The latest course of field management techniques and methods of watermelon
There are many varieties of watermelons, but the planting methods and field management techniques are basically the same, but if you want high yield of watermelons, you should pay a little attention to the field management. so what kind of field management can make the watermelons big and sweet? Next, the pro-agricultural network will introduce to you the field management technology of watermelon.
1. Watering
Watermelons need a lot of water to grow. It is said that 80% of watermelons are water and the rest are sugar, so watermelons are made of water. In the whole growth process of watermelon, it needs to be watered about five times, the first time is after sowing, the second time is after the melon seedlings break through the soil, and the third time is when the strong seedlings are fertilized, that is, when the seedlings grow to 40 to 50 centimeters long. the fourth time is the flowering period, this watering is very important, it is related to the success rate of fruit setting, so the western medicine will water the land thoroughly, and the last time is when the watermelon grows to the size of the palm. This watering must be fully watered, to ensure that its water supply until the watermelon mature, at the same time, the last time the water can not be too much, watermelon needs to accumulate sugar, if too much water, ripe watermelon will not be sweet.
2. Fertilization
Watermelons need to be fertilized at least four times from planting to maturity, with an average of 2,000 jin of farm manure per mu as base fertilizer. secondly, if you are in rural areas, you can use livestock manure to wave human feces and urine water. This kind of fertilizer is the best for the absorption of watermelons, but if it is planting in a greenhouse or soilless cultivation, appropriate amounts of chemical fertilizers should be used, such as no more than 10 jin of nitrogen fertilizer at a time. If the potassium fertilizer is not more than 100 jin, the phosphate fertilizer is not more than 50 jin, and the compound fertilizer is not more than 45 jin, the nutrient solution of soilless cultivation also needs to be diluted or increased according to different growth periods.
3. Pruning vine
When the watermelon seedlings grow to about 60 centimeters, we need to move the watermelon seedlings in one direction, then remove the tip of the main vine of the watermelon, and get rid of the weeds in the field. In general, many side branches will grow in about ten days of dancing, and so the side branches will be removed in the same way to a certain extent. Finally, when flowering, if there is more than one melon in a section of the vine, then you need to remove one word and keep only one. The second is that if there are flowers, the flowers need to be removed to reduce unnecessary nutrient consumption, so that watermelons can be high-yielding and grow rapidly.
4. Pollination
In general, watermelons do not need artificial pollination, for example, there are more insects in sunny days, so they can be pollinated by insects, and the efficiency is also very high, but if the flowers encounter the rainy season and the insects seldom come out, if the flowers are pollinated, the flowers will wither, then there will be what people call the phenomenon that branches blossom without bearing fruit. Artificial pollination is mainly by collecting pollen, then spraying it or applying feathers on the female flower to make it pollinate evenly.
5. Anti-cracking melon
The phenomenon of cracking watermelons is very common, and it often occurs when watermelons are about to mature, so it is very infuriating. Once cracked melons mean that they cannot be sold and can not make money, then how to prevent and cure cracked melons? first of all, when the watermelon grows to the size of the palm, we put a layer of straw under the watermelon to stop itching to keep the temperature unchanged, and secondly, the light intensity is strong. So you need to cover the surface of the watermelon with a layer of grass, and then don't move the watermelon or touch it during field management. Finally, the water in the field must be managed well, too much or too little water will appear cracked melon phenomenon.
