1. The most direct reason is to sit too much and affect the growth of stems.
2. The management of fertilizer and water, especially the problem of fertilizer application, is more likely to result in thinning of stems and yellowing of leaves.
3. The sudden drop in temperature and cloudy days have further aggravated the phenomenon of "squeeze".
When the cause is found, treat it symptomatically. First, reduce the number of melons on the plants and promote the restoration of plant growth. The second is to strengthen fertilizer and water management, especially top dressing.
Remind vegetable farmers that strengthening water and fertilizer management should pay attention to:
1. The weather changes. Topdressing watering should be carried out in sunny weather. If it is rainy, gherkins should be delayed as long as the weather turns to be better, even if there is a slight water shortage or defertilization, otherwise it is not conducive to plant growth and development.
2. Soil moisture. Gherkin has strict requirements for watering due to its specific environment. Under normal circumstances, if it is not very arid, watering should be controlled as far as possible, and it is better to see dry and wet soil on the surface, no agglomeration of soil, and no waste. When the soil surface has small cracks, pour small water and apply it with water and fertilizer.
3. According to the growing trend of reasonable fertilization. General cucumber planting control seedling period watering, easing the seedlings to the early flowering period combined with top-dressing pouring water, the results of the flood season according to seedling status in a timely manner topdressing water, with water, fertilizer, water, flood attack. The fertilization material can not be single-selected high-potassium products, because the plant stem growth and supply melon should be coordinated at the same time, high-potassium water-soluble fertilizer and balanced water-soluble fertilizer to alternate flushing, such as energy, fruit Sheng and so on. After the temperature is lowered, it is necessary to supplement the roots of the biofungus, and only the roots are strong enough to better absorb nutrient supply and fruit growth.
