Scientific planting technology of radish how to grow radish

Although radish is not very likely to be fried as a vegetable, and the taste of fried radish is very ordinary, in addition to stir-frying, radish can also be eaten in stew, cold salad or pickled vegetables. In this way, the sales volume of radish is not a small number.

Scientific planting technology of radish

1. Soil preparation and fertilization: radish is not suitable for continuous cropping with cruciferous vegetables, deep ploughing and ploughing, and applying sufficient basic fertilizer, 3.7 ~ 45000 kg of mature organic fertilizer, 1200 kg of plant ash, 375kg of superphosphate and 750kg of diammonium phosphate per hectare.

2. Sowing at the right time: the sowing time of radish depends on the characteristics of the variety and the needs of the market. The suitable sowing time for autumn and winter radish is from late July to early August, and spring radish can be sowed from late February to early April. The sowing rate varies according to the cultivation density, generally 3kg / ha.

3, and time seedlings: radish planting is usually carried out for the first time when the first true leaf is unfolded, and a strong seedling with the characteristics of this variety is selected when the belly is broken, and other weak plants can be dropped.

4. Reasonable watering: the soil water content of radish is more than 90% in germination stage, 60% in seedling stage, more water demand in leaf growth period, and soil moisture in root growth period is 70-80%. Proper watering should still be applied in the later stage of root growth to prevent hollowness.

Varieties of radish

1. Autumn and winter radish types: common cultivation types in China. Sowing in late summer and early autumn, harvest in late autumn and early winter, the growing period is 60-100 days. According to skin color and use, it can be divided into different variety groups, such as red skin, green skin, white skin and red heart. Representative varieties are Xuecheng Changhong, Jinan green round crisp, Shijiazhuang white radish, Beijing Xinmei and Chenghai Baisha locomotive and so on.

2. Types of winter and spring radish: planted in areas not too cold in winter, such as south of the Yangtze River and Sichuan Province in China. Cold-resistant, strong in winter, not easy to bran heart. The representative varieties are Chengdu spring immature radish, Hangzhou Hanqiao big red tassel radish and Cheng Hainan Luzhou evening radish and so on.

3. Types of radish in spring and summer: widely cultivated in China. It has the advantages of cold tolerance, strong winterness, short growth period, generally 45-60 days, and early bolting easily due to improper sowing time or cultivation management. Representative varieties are Beijing firecracker tube, Penglai spring radish, Nanjing May Red.

4. The type of radish in summer and autumn: it is cultivated more in the south of the Yellow River Basin in China, and it is often used as a vegetable in the off-season in summer and autumn. It is more resistant to moisture and heat, and the growth period is 50-70 days. The representative varieties are Hangzhou small hook white, Guangzhou candle barge and so on.

5. Four seasons radish: small leaves, thin petiole, hairy, fleshy root is small and very precocious, suitable for raw food and pickling. It is mainly distributed in Europe, especially in western Europe, and has been introduced in the United States, and a small amount has also been planted in China and Japan. The four seasons radish varieties cultivated in China are Nanjing radish, Shanghai radish, Yantai Hongding and so on.

Harvesting technology of radish

I. harvesting standards

The main results are as follows: 1. the leaf color turns pale and the underground stem is harvested in time after the underground stem is fully expanded.

2. Require uniform size, no root, no mud, no hairpin, no deformity, no bran heart, no wound, no discouragement.

3. According to the different requirements for the size of radish in the consumer market of different regions, the harvest standards are also different. Some areas want radish of more than two jin, and some areas want radish of less than two jin, so the size standard of harvest should be determined according to the needs of the market.

Second, pre-cooling transport: pre-cooling into the cold storage (2mur4 ℃) for about 10 hours, loading and thermal insulation transportation on the market.

Storage method of radish

1. Pit storage method: cut off the top of the fresh radish, remove the hairy root, and strictly remove the radish with insect injury, mechanical injury, crack and too small. Dig a 1 meter square pit, put the radish root up, top down, lean against the pit wall, code tight in order. Code a layer of radish, sprinkle a layer of pure land about 10 centimeters thick, so alternately put, a total of four layers. If the pit soil is too dry, it can be moistened by spraying water properly. After the last layer is ready, it is necessary to gradually thicken the soil layer according to climate change, cover less soil when the weather is warm, and cover more soil during a strong cold snap. Lesser Cold finished covering the soil before and after, with a total thickness of 1 meter. The radish of good quality is not heated before entering the pit or frozen after entering the pit, and can be stored until early March of the following year.

2. Mud storage method: cut the top of the radish, roll it in the yellow mud, make the radish form a mud shell, and pile it in a cool place. If you cultivate a layer of wet soil outside the radish pile, the effect will be better. Storage method outside the water tank: put a water tank indoors, which is filled with water, pile the radish around the tank, and cultivate 15 cm thick wet soil on top.

In the face of good market sales, planting radish is also a project to get rich. Although the market price of radish is not high, once it reaches a certain scale, and the output and quality of radish are reliable, the benefits that radish can bring are also considerable.
