Nowadays, there are many places in the sheds, mainly because the economic benefits are high and fast. They can list all kinds of fruits and vegetables in different seasons. Recently, how can farmers consult the cucumbers in the cold winter greenhouse? Let's take a look at it together.
First, increase the application of organic fertilizer
During the growth and development of cucumber, organic fertilizer is very important, which not only can increase the porosity of the soil, but also effectively improve the physical and chemical properties of the soil. In general, it is also possible to apply 2,500 kg to 3,000 kg of decomposed round manure or 5,000 kg of soil dung per mu.
Second, rational application of fertilizer
The root system of cucumber is not deep, so the fertilization concentration must be controlled well, not too high, because it will lead to root burning. The base fertilizer can be used to apply twenty-five to thirty kilograms of diammonium per acre and twenty-three to twenty-seven kilograms of potassium sulfate. Of course, in the growth process of cucumber, it is also necessary to topdress in time. The total amount is generally 47 to 53 kg of urea and 52 to 58 kg of potassium sulfate.
Third, spraying foliar fertilizer
Cucumber needs to be combined with the application of foliar fertilizer in the season of fruiting, and the foliar fertilizer can supplement the strong fertilizer requirement of cucumber at this time. Pay attention to the deep winter season, you need to spray the agent to prevent premature aging of cucumber plants.
Fourth, the application of biological fertilizer
Increasing the application of organic fertilizers and biological fertilizers, and appropriately reducing chemical fertilizers are inevitable choices for the production of pollution-free green food. The newly built shed will apply 8 kg of high-quality bio-organic fertilizer once, which will make the cucumber grow robust, sit more melons, grow melons, and extend the picking period.
The above is the main point of fertilization technology for greenhouse cucumbers. I hope to help every greenhouse grower who grows cucumbers. If you have other direct messages you want to know or want to add!
