In some greenhouses, the plants grow robustly after colonization, but after the melons grow, the stalks slowly become thinner. After the vines are falling, they are found to have a greater difference in the thickness of the vines between the vines and the vines. This is what cucumber farmers said. Waist phenomenon. How is this caused?
First, the thinning of cucumber stems, the most direct reason is to sit too much melon, affecting the growth of stem vines. Second, in the case of plants sitting in many melons, the management of fertilizers and water in vegetable farmers, especially fertilizers, has problems. It is more likely to cause fine stems and yellow leaves. Third, the sudden drop in temperature or the occurrence of cloudy days has led to a further increase in the phenomenon of "column waist".
Since the cause has been found, it can be treated symptomatically. First of all, we should reduce the number of melons on the plants and promote the recovery of plant growth; followed by strengthening the management of fertilizers and waters, and strengthening the management of fertilizers and waters, pay attention to three aspects:
First, pay attention to weather changes. Topdressing watering should be carried out in sunny weather. If it is even cloudy, even if the cucumber plants are slightly dehydrated or deferred, they should be delayed until the weather turns good.
Second, pay attention to soil moisture. Under normal circumstances, if it is not very arid, watering should be controlled as much as possible. The surface is dry, wet, soil is not agglomerated, and there is no waste. When the soil surface has small cracks, pour small water and apply it with water and fertilizer.
Third, pay attention to the rational growth of fertilizer according to cucumber growth. In general, the cucumber seedlings should control the watering in the period of seedlings so that the seedlings can be filled with topdressing water until the early flowering stage. The result should be based on the condition of the seedlings in time to carry out the top dressing and watering, with water, fertilizer and water.
