1. There are many factors that cause cucumber malformation, but the main factor is improper fertilization.
2. The proportion of fertilization should be appropriate. Cucumber requires nitrogen, phosphorus and potassium. The seedling stage is 4.5:1:5.5, and the melon period is 2.5:1:3.7. The ratio of nitrogen to potassium is greater than that of phosphorus. The potassium requirement is greater than nitrogen, so potassium fertilizer application can not be ignored.
3. The amount of fertilizer applied is too large, and the soil salt concentration is high, which hinders the cucumber from absorbing water and nutrients. This not only affects the growth of cucumber plants, but also the shape of the melons. Therefore, the amount of cucumber to be fertilized should be N2.8-3.2 kg, P2O5 1.2-1.8 kg, K2O 3.6-4.4 kg for every 1000 kg of cucumber produced.
4. Pay attention to the later fertilization. With the harvest of cucumber, the nutrients are continuously consumed, and a stable and long supply of nutrients is needed. If the topdressing is neglected in the later stage, the cucumber is prematurely deficient due to lack of fertilizer, the effective harvesting period is shortened, the cucumber yield is decreased, and the deformed melons such as curved melons are increased. In order to ensure the needs of later nutrients, generally cucumbers need to be topdressed 8-10 times after planting, but also combined with the application of organic fertilizer.
