Planting technology of cucumber on balcony

Cucumber is a kind of vegetable that many people like. It can not only make delicious food, but also has many cosmetic effects. Many friends who have balconies at home like to grow plants or vegetables on them, and the popular cucumber is the first choice for everyone to grow vegetables on the balcony, so what are the techniques and precautions for growing cucumbers on the balcony? Let's learn about it next.

Sowing time

It is generally carried out in early spring from January to March, and of course it can also be sown in summer and autumn from June to August. If sowing in spring, soaking seeds to promote germination is used to raise seedlings or plastic film covering direct seeding, while sowing seeds in summer and autumn can choose two methods: seed soaking direct seeding or dry seed direct seeding. The method of dry seed direct seeding can generally emerge seedlings in 3-4 days, and the time of seed soaking and budding is faster. When the cucumber sprouts 1-2 true leaves, it can be transplanted and planted.

Container selection

Can be flowerpots, wooden pots, professional cultivation boxes, styrofoam boxes, etc., the most important point is to drain air, and the depth of the plough layer is about 40 cm. If you cultivate soil, it is best to choose fertile, loose, well-drained soil, which is more conducive to its growth.

Seed soaking treatment

After selecting the container, the most important thing is to soak the seeds before planting. Soak the seeds in warm water of 55 ℃ for 20 minutes to keep them at a constant temperature, and keep stirring continuously during the soaking process, waiting for the water temperature to drop to room temperature, and then soaking for 6-8 hours. After that, the seeds were fished out, wrapped in wet gauze and germinated under the condition of 25-28 ℃. When half of the seeds were gradually exposed, they could be sown.

Seed on demand

Soak the soaked seeds evenly on top of the fine culture soil, and then cover it with a layer of thin soil about 1 cm thick. After sowing, it should be irrigated and planted once to keep heat and moisture, so as to slow down the seedlings. Spring cucumber seedling stage to control moisture, growing period to always keep the soil moist, flowering stage to control water, the result period of water demand, generally two to three days need to be watered once.

Apply sufficient base fertilizer

Applying enough basal fertilizer can ensure the better growth of cucumber. Sufficient base fertilizer is needed in planting, mainly rotten organic fertilizer, and fertilization should be combined with watering in the fruit period, and compound fertilizer can be applied every 5-7 days. Cucumber root is weak in absorbency and sensitive to high concentration fertilizer. It is appropriate to apply thin fertilizer frequently, once every 6-8 days, and to cultivate soil and fertilizer after the first batch of melons are harvested. Attention should be paid to phosphorus and potassium fertilizer to avoid steep growth and early senescence.

Set up a frame to draw a vine

A herringbone should be built to draw the vine when the cucumber tendrils appear. Insert a bamboo pole on the outside of the seedling, corresponding to each seedling. The two rows at the top of the bamboo pole are tied together. When the melon vine can not grow upright, you should tie the vine in time, and then tie it every 3-4 leaves. The binding rope is in the shape of "8" with the pole and vine, which can prevent the vine from rubbing or slipping. The binding vine should not be too tight, so it is appropriate to insert it into the index finger. Each binding vine to make the top of the melon vine fixed at the same height, easy to manage, and preferably in the afternoon, not easy to break the vine and leaves.

Hit the top and pick the heart

When the cucumber main vine climbs to the top of the rack, it is necessary to pick the heart in time, mostly when there are 30 to 35 leaves, picking the heart can promote the growth of melon. The heart-picking should be determined according to the characteristics of the variety. Most of the varieties that are easy to pick the heart are picked one month before pulling the seedlings, but the yield is low if the heart is picked too early, and the role of the melon can not be brought into full play if the heart is picked too late. Picking hearts, pinching tendrils and beating old leaves are all essential. only by doing a good job can we ensure the normal growth, flowering and fruit of cucumbers, and also control diseases and insect pests.

Timely harvest

Cucumber can be harvested about 10 days after the first serving, only about 45 days from sowing to planting, about 30 days from planting to root melon, and the harvest time is 1-2 months. However, in the process of planting cucumber, we should pay attention to keep the growth temperature of 20-28 ℃, if it is more than 30 ℃, it will grow badly, and if it is less than 10 ℃, it will stop growing, so we must control the temperature. The sunshade net should be covered before emergence in the hot summer.
