- Abstract
[Objective] This study was conducted to change the situation of high cost in walnut grafting by reducing seedling cost through technical means. [Method] Effects of different rootstock processing methods and rootstock pruning time on walnut growth and cost were studied by the square bud grafting method. [Result] The survival rate and cost under stumping were higher than those under no stumping, and the proportion of grafting-capable rootstocks under stumping was lower than that under no stumping by 9%. The cost differences between different rootstock time were remarkable. The cost for the stock pruning 15 d after grafting was 5 times as much as 1 d after grafting. [Conclusion] Direct grafting could achieve the effect of easy and convenient management, and the overall cost was lower though the survival rate was reduced to a limited extent. Sooner rootstock pruning resulted in a better effect. Pruning the rootstocks within 5 d after grafting not only could improve the quality of seedlings, but also could reduce the cost for seedling management.
