Improper Fertilization Causes Prevention of Cucumber Malformation
There are many factors that cause cucumber deformity, but the main reason is improper fertilization. Pay attention to the following points when fertilizing:
1. The proportion of fertilizer should be appropriate. Cucumber needs the proportion of nitrogen, phosphorus and potassium, the seedling period is 4.5:1:5:5, and the melon period is 2.5:1:3.7. The ratio of potassium to potassium is greater than that of phosphorus, and the requirement of potassium is greater than that of nitrogen, so the application of potassium fertilizer cannot be ignored.
2. The amount of fertilizer is too large, and the soil salt concentration is high, which prevents the cucumber from absorbing water and nutrients. This not only affects the growth of cucumber plants, but also the malformation of the melons. Therefore, the amount of cucumber fertilization should be appropriate, generally 2.8-3.2 kg of nitrogen, 51.2-1.8 kg of phosphorus pentoxide, and 3.6-4.4 kg of potassium oxide per 1000 kg of cucumber.
3. Pay attention to late fertilization. With the harvest of cucumber, nutrients are continuously depleted and stable and long supply of nutrients is required. If the top dressing is neglected at the later stage, the cucumber is prematurely attenuated due to lack of fertilizer, the effective harvesting period is shortened, the yield of cucumber is reduced, and the malformation of melons such as melons are increased. In order to ensure the need of nutrients in the later period, generally cucumbers need to be topdressed for 8 to 10 times after planting, but also combined with the application of organic fertilizers.
