If the cucumber is to be sold at a high price, it is very important to sell it. When many people choose cucumbers, the first thing is to look straight and then look fresh and not fresh. However, many growers have reported that this cucumber has been bent and planted, and it does not know what is going on, and it is even more difficult to know how to prevent it. Here, Hui Nong.com compiled the reasons for the bending of cucumber and the preventive measures. Let's learn together.
First, the reason for cucumber curved melon
1. When the growing cucumber hits the blade, the tendril or the hanging wire, it blocks the benton;
2. When the temperature of cucumber is too high or boron deficiency, the flower bud differentiation may be poor, the quality of the flower length is not good, and only the egg cells on the side of the ovary are fertilized, resulting in the imbalance of the whole melon development and the formation of the curved melon;
3. When we pick the leaves too heavy or leave too much fruit at one time, such as melons in the section, and there are pickable melons falling under the cucumbers, causing the curved melons;
4. When we use too much or single nitrogen fertilizer or chicken manure, pig cow dung, potassium fertilizer, phosphate fertilizer or continuous inferior fertilizer or some hormone fertilizers, soil acidification, salinization, insufficient nutrient supply, hormone poisoning , producing a large number of curved melons;
5, when the cucumber is over-watered after the drought is too large or watering is not timely, it is easy to cause curved melon and melon;
6, a sudden cloudy day suddenly clear, high temperature glare caused by insufficient supply of water, nutrients caused by curved melon;
7, pests and diseases caused by curved melons, melons, such as cucumber downy mildew, powdery mildew and some phytotoxicity, fertilizer damage caused by the loss of function leaves of cucumber, the nutrients produced by the plant is not enough to supply the expansion of cucumber, resulting in bent melon.
Second, how to prevent cucumber bends?
1, reasonable picking leaves
Reasonable leaf picking, retention of melon, cucumber and melon strips require large leaves to provide sufficient nutrients. Therefore, the vegetable farmers must master such a principle in the process of picking leaves: remove the bottom aging diseased leaves and leave more functional leaves.
In general, at least 13 leaves of cucumber leaves should be preserved to ensure plant growth and melon growth. At the same time, it is also necessary to avoid excessive melons at one time. The melon should be kept according to the growth of the plant and the growth of the leaves. Generally speaking, the principle of “one cucumber, three melons, three melons, large and medium-sized†can be used to keep the melon, that is, a melon in the flowering period, one Melon in the expansion period, a melon to be picked.
2, strengthen the shed temperature management
The temperature required for cucumber flower bud differentiation is: 25-30 °C during the day and 13-15 °C during the night, which is beneficial to the accumulation of nutrients in the cucumber, and significantly increases the number of female flowers and the quality of flower bud differentiation.
At this stage, if the temperature of the greenhouse is too low or too high, the flower bud differentiation of cucumber will be poor, which will seriously affect the quality and quality of the late melon. Therefore, we must properly control the temperature.
Sunny: timely ventilation and high temperature; rainy days: timely heat preservation and low temperature, improve the quality of flower bud differentiation.
3, balanced fertilization, reasonable watering
During the management of cucumber, avoid flooding with large water, and attack the fertilizer and water to avoid affecting the normal growth of the plant.
Usually watering is required, but each time the amount of water is small. In fertilization, it is necessary to use NPK fertilizer and microbial fertilizer, as well as multi-element mineral fertilizer and organic fertilizer to promote the growth of cucumber roots and supplement nutrients.
Third, how to treat cucumber curved melon?
The bent melon that has already occurred should be removed in time. It is also possible to drop a stone at the lower end of the curved melon, and use the weight of the object to sag and straighten the melon.
The above is the reason why the cucumber bends and the prevention and control measures are compiled by Huinong. We must do the above precautions when planting cucumber. If you find that the cucumber has been bent, don’t panic. Try the above method first. Maybe it will be back.
