Key Points of Watermelon Cultivation Techniques
Compared to the cultivation techniques and simple knowledge of growing watermelons at home for most people, let's take a look at the following together.
Recently, field investigations in watermelon fields have shown that most of the management has not kept up. It is necessary to adopt scientific field planting management measures and pay attention to the following technical points for high yield and efficiency.
1. Watermelon Cultivation: Emphasizing the application of fruit-setting fertilizer.
This should be completed before the watermelon reaches the size of an egg. It is recommended to use a high-potassium compound fertilizer, usually 30 kilograms per mu. It is also suggested to add 5 kilograms of humic acid fertilizer per mu, which is beneficial for improving the quality of the watermelon. Fertilization should be done at dusk on sunny days or can be applied with irrigation water.
2. Watermelon Cultivation: Disease and Pest Prevention.
Watermelons are susceptible to many diseases and pests throughout their growth, such as wilt disease, blight, leaf spot disease, aphids, and red spiders. It is essential to adhere to the principle of prevention first and mainly prevention. If it is too late to apply pesticides after seeing the outbreak of diseases and pests, it would be futile. Immediate comprehensive spraying for prevention is necessary. For diseases, use mancozeb plus kasugamycin, and for pests, use appropriate pesticides. It is also recommended to add potassium dihydrogen phosphate "Fertilizer King" at a concentration of 0.5% to the prepared pesticide solution as a foliar fertilizer, which can significantly improve the sweetness and taste of the watermelon.
3. Watermelon Cultivation: Ditching for Drainage.
This April to May, our town has had more rainfall than usual, with less sunlight and high soil moisture content, which is not conducive to the normal growth of watermelons, affecting both yield and quality. Therefore, it is necessary to repair the "enclosing ditches" in the watermelon fields, open "waist ditches" and "bed ditches," and dredge the "three ditches" to ensure no standing water in the field after the rain stops.
4. Watermelon Cultivation: Pruning and Pressing Vines.
Usually, a 2-3 vine pruning method should be adopted. That is, when the main vine reaches 30-40 centimeters, keep 1-2 lateral vines as sub-vines at the base, and remove all other lateral vines. Pay attention to delaying or reducing pruning for weaker-growing seedlings. Also, pressing the vines is necessary after fruit setting, focusing on pressing twice before and after the fruit, or you can press three times only after the fruit. Growers should be careful not to damage the leaves or bury them when pressing the vines.
The above information about key points of watermelon cultivation techniques and the methods and steps of growing watermelons at home is complete. I hope it helps you, and I also hope that everyone comes to see more green plant and flower experience and common sense!
