Causes of calcium deficiency and main points of calcium supplement in cucumber

Cucumber is a common vegetable in our life, and calcium deficiency is also a common phenomenon in the process of planting, which will seriously affect the yield and quality of cucumber. So what is the reason for calcium deficiency in cucumbers? How to supplement calcium? Let's get to know it with the editor.

I. causes of calcium deficiency in cucumbers

1. The lack of calcium in soil is the main reason for calcium deficiency of cucumber, which often occurs in sandy soil, old vegetable garden, continuous cropping vegetable garden and vegetable garden with low content of organic matter.

2. There is generally no calcium deficiency in soils with low available calcium content, mainly because ammonium, potassium, sodium and magnesium ions dissolved in the soil can antagonize calcium ions, thus inhibiting the western absorption and utilization of calcium ions in plant roots, resulting in calcium deficiency.

3. The absorption of calcium by the root system is mainly carried out by improving the root tip. If the root growth and development is poor and the absorption capacity is poor, the phenomenon of calcium deficiency will occur.

4. the mobility of calcium in plants is poor, and the main power of transpiration in plants depends on transpiration liquid flow, so the organs with higher transpiration intensity and longer growth time will transport more calcitonin, resulting in less calcitonin in the upper leaves.

Second, calcium supplementation

Calcium supplementation of cucumber can prevent physiological diseases, increase calcitonin nutrition, effectively control various physiological diseases caused by calcium deficiency, increase yield and varieties, and calcium can promote root absorption, cell division and carbohydrate and protein synthesis. Calcium can reduce the activity of ethylene synthase, respiratory radish, inhibit cell senescence and improve the storage and transport of fruit. In addition, calcium is an important component of cell wall, which can increase the hardness of cells and organs and increase the firmness of fruit.

Third, the main points of calcium supplement

The main results are as follows: 1. on the basis of phosphorus and potassium, sandy soil should apply calcium-magnesium phosphate fertilizer, calcium superphosphate, calcium nitrate and other calcium fertilizers. For the old vegetable garden, lime powder can be added to supplement calcium content.

2. Foliar fertilizer can be sprayed with 1-2 jin of calcium superphosphate for every 100 kg of water. Zizania caduciflora is soaked for a period of time after half an hour, and the leaching solution above is sprayed. Calcium amino acid and humate can also be sprayed during the peak period of calcium absorption by vegetables.

3. When applying nitrogen and potassium fertilizer scientifically, there is antagonism between ammonium ion, potassium ion and calcium ion, and when nitrogen fertilizer is high, it will also inhibit the absorption of calcium, so it is necessary to properly control the application of nitrogen and potassium fertilizer.

4. Increase the application of organic fertilizer, organic fertilizer is rich in organic matter and a variety of nutrients needed for crop growth, which plays an excellent role in improving soil and soil fertility.

The above are the reasons for calcium deficiency of cucumber and the main points of calcium supplement. I hope it can help you. If you want to know more about it, please follow us.
