Off-season white radish mainly refers to white radish cultivated in spring and summer. It has a good market base, and the demand is large, and the price is relatively high. The following will analyze the cultivation techniques of white radish in combination with the actual situation. In order to improve the experience for future related work.
1 anti-season white radish cultivation technology
1.1 Selection
Seed selection is an important part of the cultivation process of off-season white radish. When planting in spring, try to choose white radish varieties with better cold resistance and strong convulsion resistance. Due to the low temperature in spring, if the varieties that do not have strong cold tolerance are selected during the cultivation and cultivation, it is very likely to cause the reduction of white radish, and it will seriously affect the quality of white radish and cause certain economic losses to the growers. . In the summer season, the anti-season radish cultivation process should select varieties with high heat resistance, strong disease resistance and high yield, such as white autumn Mino, white jade king, etc., not only beautiful appearance, less roots, and fleshy roots. The diameter is 6~6.5cm, and the disease resistance is strong, so as to prevent the production in the process of cultivation and planting, and reduce the impact on economic benefits as much as possible.
1.2 Cultivation
In the spring radish cultivation process, the planting time can be arranged reasonably according to the different planting methods. If the greenhouse cultivation method is adopted, the cultivation time should be controlled in the first half of February, and the planting time of the decanter in the spring greenhouse is controlled from the end of February to 3 At the beginning of the month, the spring mulch cover cultivation should be controlled as much as possible on April 5-10; in summer, white radish should be cultivated from the end of June to the beginning of July. Because the radish root of white radish is long, deep arable land is needed, and the fertile sandy loam is used as the best planting soil. Before planting, the soil preparation and loose soil should be fully prepared, and the gravel existing in the soil should be removed. Clay, hard objects, etc., create good conditions for the growth of white radish. After the completion of the land preparation, the problem of fertilization should be fully considered, and high-quality decomposed organic fertilizer should be used as the base fertilizer to ensure that the white radish seedlings can absorb enough nutrients during the initial growth process. In addition, attention should be paid to the proper irrigation of the growth of white radish to prevent excessive water from seriously affecting the growth of white radish.
1.3 Field management
After the cultivation of white radish, the cultivation area of ​​white radish should be managed according to the actual situation. In the spring field management, the issues of heat preservation, cold protection, and convulsion prevention should be fully considered to ensure the emergence rate of white radish. The bottom water should be poured during sowing, so that the seedlings can fully absorb water during the growth process to enhance emergence. Rate, in the presence of two or three true leaves, the first seedling should be carried out, shallow cultivating, in order to achieve the purpose of controlling weeds and increasing surface temperature. When the white radish grows until the fleshy root begins to expand, the white radish can be properly irrigated in combination with the actual weather conditions, and urea is applied with 225 kg·hm of urea and 45 kg·hm of potassium fertilizer to ensure sufficient nutrients for the growth of white radish. In the summer, due to factors such as heat resistance, pest resistance, and flood control, drainage ditch should be set up in the field to prevent the occurrence of waterlogging disasters in summer and rainy days. Growers should plant as much as possible in fine weather. Watering should be done sooner or later after emergence. Follow the principle of timely and proper amount. At the same time, reference well water to reduce surface temperature to change the local environment in the planting area to reduce high temperature weather on white radish. The effect of growth, combined with the actual situation, appropriate topdressing, to ensure that the white radish has sufficient nutrients during the growth process.
2 Pest control
In the spring cultivation of white radish, attention should be paid to the control of the growth of white radish by aphids, larvae and other pests. In order to effectively solve the problem of white radish pests and diseases, it is possible to spray the medicinal herbs such as suiwei and Jiqi worm, while the summer cultivation is based on the control of aphids and larvae, and also to control the cultivation of white radish by cabbage worms, noctuids and other pests. The effect can be controlled by using Baicao No.1 and Baidoujing. In addition, the prevention and treatment of diseases is also an important issue that needs to be considered during the cultivation of white radish in the off-season. Under normal circumstances, soft rot, black rot, and viral diseases are diseases that are more likely to occur in white radish, and can be controlled in the following ways.
1) Strengthen the field management of the white radish area. In the planting process, combine the actual conditions in the planting area, rationally irrigate and fertilize, remove the aphids and weeds in the field, and use high-quality organic fertilizer as the base fertilizer, combined with the growth of white radish. Appropriate nitrogen fertilizer is added.
2) In the process of field management, once the diseased plants are found, they should be removed in time, and lime is used for disinfection to prevent further spread of the disease.
3) When controlling soft rot, you can use Nongkang 751, seed dressing according to the weight of white radish seeds, 1%~1.5%, or use fengluling to seed 750 g·hm to achieve the purpose of preventing soft rot. In the early stage of the disease, white radish seedlings can be sprayed on the diseased plants with a liquidity of 72% of agricultural streptomycin sulfate from 3,000 to 4,000 times.
4) In the prevention and treatment of black rot, you can use Fumi double powder to mix seeds. In the early stage of the disease, you can also use 72% agricultural streptomycin sulfate to spray 3000~4000 times liquid on the diseased plants, or use Fengling 200 times. The liquid is sprayed once every 7~10d, and the number of spraying is determined according to the condition of the white radish to achieve the purpose of preventing black rot.
3 Conclusion
The continuous development of planting techniques in China has promoted the improvement of the cultivation technology of white radish in the off-season. Because of the good development prospects of the anti-season white radish, and the large market demand, it can obtain better economic value, which is favored by the majority of growers. However, in the cultivation process, the lack of professional cultivation techniques caused the growers to reduce the yield during the cultivation process, which reduced the economic benefits to some extent. Therefore, in the future cultivation process, growers should actively learn cultivation techniques, and use scientific and reasonable methods to deworm when white radish is found to ensure the quality and yield of white radish and effectively improve economic benefits.
The above is the high-yield cultivation techniques of off-season white radish. Welcome everyone to come to Huinong.com to learn more!
