Cucumber is an infinitely growing vegetable. It is fertile and has a fast growth and many results. However, the root system is mainly distributed in the shallow tillage layer of 15~25cm, and the leaf surface water transpiration is large, the plant stem is thin, the fertilizer and water resistance is weak, and the absorption is stronger. difference.
Cucumber has a long growing period, high yield, and large nutrient uptake, suitable for fertile soil cultivation. Re-application of organic fertilizer, appropriate application of chemical fertilizers, master the principle of "less eating more meals, combining fertilizer and water" is the basis for obtaining high quality and high yield of cucumber.
Fertilization type selection
Organic Fertilizer
Organic fertilizer is a complete fertilizer, and the three elements of nitrogen, phosphorus and potassium and various trace elements are relatively comprehensive.
In the greenhouse cucumber production, due to the low temperature and ground temperature in the early spring, the root activity is inhibited, and the ventilation of the facility is reduced, the indoor carbon dioxide will be seriously deficient, and the photosynthetic yield will be significantly reduced.
A sufficient amount of organic fertilizer must be applied, which not only supplies various nutrients necessary for the growth of the crop, but also plays a major role in activating soil nutrients and improving soil aggregate structure.
Be sure to pay attention to whether the applied organic fertilizer is decomposed, otherwise it will cause burns, pests and diseases, soil acidification and other hazards.
Biological fertilizer
Generally, the soil plough layer contains 180 kg and 120 kg of total potassium and total phosphorus per mu, but 80 to 90% of the crops cannot be directly absorbed and utilized.
The application of biological fertilizer can accelerate the decomposition and transformation of soil organic residues and poorly soluble phosphorus, potassium and other mineral nutrients.
Compound fertilizer
Mainly used for base fertilizer and top dressing, pay attention to the application method.
The amount of soil topdressing should be based on the principle of less and diligent, and it is generally appropriate to chase 40kg~50kg per shed every time. If you feel that the amount of fertilizer is insufficient, you can increase the number of top dressings.
It is strictly forbidden to plant the cucumber in the shed, and it is strictly forbidden to dry and apply the ditch. It must be applied with the ditch. In the high-yield period, every fertilizer should be made to maintain the high-yield period.
Foliar spray fertilizer is generally in the middle and late stages of production. For example, in the late growth stage, the leaves spray high-purity potassium dihydrogen phosphate (phosphorus potassium source pool), which can increase the disease resistance of cucumber, delay aging, and strive for high yield in the later stage.
It is best to spray the foliar fertilizer separately from the spraying agent. When it is necessary to spray at the same time, it should also be sprayed in the morning and sprayed in the afternoon to prevent phytotoxicity.
Cucumber fertilization program
Base fertilizer
Cucumbers are high-yield crops and require a higher amount of base fertilizer. Cucumber belongs to high-nitrogen and high-potassium crops. Formula fertilization generally requires 30 kg of compound fertilizer + 2000-3000 kg of decomposed organic fertilizer + 7.5 kg - 10 kg of high-quality biological fertilizer per acre.
top dressing
After planting, the fertilizer is topdressed 1 or 2 times according to the growth of the plant.
For the first time, the seedling fertilizer can be applied 7 to 10 days after planting, and the sea snail biostimulator 200~300 times solution can be applied to facilitate the rapid rooting of the crop and rapid seedling raising.
For the second time, before pumping the vines to the flowers, a large amount of elemental balanced fertilizer 3 kg + 2 kg of sea elf bio-stimulant was applied per acre to promote the flowering result.
When the melons sit and grow to 10-15 cm, they should be fat when they are watered, and gradually begin to enter the normal watering and fertilizer stage, and supplement the foliar fertilizer at the right time.
Mainly based on high-nitrogen and high-potassium fertilizers, the sea snail bio-stimulant containing ore source humic acid is appropriately added to improve soil physical and chemical properties and improve nutrient levels.
When it is found that the melon is serious, the melon leaves are hypertrophy, and the deformed melon is more, the 0.2kg of the phosphorus potassium source pool is used to stir and dissolve 100kg of water, and the leaf surface is sprayed, once every 3-5 days, which can be effectively alleviated. If other trace elements are missing, pay attention to supplement.
After entering the harvesting period, the fertilizer should master the principle of light pouring and deep pouring, and the amount of fertilizer should be light and heavy.
Depending on the growth and harvesting of the plant, each acre is applied with a large amount of elemental balanced fertilizer 2 kg + high potassium fertilizer 3 kg + sea elf bio-stimulant 5 kg, it is recommended to apply fertilizer for 10 days.
