Description

Technical Field

[0001] The invention relates to the technical field of agriculture, and in particular to a method for preserving and raising taro seeds and seedlings. Background Art

[0002] Taro, scientifically known as Colocasia esculenta, belongs to the genus Colocasia of the Araceae family. It is famous for its rhizomes that are rich in starch and crude protein. Taro not only contains these main nutrients, but also contains a variety of vitamins, amino acids, and trace elements that are beneficial to the human body. It is a food with high nutritional value and is deeply loved by people. In agricultural cultivation, taro cultivation technology is also constantly developing, but it still faces some challenges.

[0003] The traditional method of growing taro requires that the young taro be stored in a cellar after harvest. Although this method can maintain the freshness and germination ability of the taro, it also brings a series of problems. The construction and maintenance of the cellar requires additional labor and cost, and the temperature and humidity control requirements of the environment are high. The slightest carelessness may cause the taro to rot or germinate poorly. In addition, the cellar storage method is becoming less and less economical as labor costs are rising. Farmers need to invest a lot of time and energy to transport, store and take out the young taro. These repetitive and labor-intensive tasks are not only inefficient, but also increase the cost of planting.

[0004] With the development of modern agricultural technology, taro planting technology is also moving towards mechanization and efficiency. Although the development of taro mechanization technology is still in its infancy, future taro planting robots are expected to improve economic and social benefits in a more efficient way. The development of these technologies will help reduce labor demand, reduce planting costs, and improve taro yield and quality.

[0005] Chinese patent CNCN111096206A discloses a cultivation method that overcomes the obstacle of continuous cropping of taro. This method targets a common problem in taro planting, that is, continuous planting of taro on the same land will lead to an imbalance of soil nutrients and an increase in diseases, thereby affecting the yield and quality of taro. This patented technology effectively improves the yield of taro and mother taro by adjusting soil nutrition and reducing the occurrence of diseases, thereby enhancing the economic benefits of taro. However, this method does not solve the problems of low production efficiency and inability to ensure seed quality. Summary of the invention

[0006] The invention aims to provide a method for preserving and raising taro seeds, which can effectively improve the stability and reliability of taro seeds.

[0007] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0008] The invention provides a method for preserving taro seeds and raising seedlings, comprising the following steps:

[0009] Set up a ridge system in the seedbed, apply pesticides, plant the taro harvested that year as seed taro in the seedbed, and transplant the taro seedlings after they emerge from the soil.

[0010] Preferably, the ridge surface width of the ridge cultivation system is 100 to 140 cm;

[0011] The ridge surface height of the ridge cultivation system is 10 to 30 cm.

[0012] Preferably, the width of the inter-ridge ditches in the ridge farming system is 30 to 50 cm.

[0013] Preferably, the insecticide is selected from one or more of phoxim, verimer, chlorantraniliprole, chlorpyrifos emulsifiable concentrate, imidacloprid, lambda-cyhalothrin, mancozeb, avermectin, avermectin, pyraclostrobin or thiamethoxam.

[0014] Preferably, the application amount of the insecticide is 2 to 5 kg / mu.

[0015] Preferably, the planting row spacing is 5 to 15 cm.

[0016] Preferably, the planting spacing is 3 to 8 cm.

[0017] Preferably, the seed taro is covered with soil after being planted in the seedbed, and the thickness of the soil is 3 to 8 cm.

[0018] Preferably, the ridge surface is covered with crop residues after the soil covering.

[0019] Preferably, during the transplanting, the seedling height is 5 to 20 cm.

[0020] Beneficial effects of the present invention:

[0021] The present invention significantly improves the production efficiency of taro planting by directly carrying out seed preservation and seedling raising of taro taro in the field. This method avoids the cumbersome taro taro handling and storage steps in the traditional method, thereby reducing the dependence on labor and reducing labor costs. At the same time, since the taro taro is directly preserved in the field, the seed loss caused by improper cellar environment is reduced, and the preservation quality of the seed is improved, which is very important for the stability and reliability of taro planting.

[0022] In addition, the present invention also takes into account the influence of environmental factors on the growth of taro, and selects to transplant seedlings when the climate is suitable, which not only improves the environmental adaptability of seedlings, but also helps to improve the growth quality and yield of taro. By reducing unnecessary handling and storage steps, the present invention also helps to reduce energy consumption and reduce the impact on the environment, which is in line with the development trend of green agriculture.

[0023] In terms of economic benefits, the present invention effectively improves the production efficiency of taro and reduces the cost by saving labor costs and reducing seed losses. This is of great significance for improving the overall competitiveness of the taro industry and promoting the sustainable development of the industry. In general, the present invention not only optimizes the planting process of taro, but also brings actual economic benefits to taro growers by improving efficiency and reducing costs, and also contributes to environmental protection.
