In order to compare the effects of the konjak cultivation medium provided by the invention, the same batch of konjak seeds are selected and planted by the cultivation medium prepared by the 4 examples and the common cultivation medium respectively, and the following table shows the corresponding konjak disease rate comparison data:

	disease rate of konjak
		Culture substrate prepared in example 1	3.7％
Example 2 cultivation substrate	4.6％
		Example 3 cultivation substrate	4.0％
Example 4 cultivation substrate	3.5％
		Common culture medium	17％

According to the data in the table, the disease rate of the konjak planted by using the konjak cultivation substrate provided by the invention is less than 5%, and is far lower than that of the konjak planted by using a common cultivation substrate.

There is also provided in this example embodiment a cultivation system of konjak, including: cultivation frame, a plurality of field planting container and intelligent irrigation equipment that have preset size. The cultivation frame is arranged in the greenhouse; a plurality of planting containers with preset sizes are placed on the cultivation frame; wherein, each planting container is filled with the culture medium prepared in any one of the embodiments, and konjak seeds are planted in each planting container; the intelligent irrigation equipment is connected with the plurality of planting containers through pipelines and used for determining water and nutrient parameters required by each growth period of the konjak so as to supply water and nutrient solution to each planting container.

By the cultivation system, factory three-dimensional production can be realized in a facility environment, the land is not required to be turned over and changed, no intertillage and weeding are required, soil-borne diseases and the influence of extreme environment are avoided, and high efficiency, labor saving and high quality are achieved.

In one embodiment, the cultivation shelf comprises a trapezoidal support frame and a cross arm arranged on the support frame. Wherein, the both sides of trapezoidal support frame are equipped with two bracing pieces respectively and are used for fixed cross arm. In specific example, trapezoidal support frame can select for use 2x 4's galvanized square pipe welding to form, for example, trapezoidal support frame's the wide 1 meter in end, the wide 0.2 meter in top, the height is 1.5 meters, the bracing piece of both sides outwards extends 0.25 meters, and the cross arm can be made with 10# round steel bar welding two for putting the field planting container.

In the process of building the cultivation frame, a trapezoidal support frame is usually arranged every two meters, the number of the whole trapezoidal support frames can be increased or decreased according to production requirements, and the cross arms are arranged in three rows from top to bottom. Due to the special structure of the trapezoidal support frame, the planting containers placed on the upper and lower three rows of cross arms cannot be shielded from each other, and the growth of the konjac is facilitated.

In one embodiment, the konjac seeds planted in the cultivation system include both commercial konjac seeds and seed taro seeds. Wherein, commercial taro seeds are planted in the planting container in a single plant, and 4-6 taro seeds are planted in the planting container. The commercial taro is the konjac which is planted in the current year and sold in the current year, the disease spreading can not be caused by single plant planting, if diseased plants exist, the diseased plants can be taken out of a production area along with bag removal for treatment, and particularly, the konjac and the taro penis with seeds can not be infected with germs due to injury. But also has convenient harvest and is not easy to cause mechanical damage. Specifically, the planting containers for planting the commercial taro seeds can be placed on the two rows of cross arms, and the planting containers for planting the taro seeds can be placed on the lowest row of cross arms. Thus, the three-dimensional cultivation has good ventilation and air permeability, is beneficial to the growth of each konjac seed, and fully utilizes the space.

In one example, the planting receptacle may be cylindrical, with predetermined dimensions, specifically a bottom diameter of about 25-35 cm and a height of 35 cm. Because the root of the konjak can expand by 8-10 times in the growth process, the growth of the konjak is not utilized when the constant value container is too small, and the space is wasted when the constant value container is too large. For example, the planting container is a cylindrical non-woven bag, the bottom surface of the non-woven bag is 30 cm in diameter and 35 cm in height.

In one embodiment, a humidity sensor is arranged in at least one planting container, and each humidity sensor is electrically connected with intelligent irrigation equipment. Specifically, the planting container can be divided into a plurality of areas according to the position, one planting container is selected in each area, and the humidity sensor is placed in each area. The humidity sensor is used for sensing the humidity of the culture medium in the constant value container and transmitting data to the control center of the intelligent irrigation equipment. In the subsequent process, the control center irrigates the konjac in the area constant value container according to the received humidity data.

Specifically, each irrigation transmission pipeline adopts a PE pipe, a main pipe 50# and branch pipes 20#, and one-in two-out drip arrow is arranged on each branch pipe, so that each planting container corresponds to one drip arrow and is used for supplementing water and nutrient solution. Therefore, accurate irrigation and wetting without waterlogging can be achieved, and the venturi nutrition supplement system is installed in the liquid supply main pipeline, so that nutrient solution can be supplemented according to the growth condition of the konjak, and the konjak does not need chemical fertilizer and pesticide in the whole growth process.

In the rooting and sprouting stage of the konjak, the humidity of the culture medium is kept between 30 and 40 percent; in the period of replacing the head and expanding the konjac, the humidity of the culture medium is kept at 70% -80%, and nutrient solution is supplemented. Wherein, the nutrient solution can be 1300-1600 times of potassium fulvate and 400-600 times of algin; and in the later stage of konjak growth, keeping the humidity of the culture medium at 60%.

In one embodiment, the cultivation system further comprises a temperature control device arranged in the greenhouse and used for keeping the growth temperature at 28-32 ℃ in the rooting and sprouting stage of the konjak; in the head-changing and expanding period of the konjak, the growth temperature is kept at 25-35 ℃; and in the later growth stage of the konjak, keeping the growth temperature at 25-35 ℃.

In addition, the cultivation system can further comprise a sterilization device for sterilizing the environment in the greenhouse, and specifically, the sterilization device can be a strong magnetic electrostatic generator.

The konjak cultivation system provided by the example is shown in fig. 2, so that artificial intelligent and three-dimensional intensive production of konjak is realized, and compared with the traditional planting, the yield of a greenhouse for one mu can be increased by 2-3 times. And the konjak is cultivated by using the system without stubble ploughing and rotation, so that the disease spread is reduced, the soil utilization rate is improved, and the labor cost is reduced.
