What are the management techniques in the process of autumn radish planting?

First of all, we must pay attention to the soil moisture of carrots, secondly, we should also spray some antibacterial drugs when planting carrots, and secondly, we should also water more and fertilize more, so as to improve the yield of carrots, and also make carrots grow bigger and stronger, and the taste will be better.

Pay attention to the weather, pay attention to the temperature, be sure to choose high-quality root seedlings when planting radish, and then plant them in fertile soil, plant them at a distance, water more and fertilize more, pay attention to the insect disaster of radish at any time, and spray pesticides on time.

It is very important to pay attention to the condition of the soil, to maintain adequate nutrition, to pay attention to the temperature, and to pay attention to the prevention and control of pests and diseases.

During the planting of radish, we should maintain sufficient nutrition, apply more farm fertilizer, organic fertilizer, nitrogen, phosphorus and potassium fertilizer, you can also increase urea, ammonium sulfate, etc., and also need an appropriate amount of watering, maintain the principle of less watering and frequent watering, now during the growth of the fruit, you must not water too much, and also pay attention to the prevention and control of pests and diseases, pay attention to weeding, pay attention to soil disinfection, you can make autumn radish grow better.

Radish autumn and winter cultivation should choose a plot of convenient drainage and irrigation, it is best to sandy loam soil and loam soil, before sowing must be timely ploughing, ploughing time should be early, the quality of cultivated land should be good, the depth of cultivated land should be consistent, based on base fertilizer, supplemented by top dressing, combined with the situation of the whole acre, and with the appropriate amount of chemical fertilizer.

Planting radish with deep soil layer, good water retention and drainage, loose and breathable sandy soil is better, and the growth period of radish in autumn and winter is 80-100 days. The northern regions have a shorter season for growing turnips. The later stage cools down quickly and freezes early, so the requirements for the sowing period are stricter.

In the colder areas of the northeast and northwest, sowing in early and mid-July, harvesting in early and mid-October, radish crops should be prepared in time after harvesting, requiring deep ploughing, leveling and loosening, so as to ensure that the seedlings are all strong and strong. Combined with land preparation, sufficient base fertilizer should be applied, field management should be done, watering after top dressing, and vegetable borer and aphids should be controlled in time. The turnip fly in Northeast China is seriously damaged in autumn, the soil is short of water, and the growth of fleshy roots is hindered, which is rough and spicy, and reduces the yield and quality.

Watering is generally stopped 5-7 days before harvest.

After the radish crop is harvested, the land should be prepared in time, and it is required to be deep, flat and loose, so as to ensure that the seedlings are all strong and strong. Combined with land preparation, sufficient base fertilizer should be applied, and the amount of base fertilizer should account for about 70% of the total fertilizer, that is, 4000-5000kg of well-decomposed high-quality manure, 50kg of herbaceous ash, and 25-30kg of superphosphate should be applied per mu.

Management of the peak growth period of fleshy rootsThis period is the main period for the formation of radish product organs, which requires more fertilizer and water, and needs to be watered in time after the second top dressing, and then watered once every 3-5 days, and often keep the soil moist. If the soil lacks water, the growth of fleshy roots is hindered, which is rough and spicy, reducing yield and quality. Watering is generally stopped 5-7 days before harvest.

There are many kinds of radishes in our country, and they are widely planted. Autumn and winter radish, planted in late summer and early autumn, harvested in late autumn and early winter, the growth time is shorter, in the area above ten degrees Celsius can be planted, select high-quality radish seeds before planting, germination and disinfection treatment, in the loose soil, good ventilation and light transmission of the land preparation, apply enough base fertilizer, do deep ploughing, leveling, loose, so as to ensure that the seedlings are strong, radish seedlings grow, and time seedlings, to avoid crowding and growth, after planting need to be timely top dressing, for low soil fertility, insufficient base fertilizer land, Top dressing can significantly increase the yield of radish, and fertilization should be mainly based on nitrogen fertilizer.

1. Seedling management.

Whether it is strip sowing or hole sowing, after the radish seedlings emerge, the seedlings must be thinned. Seedlings are thinned after two true leaves have grown to prevent the seedlings from growing crowded, and the seedlings are thinned for the second time when there are three or four leaves, and then the seedlings are set. This is a very critical management of the seedling stage, and the purpose of multiple seedlings is to promote the growth of seedlings and remove weak seedlings, disease and insect seedlings.

2. Watering and top dressing.

Improper watering and fertilization of radish will affect the yield and quality, such as in the fleshy root growth period, drought for several days, do not water, wait until the upper leaves wilt, and water once. This watering method is incorrect, it is easy to leak the bran heart, and the spicy taste is heavy, which affects the quality and taste.

Frequent watering of radish seedlings can reduce ground temperature. During the rosette stage, the above-ground leaves grow vigorously, and the fleshy roots have just begun to grow, so you can properly control the water and squat the seedlings during this period, and water them when the ground is slightly dry. When it comes to the growth and expansion period of fleshy roots, the water demand increases, and the watering should be even, not dry and wet.

3. Pest control.

The general diseases in the radish growth period are less, but the impact of pests is relatively large, such as vegetable borer, jumping beetle, cabbage worm, etc., which will also spread pathogens. For example, emamectin benzoate, indoxacarb, cyhalothrin and other silver traps should be prevented and controlled as soon as possible at the seedling stage.

In the autumn planting process, the management of the above three aspects is very critical, the fleshy root of the radish is hypertrophied, and it is not hollow, and the taste is good, so that the best of the radish can be improved.

To set the seedlings, and then to weed, it is necessary to actively water to ensure the moisture of the soil, and also to properly ventilate to avoid too dense planting.

It is necessary to carry out seedling setting in time, but also pay attention to the time of sowing, and carry out deep ploughing in time. It is necessary to carry out land preparation in advance, and the management of water and fertilizer should be strengthened.
