1, select the fine species Selection of fine varieties is a prerequisite for obtaining high quality and high yield of summer radish. Therefore, in the midsummer and early autumn high temperature season cultivation of radish, it is necessary to use early-maturing varieties with good heat resistance and strong resistance. 2, apply enough base fertilizer Early-maturing radish has a short growing season and requires high nutrient requirements. The base fertilizer should account for 70% of the total fertilization amount, and 4000 kg of farmer's fertilizer and 30-40 kg of compound fertilizer can be applied per mu. The radish should be cultivated in deep ditch and sorghum, and the height is 25 to 30 cm. 3, sowing seedlings When cultivating radish in summer and early autumn, it can be planted in batches from May to August according to market demand in summer and autumn. The sowing method is a bit of sowing and spreading, which can be reasonably selected according to the type of variety. Large fruit varieties should be on-demand, the plant spacing is 20 cm, the row spacing is 35 cm, the seeding point should be shallow, and the seedlings should be covered with fine soil after sowing; the small fruit varieties can be spread, and the plant spacing of 6-12 cm is maintained after the seedlings. After sowing, the straw can be covered with straw to prevent sunburn, anti-storm and erosion, reduce the loss of fertilizer and water, and cover the noodles with a sunshade net, which is good for the whole seedlings, and should be removed in time after the seedlings to avoid the seedlings or the seedlings being weak. Note that seedlings must be seedlings in the morning and late in the seedlings. The seedlings grow rapidly after being unearthed. When the seedlings grow 1 to 2 leaves and 3 to 4 leaves, the seedlings are separated once, and the seedlings grow to 5 to 6 leaves. 4, fertilizer management The radish needs more water, and the amount of water has a great relationship with the yield and quality. Excessive water, radish skin is rough, but also easy to cause cracks and rot; lack of water at the seedling stage, prone to viral diseases. When the fertilizer is insufficient, the root of the radish is small and lignified, and the bitter and spicy taste is strong and easy to heart. Cultivation should be based on the characteristics of the radish in each growing season and the need for water to balance the water supply, do not suddenly dry and wet. After sowing, pour enough water, and most of the seeds should be poured once again after emergence to facilitate the whole seedling. After planting, the seedlings will soon enter the period of leaf growth, and water should be watered in moderation. In the later stage of vegetative growth, water should be properly controlled to prevent the growth of the roots and affect the growth of fleshy roots. When the plants grow 12 to 13 leaves, the fleshy roots enter the rapid growth period. At this time, the supply of fertilizer and water should be sufficient, and the water can be flexibly watered according to weather and soil conditions. After heavy rain, it must be drained in time to prevent excess water and roots, resulting in cracked roots or rotten roots. In the hot and dry season, it is necessary to insist on watering in the evening, and avoid watering at noon to prevent the tender leaves and the fleshy roots from rotting, and stop watering 7 days before harvest. Radish also has special requirements for nutrients. Boron deficiency will make the fleshy roots black and hearty. In the period of succulent root expansion, potassium fertilizer should be added appropriately. After emergence, the seedling fertilizer should be applied as appropriate before the seedlings are planted. When the seedlings grow 2 true leaves, a small amount of fertilizer is applied. After the second seedling, the cultivating and weeding and topdressing are combined once. During the whitening of the radish to the off-the-shoulder, the second top dressing was carried out. It should be noted that top dressing should not be close to fleshy roots to avoid burning roots. The cultivating and weeding can be carried out in combination with irrigation and fertilization. The cultivating should be shallow and shallow first, first and then far, and stop cultivating after sealing. Disclaimer: Some articles on this website are transferred from the Internet.
