Embodiment 1

[0039] The planting method of potato virus-free cuttings includes the following steps:

[0040] 1 Preparation of planting substrate for potato cuttings

[0041] A 20cm thick river sand with a particle size of 1mm was laid on the seedbed as a substrate. Water thoroughly and prepare for planting when the water content reaches 70%.

[0042] 2 transplanting

[0043] 2.1 The robust (height: 7 cm, about 0.1 cm in diameter) potato cuttings that have been propagated in the tissue culture room were selected and transplanted into a warm net shed in a cloudy day.

[0044] 2.2 Plant 250 plants per square meter. When cutting, make the root system fully contact with the substrate, and spray water in time.

[0045] 2.3 Seedling stage management

[0046] 2.4.1 After the cuttings are transplanted, they should be covered with plastic film and shading mesh, and the film should be gradually removed after 10 days of slowing down the seedlings, and the shading mesh should be removed 40 days af...

Embodiment 2

[0081] The planting method of potato virus-free cuttings includes the following steps:

[0082] 1 Preparation of planting substrate for potato cuttings

[0083] A 20cm thick river sand with a particle size of 0.5mm was laid on the seedbed as the substrate. Water thoroughly and prepare to plant seedlings when the water content reaches 60%.

[0084] 2 transplanting

[0085] 2.1 The robust (height: 6 cm, diameter of about 0.1 cm.) potato cuttings that have been propagated in the tissue culture room were selected and transplanted into a warm net shed in a cloudy day.

[0086] 2.2 Plant 200 plants per square meter. When cutting, make the root system fully contact with the substrate, and spray water in time.

[0087] 2.3 Seedling stage management

[0088] 2.4.1 After the cuttings are transplanted, they should be covered with plastic film and shading mesh, and the film should be gradually removed after 7 days of slowing down the seedlings, and the shading mesh should be removed ...

Embodiment 3

[0123] The planting method of potato virus-free cuttings includes the following steps:

[0124] 1 Preparation of planting substrate for potato cuttings

[0125] A 20cm thick river sand with a particle size of 0.6mm was laid on the seedbed as the substrate. Water thoroughly and prepare for planting when the water content reaches 65%.

[0126] 2 transplanting

[0127] 2.1 The robust (height: 6.5 cm, about 0.1 cm in diameter) potato cuttings that have been propagated in the tissue culture room were selected and transplanted to a warm net shed in a seedling-raising medium on a cloudy day.

[0128] 2.2 Plant 200 to 250 plants per square meter. When cutting, make the root system fully contact with the substrate, and spray water in time.

[0129] 2.3 Seedling stage management

[0130] 2.4.1 After the cuttings are transplanted, they should be covered with plastic film and shading mesh, and the film should be gradually removed after 8 days of slowing down the seedlings, and the sh...

Abstract

The invention discloses a virus-free potato cutting seedling planting method. The method at least comprises steps as follows: 1) a 20 cm thick substrate is paved with river sand with the size of 0.5-1mm on a seedling bed, virus-free potato cutting seedlings are transplanted, and root systems of the virus-free potato cutting seedlings are buried into the substrate; 2) after transplantation, the cutting seedlings are covered with a plastic film and a sunshade gauze, the plastic film is removed step by step after the seedlings recover for 7-10 days and the cutting seedlings grow new roots in thesubstrate, and the sunshade gauze is removed after 30-40 days of transplantation; 3) water-soluble mixed fertilizer is applied after 9-11 days of transplantation; and 4) after the potato fruiting period begins, the maximum water-holding capacity of the substrate is controlled at 75%-80%, the temperature of the growth environment is controlled at 17 DEGC-25 DEGC, and diseases, insect pest and weeds are controlled on the potatoes in the whole growth process. According to the method, the river sand is paved on the seedling bed to serve as the substrate, the roots of the cutting seedlings are buried in the substrate layer, and virus infection in the growth process of the cutting seedlings is effectively reduced.

Description

technical field [0001] The application relates to a method for planting potato virus-free cutting seedlings, belonging to the technical field of harvesting, selecting, processing and quality testing of new crops, forage grass and forest tree seeds. Background technique [0002] Potato is an annual herb of the Solanaceae family with edible tubers and is the fourth most important food crop in the world. The common propagation method is to take advantage of the germination characteristics of tubers, select healthy potatoes, cut them into pieces with a knife, and plant them in the soil. Asexual reproduction. [0003] This method of reproduction is prone to degeneration of potatoes, which is mainly due to the intergenerational transmission of viral infections. In order to reduce the intergenerational transmission of stem tuber virus, the bud tissue is often cultured after the shoot tip is isolated to obtain potato virus-free cutting seedlings. Subsequent virus detection, transp...
