Calcium is one of the 16 elements required for plant growth and development, and it plays a very important role in the process of plant growth and development. The main reasons for calcium deficiency are high demand, low supplementation, low absorption, and poor mobility.

Three ways to supplement calcium fertilizer

How to supplement calcium with the most significant effect?


(1) Supplement of base fertilizer: fertilization is the main fertilization method of calcium fertilizer during soil preparation, which can not only supplement calcium, but also improve the soil. In the southern acidic soil or the acidified soil under the cultivation of protected land, 50-100 kilograms of quicklime is generally applied; in the northern alkaline soil, 100-200 kilograms of gypsum can be applied per mu. Basically meet the needs of plant growth.


(2) Flushing with water: during the flowering and fruiting period of the plants, there is a large demand for calcium, which can be combined with watering. Each acre topdressing a large amount of calcium-containing water-soluble fertilizer 6-10 kg acres. Calcium exists in a chelated state and is easily absorbed by plant roots. It is the most effective way to supplement calcium.


(3) Foliar spraying: Foliar spraying is a quick way to replenish calcium fertilizer, but the amount of foliar spraying is small, and it is difficult to meet the needs of plant growth and development. Therefore, foliar spraying must be advanced, and To choose calcium sugar alcohol or chelated calcium that is easily absorbed by crops, generally start to use before flowering and fruit. 20-30 grams of calcium sugar alcohol can be used per mu each time, and 30 kg of water can be sprayed evenly, spray every 10-15 days Once, spray regularly.


Of these three calcium supplement methods, the second one has the highest absorption and utilization rate and can be widely used in tomatoes, eggplants, peppers, watermelons, apples, pears, peaches and other crops.
