4 taboos when growing cucumbers

Cucumbers are not only edible all year round, but also have high nutritional value and beauty benefits, so they are deeply favored by consumers. As the number of growers increases, the yield and quality of cucumbers cannot be fully guaranteed due to insufficient planting management and technical services. Let’s learn the 4 taboos of planting cucumbers.

1. Use pesticides correctly

In order to save trouble, some farmers may mistakenly pursue high concentrations of pesticides, but the concentration of pesticides is closely related to the effectiveness of pest control. Improper use of pesticides not only results in poor results, but may also lead to pesticide resistance and increase subsequent prevention and control costs.

Using pesticides with too low a concentration will result in unsatisfactory control effects, which may lead to increased resistance of pests and diseases to pesticides and increase subsequent control costs. Using pesticides with too high a concentration may cause phytotoxicity to cucumbers under high temperatures and rapidly evaporating water, damaging stems and leaves and causing a waste of resources.

2. Reasonable nitrogen fertilizer application

Excessive application of nitrogen fertilizers while neglecting phosphorus and potassium fertilizers, or applying fertilizers too early, can cause excessive growth of cucumber plants. Therefore, when applying fertilizer, you should formulate fertilizer according to the soil test results, balance the ratio of nitrogen, phosphorus and potassium, increase organic fertilizers , supplement trace elements, and combine water and fertilizer management to promote nutrient absorption.

3. Avoid over-irrigation

Excessive irrigation will lead to excessive soil moisture and poor air permeability, causing the cucumber roots to rot in an oxygen-deficient state, affecting nutrient absorption and weak plant growth. At the same time, it will also cause waste of water resources. We should adopt the method of frequent watering with small amounts of water and establish an efficient drip irrigation system to achieve precise irrigation.

4. Choose suitable seedlings

Some people believe that choosing larger cucumber seedlings can increase the survival rate and shorten the seedling acclimatization period. But in fact, seedlings that are too large have serious root corking and are easily broken during planting, affecting survival. Seedlings that are too large have strong transpiration from leaves and weak water absorption capacity from roots, which can easily lead to death. It is generally recommended to select seedlings that are about 35 days old, have dark green leaves, thick leaves, 3-5 true leaves, and a well-developed root system.

The above is an introduction to the four major things to pay attention to when planting cucumbers. Many friends who plant cucumbers do not master the relevant planting knowledge and blindly expand the area. Be careful not to lose more than you gain.
