There are three main reasons for the cucumber's "waist": the most direct reason is that there are too many melons, which affect the growth of stems. Fertilizer management, especially for fertilizers, is more likely to cause stems to become thinner and leaves to turn yellow. The sudden drop in temperature and the cloudy day have further aggravated the phenomenon of “waistingâ€. 1. Weather changes. Topdressing and watering should be carried out in fine weather. If it is rainy or rainy day, even if the cucumber is slightly dehydrated or de-fertilized, it should be extended until the weather turns better. Otherwise, it is not conducive to plant growth and development. 2. Soil moisture. Because of its specific environment, cucumber has strict requirements for watering. Under normal circumstances, if it is not very dry, it should be controlled as much as possible. It is better to see the wet surface, the soil is not agglomerated, and there is no waste. When the soil surface has small cracks, water is poured, and combined with watering, the fertilizer is applied. 3. Rational fertilization according to the growth trend. Generally, the cucumber is planted in the slow seedling stage to control the watering, and the slow seedling to the early flowering stage is combined with the top dressing and pouring the small water. The result is timely and topdressing according to the seedling condition, and the water is fed with fertilizer and fertilizer. The application of high-potassium products cannot be unilaterally applied because the growth of the stems and the melons should be coordinated at the same time. The high-potassium water-soluble fertilizers and the balanced water-soluble fertilizers should be alternately applied, such as energy and fruit. After the temperature is lowered, it is necessary to supplement the roots of the bio-fertilizer to maintain the root system. Only when the root system is strong, can the nutrients be better absorbed and the plants and fruits grow and expand.
