High quality white radish cultivation technology

Choose suitable soil

For the cultivation of radish, crops with low consumption of fertilizers, many organic substances left behind and no diseases and insect pests of the same kind should be selected as front rakes. The cruciferous vegetables need to be avoided as a forehead, otherwise it is easy to cause diseases. Radishes have a wide adaptability to sandy soil. In order to obtain high-yield and high-quality products, it is still better to use deep, loose, well-drained and relatively fertile sandy loam soils. When cultivated in a suitable soil, the growth of fleshy roots can be fully expanded. The shape is correct, the skin is clean, and the color is beautiful.

Plots require deep plowing

Leveling, uniform fertilization, so as to promote the increase of effective nutrients and beneficial microorganisms in the soil, and can loose air permeability, is conducive to the absorption of nutrients and moisture absorption of roots, so that the leaf area expands rapidly, the meat roots accelerate the expansion. 75 kg of compound fertilizer can be applied as base fertilizer per acre. Then carry out soil disinfection and control of underground pests. The bactericide is selected from 50% carbendazim 600 times solution or 70% thiophanate-methyl 800-1000 times solution spray, and the insecticide can be sprayed with 48% roxithmidine 800-1000 times solution.

sowing

The quality of radish seeds has a great influence on the growth and yield of radish plants. In order to make the seedlings neat, seedling-full and seedling-strong, seeds should be carefully selected, and only full, sound seeds should be used to eliminate pods, crushed, and mildewed seeds. The seeding rate depends on the seed quality, soil quality, climate, and seeding method. Autumn and winter radishes use on-demand or drill. The amount of seed should be determined according to the density of the seedlings, and the on-demand seedlings should be 25-30 cm in diameter, with 4 to 5 seeds per seed, and the seeds should be scattered in the nest so as to avoid crowding after emergence and affecting the seedling quality.

Field management should keep up with

The seedlings grow rapidly after unearthing, and they need time seedlings to prevent crowding, shade and cause leggy. To set the seedlings early, split between the seedlings, timely seedlings to ensure Miao Qi and Miao Zhuang. Intermittent seedlings are usually 2 to 3 times in size, with the exception of the seedlings whose weak, deformed, and pest-infested species are removed.

Reasonably watering

The watering is mainly determined according to the characteristics of the growth of the radish, the requirements of the moisture in each growth period, the climate conditions, and the soil conditions. After sowing, if the weather is dry, immediately pour water once, and then pour water once when the seedlings begin to emerge, keep the ground moist, ensure that the seedlings are neat, and reduce the occurrence of viral diseases. If it is rainy, it must be drained in time to prevent death.

Scientific fertilizer

Winter radish is a large and medium-sized radish variety with a long growth period. Based on the application of basal fertilizer before sowing, suitable topdressing should be applied. Especially for plots with low soil fertility and insufficient basal fertilizer, topdressing can significantly increase yield. Nitrogen fertilization should be used to water or fertilize water. After the radish “breaks belly”, it enters the rose growing stage, that is, the rosette period. In order to promote the expansion of the leaf area, it is also appropriate to apply a quick-release nitrogen fertilizer; when it enters into the prosperous period of the root enlargement of the fleshy root, the top-dressing compound fertilizer will help the root enlargement of the flesh. During the first 20 days before harvest, once a week, spraying 0.2% potassium dihydrogen phosphate two times for foliar dressing has a good effect on improving yield and quality of fleshy roots.

Scientifically cultivating weed pests

During the growing period of radish, many cultivating loose soils are needed. Especially in the seedling stage, the temperature is relatively higher, the rain is more, the weeds grow rapidly, and weeding and weeding are needed. In high ridge cultivation, the soil on the ridge is easily washed by rain, and the cultivator needs to be combined with soil. Long-shaped naked radish, because the root neck is slender and weak, often easy to bend, lodging, the initial stage of growth needs to be bred to expand the root, to prevent the formation of curved radish after lodging. At the end of the rosette, the leaves were already ridged and the cultivator was stopped. Weeding was done only by hand.

The pests of radish are mainly maggots and soft rot, with 12% of agricultural streptomycin sulfate WP wettable powder 10 million units of water plus 50-75 kg or 57.6% of chlorothalonil dry granules 1000-1200 times spray, while Combined irrigation roots. For controlling aphids, Imidacloprids can be used to spray water.

Timely harvest

The harvest of winter radish depends on the variety and time of arrival. The harvest has a low yield and the plate has no taste; the harvested meat root is frozen or hollow, and the quality deteriorates, causing a hollow. When the diameter of the root expands to 8~10 cm and the length is 25~30 cm, the harvesting is more appropriate.

Reviews

Really mastered the points

Zhang Yongji, vegetable technician of the Agricultural Bureau of Jiangyang District, said that Zhang Yiming’s white radish can get a good harvest. It is indeed because he has mastered the basic points of radish cultivation: that is, the seedling temperature is maintained above 10 degrees; the fertile soil is selected and deep plowing is selected. The soil permeability of the soil is good; the row spacing is suitable. The radish seed specifications for each nest sown had achieved a bit of heat preservation and moisturization at the time of emergence. In particular, the timely emergence of seedlings after the emergence of seedlings; and the retention of 5000 seedlings per mu is also a key to the harvest.

If peasants and farmers want to sell radish during the Spring Festival, the sowing date of radish is appropriate in the middle or late September. If it is to be listed after the Spring Festival, the sowing date should be appropriate in the middle or late October.
