How to add calcium to tomatoes

Calcium-deficient tomatoes are usually short plants with water-stained light yellow-brown to dark green-brown spots on the umbilicus of the fruit, uneven surfaces, and necrosis of the diseased tissue (ie, umbilical rot). During the period of fruit expansion and maturity, if the calcium supply is insufficient, cracking will occur, resulting in poor coloring and loss of gloss. So how should tomatoes be calcium supplemented scientifically?

Foliar spray 0.3% -0.5% calcium nitrate aqueous solution, or 0.1% -0.2% calcium chloride aqueous solution, or 400-500 times active calcium aqueous solution, or 600-800 times fluid calcium aqueous solution, generally sprayed every 7-10 days, Continuous spraying 2-3 times, it has a good calcium supplement effect. The best time for calcium supplementation is during the swelling and ripening of tomato fruit.

In addition, the use of superphosphate or calcium magnesium phosphate fertilizer as the base fertilizer, 80-100 kg per acre, can significantly increase the soil's calcium content, the addition of manure, livestock, poultry manure, and biological bacterial fertilizer can be used together to make the soil ’s The content of active calcium is obviously increased, which is conducive to the absorption and utilization of tomato root system and avoids calcium deficiency during tomato growth and development. If the tomato is grown in acid soil, when planting tomatoes, apply 50-60 kg of cooked lime powder per acre to neutralize the acidity of the soil and increase the calcium in the soil to ensure that sufficient calcium is available for tomato growth and development. need.

Health Ingredients

Health foods contain a certain amount of functional health ingredients, which can regulate the functions of the human body, have specific effects, and are suitable for specific groups of people. General food does not have specific functions, and there is no specific range of people to eat. Health food cannot be directly used to treat diseases. It is a human body mechanism regulator and nutritional supplement.

The human body needs many nutrients, such as water, protein, fat, carbohydrates, vitamins, minerals, dietary fiber,etc. Nutritional products are generally rich in these nutrients and suitable for everyone. Its nutritional value of health ingredients is very high and it is suitable for everyone to drink. While health food is food with specific health functions and only suitable for specific groups of people, and its nutritional value is not necessarily high. Therefore, the various nutrients that the human body needs are still obtained from three meals a day. Of course, health care products are better in some aspects. Health care products can obtain more fixed health functions than nutrition products. The minerals of the human body are not balanced, so health care products have a greater advantage in some aspects.
