Problems solved by technology

This method also has the following disadvantages: although the fruit quality of the scion variety is good, the fruit is large, and the yield is high, the general resistance is poorer than that of the rootstock, such as disease resistance, cold resistance, waterlogging resistance, and salt-alkaline resistance. Rootstock, poor adaptability

Embodiment 1

[0039] Embodiment 1, a kind of breeding method that improves fruit tree resistance, specifically as follows:

[0040] Implementation time: 2008-2012

[0041] Implementation location: Experimental Base of Fruit Tree and Flower Research Institute of Weifang Academy of Agricultural Sciences

[0042] Test materials: rootstock: Qingzhou peach, scion: 'Xiadan'

[0043] Test method steps:

[0044] In March 2008, the stratified Qingzhou peach seeds were sown and raised. The row spacing between plants is 10cm×30cm, four rows per row, and the row spacing is 60cm.

[0045] In mid-July, when the rootstock grows to 70cm, cut back, keep 50cm and carry out topping treatment to promote the rootstock to germinate multiple side branches.

[0046] 10 jin of urea and 5 jin of diammonium phosphate were applied per mu each time, three times in total, and watered 6 times. Start 30 days after the seeds germinate, fertilize once every 30 days or so, water immediately after fertilization, and wate...

Embodiment 2

[0051] Embodiment 2, the influence of grafting height on the survival rate of peach tree planting

[0052] Cultivate peach saplings according to the said method of embodiment 1, divide four heights, graft 'Xia Dan' with peaches from Qingzhou, the height is respectively 10cm above the ground; 30cm; After the treatment thickness reached 0.2cm, grafted 'Xiadan' respectively, 30 plants each, raised seedlings in autumn, and artificially planted, respectively selected 20 peach seedlings with good thickness and well-developed root system, and planted in our institute on March 20 in the spring of the following year The experimental base, the soil is sandy loam, flat land, good fertility, dig a 40cm wide, 40cm deep ditch, pour water immediately after planting, the row spacing is 100cm, the plant spacing is 50cm, after 3 days, the tree is covered with plastic film, and then no watering, no fertilization, The survival rate was counted after germination in the second spring, and the resul...

Embodiment 3

[0055] Embodiment 3, a kind of breeding method that improves fruit tree resistance, specifically as follows:

[0056] Implementation time: 2010-2014

[0057] Implementation location: Experimental Base of Fruit Tree and Flower Research Institute of Weifang Academy of Agricultural Sciences

[0058] Test materials: Rootstock: Xiaohuangli, Scion: 'Black Gem'

[0059] Test method steps:

[0060] In March, 2010, the layered rootstock seeds will be sown and seedling raised. The row spacing between plants is 10cm×15cm.

[0061] When the rootstock grows to 80cm, cut back, keep 60cm and carry out topping treatment, so as to promote the rootstock to germinate multiple side branches.

[0062] 10 jin of urea and 5 jin of diammonium phosphate were applied per mu each time, three times in total, and watered 6 times. Start 30 days after the seeds germinate, fertilize once every 30 days or so, water immediately after fertilization, and water every time at intervals of about 15-20 days, ju...

Abstract

The invention discloses a cultivation method for increasing the resistance of a fruit tree. The cultivation method comprises the steps of selecting a resistant rootstock, sowing seeds of the resistant rootstock, pinching for promoting the generation of branches of the rootstock when the rootstock grows to be 50cm-120cm long, grafting a needed variety on 2-6 branches according to the needs of a tree shape after the branches grow to a certain thickness which is suitable for grafting, meanwhile, cutting off main roots for promoting the generation and the growth of a large number of fibrous roots and fine roots through replanting again, and thus cultivating large fruit tree seedlings with branches and strong fibrous roots. According to the cultivation method disclosed by the invention, not only is the advantage of strong resistance of an underground part of the rootstock utilized, but also the advantage of strong resistance of an overground part of the rootstock is utilized, the increase of the whole resistance of the fruit tree is promoted, the resistance is enhanced after nursery stocks of the fruit tree are planted, the fruit tree can bear fruits in 2-3 years, and the fruiting period of the fruit tree is greatly quickened.

Description

technical field [0001] The invention relates to a cultivation method for improving the resistance of fruit trees. The method is suitable for cultivating large seedlings of fruit trees with branches, especially suitable for the situation that the growth speed of the rootstock is higher than or close to that of the grafted variety, and is not suitable for the growth speed of the rootstock than the grafted variety. If the varieties are slow, such as grafting peaches and apricots with various hairy cherries and plums, and grafting apples with dwarfed apples (M7, M9, MM106). This method is particularly suitable for shaping fruit trees without a center stem. After planting, the resistance of the tree was significantly improved. This embodiment is particularly suitable for increasing fruit trees' drought resistance, salt-alkali resistance, disease resistance, quality improvement, flowering period, maturity period and other characteristics. Background technique [0002] At present...
