TwoPlantation managementRadish budThe northern field can be planted from april to october, and from november to march of the following year it is produced in a plastic shed or in an improved sun. High-temperature periods must be weathered and warm when cold. It's best to use the saber method. Grounds of production will be levelled, bricks will be built to a width of 1 metre, open-ended seedbeds will be laid, thin sand will be laid inside the bed, 10 cm thick, and sand beds will be sprayed and planted with hot water. When sowing, the immersed seed is mixed with dry sand twice the amount of the seed, which is then evenly distributed. In general, about 200 grams of sand are broadcasted in 1 square metre, followed by sand coverings of 1. 5 centimetres thick, and the membrane is kept warm and humid. Soil can also be cultivated, but the soil needs to be lax, fertile and to be applied with a small amount of nitrogen fattening, flattening the surface and watering the bottom water. A square metre is used to sow 120 to 250 grams of seeds, sand or sand, 1. 0 to 1. 5 centimetres thick, with straw curtains or black sunnets. In the morning and evening, water is sprayed, temperature is maintained at 15-20°c, 3-4 days. At this point, cover will be removed in time, water will be sprayed, sand cover will be lifted or soil will be dispersed and the soil will grow. After seeding, visible light grows. If the sun is strong, it should be covered with a black sunnet. 0. 5% nitrogen fatter at heights of 3-5 centimetres. Later, when dry, water is sprayed with thin eyes. It's not appropriate to spill too much water to prevent a sudden fallout. Nor should it be too dry, otherwise the seedlings are ageing and of poor quality. Three days before the harvest, when the bud grows five centimetres long, the cover is removed and greened in a weak light. In this way, the embryos of the seedlings are straight, white and of good quality. You can sow the earth one time, 8 to 10 centimetres thick, or cover it in two, so that the light of the seedlings can be softened, harvested, green and white, and of better quality。
