Four points of effective calcium supplementation during tomato flowering and fruit period: Choose the right calcium fertilizer When supplementing calcium, choose a good calcium fertilizer product, such as chelated calcium fertilizer (such as sugar alcohol calcium, Amino Acid calcium, etc.). Chelated calcium fertilizer can break the barrier, conduct in the phloem, and improve the absorption efficiency of calcium. Select mineral molecule calcium, which is not easy to be fixed, easy to absorb, and has high absorption and utilization rate. It is not affected by soil and weather adversity. It also contains boron and other trace elements to further promote the absorption of calcium. The spray site should be correct The mobility of calcium in the plant body is very poor. When it is lacking, it will first appear in the young growth point. Therefore, when performing foliar calcium supplementation, we should focus on spraying the young part of the plant, that is, focus on the shoot tip growth point. Spray the distance below 30 cm, while focusing on the young fruit. Generally, when the tomato enters the flowering period or the fruit grows to the size of a soybean, it is necessary to replenish calcium fertilizer in time, and spray it continuously for 2 to 3 times. In addition, foliar calcium supplementation can increase nutrients such as potassium, zinc, and boron at the same time, which can promote the absorption of calcium and improve the utilization of nutrients. Pay attention to soil moisture content during flushing Root absorption of calcium is accompanied by water absorption. If vegetable farmers control water for a long time, it will cause tomato roots to lose water and plants will wilt, which will increase the difficulty of roots' absorption of calcium (especially after the tomato enters the fruiting period and the soil is dry. It is easy to cause high incidence of fruit umbilical rot); too much watering can easily cause root retting and affect the absorption of calcium by the root system. Therefore, calcium supplementation during the flowering and fruit period should ensure that the soil moisture is reasonable, and the soil should see dry and wet. Avoid partial application of fertilizer In the flowering and fruiting period, in order to promote the rapid expansion of tomato fruits, vegetable farmers are often used to large water and fertilizer, such as high-nitrogen type, high-potassium type, etc., which leads to excessive nitrogen, phosphorus and potassium content in the soil, which affects calcium absorption. In fact, after the tomato blossoms and sets fruit, in addition to paying attention to fruit expansion and supplementing nitrogen, phosphorus and potassium nutrition, attention should also be paid to the application of functional fertilizers containing humic acid, chitin, and alginic acid. While improving the soil, it can also increase the root system. Absorption and utilization of nutrients, reduce the incidence of calcium deficiency.

It is a micronutrient required by living organisms, but generally cannot be produced by living organisms themselves, and needs to be obtained by means such as diet. Vitamin is a kind of low molecular compound necessary for the body to maintain normal metabolism and function. It is one of the six nutritional elements (sugar, fat, protein, salt, vitamin and water). Most must be obtained from food, and only a few can be synthesized in the body or produced by gut bacteria. The daily requirement of the human body for vitamins is very small, but once lacking, can cause a special kind of disease, called "vitamin deficiency disease". Primary vitamin deficiency can be caused by insufficient intake due to a lack of vitamins in food or a reduction in the amount eaten. Secondary vitamin deficiency can be caused by a decrease in the body's ability to absorb vitamins, an increase in the body's vitamin requirement, or the interference of some drugs. Our main products are: vitamin A, vitamin B1 (thiamin), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin B6, vitamin B7 (biotin), vitamin B9 (folic acid), vitamin B12, choline, vitamin C, vitamin D, vitamin E, vitamin K.
