Intestinal localization was administered to reduce adverse effects.
Targeted site-specific release:
Two
hours in gastric juice will not disintegrate or crack, dissolve within
thirty minutes of disintegrating juice, providing a perfect solution for
protein and peptide drugs and probiotics.

to the stomach or unstable under acid, or dissolved and effected in the
intestine.
Intestinal location administration can improve the

This technology has been rapidly promoted in agricultural production in recent years. However, there are many types of foliar fertilizer on the market, and the quality varies greatly. Therefore, it is very important to distinguish the quality of foliar fertilizers. Now from the appearance of simple identification, put forward three methods for reference. Look at the packaging and instructions. The varieties of foliar fertilizers that meet the national quality requirements shall be marked in the following aspects: First, the name of the product, the name and address of the manufacturer, followed by the agricultural registration number of the fertilizer, the product standard number, the name and content of the active ingredient, and the net weight. The date of production; the last is the crop, applicable area, method of use and what should be noted for the product. Look at the dissolution.
A bag of foliar fertilizer can be mixed with about 1 kg of water to see if it dissolves. If all the precipitates do not dissolve, it means that the product is of good quality, the content of effective nutrients is high and can be easily absorbed by crops; if it is not completely dissolved, there is a sediment on the bottom of the water, indicating that the product is of poor quality, and it is easy to block the sprayer nozzle during spraying. The absorption rate of nutrients is not high. Look at the dosage form and dryness.
There are currently two types of solid and liquid foliar fertilizers on the market. Solids are generally better than liquids. Solid foliar fertilizer is divided into two kinds of granular and powdery, granular than powder. Because of the granulation processed by a special process, it has the advantages of convenient application, high degree of drying and easy storage.
