Several ways of calcium supplement for grapes the methods of efficient calcium supplement are all here.

As one of the necessary elements for the growth and development of grape, the importance of calcium is self-evident. Some data even show that grapes have the third highest demand for calcium after potassium and nitrogen. I'm afraid this is different from the three major elements of nitrogen, phosphorus and potassium. When grapes enter the Pengguo stage, the demand for calcium will increase rapidly. at this stage, the demand for calcium will also reach its peak, stimulating the development of pulp cells. at this time, if there is a lack of calcium, not only the yield will be low, but also the quality will decline a lot, such as cracking fruit at maturity.

Friends who have studied chemistry must be well aware that the chemical properties of calcium ions are very unstable, reacting with hydroxyl radical in alkaline environment and acid radical in acidic environment, that is to say, calcium ions may not be able to be absorbed by grapes in either acid or alkaline environment. The calcium on the market mostly uses chelating agents to chelate calcium ions to avoid reacting with other ions to achieve the purpose of improving the utilization rate of calcium. So how to supplement calcium for grapes? Here are some suggestions to share several ways for you to develop agriculture through science.

Increase organic fertilizer

There is no need to say more about the introduction of organic fertilizer, which has been explained many times before. Organic fertilizer has a comprehensive nutritional structure and can supplement a certain amount of calcium for grapes. Organic fertilizer can be applied once in the Spring and Autumn period.

Root fertilization

The practice of topdressing calcium fertilizer on roots has also been mentioned earlier, this method is actually not efficient in the use of calcium, calcium superphosphate and calcium nitrate are commonly used in production, but although the utilization efficiency of this method is not high, but it is also a way to increase calcium application.

Foliar calcium supplement

It has been introduced earlier that when grapes enter the fruit expansion stage, the demand for calcium in grapes reaches the peak, so calcium fertilizer must be applied. When the grape fruit grain rate is big, calcium nitrate (concentration 0.5%) can be sprayed. Calcium is an inert element in plants, and its mobility is poor, so even if a large amount of spraying can not achieve the purpose of efficient utilization, scientific agriculture is suggested here. So as to improve the utilization rate of calcium and supplement the demand of plants for calcium. (there are also other calcium preparations in production, such as available calcium fertilizer, amino acid calcium, etc.)

Mature storage and calcium supplement

At this time, the main purpose of calcium supplement is to prevent grape fruit from cracking, and the grape fruit is deficient in calcium due to metabolism during storage. therefore, when harvesting and storage, soaking the fruit with calcium preparations such as calcium amino acid 300 times dilution can improve storage quality and prevent storage from calcium deficiency.

The above is the scientific development of agriculture on grape calcium supplement point of view, I hope it can be helpful to you.
