Chrysanthemum skillfully connected to low temperature easy to survive
Chrysanthemum and Artemisia both belong to the same family of Asteraceae, and they have strong affinity and high grafting survival rate. However, due to the limitation of temperature and time, the difficulty of grafting chrysanthemum on hot summer increases, and the survival rate is extremely low. After several years of theory and exploration, the survival rate of chrysanthemum grafting in the low-temperature season has the following points:
Cloudy days are the best time for low-temperature season grafted chrysanthemums, followed by windless days before 10 am and next afternoon 4 pm. Two or three days prior to grafting, the primary rootstock and scion mothers were watered once to increase the water content of the scion and rootstock. One or two hours prior to grafting (referring mostly to the low-temperature and dry-down afternoon), watering the rootstocks and the mother plants of the scions was performed so that the mother plants would not suffer from mental wilts due to sun exposure during the grafting process. However, attention should be paid to the water on the leaves. All the evaporation and then start grafting. Prepare a wealthy plastic bag (available on the instant noodles), soak it in the water and put it out for use.
Grafting and grafting methods should be adopted. Rootstocks and scions should be developed. Old and tender, excessive, no white pulp, and the rootstock diameter of 3 to 4 mm, slightly larger than the scion. With picking and picking, scion should not be overdone at a time to avoid the effect of falling water.
Pick a 5-7 cm long seedling as the scion. To lose the lower part of the larger leaves, the top leaves two or three leaves. The scion is cut into 15 cm long wedges with a double-sided blade, and then the rootstock is cut from the grafting site and cut open from the middle of the rootstock with a knife, which is slightly longer or equal in length (1.5 to 2 cm) than the cutting surface. Pull the scion out of the mouth, the two layers should be aligned, with the plastic bar to entanglement the interface from top to bottom, and moisturize the cross-section of the rootstock, put on the plastic bag, and tie the bag. When the bag is to be bagged, the scion shall be placed in the bag along with several pieces of Artemisia leaves under the interface. If the Artemisia leaves are less or smaller under the interface, several pieces of Artemisia leaves should be taken from other places, soaked in water and then put into the bag. Be careful when handling to avoid colliding and losing scion. All grafting process should be quick.
Immediately after grafting, the method of shading was accepted, and the small area was soaked in newspapers or kraft paper, and then all the grafted parts were concealed with the aid of bamboo scaffolds. The first day or two should be sprayed in real time when the newspaper or kraft paper is dry, and the paper will become wet. The area of ​​the available shade nets is shaded.
Two or three days later, turn the plastic bag over a small mouth and watch the inspection. If the scion does not show signs of wilting, you can remove the sunshade after six or seven days. Scion radically removes the sunshade after it survives. It's a good day to pay attention to the water spray. Spray it three or four times a day. At the same time, add a large amount of air on the bag. When the weather is particularly hot and dry, spray it into the bag to make the scion slowly adapt to the outside world. If the invention scion wilting life should be connected in real time. In 20 days, your scion began to develop agilely and you should lose the plastic strip on the scion in real time.
