Description

An aerial continuous potato forming device for separation and cultivation of sweet potato root functions

technical field

The utility model relates to crop cultivation equipment, in particular to an aerial continuous potato forming device for the separation and cultivation of sweet potato root system functions.

Background technique

At present, sweet potato is an important grain, vegetable, feed, industrial raw material and energy crop. Conventional cultivation uses stems and vines to grow on the ground, and the primary root system in the soil expands into tubers as the harvested product. The absorbing roots and tubers are mixed together. If you want to harvest tubers, you have to destroy the entire plant, so you can only harvest in a single stubble , A single plant cannot be harvested multiple times in a row. Sweet potato stems grow prostrate on the ground, but only occupy a space of about 30 cm near the ground, the land utilization rate is low, and the leaves block each other, the ventilation is poor, and the light efficiency is low. The above-mentioned defects have limited the improvement of the output of conventionally cultivated sweet potato, and have not fully brought into play the production potential of its output.

Utility model content

The utility model overcomes the above-mentioned shortcoming, and proposes an aerial continuous potato forming device for the separation and cultivation of sweet potato root system functions.

The technical scheme that the utility model solves its technical problem to take is:

An aerial continuous potato forming device for the separation and cultivation of sweet potato root system, which is provided with a nutrient solution pool, and a support is provided around and above the nutrient solution pool, and a number of pots are hung on the support. solid substrate.

The support is a steel pipe support, which is used to support the load bearing of sweet potato stems and leaves, tubers, pots and substrates.

The support is connected with the pot with a hanging rope.

The top of the nutrient solution pool is covered with a foam board to prevent sundries from falling into the pool, and it can also be used for shading, thermal insulation, and keeping the temperature of the nutrient solution relatively stable. The liquid supply pipe and the liquid return pipe provided on the nutrient solution pool can be used to control the liquid level of the nutrient solution to keep relatively stable, so as to avoid the root system of the sweet potato absorbing nutrients from lack of water and drying up, or the liquid level of the nutrient solution is too high, and the main stem of the sweet potato will be submerged for a long time Too long makes it rot.

The utility model has the advantages that it can induce adventitious roots on the stems and vines to expand and develop into sweet potato tubers, so as to realize continuous tuber formation in the air.

Detailed ways

Example 1

As shown in Figure 1, the sweet potato root system function separation cultivation aerial continuous potato planting device of the present utility model is provided with a nutrient solution pool 1, and a steel pipe support 5 is arranged around and above the nutrient solution pool 1, and several The pot 7 has a built-in solid matrix 8 for the growth of adventitious roots of sweet potato stems and vines. The nutrient solution pool 1 is provided with a liquid supply pipe 2 and a liquid return pipe 3 . The top of the nutrient solution pool 1 is covered with a foam board 4 . The steel pipe support 5 is connected with the pot 7 with a suspension rope 6 .

Nutrient solution pool 1 among the figure is a wooden structure, with an outer hoop iron ring and a plastic film inside to hold the nutrient solution. The liquid level of the nutrient solution is controlled by the liquid supply pipe 2 and the liquid return pipe 3 to keep it relatively stable, so as to prevent the sweet potato from absorbing nutrients from lack of water and drying out, or the liquid level of the nutrient solution is too high, and the main stem of the sweet potato is submerged for too long to make it rot . Foam board 4 is covered above the nutrient solution pool, which can prevent foreign matter from falling into the pool, and shading provides a dark environment for the root system. The steel pipe support 5 is used for climbing sweet potato stems and supporting the vertical and horizontal growth of sweet potato plants. The nutrient solution pool 1 is placed flat on the ground and does not go deep into the ground, so that the mobility of the device can be guaranteed, which is conducive to centralized production and display in different places. Every certain distance is tied with suspension rope 6 on the steel pipe support 5, is used for the connection of basin bowl 7 and steel pipe support 5, provides certain pulling force. The pot 7 is equipped with a solid matrix 8, and after the sweet potato vines are buried and pressed, adventitious roots on the vines will be induced to grow and expand into sweet potato tubers. When the tuber grows to a certain size, the solid matrix 8 in the pot can be emptied, and the pot 7 can be removed to obtain "sweet potatoes in the air". According to the growth conditions of sweet potato plants, multiple pots 7 can be placed continuously on the steel pipe support to induce the formation of multiple tubers and realize continuous potato formation in the air. The sweet potato stems, branches, leaves and even tubers are in the air, and the space under the device is left free for the production of other shade-tolerant plants or the production of vegetable seedlings, which greatly improves the space utilization rate.

When specifically cultivating, cuttages of sweet potato vines with a length of about 20 cm are planted in the nutrient solution pool 1, and the main stem enters two sections of water to grow absorption roots. After setting the value for about 3 days, new roots will emerge from the stem nodes of the sweet potato in the nutrient solution, and then the root system will grow vigorously but not expand. Two months after planting, the main stem will send out multiple branches. When the stems of each branch grow to about 1.5m, mix the solid matrix vermiculite, perlite, and peat 1:1:1 and put them into a 30cm diameter 1. In the pot 7 with a height of 40 cm, the vines are pressed one after another, and the 1-2 joints of sweet potato stems are buried in the solid matrix 8 in the pot 7 to induce the formation and expansion of adventitious roots. The used pot 7 of adorning solid matrix will guarantee certain size, too small is unfavorable for the expansion of tuber, and tuber shape is irregular; Too big waste matrix and space, investment increases. It is necessary to ensure that the root tubers are buried in the matrix throughout the growth period, and avoid cracking, germination, greening, lignification, etc. During root tuber growth, in order to ensure the wet state of solid substrate 8, the water content is kept between 30-70%, and regular watering or nutrient solution will be done every week. Two months after the vine pressing treatment, the sweet potatoes can be harvested according to the size of the potato pieces or the substrate and the pot 7 can be removed to display the sweet potatoes in the air. Since the harvesting of the tubers does not harm the primary root system (absorbing roots) of the sweet potato plant, the vines can be pressed multiple times and in multiple places, and the tubers can be harvested continuously. The sweet potato single plant of the present embodiment produces 358 kilograms of tubers, which shows a huge potential for increasing production.
