Pharmaceutical preparations play a very significant role in human beings. Drugs are all around us. If we have a cold, we will take some cold medicine, some people take capsules "Kangtaike", others take tablets "Gankang". Actually "capsule", "flake" this is medicaments preparation, the action of medicaments preparation is divided into two kinds generally. Some people do not want to take medicine when they are ill, because they hate the bitter taste of the medicine. The medicine is really bitter and hard to swallow. But when the drug is made into a sugar-coated pill, it saves the patient from suffering a bitter ordeal. Drug preparation can make medicine play its role and effect as "medicine". Insulin is a protein, which will decompose and lose its effect after being eaten by the human body.

2. Grafting method Grafting before injury period: tongue and split grafting should be adopted. Seedlings can also be grafted with wood. Grafting at the traumatic stage: subcutaneous grafting, split grafting, and single bud branch grafting. Splicing: mostly used for grafting before the injury period. Tongue connection: also used for grafting before the traumatic period. Subcutaneous connection: mostly used for grafting in the traumatic period and high-end replacement. After grafting, make a proper cut in the rootstock part under the grafting interface to make the wound flow out (shunt) partly to reduce the water accumulation in the grafting interface; or after the budding, keep the leaves of the rootstock under the grafting interface to reduce the grafting interface Standing water.
3. Attentions 1. In splitting and tongue jointing, it is advisable to choose the height of the rootstock at the same thickness as the scion thickness. Large gardens are grafted at the same height where most of the rootstock and scion thickness are equal. Small gardens can be grafted regardless of the height of the rootstock and grafted at the same thickness of the rootstock and scion. When the thick rootstock is split, insert two small scion in the incision of the rootstock to occupy the incision and promote early healing of the grafted section. For grafting seedlings, it is better to graft at a height of about 30 centimeters of seedlings, at the same height as the thickness of the rootstock and scion. It is not necessary to graft at the base.
2. After grafting, when the scion buds grow 3 to 5 leaves, and when the top growth point is exposed, dip the growth point into the branch to increase the growth advantage of the new shoot.
3, high-connected head, grafted 1.5 meters at the trunk. After grafting, wrap the rootstock with newspaper to prevent the rootstock from burning out. Before scion germination, a part of the rootstock sprouts in time to leave a leaf repeatedly topping. High-growth change head tree, 5 ~ 6 leaves topping and strengthening after scion sprouting, to prevent wind from breaking branches.
4. After the seedlings are grafted, insert a bamboo pole beside the seedlings in time to support the seedlings to grow upright. When the new tip becomes thin and entangled, untie it in time, straighten it, and keep growing upward. When you want to stop growing, choose 1 ~ 2 leaves on the top, remove the leaves, and leave the petioles to make them grow in succession.
