Method for grafting kiwifruit on rootstock

Abstract

The invention relates to the technical field of kiwifruit propagation, and discloses a method for grafting kiwifruit on rootstock. The method comprises the following steps that 1) in the middle ten days of February every year, kiwifruits with excellent varieties and strong growth are selected, vigorously growing branches are cut from kiwifruit trees by using a sharp thin grafting knife to serve asscions with the length of 20 cm, the cut scions are soaked in a 5% carbendazim 50-fold solution for 3 hours to perform disinfection treatment, a notch is cut on wild sweet potato vine rootstock at aposition 10 cm away from the ground by using a grafting knife, the treated kiwifruit scions are quickly inserted into the notch of the wild sweet potato vine rootstock, the scions are immediately bound and fixed by using thin film strips, a water outlet is cut 3-5 cm below the grafting part, 1-2 large incisions are required to be inclined and staggered with each other, and the depth is 1 / 5-1 / 7 ofthe diameter of the rootstock; and the wild sweet potato vine rootstock is subjected to cutting propagation, stolons are cut in February to March in Yunnan, the stolons are cut into cuttings with thelength of 20-40 cm, during planting, soil is turned over, holes are dug according to the row spacing of about 33 cm, each hole is subjected to cuttage with 1-2 cuttings, two sections at the top end need to be exposed out of the soil surface, and soil filling and pressing are conducted. The harm caused by kiwifruit canker and root-knot nematode disease is avoided.

Description

technical field [0001] The invention relates to the technical field of kiwifruit propagation, in particular to a method for rootstock grafting kiwifruit. Background technique [0002] Kiwi fruit is native to my country and has been cultivated for more than 1,300 years. Today, China is a veritable big country of kiwi fruit production. The development of fruit processing enterprises is thriving, the modern circulation mode is gradually improved, and the trade is active. The top three kiwi fruit production in the world: No.1 China; No.2 Italy; No.3 New Zealand. More than half of the world's production is produced, and most of the red kiwifruit is planted in China. [0003] Grafting propagation is the main propagation method of kiwifruit varieties. The difficulty of grafting and survival and the suitable stock and ear combination are the main factors affecting the breeding of fine kiwifruit varieties, which directly affect the popularization and application of fine kiwifruit vari...
