What to Do When Vegetables Are Deficient in Calcium? Detailed Remedial Measures
Vegetables are an indispensable dish in our daily lives. Eating vegetables can supply the human body with various nutrients and is extremely beneficial to human health. There are many varieties of vegetables in our country, and the vegetable planting area in our country is also very large. Vegetables also have relatively large nutritional needs during growth. This is especially true of the calcium element, so when we grow vegetables, what should we do if there is a calcium deficiency? Let's take a look together below!
1. Choosing calcium fertilizer
In the process of growing vegetables, if you find that the vegetables show signs of fertilizer deficiency, then calcium fertilizer must be supplemented in time. The choice of calcium fertilizer is very important, and the commonly used type now is mainly chelated calcium fertilizer. Chelated calcium fertilizer can be effectively conducted into the phloem of vegetables, improving the amount of calcium element absorbed by vegetables. In addition, we can also choose some mineral calcium. Mineral calcium is not easily fixed, which is beneficial to the absorption of vegetables. At the same time, it will not be affected by factors such as soil and weather. It also contains some other trace elements, which is very beneficial to the absorption of calcium.
2. Application period
When applying calcium fertilizer, we should pay attention to controlling the application period well. The first time should be during the seedling stage of the vegetables, because for most vegetables, after transplanting, it is an important period for root development. At this time, properly supplementing some calcium fertilizer can enhance the growth capacity of the vegetable roots and promote flower bud differentiation. Then calcium fertilizer should be applied again during the flowering and fruiting stage, because this period is the peak period of nutritional demand for many vegetables. As for the common nitrogen, phosphorus and potassium elements, the absorption speed is relatively fast, and there is basically no shortage. However, calcium fertilizer is relatively difficult to supplement, so attention must be paid to doing a good job of calcium fertilizer supplementation during the flowering and fruiting stage.
3. Application site
When applying calcium fertilizer, we should pay attention to understanding which parts of the vegetables are prone to calcium deficiency and supplement accordingly. Generally speaking, the young and tender parts of vegetables are more prone to calcium deficiency. Moreover, the calcium element in vegetables basically does not move. Therefore, when we spray foliar fertilizer to supplement calcium, we should focus on the young and tender parts of the vegetables. If there is fruit, then attention should also be paid to spraying the young fruit. Usually once about a week, spraying about three times. Moreover, when spraying foliar calcium, some elements such as potassium and boron can also be properly supplemented, which can mutually promote absorption.
4. Soil environment
The soil environment has a great relationship with the absorption of the calcium element by vegetables. When vegetable roots absorb the calcium element, they generally absorb it in combination with water. Therefore, when applying calcium fertilizer, we should pay attention to maintaining good soil water content. Generally, the suitable soil water content for many vegetables is around 75%. In addition, we should focus on controlling the nutrient ratio well, and must never apply excessive nitrogen fertilizer, phosphorus fertilizer, etc., and also control the amount of fertilizer applied well. Avoid excessive soil salt concentration, which would hinder the absorption of the calcium element by the roots.
The above is a brief introduction to what to do when vegetables are deficient in calcium. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
