When is the cucumber sowed? Cucumber cultivation method and planting time
Cucumber is crisp and refreshing. It can be eaten raw or cooked. It is a vegetable variety that many people love. Today, let's talk about cucumbers from land preparation to harvesting. How to cultivate high yields?
1. Points to note
In the flowering stage of cucumber, you can put a little sugar water on the petals and leaves, which can help attract bees to pollinate honey and increase cucumber yield.
2. Selection
It is recommended to use Bonai No. 3 and Jinyou No. 10, which are some varieties with good commercial properties and high yield.
3. Site preparation
Cucumber planting soil requires a pH of 5.7-7.2, which is loose and fertile and rich in organic matter.
4. Seed soaking
Soak the seeds in warm water at 55 degrees Celsius for 10 to 15 minutes, and keep stirring. After the water temperature drops to about 30 degrees, soak for another 3 to 4 hours. Finally, wash the seeds repeatedly, and then dry them. Promote germination.
5. Seedbed preparation
It is recommended to use vegetable garden soil or large field soil that has not cultivated melon vegetables within three to five years, and then mix with high-quality decomposed organic fertilizer in a ratio of 3 to 1, and add 3 kg of three-element compound fertilizer per cubic meter.
6. Sowing and seedlings
The sowing date of spring cucumber is determined according to the planting period. The appropriate calendar for colonization is 40-50 days old, and the physiological seedling age is four leaves and one heart. If the calculation is based on the calendar age, the seeding will be carried out 40 to 50 days before the planting. The length of physiological seedling age is related to the method of seedling raising. It takes 50 to 55 days to grow seedlings in Yangshuo or solar greenhouses; 45 to 50 days in warming greenhouses; and 45 days in greenhouses using electric heating lines. Therefore, the seedling methods are different and the sowing time is different. Practice has proved that rapid seedlings not only save time, but also produce fast and strong seedlings, and high yields in the early stage. Where possible, try to use rapid seedlings.
7. Temperature management
During sowing to unearthed daytime temperature should be controlled at 28 ° C ~ 32 ° C, night 10 ° C ~ 18 ° C; unearthed to break the heart temperature should be controlled at 25 ° C ~ 30 ° C, night 16 ° C ~ 18 ° C; broken heart to colonize day temperature The control is between 20 ° C and 25 ° C and 12 ° C to 16 ° C during the night.
8. Water management
The seedling stage should be properly controlled, see dry and wet, watering should be poured.
9. Refining
7 to 10 days before planting, water should be controlled, and ventilation should be increased to carry out low-temperature refining. The daytime temperature is between 18 ° C and 20 ° C and the night temperature is between 8 ° C and 10 ° C. When the seedlings reach a plant height of 15 cm, 3 leaves and 1 heart, the seedling age can be fixed when it is about 35 days old.
10. Watering, cultivating loose soil
4 to 5 days after planting, when the heart leaves begin to grow. When the underground minister has a large number of new roots, pour a slow seedling water. After watering, until the root melon is sitting, generally do not water, cultivating loose soil. The first cultivating requirement is deep, transparent, fine, about 7 cm deep, and the seedlings should be thoroughly permeated, but the roots should not be damaged. The purpose of cultivating is to loosen the soil, increase the ground temperature, and promote root growth. Control stem and leaf growth, seedlings. When the first melon of most plants (called root melon) sits (the melon grows to about 12 cm, it is not easy to turn the melon when it is called melon). The result is a seedling, and the topping water is started. This water should be larger.
When the local skin is not sticky, carry out the second cultivating, shallow hoeing, combined with cultivating to remove weeds. After the head water is poured, it can no longer be short of water. After watering, it depends on the sky. Look at it and be flexible. During the harvest period of the root melon, the day is not too hot and the evaporation is small. The scorpion is not too high, the watering should not be too diligent, and the amount of water should not be too large. Generally, water is poured every 6 to 7 days. In order to harvest the waist claws to harvest the top melon is the melon period, the temperature is already high, the evaporation is large, the stems and leaves are flourishing, and the growth is determined. There are many times of cucumbers in the life of cucumber. Generally, water is poured every 3 to 4 days, and the amount of water should not be too large. It is recommended that small water should be poured and water should not be poured.
After harvesting the top melon, the melon is gradually aging, the growth of stems and leaves is small, and it is in the rainy season. It is necessary to control the number of watering. Do not pour a water every 5 to 6 days without rain, so that the land is not dry. In the watering time, the early stage of the results is best carried out in the morning, the harvesting period and the late stage, the watering in the evening, can reduce the ground temperature. Cucumbers are afraid of sputum, and should pay attention to drainage after the rain to avoid water accumulation in the sputum.
11. Inserting, tying
In order to prevent wind smashing seedlings, after planting, we strive to insert the shelves on the same day. Cucumbers are mostly made of herringbone flower stands, and a seedling is inserted into a bamboo raft, which is inserted outside the seedlings. The two ends of the bamboo pole are tied together. When the vine grows tall and can't grow upright, it should be tied in time. After every 3~4 leaves, the tie rope and the frame and vine are “8†shaped, which can prevent the vine and the frame from rubbing or sliding. It should not be too tightly tied, and the gap should be inserted into the index finger. Each time the vines are tied to the same height of the vines, it is easy to manage. The vines are best carried out in the afternoon, and it is not easy to damage the vines and leaves.
12. Harvest
Generally, the melons are collected about 25 to 30 days after the planting, and the harvesting period is about 40 to 60 days. The average mu yield is 3,500 to 4,500 kg. The melon should be harvested at the right time, when the top of the melon strip is rounded from the tip. At this time, the melons have grown up fully, but they are not old, and they are harvested at an appropriate time.
Vegetable growers who want to learn cucumber planting technology can look at it more, and can also recommend forwarding to other farmers around. Of course, Hui Nongwang Xiaobian also hopes that every farmer can learn the knowledge he wants to know!
Fruit juice drinks is a beverage made of fruit juice products obtained by physical methods such as pressing, centrifugation and extraction. Fruit juice retains most of the nutrients in the fruit, such as vitamins, minerals, sugar and pectin in dietary fiber. Often drinking fruit juice can help digestion, moisten the intestines and supplement the lack of nutrients in the diet.
There are two kinds of fruit juice: pure fruit juice and compound fruit juice. As far as pure fruit juice is concerned, it can be divided into two types: one is to directly use the original juice, and the other is to dehydrate the freshly squeezed fruit juice first, and then add water to reduce it into concentrated fruit juice. Most pure fruit juices are concentrated. AGOLYN offers various flavors of honey tea, such as honey Citron tea etc.
