Tomato calcium supplement measures
Calcium-deficient tomatoes usually have short plants, water-stained light yellow-brown to dark green-brown spots on the navel of the fruit, uneven surface, and necrosis of diseased tissue (ie, umbilical rot). During the period of fruit expansion and maturity, if the calcium supply is insufficient, fruit cracking will occur, resulting in poor coloration and loss of luster. So how should tomatoes supplement calcium scientifically? 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 on the leaf surface, usually sprayed once every 7-10 days, Spray 2-3 times continuously to get a good calcium supplement effect. The ripening period of tomato fruit is the best time to supplement calcium. In addition, using superphosphate or calcium-magnesium-phosphate fertilizer as base fertilizer, 80-100 kg per mu, can significantly increase the calcium content of the soil. Adding retorted human, livestock and poultry manure and biological bacterial fertilizer can make the soil The content of active calcium is significantly increased, which is beneficial to the absorption and utilization of tomato roots and avoids calcium deficiency during tomato growth and development. If the tomato is planted in acid soil, when planting tomatoes on the ground, spread 50-60 kg of hydrated lime powder per acre to neutralize the acidity of the soil, increase the calcium in the soil, and ensure that there is sufficient calcium for the growth of tomatoes. need.

The main differences between powder,premixed agent, granule are as follows:
Veterinary Soluble Powder: means a dry powder preparation made of one or more drugs by grinding and evenly mixing, with or without dressing.
Premix: refers to one or more drugs, and a suitable substrate evenly mixed to make a powder or granular preparation.
As a dosage form of feed drug additive, it is specially used for mixed feeding.
Powder powder, that is, powder, and premixed agent, the main differences of granules are as follows:
1.the production method is different
1.powder: medicine or with appropriate auxiliary materials by grinding, evenly mixed dry powder preparation.
2.Veterianary premix: powder or granular preparation made by evenly mixing the drug with an appropriate substrate.
3.granules: raw materials and appropriate excipients mixed into a certain particle size of dry granular preparation.
2.different characteristics
1. Dispersing agent: compared with other solid dosage forms, dispersing agent is easy to disperse, dissolves quickly, absorbs quickly and takes effect quickly; The preparation process is simple, the dosage is easy to control, and it is easy for infants to take.
2.Premix for animal: Premix used in the matrix including carrier, diluent, etc. The substrate should be stable, with good fluidity, and easy to mix with drugs and feed.
3. Granule: the dispersion, adhesion, agglomeration and hygroscopicity of granule are lower than that of granule; The separation of various components in granule is avoided because of the adhesive used to make granule after mixing. Convenient storage and transportation; Particles can change their function by coating.
