Selectively planted
The pollution-free radish should focus on the selection of the land, and the source of the irrigation water should not be polluted. In addition, the radish has a wide adaptability to the soil, and the soil is required to be deep, water and drainage. Good sex and rich in organic matter. However, radish has higher requirements for land preparation. The field where the radish is grown should be cleaned and irrigated early after the harvest of the former crop, and the ploughed and ploughed must be 20-25 cm deep. After fertilizing and cultivating, make small stilts or small high ridges to prevent flooding. After the application of the fertilizer, the bulk bricks, tiles, glass, grass roots and waste plastic film are removed from the field to prevent the radish from splitting or cracking.
250-300 grams of radish seeds per acre of field, first mixed with 10-15 kg of fine soil and then spread evenly (the ridge cultivation can be carried out by hole or ditch), after the sowing cover soil is 1-1.5 cm thick, conditional The sunshade net should be covered to cool down and prevent rainstorms, so as to avoid the impact of seedlings due to heavy rain. The carrots are generally about 30 cm apart, and the hole spacing is 20-25 cm; the spring radish is 33 cm apart and the hole is 27 cm. If the weather is dry after sowing, it should be poured in small water, keep the ground moist, lower the ground temperature, and facilitate the emergence of seedlings. In case of heavy rain, it should be drained in time to prevent flooding. If the ridge is washed, it should be replanted in time after the rain.
Fertilization Technology
The base fat radish is generally used in live broadcast, so the base fertilizer is the main link of radish high yield. The base fertilizer can be applied to the decomposed (especially pay attention) 2500-3000 kg of manure, 10 kg of potassium sulfate, 25-30 kg of superphosphate, and turned into the soil. In some places, the base fertilizer can be used to apply soil fertilizer and apply a certain amount of cake fertilizer, so that the fleshy roots can be enriched, and it is not easy to be hollow during storage, which is conducive to the production of pollution-free radish.
For the first time, when the seedlings grow to the true leaves, 1000 kg of the decomposed thin human excrement is carried out. After the seedlings are fixed, the lean human waste is chased again. When the fleshy roots are broken, the fleshy roots are swollen and the growth begins. The third time, the concentration of 50% of the decomposed manure is 800-1500 kg and 5 Kilograms of superphosphate, 5 kg of potassium sulfate. The carrots are usually applied only three times. The spring radish can also be topdressed 1-2 times during the growth period of the fleshy roots. If the ground leaves are particularly thick green and strong, the top can not be topdressed, and 15% is needed. Spraying 50 grams of paclobutrazol with 50 kg of water inhibited the growth of the shoots and promoted the expansion of the underground fleshy roots.
If the nitrogen fertilizer is applied too much, the same air, the soil is dry, and the root is damaged, the absorption of calcium by the plant is hindered, the leaf edge is rotted, and the root surface has deep pores and many lateral roots and long symptoms. Therefore, in the later stage of radish growth, it is necessary to control the amount of nitrogen fertilizer, and at the same time pay attention to the supply of boron in the soil to prevent the radish from producing hollow and black hearts.
Field Management
Miao Ding Miao radish Qi Miao and 2-3 pieces of true leaf stage each time. When 4-5 pieces of true leaves are fixed, one seed is left in each hole.
Fertilizer management of radish is not only afraid of drought but also wet, and it is necessary to drain and reduce the rain when it rains for a long time. The radish leaves have a large area, strong transpiration, and poor drought resistance, and sufficient water should be supplied in a timely and appropriate amount. Before planting, it should be fully watered to ensure that the seedlings are quick and tidy; the seedling stage and the rosette period should be less watered, and the roots should be deepened into the soil layer to prevent the leaves from being long, and the masters should not be allowed to pour or the ground surface will be white. Principle; the root growth period should be fully uniform water supply, promote the expansion of meat roots, prevent hollowness, improve quality, and enhance storage capacity. Autumn cultivation is better with watering in the evening, which is beneficial to lowering soil temperature and promoting nutrient transport to the roots.
The principle of fertilization of radish is “mainly based on base fertilizer and supplemented by topdressing fertilizerâ€. The base fertilizer and short-lived varieties can be less topdressed. The long-term varieties should be topdressed and topdressed. The key point is to grasp the growth of radish and the growth of fleshy roots. The application of fertilizer.
The pests and diseases of pests and diseases are mainly aphids, locusts, cabbage caterpillars, yellow strips, beet armyworms, and viral diseases, black rots, etc. To make radishes harmless, the following points should be grasped. First, rational rotation, rational close planting, clean gardening, improve the microclimate environment in the field, and reduce the harm of diseases; second, the use of shade nets and insect net covering technology can reduce the occurrence of pests such as cabbage caterpillars, beet armyworms, etc. Pesticides, high-efficiency and low-toxic pesticides, adhere to the appropriate use of drugs, appropriate amount of medication. The fourth is the strict interval between medications, and the medication should be stopped 2 weeks before harvest.
Appropriate harvest in the radish fleshy roots fully expanded, when the leaf color turns light into yellow-green, it should be harvested in time. Try to get the early harvest as soon as possible, on the one hand, it can improve the economic benefits, on the other hand, it can avoid the worry caused by factors such as overexposure or drought.
If the radish grows in the planting environment and the product itself meets the requirements of “three products†(no pollution agricultural products, green food, organic food), the growers are willing to improve the grade of their radish, they can be related to the government. The department applies for “three productsâ€.
