"If you don't top dressing up vegetables, it's like raising a son without teaching. Lao Wang often joked with his neighbors like this. Of course, he understands the importance of top dressing. Lao Wang still remembers that he had just planted tomato seedlings in the spring of that year, and he was excited to think that he must have a good harvest. But all summer, he was so busy watering and weeding that he completely forgot about top dressing. 
In autumn, Wang was disappointed to see that his tomato plants were slender and weak, so he bore a few bunches of tiny tomatoes. This incident made Lao Wang realize that reasonable topdressing directly affects the yield and quality of vegetables. Timely supplementation of fertilizer can enhance the ability of vegetables to use sunlight and allow leaves to fully photosynthesizeIt can also expand the root area and enhance the absorption of soil nutrients, and if you do not top dress, vegetables will grow stunted and have poor results due to lack of nutrients. Since then, Lao Wang has made up his mind to become an expert in top dressing. He bought a large number of agricultural books and studied the growth patterns of different vegetables in detail. During the day, Lao Wang kept practicing, comparing, and summed up a set of scientific and reasonable vegetable topdressing magic weapons. 
Now, Lao Wang's vegetable field is full of life all year round, and the abundant tomatoes and verdant cabbage make him proud. Maybe one day, Lao Wang will publish a best-selling book to teach all enthusiasts his experience in topdressing. To become a good vegetable farmer, the importance of top dressing is like educating your son well, and it must not be ignored. Lao Wang's first topdressing strategy was aimed at tomatoes, cucumbers and other continuous fruiting vegetables in his vegetable field. After much thought, he decided to fertilize these vegetables for the first time as they transitioned from vegetative to reproductive growth. It was a sunny morning in mid-June, and Wang came to the vegetable patch humming a little song, and suddenly saw that the tomatoes he had planted had begun to bear fruit, and there were a few small tomatoes hanging on the plants. 
So Lao Wang quickly prepared a water-soluble fertilizer with a suitable ratio of nitrogen, phosphorus and potassium, and carefully watered each tomato into the soil. At the same time, Lao Wang also found that his cucumbers had begun to extend their vines, and the roots of the gherkins that had begun to grow had also appeared as beginners. Lao Wang judged that cucumbers have also entered the growth period and need to be fertilized for the first time to promote the fruit. In the days that followed, Lao Wang continued to observe the growth of these continuous fruiting vegetables. When the tomato grows the second fruit, Lao Wang once again judged that it was a good time for top dressing;When the yield of cucumbers began to skyrocket, Lao Wang also added fertilizer in time. Through such repeated careful judgment and top dressing, Lao Wang's vegetables have more and more fruits, and Lao Wang is also happy. In addition to continuous fruiting vegetables such as tomatoes and cucumbers, Lao Wang's vegetable field is also full of vegetables such as cabbage and pumpkins that are harvested at one time. For these vegetables, Lao Wang has also developed a unique topdressing strategy. 
At noon that day, the scorching sun was in the sky, and Lao Wang was going to build an awning in the pumpkin patch in the vegetable field. He found that the pumpkins he had planted had grown very tall, and the two largest were the size of a child's head. So Lao Wang put down the work of the awning and first watered the pumpkin with a carefully proportioned high-potassium fertilizer. Ten days later, seeing that the largest pumpkin was already the size of a bucket, Lao Wang once again judged the second time for the pumpkin to be topdressed. With such additional fertilizer, Lao Wang finally harvested a large pumpkin weighing dozens of catties. In terms of topdressing cabbage, Lao Wang also judged the two best times based on experience. In vegetable topdressing, it is also very important which fertilizer to choose. Lao Wang has studied this very deeply. 
A single nitrogen, phosphate or potassium fertilizer is not enough, you must choose a compound fertilizer that contains a variety of nutrients and has a reasonable proportion!"Lao Wang often taught his neighbors. Once, Xiao Zhang, a neighbor, took a fancy to a particularly cheap nitrogen fertilizer on the market, and bought a large bag to apply it to his vegetable plot at one time. As a result, if you accidentally overdose, the root system of the vegetable will be burned, and the consequences will be more tragic. Lao Wang suggested that Xiao Zhang and other vegetable farmers choose some professional and scientifically developed compound fertilizers, the ratio of nitrogen, phosphorus, potassium and trace elements in them is carefully designed, and there will be no problems. Now there are many special fertilizers for the growth period of various types of vegetables on the market, and Lao Wang has carefully studied them. 
You see, this bag is for tomato top dressing, and this bag is for cabbage in the balling stage. It's all good fertilizer!"Lao Wang often shows people his fertilizer collection. Choose the right type of high-quality top dressing fertilizer, so that Lao Wang's vegetables are good all year round. Over the years, Lao Wang has accumulated rich experience in vegetable topdressing. He tried to pass on these valuable lessons to the young people in the village, hoping that they would take shortcuts and not repeat their own detours. "In order to pursue high yields of vegetables that bear fruit continuously, it is necessary to frequently top dressing according to the yield to ensure that the plants receive a continuous supply of nutrients. Lao Wang patted the high-yield tomatoes he planted and told everyone. 
However, for vegetables harvested at one time, the number of topdressing does not need to be too much, and it is enough to master their key growth period, and 1-2 times of strategic topdressing with reasonable fertilizer. Lao Wang shared his experience while inspecting his ripe cabbage. In the selection of fertilizer, Lao Wang insists on using scientific and systematic compound fertilizer. "A single nutrient element is not the best choice, and it is necessary to choose a special fertilizer with a reasonable proportion of nitrogen, phosphorus and potassium trace elements. Now there are more and more ** on the market, you might as well try it. 
Originally, Lao Wang's vegetable topdressing book could already be published. He often said with a smile that when the onions and carrots in his vegetable field also achieved ultra-high yields, he must summarize his experience in growing vegetables into a book, called "Lao Wang's Top Dressing Treasure Book".
