How long does it take from flowering to maturity of cucumbers? How many days is the growth cycle? How to manage after flowering? No, what about the result?
Cucumber is also known as cucumber, thorn melon, king melon, Qin melon, cucumber, Tang melon, hanging melon, flower and fruit period in summer. It is widely cultivated all over China. So how long does it take from flowering to maturity of cucumbers? How many days is the growth cycle? How to manage after flowering? No, what about the result? According to the data of Cucurbitaceae, the growth cycle of cucumber is 90-120 days under natural conditions. Its growth and development generally go through four stages: germination stage, seedling stage, early flowering stage and fruiting stage.
How long does it take from flowering to maturity of cucumbers?
1. The female flower of cucumber itself is composed of small fruit and flower. At first, the small fruit is seen, then it blossoms, and the flower falls and the fruit grows. According to the season, it can be harvested about a week after flowering in summer and about 15 days in spring and autumn.
2. The handle of cucumber is dark green, the peel is shiny, the spines turn white on the melon, and the melon can be harvested with light green stripes on the top (proper management, generally 7-12 days after flowering). In order to be fresh and tender, reduce nutrient consumption and increase the number of melon strips per plant, tender melon strips, especially root melons, should be harvested in time to prevent melon seedlings from falling.
How to manage cucumber after flowering?
The main results are as follows: 1. Cucumber flowers usually bloom from 05:30 to 6 o'clock and bloom for 1-1.5 hours. the life span of cucumber flowers can be delayed until the afternoon of the same day, and the male flowers will fall off the next day, but they can bloom normally in low temperature and rainy weather. When the Corolla is fully unfolded, that is, when the anther opens. On the other hand, the pollen has the ability to germinate in the afternoon of the day before flowering, but the germination ability is the highest when the medicine is opened. In the natural state, the life span of pollen rapidly loses its vitality 4-5 hours after the drug is prescribed, and the life span is short when the temperature is high.
2. The flowering and flowering of cucumber are closely related to temperature, and the higher the temperature is, the more it can be promoted in a certain range. Generally, it begins to blossom at 15 ℃ and begins to open at about 17 ℃. The optimum temperature for them is 18-21 ℃, and the flowering stops below 12.8 ℃. The temperature limit of pollen germination is between 10 and 35 ℃, and the optimum temperature is 17 to 25 ℃. Cucumber can reach 2~3mm in pollen tube 4-5 hours after pollination. Cucumbers are basically monoecious but different flowers, and occasionally appear bisexual flowers.
What if the cucumber blossoms and doesn't bear fruit?
The reason why cucumber blossoms and does not bear fruit:
1. There are many melons in production. All the melons that can sit are left behind, and the extra female flowers are not removed.
2. Improper fertilization. Excessive use of compound fertilizer makes the concentration of soil solution too high, weakens the absorptive capacity of roots, and affects the normal growth of plants.
3. Overdose. In the prevention and control of diseases and insect pests, some vegetable farmers only pay attention to chemical control, but ignore agricultural measures, the interval between the use of drugs is short, the concentration seriously exceeds the standard, resulting in drug damage, coupled with the random application of hormone pesticides, resulting in physiological imbalance of cucumber plants. so that the growth point of cucumber can not grow normally.
4. Improper watering. Watering did not pay attention to the weather conditions, and did not analyze the advantages and disadvantages of watering according to the law of plant growth. If the unfavorable weather, such as continuous overcast days, low temperature and strong cold current, is encountered after watering, the ground temperature is lower than 12 ℃, and the soil relative humidity is higher than 85%, resulting in cucumber retting, which inhibits the root growth and has a greater impact on the upper growth.
5. The harvest is not timely. Due to the unstable price of melons, sometimes in order to wait for the high price, the already grown melons are left on the seedlings, resulting in "falling seedlings". As a result, the balance between vegetative growth and reproductive growth of the plant was broken, resulting in excessive consumption of organic nutrients in the plant.
Measures for cucumber flowering and non-fruiting:
1. Fall the vine properly. Cucumber should not fall too low at one time when falling from the vine, which is not conducive to the normal growth of cucumber. After falling the vine, the cucumber plant is maintained at a height of about 1.5 meters, ensuring that there are more than 15 functional leaves on the plant in order to ensure normal photosynthesis and maintain normal growth.
2. Pay attention to thinning flowers and fruits. For more melon plants, it is necessary to properly sparse melons, must not see melons to stay, otherwise it is easy to cause seedling suspension in the middle and later stages. The yellowing leaves at the bottom should be removed in time to reduce consumption.
3. Strengthen the management of light on continuous overcast days. When the cloudy day is close to noon, if the grass grass is opened for another 2 hours, it will not decrease the greenhouse temperature, but will increase by 2 ℃. After it suddenly clears up on a cloudy day, you can't suddenly uncover all the grass, but you should "uncover the flowers" so as not to cause "flashing seedlings".
4. Pay attention to fertilizer and water management. When the temperature is low and the light is weak, the watering times should not be too frequent. Generally, it can be watered once in about 20 days, not flooding. Also note that after watering, it is necessary to wait for the temperature in the shed to rise to more than 30 ℃ before releasing the air, and the tuyere should be from small to large, not too large at one time, resulting in the phenomenon of "flashing seedlings". Fertilizer is generally flushed with water, to be easily absorbed by cucumbers containing humic acid or amino acid fertilizer, one-time dosage should not be too much.
5. strengthen the prevention and control of diseases. Due to the untimely release, it is very easy to cause drug damage after administration in the shed, so the concentration should be strictly controlled when using drugs, and the mixture of three or five pesticides should not be mixed to reduce the occurrence of drug damage.
