Latest Summary of Precautions for Growing Cucumbers in Summer
Cucumber is a type of gourd vegetable that many people enjoy eating very much, and it has a very large planting area in our country. When growing cucumbers, we need to reasonably adjust cucumber management methods according to seasonal changes. Especially in summer, because of the high-temperature and high-humidity environment, there are many points that require our attention. So today the editor has brought you the precautions for growing cucumbers in summer. Let's take a look together!
1. Mulching with straw and tying vines
Summer temperatures are very high and can cause great harm to cucumber seedlings. Therefore, after entering summer, we should spread about 4 cm thick straw on the bed surface to prevent the soil temperature from getting too high, speed up water evaporation, and promote cucumber growth. Then, when the cucumber vines begin to run, use wooden strips and other items to set up trellises, keeping the height at about 150 cm, mainly in the shape of an inverted V. When the vines grow to about 35 cm, you can begin tying the vines. Then tie the vines about every 3 nodes to provide sufficient growing space for the cucumbers.
2. Water and fertilizer management
Summer is the peak growth period for cucumbers. At this time, cucumber growth speeds up and yield increases. Therefore, in summer, water and fertilizer work must be done well. During the entire growth period of cucumbers, topdressing should be done at least about 3 times. Control the amount of fertilizer and nutrient ratio according to soil fertility and the cucumber growth stage, generally focusing on ternary compound fertilizer. Then also appropriately spray foliar fertilizers such as potassium dihydrogen phosphate. In summer, also pay attention to controlling the amount of watering, keeping the soil moist is enough; do not water too much, to avoid root burn and root rot caused by water temperature being too high, which can trigger root diseases and reduce yield.
3. Pruning at the right time
Cucumbers have relatively strong growth and branching ability. So in summer we should often observe the growth of cucumbers and do a good job of pruning. When growing cucumbers, remove all lateral branches completely, and pinch off the tips within 1-2 leaves. If the number of stems exceeds the main stem, also pinch off the tips in time. Promote fruit formation on the lower branches and enhance growth ability. Then, before the cucumbers are lowered, remove poor leaves such as old, weak, diseased, and pest-damaged leaves from the lower part of the plant. Avoid consuming too many nutrients, improve field ventilation, reduce the spread of pathogens, and lower the incidence of pests and diseases.
4. Cultivation and weeding
Summer is also when weeds have the strongest growth ability. If weeds are not removed in time in summer, weed overgrowth will occur. This causes cucumbers to have their nutrients and water taken away, so weeds must be removed in time to ensure cucumber growth. However, also pay attention to controlling the amount of weeding; do not remove all of them, to avoid the soil temperature getting too high. Then also cultivate regularly to avoid soil compaction, which affects cucumber nutrient absorption and reduces yield. Moreover, proper cultivation can also achieve the effect of weeding.
The above is a brief introduction to the precautions for growing cucumbers in summer. In fact, these are also the basic management tasks we need to do well when growing cucumbers in summer, so everyone must pay more attention. That is all for today's introduction.
