The grafting of fruit trees and seedlings during the high temperature period in summer and autumn can not neglect the collection, storage and transportation of the scions of the improved varieties. The correct collection and transportation methods are as follows:
1. The scion collected at low temperature should be collected when the temperature is low in the early morning and the humidity of the air-phase tree is high. Should be collected well-grown, thick, full buds, old age of new shoots. After the branches are cut off, the young parts of the upper leaves and branches should be removed immediately, leaving part of the petiole or petiole. Every 30 to 50 bunches of scion are bundled into one bundle, and the hands should be light when strapping so as not to hurt the petiole and the skin. When bundling, try to bundle them together with the same length.
2. Moisturizing packaging The bundled branches are wrapped in 1-2 layers with wet cotton cloth. After the wrapping, they are gently put into the pouch soaked in fresh water, and then put into the basket for shipment. Remember not to use plastic film as a dressing and storage.
3, on the way to view the transport process to avoid high temperatures and exposure. In the middle of the journey, we must promptly check and find that the water loss of the packaging should be promptly sprayed with water. If the journey is far away, the scion should be taken out at rest, rinsed with clean water, placed in a cool place, and covered with wet cotton cloth to prevent loss of water.
4. After reaching the destination before storage, immediately remove the scion from the package and rinse it with fresh water 2-3 times. Then put it in a bactericide such as 1000 times solution of carbendazim or thiophanate-methyl solution. Seconds, dry thousands of liquids in a cool place, and store them in clean river sand in time. The place where the scion is stored should be shaded and ventilated, and the humidity of the river sand should be held in groups and loosen and scattered. Always keep the sand moist.
5. Grafting in time Under normal circumstances, the scion handled by the above measures can last for 7 days. Grafting should be organized as soon as possible, the sooner the better. According to the actual situation, the number of scoops for each dispatch and collection can be determined. Grafting should pay attention to the scion grafting, it is desirable to take a certain amount of scion into a bucket containing 3-5 cm of cold water, the scion is not in contact with the water can be covered with wet cotton cloth or wet towel, how much is taken from the bucket when grafting Scion.
