Cucumber, often called water melon, is favored by consumers because it is juicy and refreshing, cool and thirst-quenching. However, did you know that cucumbers can't be watered indiscriminately in certain situations?If not careful, this can have a negative effect on the growth of cucumbers and even lead to the death of the plant. Next, let's have a ** after all.
When the ground temperature is too low and the humidity is too high, cucumbers should not be watered. Out-of-season cucumbers, whether in the seedling or growing stages, have a high demand for the right growing temperature in greenhouses or greenhouses. When the soil temperature is too low, the water absorption capacity of the cucumber root system will be greatly weakened, and even cause lesions. Therefore, in this case, we need to try to control the amount of watering so as not to bring irreparable damage to the growth of cucumbers.
It is also not advisable to water cucumber after planting and before the root melon sits. When cucumbers are planted, we need to give enough water to facilitate close contact between cucumber roots and the soil to promote nutrient absorption. However, in the following period, the plant needs to adapt to the new environment and the root system is firmly established, and it is not advisable to overwater at this time, so as not to form stagnant water and cause a lack of oxygen to the root system. Therefore, we should pay attention to the growth process of cucumbers and water them reasonably according to the water needs of the plants.
In addition, during the growth of cucumbers, when downy mildew and other diseases occur, they should not be watered at will. Downy mildew, an unstoppable disease, is widespread in cucumber-producing areas. Its destructive power can be described as devastating and ubiquitous. This hidden danger exists whenever and wherever in the field where cucumbers are grown. It mainly causes damage to the leaves of cucumbers, causing the leaves to dry up and eventually killing the entire plant. Therefore, when we find that cucumbers are attacked by diseases such as downy mildew, the first task should be to take appropriate control measures instead of blindly watering them.
After understanding the situation that cucumbers cannot be watered at will, let's take a look at the water demand rules and watering methods of cucumbers. Cucumbers have different water requirements at different stages of growth. Especially during the peak of melon production, the water demand of cucumbers reaches its peak. In general, cucumbers need to be watered every 3 to 5 days to keep the soil moist. In addition, the watering time should also be paid attention to the choice, especially in the high temperature season, it is best to choose the morning or evening watering to avoid the water evaporating too quickly, affecting the normal growth of cucumbers.
In order to better enlighten you, we will further explain the water demand rules and watering methods of cucumbers through some specific cases.
Case 1: Xiao Ming is a farmer who loves planting. He grows a batch of out-of-season cucumbers in the greenhouse. However, due to not noticing the low ground temperature in the greenhouse, Xiao Ming watered the cucumbers at an inappropriate time, which seriously affected the growth of the cucumbers and greatly reduced the yield.
Case 2: Little Red has been cultivating cucumbers for many years and has rich experience. She found that cucumbers with the right amount of watering grew particularly well and had strong roots, after the cucumber was planted and the seedlings were planted slowly and before the roots were sitting. The soil that has been kept moist has led to underdeveloped root systems and unsatisfactory quality of cucumbers.
Case 3: Lao Wang is a professional cucumber household. One day, he noticed that his cucumber leaves had white spots of downy mildew. Lao Wang immediately took appropriate prevention and control measures, such as spraying pesticides in a timely manner. As for watering, he noticed that after the cucumber is attacked by the disease, it is not advisable to water it at will, so as not to aggravate the disease.
After the analysis of the above cases, we deeply understand the law of water demand of cucumbers and the importance of watering methods. Only by reasonably controlling the amount of watering and watering at the right time according to the water demand of the plant can we effectively promote the growth and development of cucumbers and improve the yield and quality.
