, lead to leggy seedlings, reduce the transport of nutrients to the floral organs, and be detrimental to the formation of female flowers. Water control can create an appropriate water deficit environment and induce the transport of photosynthetic products to the floral organs.

The timing of watering after cucumber seedlings emerge can be determined by observing the performance of the leaves. If the true leaves wilt for more than an hour at noon, watering is required. Water thoroughly to allow the water to fully penetrate the nutrient matrix.

The watering time should be chosen between 9 and 10 in the morning. After watering, as the temperature rises, you can ventilate the surface of the substrate to evaporate the water, reduce humidity, and reduce the occurrence of diseases.

To prevent excessive growth, you can spray potassium dihydrogen phosphate and other supplementary potassium fertilizers and phosphorus fertilizers to inhibit excessive growth of cucumber seedlings and promote the differentiation of female flowers.

In short, water management after cucumbers emerge should reasonably control water supply based on the growth needs and environmental conditions of cucumbers, so as to meet the growth needs of cucumbers and avoid problems caused by excessive water, laying a good foundation for high yield and high quality of cucumbers.
