【Four key techniques for planting watermelon】 Recent field inspections in watermelon fields have found that most of the management is not keeping up and scientific field planting management measures should be taken. Paying attention to the following technical points is conducive to high yield and efficiency.
1. Watermelon planting: Apply a heavy dose of fruit-setting fertilizer.
This should be completed before the watermelon fruit reaches the size of an egg. It is recommended to use a high-potassium compound fertilizer, generally 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 watermelon. The fertilizing time should be chosen on a sunny evening or can be applied with water irrigation.
2. Watermelon planting: Pest and disease prevention.
There are many pests and diseases in the life cycle of watermelon, including wilt disease, blight, leaf spot disease, aphids, red spiders, etc. It is necessary to adhere to the principle of prevention first and mainly. If you wait until the outbreak of pests and diseases to apply pesticides, it will be too late and futile. It is currently urgent to carry out a comprehensive spray prevention. For diseases, use mancozeb plus kasugamycin, and for insect pests, use targeted medications. It is also recommended to add potassium dihydrogen phosphate "Fertilizer King" at a concentration of 0.5% to the prepared medicine solution as a foliar fertilizer, which can significantly improve the sugar content and taste of watermelon.
3. Watermelon planting: Ditching for drainage.
This April to May, our town has had more rainfall, less sunlight, and high soil moisture content, which is not conducive to the normal growth of watermelon, affecting both yield and quality. Therefore, it is necessary to repair the "surrounding ditches", 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 planting: Pruning and pressing vines.
Generally, a 2-3 vine pruning method should be adopted. That is, when the main branch grows to 30-40 centimeters, retain 1-2 lateral branches at the base as sub-vines, and remove all excess lateral branches. Pay attention to delaying or reducing pruning for weaker-growing seedlings. At the same time, pressing vines should be carried out after fruit-setting, focusing on pressing twice before and after the fruit, or pressing three times only after the fruit. Planters should note that pressing vines should not injure the leaves, nor should leaves be buried.
The above introduction on how to plant watermelon and detailed explanation of watermelon cultivation techniques is hoped to bring some knowledge of flowers and plants to green plant enthusiasts.
