In fact, many growers will see the growth from the growth point of cucumbers, which are based on years of planting experience. The top of the cucumber plant is the growth point. The stretch is normal, bud-like from the side, and surrounded by two young leaves. When the environmental conditions deteriorate, it will cause abnormal changes in the shape of the growth point and other parts of the plant. Symptoms of growth point abnormalities caused by different causes are slightly different.
In the reproductive period of cucumber, the observation of the growth point morphology is strengthened. After the abnormality is found, in order to avoid further deterioration of the abnormal symptoms, it is necessary to carefully analyze the cause and take measures to promote the normal growth of the plant.
1. The growth point is fist-like
If the leaflets, tendrils, and female flowers at the growth point are tightened together, the temperature is low and the water content is low. If the growth point is too loose, it means the temperature is high and the water is too much.
2, the growth point is flower-like
If the growth point is scattered, the flower buds are convex and flowering, indicating that the night temperature and ground temperature are low, the fertilizer is insufficient, or it is endangered by pests and diseases.
3, the growth point is a tortoise
If the growth point is constricted, the root system is particularly weak or severely damaged.
4, the growth point at the flower buds buried
If the growth and development of flower buds are inhibited and concealed, it indicates excessive fertilization.
5, the growth point stops growing
If the growth point stops growing, the old leaves have white spots locally, and then brown and die, indicating that the night temperature is around 5 °C for a long time.
6, the growth point becomes smaller
If the growth point becomes smaller, the top of the small melon is above the growth point, the tendrils are curved, and the petals are small and pale, indicating lack of water.
7. Growth point cohesion
If the growth point is cohesive, the leaves are wilting, the leaf edge is rolled down, the texture becomes brittle, and there are white spots on the leaves, indicating high temperature and lack of water.
8, the growth point becomes smaller and shrinking
If the lower leaves of the plant are basically normal, but the upper leaves become smaller and the stems become thinner, the first piece of the upper part of the expanded leaf is bent forward, the growth point becomes smaller and atrophy, and the position of the melon is moved up or down, indicating that the plant growth potential is weak. .
9. The plant grows slowly after colonization and shrinks at the growth point.
If the plant grows slowly or not long after planting, the leaves are small and small, the growth point shrinks, and the growth point disappears, indicating that the planting is too deep or improperly watered, such as watering too late or too early, or pouring Insufficient water, or low water temperature and large water volume.
10, the growth point shrinks and becomes smaller
After planting, the leaves of the plant were small, the position of the melon was moved twice, the atrophy at the growth point became smaller, and the top of the flower was topped, indicating that the concentration of nitrogen and phosphorus in the soil was too large and lacked water, or the plant was malnourished.
11, the top of the growth point is dead
If the growth point and the top of the side branch die, the surface of the young leaf will die if it is dead, indicating that it may be boron-deficient.
12. The growth point disappears at the growth point
If the growth point of the growth site disappears, it may be caused by low temperature freezing, or the plant is extremely lack of nutrition, or end damage, or disease. If you take the roots of the cucumbers too late, it will easily lead to the disappearance of growth points.
Basically, these are the techniques for cucumber planting. You can also become a master of cucumber planting!
