Straight and curved cucumber is one of the important indicators to identify the quality of cucumber, which directly affects the economic benefits of cucumber cultivation. The main reasons for this are the lack of light, improper temperature and water management, and malnutrition. Prevention of cucumber bending: To ensure adequate lighting When planting in the greenhouse, due to poor lighting conditions, plant spacing must be sufficient to ensure sufficient light. But be careful not to pick too many leaves to ensure enough photosynthetic product.
Fertilizer and water management The cucumber enters the initial flowering stage, and the small melon has just begun to grow. At this time, it cannot be watered. At least, it cannot water a lot, and it cannot fertilize it. However, when the melon grows to 10 centimeters in length, some vegetable farmers do not dare to water the plants. They are afraid that the plants are long and they continue to control the water. This is very unscientific. At this point, it is the time when cucumber fruit grows rapidly and needs water and nutrients. If the supply of fertilizer and water is not timely, it will cause the cucumber to bend.
Once the razor blade has been processed, before and after the opening of the young flower, use the blade to make a shallow print on the back of the curved cucurbit, and then cross-cut 1-3 shallow prints, 0.5 cm deep and 2-5 cm long. This bend can be straightened, and the wound is almost invisible when it is sold.
The reins fall directly from a small tile or small brick or small stone that is 4 cm in length and 2 cm in width, and is made of fine hemp rope or fine plastic rope. When the cucumber grows to 10 centimeters in length, you can hunt small tiles or small bricks on the cucumber handle if you find the curved guava, so that with the growth of the cucumber, the small brick can straighten the curved guava.
Rollers must be removed and tendons must be removed in addition to the curved melons to prevent bending caused by physical obstacles such as tendrils. The vegetable farmers can also remove the curved guava before and after the female flowers without affecting the yield and benefits, which can promote the cultivation of the next melon market.
The yield of a single plant that controls the yield of a single cucumber cannot be too high. An excessively high yield per plant can increase the burden on the plant. In the early stages, excessive fruiting or picking is not timely, and the leaves age quickly, and it is easy to form a curved melon.
Strengthen management If the fertilizer is insufficient, the planting density is large, the light is less, the weeds are more, the supply of nutrients is not on, and the soil is dry, and the heads are easily bent. If the nutrient water is too much, the stems and leaves are too luxuriant, and the big heads are easily bent. . Therefore, reasonable cultivation measures should be taken, scientific fertilization, watering should be done (but each time the amount of watering should be less), the watering time in the high temperature period should not be too long, to avoid the soil is too dry, too wet, and actively control pests and diseases to promote The fruit grows smoothly.
The Fluorochemicals compound is a new field in modern organic chemistry. It has a special physical and chemical properties, so it is widely used in the earliest development of applied pesticides and rat poison. During World War II it was developed in some countries appliedas antimicrobial agents, there are more and more new research suggests that fluorochemical will play an increasingly more important role in the field of anticancer drugs. We started later in the field of fluorochemicals, but we have a strong sense of his enormous potential, and we are increasing investment to catch up. We will custom product which has potential market prospects from gram and kilogram-class through process optimization, enlarged to the size of ton. Currently we have developed more fluorochemical compounds in the benzoic acid range, the number of products have been more than 2017.
