Radish Cultivation Techniques

Fertilizing

Previously, after harvesting, we need to deep plough early, fully freeze and dry the area, break up the harrowing, and apply enough fertilizer. According to the soil condition selection of radish varieties, deep soil can be arranged large into the soil deep varieties, plowing depth should be more than 33 cm; shallow soil, you can choose to enter the shallow small and medium-sized varieties, plowing depth of medium-sized species of 25 cm or so, small species of 15 cm or so. The way of making beds varies according to varieties, soil quality, terrain and local climatic conditions, small and medium-sized radish in the rain, well-drained places with flat bed cultivation, large radish root deep leaves, must be used in raised bed cultivation. In the Yangtze River Basin, no matter large or small radish more deep ditch raised beds, in order to facilitate drainage and irrigation. General bed height 20 to 27 cm, bed width l to 2 meters, ditch width 40 cm.

The root system of radish is developed, and it needs sufficient base fertilizer. Before the ground into the farmyard fertilizer 100 quintals, 25 kg of calcium superphosphate, 50 kg of compound fertilizer, plowed into the soil after harrowing for the bed, so that the soil is loose, fine and even, the bed is flat.

Timely inter-seedling

The radish seedlings out of the ground grow rapidly, to timely inter-seedling, the principle is early inter-seedling, sub-inter-seedling, late set seedling. Early seedlings, seedlings small, pulling seedlings will not damage the root of the retained seedlings; late seedlings can be set than early seedlings to reduce the harm caused by a certain stem borer caused by the lack of plants. Production generally between seedlings 2 to 3 times. In the first true leaves unfolded when the first inter-seedling. In 2 to 3 true leaves when the second inter-seedling. Expansion of each hole selected with the original variety of characteristics of a robust seedling, that is, for the seedling, the rest of the extraction, the number of large and medium-sized varieties of 4,000 to 5,000, small varieties of 10,000 plants.

Water and fertilizer management

In fertilizer management should be done: the first to promote the robust growth of leaves and absorbing roots, for the later fleshy root expansion to lay the material foundation. When the nutrient growth to a certain extent, it must be controlled to promote the timely transfer of nutrients to the storage organs. Flesh root rapid expansion period, must ensure that the leaves have a long life and strong vitality, so that it makes more nutrients, to ensure that the expansion of the fleshy root.

Radish in different growth stages, the water requirements are different. Germination period should have sufficient water, the effective water content of the soil straight above 80%, so that the germination is rapid, the emergence of neat. Seedling period to expansion before a period of time, to less watering in order to facilitate squatting seedlings, prompting the root system to the soil layer deep development. The leaf growth period should be watered moderately to ensure the growth of the leaves. Flesh root growth period, to fully and evenly water supply, to ensure that the soil is moist, to prevent sudden dry and wet. If the water supply is insufficient at this time, it will not only affect the expansion of the fleshy roots, but will also increase the fibrous roots, rough texture, resulting in chaff. However, if the soil moisture is too much, drainage should be carried out in time to prevent the occurrence of root rot. Watering time, early spring temperatures are low appropriate in the morning watering, voltaic best evening watering, in order to reduce the ground temperature.

Fertilizer should be applied according to the law of radish in the growth period of nutrient element needs. Adequate base fertilizer and short growth period of radish can be less fertilizer; large species of long growth period of high yield, fertilizer needs, in addition to applying sufficient base fertilizer, but also need to be staged fertilizer. General fertilizer time and number of times is: the first time in the seedlings produced 2 true leaves when the application of dilute farmyard manure, point sowing strip sowing Shi in the rows, spreading the full watering; the second time in the second inter-seedling ploughing after the fertilizer, the concentration of 20%; to the expansion of a concentration of 30% of the manure and animal fertilizer, and the additional application of calcium superphosphate and potassium sulphate each 5 kg per acre. Small and medium-sized radish applied three times after the fertilizer, radish that is rapidly expanding, can not be further fertilizer. Large fall and winter radish also need to be in the "shoulder" when each mu of sulfuric acid hinge 7.5 to 20 kg, for the needs of the root growth. Chasing the application of farmyard manure and fertilizer, do not be too concentrated and leaning too close to the roots, so as not to burn the roots.

Mid-tillage weeding

After radish sowing seedlings, such as rain or watering caused by soil sloughing, should be timely mid-tillage weeding. The long shape of the exposed varieties, in the early stages of growth must be cultivated to embrace the roots, so that it grows upright. After sealing the rows, generally no longer plowing.
