| Abstract: | Objective]The reserach aimed to provide key technology for the quick reproducing of walnuts grafted seedlings and reduce the nursery cycle.Method] Compare the results of bud grafting outdoors and seedlings grafting in the same time,bud grafting outdoors adopts the most advanced and popular square bud grafting,seedlings grafting adopts the innovative under-skin grafting of contraposition bud.Result] The highest survivability of seedlings grafting is 98.1%,the highest survivability of bud grafting outdoors is 75.3%,the survivability of seedlings grafting is 22.8% higher than the survivability of bud grafting outdoors,the average survivability of seedlings grafting is 80.3%,the average survivability of bud grafting outdoors is 65.4%,the average survivability of seedlings grafting outdoors is 14.9%;The average highest height of scion of seedlings grafting is 81.8 cm,the average highest height of scion of bud grafting outdoors is 75.1 cm,the height of scion of seedlings grafting is 6.7cm higher than the bud grafting outdoors;the average height of scion of seedlings grafting is 60.3 cm,the average height of scion of bud grafting outdoors is 54.9 cm,the average height of scion of seedlings grafting is 5.4 cm higher than the scion of bud grafting outdoors.Conclusion]The survivability of seedlings grafting is very high and the seedlings are of high quality.It is easy to operate,which can reproduce quickly,save labor,save materials,and has a low cost.The cycle of nursing seedlings is short and easy to be accepted by people.This technology takes lead among the reported advanced technology and methods all over the world. |
