In February of this year, our company conducted hole seeding and seedling cultivation of cucumbers in the experimental field of the farm, planting a total of 100 varieties with the aim of observing the growth status of these cucumber varieties. After more than two months of water and fertilizer management, the cucumber vines have now grown and borne fruit.
In February of this year, our company conducted hole seeding and seedling cultivation of cucumbers in the experimental field of the farm, planting a total of 100 varieties with the aim of observing the growth status of these cucumber varieties. After more than two months of water and fertilizer management, the cucumber vines have now grown and borne fruit. On Monday and Friday of this week, our company's personnel observed and picked cucumbers, measuring the length, coarseness, individual fruit weight, taste, and yield of various varieties of cucumbers. In the following months, we will conduct more than ten measurement records on cucumbers and organize various data of cucumber varieties to screen out the varieties that customers need.
The most important thing to pay attention to in summer greenhouse cucumber cultivation is watering. Cucumbers require high humidity and are susceptible to various diseases and pests. In order to ensure the normal growth of cucumbers, it is not only necessary to pay attention to water management, but also to avoid the breeding of diseases and pests, ensuring that cucumber yield does not decrease but instead increases. When watering cucumbers, pay attention to the following points:
Firstly, the timing of watering in summer is crucial. The temperature is high during the day, so it is best to choose watering in the morning and evening, and avoid watering at noon. Watering on a sunny morning helps maintain soil moisture, helps cucumber roots absorb water, and promotes the growth of vines. Watering in the evening, with relatively high temperature and good ventilation conditions, helps to lower ground temperature and accumulate nutrients, while avoiding diseases that may be caused by high humidity. Taking all factors into consideration, watering in the morning and evening can help increase cucumber yield.
Secondly, in summer, cucumbers should be watered in moderation, adhering to the principle of "frequent watering with small amounts of water" and avoiding the use of flood irrigation with large amounts of water. Overflooding can easily lead to high soil moisture, causing root rot and causing various pests and diseases. In addition, flood irrigation can also cause waste of water resources and reduce water utilization efficiency. Therefore, in cucumber cultivation, especially in summer, it is recommended to use low water and frequent watering to avoid excessive watering leading to a decrease in yield and quality.
In summer, watering cucumbers also requires mastering scientific principles and adopting different watering strategies based on different growth stages of cucumbers, namely controlling and promoting supplementary watering. According to the growth of cucumbers, adjust the watering frequency and amount reasonably. The situations where cucumbers need to control water include: firstly, if the leaf radius exceeds 5 centimeters, the stem node length exceeds 7 centimeters, and the stem and leaf growth rate is too fast; Secondly, if the leaves are infected with diseases, watering should be stopped to lower the surface temperature and avoid excessive growth of seedlings and vines; The third reason is that the leaves are large and thin, and the number of fruits is small. Watering should be controlled to slow down the growth rate of the aboveground parts and promote the growth of cucumber roots. The situations that require water supplementation include: firstly, if the concentration of pesticides is too high during spraying, it is necessary to immediately replenish water and take sun shading and moisturizing measures; The second is that the leaves are curled and not stretched, and cucumbers lack luster, requiring timely hydration; Thirdly, after fertilization of cucumbers, timely hydration is also necessary to facilitate the absorption of fertilizer efficiency.
Finally, watering cucumbers in summer should be done in stages. During the cucumber planting period, it is necessary to ensure that the root system can take root in the soil and obtain sufficient nutrients. Within a week after planting, appropriate watering should be applied to slow down the seedlings and promote their rapid development, resulting in the formation of melon strips. During the cucumber harvesting period, the frequency and amount of watering need to be adjusted based on factors such as the size of plants and leaves, and the number of melon strips. In the later stage of cucumber harvesting, due to the decrease in plant growth rate, the watering frequency should be moderately reduced.
In general, watering cucumbers in summer should follow the principles of moderate, timely, and scientific watering. When watering, scientific water and fertilizer management should be adhered to, combined with the growth characteristics of cucumbers, to maximize fertilizer efficiency. Through reasonable watering management, the yield of cucumbers can be increased and they can grow more vigorously.
