There are three main reasons for the thinning of cucumber stems:
1. Cucumber stems become thin, the most direct reason is to sit too many melons, which is often said La Guagua friends too much, affecting the growth of stems.
2. In the case of plants sitting on many melons, the management of fertilizers and water in vegetable farmers, especially fertilizers, is more likely to cause thinning of stems and yellowing of leaves.
3. The sudden drop in temperature and cloudy days have further aggravated the phenomenon of "squeeze".
Precaution:
First of all, the number of melons on the plants should be reduced to promote the recovery of plant growth. The second is to strengthen fertilizer and water management, especially top dressing. Here, we must remind the vegetable farmers that the management of fertilizer and water should pay attention to three aspects:
1. Pay attention to 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. Pay attention to the dryness of the soil. 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 much as possible; seeing the surface dry and wet, the soil not agglomerating, and non-flooding waste is good. When the soil surface has small cracks, pour small water and apply it with water and fertilizer.
3. Pay attention to reasonable fertilization according to the growth of cucumber. General cucumber planting control seedling period of watering, Huanmiao to early flowering period combined with top-dressing water, the result of flood season according to seedling status in time to top-dressing water to water with fertilizer, fertilizer and water Qi attack.
In the selection of fertilizers, that is, the fertilization materials can not be single-high potassium type, which is the common misconception of many vegetable farmers, the total feeling of the results should be flushing high potassium type, in fact, plant stem growth and feeding should be At the same time, the coordination is carried out, that is, high-potassium-type water-soluble fertilizers and balanced water-soluble fertilizers are alternately applied, such as energizing and fruiting. After the temperature is lowered, it is necessary to supplement the fertilizer of the biological bacteria fertilizer and maintain the root system. Only when the root system is strong can the nutrients supply plants and the fruit growth be enlarged.
