Cucumber is one of the main vegetables in summer in China. It is widely cultivated all over China, and is cultivated in greenhouses or plastic greenhouses in many areas; it is now widely cultivated in temperate and tropical regions. So, how to plant cucumber with high yield? How to plant potted plants? What are the nutritional values?

How to plant cucumber with high yield?

1. Spreading plant ash: from the seedlings, plant ash is scattered on the roots or leaves of cucumbers, once every 10 days or so, for a total of 4 or 5 times, which can not only prevent diseases and insect pests, but also increase yield.

two。 Smoking method: filling the greenhouse with light smoke when the cucumber seedlings have 2 or 4 true leaves can increase the female flowers by 15% and increase the yield of cucumbers by about 10%.

3. Artificial castration: when the cucumber male flower is just formed, set aside 5% or 10% of the male flower, remove the excess, and pick it every 5 days.

4. Multi-vine hanging melon: to make full use of the side vine sitting melon, pick the heart of the weak side vine after sitting on the melon, and arrange and utilize the vigorous side vine to increase the melon population and increase the yield.

5. Add gas fertilizer: put dry ice or several buckets of stable manure in the greenhouse to increase the concentration of carbon dioxide through fermentation, the yield of cucumber can be increased by 30%.

6. Foliar fertilizer spraying: 0.2% borax + Zhuangguatiling is sprayed at the 7-leaf stage to increase the coarse melon stalk, strengthen the directional transport of nutrients, promote the rapid development of the melon body, do not fall flowers in the growth cycle, do not drop melons, and improve the melon setting rate. Spraying 0.3% potassium dihydrogen phosphate when a large number of melons are sprayed can increase the yield of cucumbers by about 20%.

How to plant cucumbers in pots?

1. Soil selection

Select partial clayey sandy loam or horticultural soil with pH between 6.0 and 7.5, rich in organic matter, good drainage and irrigation, water and fertilizer conservation.

Then soak in warm water for about 30 ℃ for 4-6 hours, scrub clean, drain, moisturize and germinate in a 28-30 ℃ incubator or warm place, and begin to germinate for 20 hours. In the early spring, the seedlings were raised in a small arch shed and planted in a seedling cup or seedling bed. The seedlings were planted at the age of 15-20 days (2 true leaves) and carried out in the evening on a sunny day. Pay attention to protect the root system, drench the seedlings with water before raising the seedlings, and plant them with soil in order to prevent root injury.

3. Build a frame to draw vines and pruning

General tendrils appear when the bamboo frame to lead the vine, build a "herringbone frame". The introduction of the vine begins after the tendril appears, and it is introduced every 3-4 days, so that the plant is evenly distributed and carried out in the evening on a sunny day. Whether the cucumber is pruned depends on the variety, the main vine generally does not need pruning; if the main and lateral vines bear fruit or lateral vines bear fruit, it is necessary to remove the top and pruning, generally all the lateral vines below 8 nodes are cut off, the lateral branches above 9 nodes are peeled after 3 nodes, and the main vines are peeled at about 30 nodes.
