Can pregnant women eat radish? How do you plant it? What are the high-yield cultivation techniques?

Radish is one of the ancient cultivated crops in the world, also known as radish, flowering from April to May and fruiting from May to June. Seeds, fresh roots, withered roots and leaves are all used as medicine. Can pregnant women eat radish? How do you plant it? What are the high-yield cultivation techniques?

Can pregnant women eat radish?

Sure. Pregnant women can eat white radish, but pay attention to the cold nature of white radish, to the right amount, not too much. Radish is a cold vegetable, Yin Sheng partial cold constitution, spleen and stomach deficiency cold should not eat more. Patients with gastric and duodenal ulcers, chronic gastritis, simple goiter, threatened abortion and uterine prolapse should eat less radish.

How do you grow radish?

The main results are as follows: 1. Variety selection: the fast-growing radish varieties should use new seeds produced in the same year with full grains, no damage, strong germination potential and high germination rate.

2. Site selection: radish production does not require high temperature and humidity conditions, generally does not need too much light, but requires fresh and smooth air. Put it on the balcony or on the balcony.

3, container selection: foam boxes of various specifications are available, generally choose boxes with a length of 60 cm, a width of 40 cm and a height of 25 cm. The bottom of the box is required to be flat with drainage ventilation holes.

4. Sowing operation: first wash the seeds and remove the blighted seeds and impurities floating on the water surface. Then soak in 20 ℃ warm water for 12-17 hours, and rinse and change the water once in the middle. Put a layer of newspaper at the bottom of the foam box, spread 2 cm thick clean river sand, spread the soaked seeds evenly on the sand surface of the box, and then cover the foam box with a layer of black plastic film to keep warm, moisturize and block the light. The temperature in the box should be kept at 23-28 ℃ and water should be sprayed 2-3 times a day.

5. Cultivation and management: the suitable temperature for the growth of radish is 18-25 ℃, spraying more water to cool down in summer and strengthening heat preservation in winter. During the growth period, the water should be drenched 3-4 times a day, and the clean well water should be used. Each time, the sprouts were all wet and the matrix was soaked. During the cultivation period, the room should be kept dark and invisible, otherwise the peanut buds will turn green and affect the appearance and taste.

6. Prepare for harvest: in the normal cultivation environment, from sowing to harvest, it takes 7-8 days in summer and autumn, and 8-10 days in winter and spring, when the bud grows 12-15 cm, the top valve is expanded without cotyledons, no rotten stem, no smell, no root, it can be harvested.

What are the high-yield cultivation techniques of radish?

Radish is a kind of vegetable with fat fleshy taproot as its product. it is rich in a variety of trace elements and rich in nutrition. it has the effects of anti-cancer, heat-clearing and detoxification, antibacterial and detumescence. More varieties, according to the color can also be divided into carrots, white radish and green-headed radish. According to the cultivation season, it can be divided into spring radish, summer radish, autumn radish, winter radish and four seasons radish. Spring radish in Yunnan is generally planted from November to January of each year, and the harvest is from February to May; summer radish is planted from March to April and harvest is from May to August; autumn radish is planted from June to July and harvest is from August to October; winter radish is planted from August to October and harvested from the end of November to February of the following year.

First, prepare before planting

1. Site selection: it is best to choose the plot where melons, legumes or eggplant vegetables are planted in the previous crop. Because radish is a deep-rooted crop, it is required to plant deep soil, loose and fertile soil, preferably loam or sandy loam.

2. Soil preparation: at present, the withered branches, leaves and weeds in the field should be removed in time after harvest, and then the soil should be ploughed deeply for 25 minutes and 35 minutes. It is more ideal to dry the ground for 6 days. Before planting, each mu of rotten farm manure, 30kg of calcium, 30kg of potassium sulfate and 0.5kg of borax are applied. During soil preparation, the fertilizer is poured into the soil, and the soil moisture can be adjusted after fine ploughing and raking.

3. Manage soil moisture: it is recommended to plant high soil moisture in summer and autumn, with a width of 1m and a height of 20cm. Soil moisture can be made flat or low in winter and spring, with a width of 3m.

4. Sowing: radish planting is carried out by digging pond and sowing on demand. Generally, ordinary seeds are sown with 6 seeds per pond, with a seed amount of about 500 grams per mu, while coated seeds are sown with 2 seeds per pond and about 150 grams per mu. Cover about 1 cm of fine soil or dung after sowing. Planting density is determined according to variety characteristics, soil fertility and cultivation season. For the varieties with large leaf development and high yield, it is recommended that the row spacing should be 35ml / 40cm. The leaves are few, the leaf type is erect, and the recommended row spacing of radish with smaller individual is 25ml / 30cm.

II. Field management

1. Seedling setting: intermediate seedlings and fixed seedlings should grasp the principle of early and late setting. Generally, seedlings should be fixed twice. For the first time, when the first true leaf is unfolded, the thin and weak seedlings and the seedlings of diseases and insect pests should be pulled out, and 4 seedlings should be left in each pond. When there are 4 leaves in 3Mel, there are two seedlings in each pond. The seedlings were fixed at 5 Mel 6 leaves, and it was suggested that one strong seedling should be left in each pond. For coated seeds, one-time fixed seedlings will be carried out when the leaves are 5 leaves, and a strong seedling will be left in each pond.

2.Intermediate ploughing and weeding: the radish should be ploughed and weeded twice during the growing period. Master the principle of deep before shallow, near before far, and stop ploughing the radish after closing the row. The purpose of intertillage is to loosen the soil, remove weeds, increase soil temperature and promote growth.

3. Irrigation: there is a higher demand for water during the growth period of radish. After sowing, irrigation should be carried out according to soil moisture to promote seed germination. The root distribution of radish at seedling stage is shallow and the absorption capacity is weak, so it should be irrigated gently and frequently to keep the soil moist. In the period of vigorous growth of stems and leaves, in order to prevent overgrowth, moisture should be properly controlled. Fleshy root expansion period, large water demand, should be adequate water supply, otherwise radish root thin, low yield, but also due to lack of water to cause bran heart, fiber and spicy taste. In the rainy season and low-lying areas, pay attention to drainage to prevent rotten roots and black hearts, and stop irrigation within 1 week before harvest.

4. Topdressing: the principles of combination of organic fertilizer and inorganic fertilizer, nitrogen, phosphorus and potassium, base fertilizer and topdressing should be mastered in radish planting and application, and single application of nitrogen fertilizer should be avoided. The ratio of nitrogen, phosphorus and potassium is about 1: 0.5. The application of boron fertilizer in radish can reduce the occurrence of black heart disease, and 0.1% boric acid can be used as extra-root topdressing if necessary.

III. Harvest

When the fleshy root of radish is fully dilated, the leaf color turns pale, and begins to turn yellow, when the root head appears coarse grain, it should be harvested in time, otherwise it is easy to cause fibrosis or bran heart. The specific situation is determined according to the difference of season and variety. Under general conditions, summer and autumn radish can be harvested in 70 days after planting, while late-ripening winter and spring radish can be harvested in more than 100 days.
