Problems solved by technology

At present, vermiculite is mainly used as the cultivation substrate for the original seed of virus-free potato (see: Wang Yi. Greenhouse Soilless Cultivation Production of Potato Microtuber Technology [J]. Qinghai Agricultural Technology Extension, 2014 (3).), because vermiculite is A kind of ore resources, its resources are limited, and the production process is complex, and repeated use must be returned to the furnace for high-temperature calcination and disinfection, so the price is expensive
When vermiculite is used as the cultivation medium of the original seed of detoxified potato, because of its fragility, with the prolongation of the use time, it is easy to make the medium dense and lose the air permeability and water retention, resulting in serious late blight; vermiculite only has water retention , does not have nutritional function, and nutrient solution needs to be supplemented in production to meet the growth needs of the original seed of the virus-free potato, which increases the production cost, and the yield and quality of the original seed of the virus-free potato are also greatly affected. Popularization and Application of Soil Cultivation

Embodiment 1

[0031]Select 6 substrate grooves, be divided into 2 groups, repeat 3 times in every group, the first group adopts conventional substrate cultivation (vermiculite), and the method used adopts the method recorded in the prior art (Wang Yi. Greenhouse soilless cultivation produces potato miniature Potato Technology[J]. Qinghai Agricultural Technology Extension, 2014(3).). The second group adopts the seedling soilless cultivation method of the present invention to measure the yield per mu and the commodity rate of two groups of potatoes, and the results are as shown in Table 1.

[0032] Table 1

[0033]

[0034] According to the analysis of yield per mu and rate of commercial potato, it can be seen that the yield and commercial potato are significantly improved by adopting the seedling soilless cultivation method of the present invention, and the method of the present invention can produce significant economic benefits.

Embodiment 2

[0036] Select 6 substrate grooves, be divided into 2 groups, repeat 3 times in every group, the first group adopts conventional substrate cultivation (vermiculite), and the method used adopts the method recorded in the prior art (Wang Yi. Greenhouse soilless cultivation produces potato miniature Potato Technology[J]. Qinghai Agricultural Technology Extension, 2014(3).). The second group adopts the seedling soilless cultivation method of the present invention to measure the tuber quality indexes of two groups of potatoes, including starch content, soluble sugar content, Vc content, and protein content. The results are shown in Table 2.

[0037] Table 2

[0038]

[0039]

[0040] From the above data analysis, it can be known that the soilless cultivation method for seedlings of the present invention can greatly improve the yield and quality of potatoes compared with conventional substrate cultivation.

Embodiment 3

[0042] Select 6 substrate grooves, be divided into 2 groups, repeat 3 times in every group, the first group adopts conventional substrate cultivation (vermiculite), and the method used adopts the method recorded in the prior art (Wang Yi. Greenhouse soilless cultivation produces potato miniature Potato Technology[J]. Qinghai Agricultural Technology Extension, 2014(3).). The second group adopted the seedling soilless cultivation method of the present invention, and counted the survival rate of the seedlings one week after the seedlings were transplanted.

[0043] table 3

[0044]

[0045] From the above data analysis, it can be known that the seedling soilless cultivation method provided by the present invention can significantly improve the seedling survival rate, indicating that the cultivation method can make the root system of the seedling fully contact with the substrate, which is not only suitable for rooting, but also suitable for the growth and development of the roo...

Abstract

The invention belongs to the field of agriculture cultivation, and particularly relates to a soilless culture method for potato seedlings. Local agricultural wastes mostly existing in the Inner Mongolia are used, and the seedling soilless culture method is make according to the actual conditions of local potato planting and is suitable for seedling growth, low in cost and simple in step; limits to soil cultivation are removed, the cultivation field of potatoes is enlarged, factory-like and automation development of potatoes are promoted better and faster, and the method has wider market prospects and higher application value.

Description

technical field [0001] The invention belongs to the field of agricultural cultivation, and in particular relates to a soilless cultivation method for potato seedlings. technical background [0002] Potato is not only a vegetable but also a food, and it is also a good feed for the development of animal husbandry. In addition, the potato is also one of the indispensable and important raw materials in the food industry, pharmaceutical manufacturing industry and light industry. In the traditional method of asexual reproduction using potato tubers, due to factors such as virus infection and plant aging, the seed potatoes will degenerate and lose their use value. Therefore, the use of detoxification technology to produce qualified detoxified seedlings is the basis for ensuring stable and efficient potato production. Detoxified seedlings are generally produced by detoxified test tube seedlings obtained by stem tip stripping culture. The main methods are substrate cultivation and ae...
