The main cause Gherkin "pinched waist" There are three reasons: 1 small cucumber vine thinning, the most direct reason is Zuogua too much, that is, my friends often say that farmers LaGuardia too, affect the stem vine growth. 2. In the case of plants Zuogua more, farmers in particular, fertilizer top dressing fertilizer and water management problems are more likely to cause thinning vine leaves yellowing. 3. The temperature suddenly dropped and cloudy day lead to "loins" phenomenon further. Since the reason is found, it can be "symptomatic and treatment," the. First, it should reduce the number of plants on the left melons, promote plant growth recovery. Second is to strengthen the management of fertilizer, especially fertilizer. Here, to remind the farmers friend is to strengthen the fertilizer and water management should pay attention to three aspects: 1. Note the changes in the weather. Dressing in fine weather watering should be, if rainy days, cucumber or even a little water until Tuofei should try then when the weather turns for the better, or not conducive to plant growth and development. 2. attention to soil humidity. 3. Note the rational fertilization based on small cucumber growing. Generally small cucumber planting Huanmiao control of water, Huanmiao to combine early flowering small water pouring dressing, results of peak fertilizer to timely watering seedlings condition according to the water with fertilizer, fertilizer Qi attack. In the choice of fertilizer cucumbers, instant fertilizer can not simply be ascribed potassium type, which is a common misunderstanding of many farmers, always feel the results after the flushes hyperkalaemic, in fact, plant growth and for melon vine Coordination should also be, that type of water-soluble potassium fertilizer and balanced water-soluble fertilizer alternately flushes largest cucumber sales base, such as adding and Guo Sheng and so on. After the temperature was lowered largest cucumber supply base, but also to add biological fertilizer like manure, conservation roots, only a strong root system, in order to better absorb nutrients supply plant and fruit growth enlargement.
