[0003] Patent CN 102295480 A relates to a nutrient solution and a cultivation method for aeroponic cultivation of potato miniature seed potatoes in a greenhouse. This patent focuses on the nutrient solution and simple cultivation steps of potato miniature seed potatoes, but ignores the cleaning and maintenance of the aeroponic device before planting. Disinfection and the prevention and control of potato diseases and insect pests during the cultivation process can easily lead to a large outbreak of diseases and lead to production failure, and the patent directly uses the test tube seedlings to harden the seedlings and then carry out the fog culture planting without the treatment of strong seedlings. low rate
[0004] CN 103159528 A patent relates to a nutrient solution and method for aeroponic production of original potato seeds. The aeroponic planting method for potatoes includes hydroponic strong seedlings and pest control. It is cumbersome, the aseptic treatment of nutrient solution is difficult, and the possibility of infection by diseases and insect pests is very high in the high humidity of the seedling tray; Fungicides and pesticides are used to prevent and control diseases, which not only increases the cost of planting, pollutes the environment, but also greatly affects the safe edible value of potatoes. It is not suitable for family planting for the purpose of edible potato chips

Embodiment 1

[0070] Cultivated Variety: Gui Nong Shu No. 1

[0071] 1. Preparation of nutrient solution

[0072] Combined with the growth characteristics of potatoes, the entire cultivation process is divided into three stages, and corresponding nutrient solution is added at each stage. The nutrient solution contains three major elements of nitrogen, phosphorus and potassium and various medium and trace elements. , respectively prepared into four kinds of mother liquors A, B, C and D for sealed packaging. The contents of each mother liquor are shown in Table 3, and the storage period is one month; nutrient solution. When preparing the full-concentration fog culture nutrient solution, the dilution factor of A, B and C mother solutions is 100 times, and the dilution factor of D mother solution is 1000 times; The multiple is 200 times, and the dilution factor of D mother solution is 2000 times.

[0073] Table 3 Components and concentrations of A, B, C and D mother liquors in the three stag...

Embodiment 2

[0098] Guicaishu No. 1 was used as the implementation variety, and the same method as in Example 1 was used for aeroponic planting. The formula of the three-stage nutrient solution and mother solution is shown in Table 4.

[0099] Table 4 Components and concentrations of the three stages A, B, C and D mother liquors of Guicaishu No. 1 produced by home aeroponic culture

[0100]

[0101] Guicaishu No. 1 is a medium-maturing colored potato variety. It takes 22 days for the tissue culture seedlings to grow and then carry out hydroponics to strengthen the seedlings. Change the formula of the nutrient solution. 71 days after transplanting, some potato pieces have reached more than 5g, and harvesting can be started in batches. After the start of harvest, picking can be continued for 39 days. The average potato formation rate per plant is 25.2 grains / plant, and the average fresh potato weight is 7.1g / plant. grain. After the potato pieces are harvested, clean the aeroponic facili...

Embodiment 3

[0103] Taking Guicaishu No. 1 as the implementation variety, the same method as in Example 1 was used for aeroponic planting. The difference between the three-stage nutrient solution and Example 1 is that the concentration of each component in the A and B mother solutions is different. See the table for details. 5.

[0104] Table 5 Components and concentrations of the three stages A, B, C and D mother liquors of Guicaishu No. 1 produced by home aeroponic culture

[0105]

[0106] It takes 22 days for the growth of the tissue culture seedlings to carry out hydroponics to strengthen the seedlings. After 15 days of hydroponic growth, it is transplanted and planted in aeroponic culture. After 32 days after planting, it enters the mid-growth stage, and the seedlings are pulled and the nutrient solution formula is replaced. 72 days after transplanting, some potato pieces have reached more than 5g, and harvesting can be started in batches. After harvesting, the picking can be cont...

Abstract

The invention belongs to the technical field of agriculture and provides a nutrient solution for household aeroponic-culture potato production. The culture process is divided into three stages according to the growth features of potatoes, and the corresponding nutrient solution is added to each stage. The nutrient solution comprises mother solutions A, B, C and D, and the mother solutions are diluted by water during use. The invention further provides a method for household aeroponic-culture potato production. The method aiming at the features of household small-scale potato production includes: providing healthy seedlings, preparation before seedling planting, planting aeroponic-culture seedlings, potato growth management, disease and pest management, batch harvesting, and the like. The method is convenient to use, high in efficiency and low in cost, automatic management is achieved, disease control is performed through ultraviolet lamp sterilizing, and environment-friendly and nutrient household potato planting is achieved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a nutrient solution and a method for producing potatoes by household aeroponic cultivation. Background technique [0002] The current technology is mainly aimed at the nutrient solution or device for the large-scale production of miniature seed potatoes by greenhouse potato aeroculture and the supporting cultivation methods. It is designed for the purpose of large-scale production of potato miniature seed potatoes in greenhouses. The process is cumbersome, the operation is complicated, etc., and there is no small-scale aeroponic potato production device or cultivation method for the purpose of family leisure agriculture, and it is difficult to use it for small-scale family planting. Because the environment of family cultivation is different, targeted methods should be adopted for the cultivation devices and cultivation methods of small-scale household aeroponic potatoes, so as ...
