Description

Technical Field

[0001] The invention belongs to the field of plant asexual reproduction, and in particular relates to a highly efficient cutting seedling raising method for money tree and a one-step production process for small potted plants. Background Art

[0002] Asexual reproduction is an important method for many horticultural crops and agricultural crops to cultivate seedlings. The main methods of asexual reproduction include grafting and cuttings. Plant cuttings are commonly used for woody plants and some perennial plants. In most cases, cuttings are used for branches with buds (cuttings), and cuttings are also used for organs such as leaves. After rooting and sprouting, they are cultivated as seedlings. Money Tree ( Zamioculcas zamiifolia ) is a perennial herb of the Araceae family and an excellent tropical foliage plant. The current method of propagating seedlings in production is to use small leaf cuttings or leaf axes with leaflets to form tubers from the cut at the base of the small leaf cuttings, and buds differentiate in the tubers to grow into seedlings.

[0003] At present, in the cutting method, generally each cutting forms a tuber and grows a seedling at the incision, and the reproduction coefficient is as low as 1. In production, a large number of small leaves are needed as cuttings, and more potted plants are needed as parents of the cuttings. This cutting technology is mainly based on the new discovery of regeneration characteristics. It is found that the cutting regeneration of money tree is a de novo regeneration method, that is, regeneration from cells rather than buds. Cells restore the ability to divide to form tissues and differentiate to form tubers. The formation of tubers is always related to conductive tissues and originates from cells around conductive tissues. After technical treatment, it can promote the formation of multiple tubers, significantly improve the cutting reproduction coefficient, improve reproduction efficiency, and reduce production costs. Summary of the invention

[0004] The present invention provides a money tree efficient cutting seedling raising method and a small potted one-step production process, so as to solve the drawback of low regeneration efficiency in the existing money tree cutting seedling raising technology in the field of plant cutting propagation. On the one hand, the previous cutting processing method usually directly uses a large number of complete small leaves for cutting, which consumes a considerable amount of leaf materials, has a high cost of raw materials, and the labor hours invested in the process of picking and arranging these leaves are relatively long, and the labor cost is also relatively high in the city, and the cutting site demand is relatively large, and the land cost is relatively high. On the other hand, the reproduction efficiency of the existing cutting technology is low, and seedling propagation is difficult to meet the production demand for seedlings.

[0005] One embodiment of the present invention provides a method for efficiently raising seedlings of money tree by cuttings, comprising the following steps: Take mature leaflets from the compound leaves of the money tree and cut them longitudinally or transversely to form cuttings. When cutting longitudinally, cut the leaflets into 3 or more segments from the vertical plane of the main vein of the leaflets, and remove the petiole of the cut segments at the base of the leaflets; when cutting transversely, take the leaflets and cut them into two parts without the main vein along both sides of the main vein with a blade; the larger leaflets can be cut longitudinally in the middle to be divided into two parts, and after the cuttings are prepared, insert them into the prepared substrate for reproduction and seedling cultivation.

[0006] In one embodiment, the leaf veins and branches of each cut segment of the cutting are exposed at the incision.

[0007] In one embodiment, the prepared cuttings are inserted into a substrate vertically along the leaf veins for propagation and seedling cultivation.

[0008] In one embodiment, the substrate used is peat for seedling cultivation or a mixture of peat and perlite, and is disinfected with 500 times of carbendazim or thiophanate-methyl before use.

[0009] In one embodiment, the prepared cuttings are gently inserted into the substrate of the cutting pot, the insertion depth reaches more than 1 cm, the cuttings are spaced 3 cm apart, and water is sprayed after the cuttings to keep the substrate moist.

[0010] One embodiment of the present invention provides a one-step production process for small potted plants, comprising: A method for improving the efficiency of Zamioculcas zamiifolia cutting seedling raising as described in any of the above embodiments, and Production steps of small potted plants: Take 3 prepared cuttings and insert them into a flowerpot filled with cultivation medium, with the front side of the leaves facing the center of the pot. The 3 cuttings are triangular or circular in shape and inserted to a depth of more than 1 cm. The cuttings will form roots after 20 days, tubers after about 30 days, sprouts after 60 days, and small potted products after 90 days, thus realizing the one-step production of small potted plants.

[0011] The above technical solution provides a highly efficient cutting seedling raising method for money tree and a one-step production process for small potted plants, which has the following beneficial effects: 1. The traditional method uses a large number of intact leaflets as cuttings, while the unique cuttings processing method of this technology is to finely segment the leaves, such as cutting the leaflets horizontally into 3 sections, or to cut them horizontally, or to reasonably cut them according to the size of the leaves, so that each mature leaflet can be fully utilized; cutting the main vein can promote the cells near each leaf vein to resume division and regenerate more tubers. Compared with the existing cutting method, the demand for raw material leaflets is greatly reduced, thereby significantly saving a large number of leaflets used for cuttings and seedlings, directly reducing the procurement cost of the mother material. Through this cutting processing technology, a large number of leaflets used for cuttings and seedlings can be saved, reducing material costs, labor costs and land costs, etc. The cutting processing method can form more than 5-6 tubers per cutting, and the reproduction coefficient of each leaflet can be increased by more than 15-16 times.

[0012] 2. Since this technology improves the utilization rate and propagation efficiency of cuttings, the required cutting site area is greatly reduced under the same seedling raising goal. It is no longer necessary to place a large number of cutting containers on a large area, which reduces the dependence on land resources and saves land costs.

[0013] 3. The cuttings processing method provided by this technology fundamentally optimizes the structure and nutrient distribution pattern of the cuttings. After the cuttings are specially cut, the contact area between their parts and the matrix is ​​increased, which can absorb water and nutrients more efficiently and stimulate the rapid development of the root system. At the same time, reasonable segmented cutting retains the key leaf vein tissue, providing sufficient endogenous hormones and nutrients for the growth of the cuttings, thereby improving the reproduction coefficient. Through practical verification, this innovative cutting processing method can increase the reproduction coefficient of each cutting by more than 5-6 times. Based on 3-4 cuttings per small leaf, the reproduction efficiency can be increased by more than 15-16 times. A considerable number of seedlings can be cultivated in a short period of time, meeting the market's large demand for money tree seedlings and effectively promoting the large-scale development of the industry.

[0014] 4. This technology integrates the entire process from cutting preparation, cuttings to small potted cultivation, forming a one-step cultivation method, eliminating the intermediate links, making the entire production process more compact and efficient. The new process for small potted production can reduce production links, reduce production costs and shorten the production cycle.

[0015] 5. With the reduction of production links, the corresponding loss of manpower, material resources and financial resources in each link will also be reduced. For example, the operations of transporting cuttings and replacing cultivation containers are reduced, which avoids the extra labor and material consumption, greatly reduces the production cost and improves the cost performance and market competitiveness of the product.

[0016] 6. Based on the above-mentioned simplification and efficiency improvement, the entire production cycle is significantly shortened compared to traditional processes, from the initial insertion of cuttings into the substrate, to the formation of roots in 20 days, tuber formation in about 30 days, budding in 60 days, and the formation of small potted plants that can be sold on the market after 90 days. This not only speeds up the recovery of funds, but also enables products to be put on the market more promptly, seize opportunities, and meet consumers' timely demand for fresh green potted plants.
