Cabbage according to growth phase fertilizer effect is good
Chinese cabbage has a high yield and requires a large amount of fertilizer. Do not worry about top-dressing on the basis of applying basic fertilizer. Top dressing depends on different growth periods and seedlings. Seedlings are generally not top-dressing. If the base fertilizer is insufficient, for the first time in 3 to 4 true leaf stages, 10 kg of ammonium sulfate per acre will be applied to both sides of the seedlings and immediately watered, called “raising seedlingsâ€; After transplanting seedlings, apply 15-20 kg of ammonium sulfate per acre to apply ditching on both sides of the ridge, and call it “fertilizerâ€. For the third time, in the rosette stage, 25-30 kg of ammonium sulfate per acre is used. Calcium 10 ~ 15 kg, the fertilizer applied into the ditch or hole, and then a little earth ridge ridge, and then watering, called "big top dressing"; the fourth time in the middle of the ball, ammonium sulfate 15 ~ 20 kg per mu, Can be flushed with water, said "heart filling fat."
During the period from Chinese cabbage to rosette, the temperature of the cabbage is gradually reduced and the weather is mild. Here, it can be properly watered. The lotus can be properly controlled for a few days at the end of the rosette and watered after the third topdressing. After entering the ball stage, Chinese cabbage needs the most water. Therefore, once the seedlings are finished, they must be poured with water once, and then the second water is poured every 2 to 3 days. This time it is very important. When the soil is dry, it will be dry. The lateral roots are broken and the fine roots are dead and affect the nodule. Afterwards, water is usually poured 5 to 6 days to keep the soil moist.
