With the improvement of living standards, more and more people have begun to pay attention to eating healthy, and green vegetables have become a must-have on our table. Among them, cucumber is loved by people as a nutritious vegetable. So, how to grow cucumbers and master their management techniques?Next, let's learn about cucumber planting methods and management techniques.
1. Preparation before planting
Soil selection: Choose fertile, loose, well-drained soil, preferably one that has not been planted with melon crops.
Seed selection: Choose suitable varieties according to local climatic conditions, and it is recommended to choose seeds that are disease-resistant, cold-tolerant, and have high yields.
Land preparation and fertilization: Before planting, the land is deeply cultivated, and foot fertilizer is applied, and 2000-3000 kg of rotted farmhouse fertilizer is generally applied per mu.
2. Planting method
Sowing time: Choose the appropriate sowing time according to the local climatic conditions, generally sowing in mid-to-late March to early April in spring, and sowing in mid-to-late July to early August in autumn.
Sowing method: planting by direct seeding or seedling transplanting. During the live broadcast, open the ditch according to the row spacing, the depth of the ditch is about 2-3 cm, the seeds are evenly sprinkled in the ditch, and the soil is covered and watered;When transplanting seedlings, first raise seedlings in a greenhouse or greenhouse, and then transplant them to the field when the seedlings grow to 3-4 true leaves.
Density and depth: The planting density of cucumbers is generally about 3000-4000 plants per mu. The sowing depth should be twice the size of the seed, and the soil should be gently compacted after covering.
3. Management technology
Watering: Cucumbers need to keep the soil moist during the growing period and water them in time according to the weather conditions. During the dry season, the frequency and amount of watering should be increased;In the rainy season, attention should be paid to drainage and flood prevention.
Fertilization: Cucumbers need sufficient nutrients during the growth process, and fertilizers such as nitrogen, phosphorus, and potassium should be applied during the growth period. The first top dressing is carried out when the cucumber grows 3-4 true leaves, and 5-10 kg of urea is applied per mu;The second top dressing is carried out when the cucumber begins to climb the vine, and 15-20 kg of compound fertilizer is applied per mu;The third top dressing is carried out when the cucumbers begin to set melons, and 10-15 kg of urea is applied per mu.
Scaffolding and pruning: When cucumber plants begin to climb the vine, scaffolds should be built and the vines should be brought up to promote the upward growth of the plants. At the same time, pruning and forking should be done appropriately as needed to reduce nutrient consumption and the occurrence of diseases.
Pest control: cucumbers are prone to pests and diseases during the growth process, such as downy mildew, powdery mildew, aphids, etc. The growth of plants should be checked regularly, and measures should be taken to prevent and control pests and diseases in time. Commonly used control methods include agricultural control, biological control and chemical control.
Harvesting and storage: Cucumbers can be harvested 7-10 days after flowering. The fruit stalk and part of the leaves should be retained at harvest time to maintain freshness. Attention should be paid to maintaining a suitable temperature and humidity during storage, and avoiding the influence of light and high temperature.
In short, mastering the planting methods and management techniques of cucumbers is of great significance to improve yield and quality. In practice, planting and management measures should be flexibly adjusted according to local climatic conditions and soil characteristics. Hopefully, this article can provide you with a useful reference and help for vegetable planting.
