Fertilize the land a week before sowing, plough the land deeply and rake it finely, and make the border flat and open a good ditch when making the border to facilitate drainage and irrigation. Apply rotten organic fertilizer 5000-7000kg per mu, at the same time, match some nitrogen, phosphorus and potassium compound fertilizer 50kg, spread it evenly on the soil, combine with cultivated land, and mix fertilizer and soil evenly.

3. Sowing and raising seedlings

The excellent seeds with strong stress resistance, strong cold resistance and no disease can be sowed by strip sowing, hole sowing and machine sowing, and the suitable sowing method can be selected. The amount of sowing per mu is about 0.5kg. Control the row spacing when sowing, if the climate, soil and other conditions are good, it can be properly close planting, otherwise it should be sparse planting. After the seeds germinated, keep the soil moist and speed up the emergence of seedlings. When growing to 2-3 or 4-5 true leaves, interseedling and supplementary seedlings were carried out respectively, and some weeds, diseased seedlings and weak seedlings were removed.

Generally, there is no need for topdressing after applying sufficient base fertilizer at the seedling stage. If there is no sufficient base fertilizer, 10 kg of ammonium sulfate can be applied per mu, sprinkled on both sides of the seedlings when fertilizing, do not directly apply to the root system, so as not to cause root burn, watering immediately after fertilization, so that the fertilizer can be quickly absorbed. After transplanting, the second fertilizer was also topdressing 15-20 kg of ammonium sulfate, ditching and watering; the third time in the rosette stage, topdressing 30 kg of ammonium sulfate and 15 kg of calcium superphosphate combined with soil cultivation; the fourth time in the heading stage, topdressing 15-20 kg of ammonium sulfate. Watering is also extremely important, depending on the climate and soil. Water should be controlled at the end of the rosette and watered after the third topdressing.
