What planting methods can improve watermelon quality
Watermelon is a fruit that everyone loves to eat, and it has a very large market in China and is welcomed by many people. Therefore, the current watermelon planting area is very large, but many melon growers find during cultivation that watermelons can develop various poor qualities such as not being sweet and having thick rinds, which seriously affects watermelon sales. So when we plant watermelons, how can we improve watermelon quality? Let's take a look together below!
1. Prune in time
Watermelon vines have a very strong growth capacity. If pruning is not done well, the field ventilation and light penetration will decrease, excessive nutrients will be consumed, and nutrient accumulation in the watermelon fruit will be affected, causing quality to decline. Therefore, when planting watermelons, we must pay attention to doing a good job of pruning to avoid overly vigorous vine growth. Ensure the growth of the watermelon plant and promote fruit setting. After the vines grow to about 35 cm, keep some strong-growing vines and remove excess side vines and secondary vines in time.
2. Scientific fertilization
Fertilizer is very critical to watermelon growth. During the growth process, the demand for potassium fertilizer is the greatest, followed by nitrogen and potassium. When fertilizing, in order to ensure that the nutritional needs of watermelons are met, attention should be paid to applying more farmyard manure. Then note that chlorine fertilizer must not be applied, otherwise it will cause the watermelon to die. Then we should pay attention to properly spraying foliar fertilizer, especially half a month before harvest. This is because at this time the root capacity of the watermelon plant has gradually declined, nutrient absorption has decreased, and the leaves gradually turn yellow, affecting photosynthesis. The sugar content in the fruit will also decrease because of this, so we must do a good job of spraying farmyard manure and foliar fertilizer to improve watermelon quality.
3. Water reasonably
Watermelon growth has a very large demand for water, so during the process of planting watermelons we must do a good job of water management. Water reasonably to meet the water needs of watermelon growth. However, in the later stage of watermelon growth, pay attention to reducing the amount of watering, especially 7 days before watermelon harvest, and be sure to strictly control it. If there is too much water, it will not only cause adverse phenomena such as fruit cracking in watermelons, but also cause the sweetness of watermelons to decrease. Therefore, in the later stage, if too much water is applied and the rainy season is encountered, drainage must be carried out in time.
4. Enhance photosynthesis
The sweetness of watermelon is determined by the content of various sugar substances such as sucrose and glucose. The formation of these sugar substances in watermelon requires the watermelon to have relatively strong photosynthesis. So when planting watermelons, improving the photosynthetic capacity of watermelons is an important measure to ensure watermelon sweetness and also to improve watermelon quality. Therefore, when planting, we should pay attention to strengthening management, pruning appropriately, improving field ventilation and light penetration, and ensuring that all leaves can receive light evenly. Only in this way can the photosynthetic capacity of watermelons be effectively improved.
The above is a brief introduction to how to improve watermelon quality. The quality of watermelons has a very large relationship with sales and price, so everyone must pay more attention when planting. That is all for today's introduction.
