The nutritional value and flavor of broccoli are higher than that of white cauliflower, and the contents of protein, amino acid and vitamin E are higher than that of white cauliflower. The cultivation is easy and the supply period is long, and it has a promising future. The number of days from sowing to harvest varies with maturity, with early maturation of 90 to 100 days, medium maturation of 100 to 110 days, and late maturation of 120 days. The broccoli must be planted in two weeks to dry, wet, and promote hairy roots; after two weeks, it should be kept moist in the field; the water should be used to regulate the fat; after budding, sufficient water must be ensured; if necessary, furrow irrigation can be performed; the ditch system can be cleaned to ensure that it is rainy. There is no water in the ditch. The export of broccoli requires that the plants be firm and robust, the curd is tight and round, and not hollow, so the fertilizer can not be too much. Apply more organic fertilizer as base fertilizer, topdressing fertilizer with nitrogen, phosphorus and potassium, use compound fertilizer, apply urea in proper amount, and do not use it later. One-sided application of nitrogen fertilizer to prevent hollow. Miao Fei: After planting and returning seedlings, apply 0.5% ammonium bicarbonate and 1% superphosphate, apply fertilizer once every 5 days or so, and use the principle of wet deposition. Fat tree fat: 10 leaves or so, with 1% urea pouring tree fat, vegetables and more facilities, vegetables and small facilities, sunny light, heavy rain, and often watering, keep the soil moist. Flower ball fertilizer: When the flower ball fertilizer is reused, when the flower ball is presented, 30 kg of compound fertilizer is applied per acre and 15 kg of urea is applied during the expansion of the flower ball to promote bulb expansion. Watering of broccoli before harvest will increase the decay of the curd during storage. Therefore, before harvesting, watering should be reduced, flooding should not be allowed, and irrigation should be stopped 7-10 days before harvesting. In the cultivation process, more phosphorus and potassium fertilizers and trace fertilizers should be applied. In the absence of potassium, the "black heart" phenomenon occurs in the center of the flower bulb. Boron deficiency can cause cracks in the interior of the flower bulbs and brown spots in the flower bulbs. Broccoli must be covered or bundled with leaves to protect the flower bulbs during and after the growth of the flower bulb.
