1.The period after seedling emergence.：Drip irrigation  Fish protein 3-6 kg/acre, once in total.

2.The vining period：Drip irrigation  10-48-10+TE/15-30-15+TE Alternate use of 3-5 kg/acre/time, every 7-15 days/time, once each.

3.Flowering stage：Foliage spray  EDTA-TE（Flower and fruit） 1000-1500 times dilution per application, every 7-15 days/time, continuous use.

4.Flowering stage：Drip irrigation Seaweed fertilizer 3-5 kg/acre/time, every 7-15 days/time, 3 times in total.

Foliage spray  CA fertilizer 800-1000 times dilution per application, every 7-15 days/time, continuous use.

5.fruiting stage：Drip irrigation 25-10-20+TE/12-6-42+TE Alternate use of 3-5 kg/acre/time, every 7-15 days/time.

6.For each subsequent batch of fruit growth, fertilize according to the above recommendations from the flowering period to fruit maturity.

5-60-340+TE：After cucumber encounters pests and diseases and is treated with drugs, spraying potassium dihydrogen phosphate can provide nutritional elements and protect cucumber at the same time.
Humic acid water-soluble fertilizer：If the soil for planting cucumbers is affected by salinization, compaction, poor water retention and fertilization, flushing with fertilizers can effectively improve the soil environment and replace other fertilizers with large amounts of nutrients.
EDTA-TE（Green leaves）：Spraying the leaves with foliar fertilizer in the later stage of cucumber fruiting can prolong the life of functional leaves, thereby increasing yield and income.

Growth habits of cucumbers:
Cucumbers are annual herbaceous plants in the Cucurbitaceae family, and their growth cycle can be divided into four stages: germination, seedling, vine elongation, and fruiting. According to research, cucumbers are typical warm-loving and cold-intolerant crops, with a suitable temperature range for growth of 15℃ to 32℃, with nighttime temperatures of 15℃ to 18℃ being optimal. Cucumbers are not cold-tolerant, and growth stops at temperatures of 10℃ to 13℃, and they can be damaged by freezing temperatures below -1℃ to 0℃. Cucumbers like strong light but can tolerate weak light. Short daylight and low nighttime temperatures promote female flower differentiation. Cucumbers are water-loving plants. In hot and dry environments, they are prone to wilting, which affects photosynthesis. The suitable relative humidity for cucumbers is 60% to 90%, and the suitable relative soil moisture content is 60% to 70%. Cucumber cultivation should fully meet the requirements for temperature and water and fertilizer. Cucumbers prefer fertile soil rich in organic matter. They do not grow well in clay soil, but grow better in sandy soil, although sandy soil is prone to aging. Cucumbers prefer weakly acidic to neutral soil, with a pH range of 5.5 to 7.2 being optimal.

The fertilization requirements of cucumber:
Studies have shown that cucumber absorbs 2.8kg of nitrogen, 0.9kg of phosphorus, 9.9kg of potassium, 3.1kg of calcium, and 0.7kg of magnesium per ton of fruit produced. Cucumber has a weak root system and poor fertilizer absorption ability. Therefore, it is necessary to apply sufficient base fertilizer before transplanting. During the winter and spring cucumber growing season, because of low temperature and less water consumption, at most two times of watering and fertilization can be carried out during this period. After the temperature rises, the growth of cucumber accelerates, and the number of topdressing and watering should be increased accordingly.
