Problems solved by technology

The traditional split-root culture device is to fix the plants on a culture plate, and the incubator is divided into two parts with a partition, but the plant seedlings cannot be fixed well
However, the splitting method of splitting the main root of the plant is not only more harmful to the root system of the plant, but also not easy to distribute the roots evenly, resulting in a lower survival rate of the seedlings after splitting and poor test results.
At present, in the prior art, there has not been a plant root splitting soil culture device that can simultaneously fix the plant seedlings, divide the root system of the plant seedlings evenly, and do not damage the root system.

Embodiment 1

[0056] Such as figure 1 As shown, the present embodiment provides a kind of device that is used for the soil cultivation of plant split root, comprises incubator 1, dividing plate 2, planting hole 3, planting sponge 4, seepage hole 5; Described incubator 1 is 15mm by thickness Made of transparent plexiglass, the center is provided with a vertical partition 2; the top center of the partition 2 is provided with a planting hole 3, and the top is provided with a planting sponge 4 for fixing plant seedlings; the bottom of the incubator 1 There are 2 seepage holes 5 .

[0057] The incubator 1 can be disassembled and assembled. The sides of the incubator 1 are connected by screws, and the corresponding sides can be removed by opening the screws, which is conducive to direct observation of the root system and sampling of the root system, and facilitates the cleaning of the incubator 1.

[0058] Such as figure 2 As shown, the volume of the device is: length 390mm×width 29mm×height 3...

Embodiment 2

[0069] Application of the device described in Example 1 in the study of the effects of different nutrient supplies on plant root growth.

[0070] The application specifically includes the following steps:

[0071] 1. Pack air-dried low-phosphorus red loam of equal weight into several small boxes of incubator 1;

[0072] 2. Sprinkle with water to fully soak the soil in each small box;

[0073] 3. Take the annual sour orange seedlings whose size, growth and fibrous root quantity are basically the same, cut the main root length to 2.5cm and insert it in the planting hole 3, and the fibrous roots are divided into two parts on average and planted in two small boxes respectively for cultivation;

[0074] 4. Place a piece of planting sponge 4 around the seedlings, and wrap a layer of black film outside the incubator 1;

[0075] 5. Supply different nutrients to each small box in step 2, carry out routine water and disease and insect pest management to the plant seedlings, collect th...

Abstract

The invention belongs to the technical field of plant cultivation, and specifically discloses a device used for plant root-dividing soil cultivation. The device includes a cultivation box, partition plates, a field planting hole, a field planting sponge and water infiltration holes; the center of the cultivation box is provided with the plurality of vertical partition plates, and the partition plates divide the cultivation box into a plurality of uniform small boxes; the field planting hole is arranged in the intersection place of the plurality of partition plates, and the field planting sponge used for fixing plant seedlings is arranged on the field planting hole; and the bottom of the cultivation box is provided with the water infiltration holes. The device provided by the invention canbe applied to study on the influence of different nutrient supply on growth of plant root systems; the plant seedlings can be better fixed on the device, the root systems of the plant seedlings can beuniformly divided, the degree of damage of root dividing to the root systems of the seedlings is reduced, and the survival rate of the seedlings after root dividing is improved; and the device is simple and reasonable in arrangement, easy to operate, and suitable for a wide range of promotion and applications.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a device for root-divided soil cultivation of plants and its application. Background technique [0002] In nature, the nutrients in the soil usually exist in a non-uniform state in time and space distribution, and the heterogeneity of soil nutrients is mainly due to the uneven input of sedimentation, plant leaves and other organic substances and is decomposed by microorganisms in the soil. Produced in the long-term evolution process of nature. At the same time, in the farmland ecosystem, whether it is the sprinkler irrigation and drip irrigation in the integrated water and fertilizer technology, or the traditional methods of fertilization such as hole fertilization and furrow fertilization, all belong to local fertilization, which intensifies the heterogeneous distribution of nutrients in the soil, forming Nutrient patches. [0003] The water, nutrients and various en...
