What are the precautions for growing loofah in summer
As summer gradually arrives, the harvest time for loofah also comes, and loofah gradually appears on the market. Loofah is a gourd vegetable with very high nutritional value and has a very large market demand in China. However, in the high-temperature and high-humidity environment of summer, it is very easy for loofah to develop various problems. So what precautions are there for growing loofah in summer? Below, the editor gives you a brief introduction. Let's take a look!
1. Water and fertilizer management
When growing loofah in summer, because the temperature is relatively high, fertilizer and water management must be done well during planting. During the loofah seedling stage, apply manure water about 3 times. At the early flowering stage, focus on fertilizing, applying about 100 jin of compound fertilizer per mu. After entering the harvest period, topdress once every two harvests, mainly with compound fertilizer, urea and potassium fertilizer. During the seedling stage, watering should not be excessive, otherwise it will have a certain impact on the roots. After entering the vine-growing and flowering stage, the amount of watering should be appropriately increased, and watering at noon on sunny days is not suitable. During the harvest period, not only should watering be appropriate, but a water layer of about 15 cm should also be kept in the ditch. Finally, in rainy weather, attention should be paid to drainage work.
2. Trellising and vine guiding
Loofah is a vine-growing vegetable, so when planting, we must also do the trellising work well. When the loofah vines grow to about 30 cm, insert a trellis into the soil. After inserting the trellis, carry out vine nestling and pressing work on the loofah vines, and when female flowers appear, guide the vines and distribute the vines evenly on the trellis. If the loofah appears bent, then hanging the fruit should also be carried out, tying the fruit stalk with a string, tying a stone below the string, and pulling the fruit to the branch. Hanging the fruit is generally carried out about 3 days after harvest.
3. Temperature and light
Although loofah is a summer crop, the temperature should not be too high. During the growth period of loofah, the temperature should be controlled at around 30 degrees, and the temperature at night should also be kept suitable. If the temperature is too high, then it should be cooled in time. Of course, the temperature should not be too low either. We should pay attention to observing weather changes so as to handle them in time and ensure that loofah growth has a suitable temperature. Then note that loofah must not be exposed to direct sunlight during growth. Therefore, in summer we should also pay attention to sun protection measures to ensure normal growth of loofah.
4. Pest and disease control
Although the temperature in summer is high, it is also easy for many pests and diseases to appear, such as viral diseases, leafminer flies, aphids, etc. Therefore, in summer we should also focus on doing a good job in pest and disease control. Everyone should often check the growth of loofah so as to discover disease symptoms in time and handle them. Moreover, when planting, we should pay attention to regular disinfection, eliminate the base number of pathogens in the field, and reduce the incidence of pests and diseases.
The above is a brief introduction to the precautions for growing loofah in summer. Growing loofah in summer requires us to pay attention to many things, and it is also the focus of our management, so everyone must pay more attention. That is all for today's introduction.
