Zhao Zhen, a vegetable farmer who hit Gongzhuang Village in Fengnan District of Tangshan City, planted 3 sheds this year. He had planted tomatoes, melons, green peppers, and autumn cucumbers. He grew vegetables for 11 years and he was an old vegetable farmer. He was also a half expert, but this winter cucumber was hard for him. The cucumber scorpions in his shed. The shrinkage was not long. It was not in a hurry to seek help from Zhang Xinqing, a researcher at the Institute of Plant Protection of the Tangshan Academy of Agricultural Sciences through WeChat. Zhang Shangqing believes that this is a physiological problem caused by the low temperature and the lack of illumination, and he has provided guidance on this issue. Zhao: Teacher Zhang, I planted vegetables for more than 10 years. I used to grow tomatoes, melons, green peppers, and autumn cucumbers. This year I had three more greenhouses. The first time I planted winter cucumbers. The sick man is sick, his head is squat, not long! Really anxious, you are quick to see what is going on? (Figure 1) Zhang: Big sister, you see that this melon and flower are on top of the growing point. This is a typical flower topping or melon topping. It is also a phenomenon that the northern winter cucumber is very easy to appear. Look at the pictures in the scorpion is mainly due to two reasons: First, the roots stay too early, and the whole plant stay too much melons, scorpions have not grown up, they fall a big cucumber, so that management will cause nutrient supply Insufficient, the small melon that comes out later is malformed malformed melon. Management must not be the same as Spring and Autumn, see melon to stay. You are a strong female breed. If you look at this strain, the 4th leaf leaves a root melon. Each section has a melon, which is not sparse. The scorpions are so tired that they have small stems and leaves. This way, the lice will be exhausted. How long melon! It's equivalent to letting a child pick up 100 pounds. He doesn't have a lot of energy. Of course, it doesn't work. You let him grow up and you can pick 100 pounds. (Figure II) Zhao: I understand raising children. I understand this time. Isn't this the first year of winter cucumber? Do not know this, look at melon, which is willing to pick ah? Say it is to know that picking does not work! Zhang: You must be willing! Or do you want to sell to whom? The second reason is the cause of the climate. In winter, the temperature is low and there is less light. What time do you open the curtain in the morning? Zhao: Around 10 o'clock. Zhang: What time is the curtain? Zhao: From 3:30 in the afternoon to 4 in the afternoon. Zhang: You see that the total daylight is less than 6 hours, plus the time when the haze is serious, and often the day is open. The illumination time is too short, the time for the leaves to make nutrients is short, and the efficiency is too low. You have to drop so many small melons, and there is no point of nutrient supply growth to form melons. Zhao: That teacher, do I still have the rule of law? I want to pull it off. Zhang: You are not serious yet. You can take care of it slowly and you can continue to grow cucumbers. Zhao: Then do you hurry to talk about it? Zhang: First, these days, sunny days, you first sparse melon, remove the excess melon, according to the growth of the dumplings to stay in the melon, you can make this bitch better 3 to 4 knots to stay a melon, almost 5 to 6 Festival to stay one, just like the 4 leaves left root melon that, root melon early pick, above the small melons are destroyed, first protect the dumplings, the dumplings grow up and stay in melons. This can't be saved. If you don't, you can't grow a cucumber. In addition, the next year to stay on the roots of 2 to 3 leaves to stay again, or not grow up. Second: While taking advantage of the sunny days, plant activators can be used to add multiple leaf foliar sprays to increase plant resistance, supplement nutrients, and increase photosynthetic efficiency, thereby regulating melon-climbing symptoms. Thirdly, flushing and applying organic compound acid fertilizers when watering can effectively promote root and seedling growth, balance soil acidity and alkalinity, alleviate salinization, increase soil permeability, preserve water and fertilizer, and create a good soil environment for the root system. This will be able to alleviate the melon top of the ground part faster. The root is equivalent to the person's mouth, the soil is equivalent to the person's meal, has a good mouth rice, naturally grow strong! The same is true of plants. In this way, from top to bottom, from the management to the use of drugs, the causes of symptoms can be solved one by one, and the problem of melon topping can be solved. In addition, in the next year, replanting must pay attention to the use of organic compound acid fertilizers twice when planting, and once when planting water and easing seedlings. Choosing the melon in advance, spraying the plant activator on the foliar to increase the resistance, can effectively avoid the melon topping situation!
