It is not only sweet and crisp, but also sweet and crisp. This film focuses on the plant morphological characteristics, quality and nutritional growth habits, variety requirements, cultivation sites, plug selection, matrix requirements, management requirements during emergence, seedling stage management, and final mature harvest of Cherry Radish.

Cherry Radish plant height of 20-25 cm, fleshy root round, diameter of 2-3 cm, root skin red, flesh white, single root weight of 15-20 g, tender quality, refreshing and delicious. Can be raw food, cold mix, but also with vegetables, fried food and pickle, welcomed by consumers.

In the cultivation season, it can be cultivated in open field or protected field. Open field cultivation can be carried out in spring and autumn. In spring, it is sown from mid March to early May and autumn from early August to late September. The cultivation time is from early October to early March of the next year.

 Techniques of planting Cherry Radish in plug

Soil preparation and fertilization of Cherry Radish has strong adaptability to soil, but the sandy loam with loose and fertile soil, good drainage and water and fertilizer conservation is the best. Deep ploughing, sun drying, leveling, fine harrow and even mixing of fertilizer and soil are required for soil preparation. Generally, small flat border cultivation is adopted, with a width of 1 m. Due to the short growth period and small fleshy root, the type and quantity of fertilizer are not strictly required. Therefore, it is necessary to apply sufficient base fertilizer instead of topdressing. 4000 kg of fully decomposed manure was applied as base fertilizer and 5-8 kg SSP was used as seed fertilizer.

The sowing method is generally drill sowing, the plant spacing is 3 cm, the row spacing is 10 cm, and the seed amount per mu is 100 g. It can be used for seed soaking, germination and sowing, or direct seeding. Prunus Cerasus Radish planting If the leaves are too dense and the light is not enough, the petioles will become longer, the leaves will be pale, and the lower leaves will be yellowing and shedding, and the fleshy roots will not be easy to expand. The seedlings should be set when the cotyledon unfolds and when there are 3-4 true leaves.

Water and fertilizer regulation should pay special attention to keep the soil moist, watering should be balanced, and the soil moisture content should be 70% - 80% of the field capacity. If the seedling growth is not good and there is a lack of fertilizer symptoms, a small amount of available nitrogen can be flushed with water.

In order to eliminate the competition of weeds for nutrients and promote the absorption of nutrients by roots of radish, it is necessary to cultivate and weed in time to eliminate the competition of weeds for nutrients. Especially in autumn cultivation, it is high temperature and rainy season, weeds grow vigorously, so we should strengthen cultivation and weeding.

The Cherry Radish has strong cold resistance, but not heat resistance. When the environment temperature is over 25 ℃, the growth is not good, and diseases and insect pests are easy to occur, mainly virus diseases and aphids.

The suitable harvest period is about 30 days, and the specific harvest time is different under different cultivation seasons and cultivation methods. When the fleshy root is beautiful and bright and its diameter is up to 2 cm, it can be excavated.

High efficient cultivation techniques of Cherry Radish in greenhouse,

Cherry Radish is very popular with consumers because of its delicate quality and rapid growth. In order to realize the annual supply, the greenhouse cultivation techniques are introduced as follows.

1、 Select varieties. Red skin varieties introduced from Japan were selected, such as 20 day big root, 2-3 cm diameter, 15-20 G single bulb weight, 20-30 days growth period; 40 day big root, 2-4 cm diameter, 20-25 G single bulb weight, 15-22 ℃, 30-40 days growth period, and slightly longer winter time.

2、 Fertilization and soil preparation. plant It is better to choose neutral or slightly acid sandy loam soil for Cherry Radish. Due to the short growth period of Cherry Radish, there is no need for topdressing. Therefore, the base fertilizer should be applied fully. 1500-2000 kg of high-quality decomposed organic fertilizer and 15-20 kg of NPK ternary compound fertilizer with 25% total content should be applied per mu as seed fertilizer to promote root and stem expansion. After fertilization, deep ploughing, fine soil preparation, removal of debris, weeds and other debris, to make a flat border.

3、 Sowing at suitable time. Generally from late September to early March of the next year, sowing can be arranged to connect with open field cultivation in early spring and autumn to form annual cultivation supply. Cherry Radish is suitable for furrow and drilling. Shallow furrow with a depth of 1.5cm is suitable for Cherry Radish planting. Sufficient bottom water is poured. After the water seeps, the seeds are seeded according to the spacing of 3cm, and the soil is about 1.5cm. The growth period of Cherry Radish is short and the plant is short. It can be used for intercropping and interplanting with crops with longer growth period to increase the yield per unit area. For example, in the greenhouse intercropping with lettuce, the Cherry Radish has been harvested before the lettuce will be closed.

4、 Field management. 1. Adjust the temperature and humidity. After sowing, the soil should be kept warm to 22 ℃ ~ 25 ℃ for about 2-3 days; after excavation, it should be cooled down to 18 ℃ ~ 20 ℃; if the temperature is higher than 25 ℃, it must be winded (bolting will occur if the temperature is higher than 25 ℃), and the temperature in severe winter night should be kept above 5 ℃ [source: www.nczfj.com /]. In principle, the field should be kept moist, and the soil water holding capacity should reach 70% - 80%, and the watering should be even. In general, the number of watering is more in the early autumn and late spring, and the surface is not white and dry in deep winter. 2. Generally, no topdressing is needed. If the base fertilizer is insufficient, liquid fertilizer can be applied along with water. 3. When the cotyledons are unfolded, the seedlings should be thinned, the weak and stacked seedlings should be removed, and the seedlings should be set before 3-4 leaves of the true leaves. At the same time, the soil loosening and weeding should be carried out in combination with the intermediate seedlings. 4. Pest control. Due to the short growth period of Cherry Radish, there are generally no diseases and insect pests. It can be sprayed with Agricultural Antibiotic 120, agricultural streptomycin and abamectin in the early stage.

5、 Harvest in time. Cherry Radish should be harvested in time when the diameter of fleshy root is 2-3cm. Generally, it should be harvested about 30 days after sowing and seedling emergence. The fiber will increase after harvesting too late, and the root and bran core are easy to crack, which will affect the commodity quality.

6、 Precautions. In order to obtain high-quality and high-yield Cherry Radish, and to prevent or reduce the products with poor commercial properties such as uneven shape, cracks, forked roots and chaff core, the key is to select neutral sandy loam soil, apply sufficient high-quality decomposed organic fertilizer before sowing, deeply plough and fine soil preparation, and loosen the soil after emergence and middle ploughing to keep the soil moist.

Prevention and control of main diseases and insect pests ① control method of Damping off disease: a small amount of active milk was diluted with water in the proportion of 1:4-5, and sprayed once every 2-3 days. ② Before the onset of black spot, 75% chlorothalonil WP 500-600 times liquid or 50% Suke powder 1500 times were used to control the disease every 5-7 days. In the early stage of the disease, 50% carbendazim WP 800 times solution was sprayed once a week. ③ Aphids and Pieris rapae are easy to occur in high temperature and drought, so they should be watered in time. 2.5% deltamethrin 2000-2500 times solution should be used in the initial stage of insect damage.
