Stem mustard (cucumber) is a good crop for winter agricultural production, but it is found in production that farmers do not pay attention to late-stage topdressing once they are transplanted, resulting in low yields. Basal fertilizer is generally applied per acre rot 2000 to 3000 kg of organic fertilizer or 45% of compound fertilizer 60 kg. After spreading, the cultivator will plow into the soil, and then transplant and transplant. The top-fermented mustard should be top-dressed according to different cultivation conditions and stem and leaf growth characteristics. The main nitrogen fertilizer, nitrogen fertilizer generally 25 ~ 30 kg per acre. Three applications. For the first time after transplanting, the plants entered the 8-leaf stage (before December 15th) when the temperature was higher. The leaf grows fast, and only the top dressing can be formed in time to form the first leaf ring, which lays the foundation for the enlargement of the stem. Generally, 1,500 to 1,750 kilograms of manure is collected per mu, or 4 to 5 kilograms of urea, and 1,000 kilograms of water is added. The second topdressing was carried out in the 13 leaf stage (middle of January to early February). At this time, the growth rate of stems and leaves was very fast. Generally, 25 kg of ammonium bicarbonate per mu, 20 kg of superphosphate, and 5 kg of potassium chloride were used per mu. , add water 1500 kg pouring. The third time dressing is carried out in the 15 leaf stage (late February). 25 kg of urea plus 12.5 kg of potassium chloride per acre is added for water application. Do not apply or apply nitrogen fertilizer. Every 7 days, depending on the growth situation, follow up. 1 fat. One month before picking, stop top dressing to prevent growth from being too fast and hollow.
