High yield softening cultivation technique of celery in the late season
The celery softening cultivation is softening of the soil, after softening the celery, the petioles are tender, the scent is lightened, the texture is crisp, the taste of the food is good, and the quality is good. The key to softening cultivation of celery is to make the soiling time suitable. The premature soil is perishable due to high temperature. Generally, the monthly average temperature drops to about 10 °C, and when the height of the plant is about 25 cm, the soil is started. Since the soil is no longer watered after the soil is cultivated, the large water is continuously poured three times before the soil is cultivated, so as to meet the water requirement of the plant growth after the soil is cultivated. Choose a sunny day when there is no water on the leaf surface. Use soil to be finely crushed, no clods impurities, and can not be mixed with manure, so as not to cause decay, once every 2 to 3 days, usually 4 to 5 times, the thickness of each soil should not cover the heart, and finally The total thickness of the soil is 17-20 cm, and the total thickness of the groove width is about 30 cm. After softening cultivation of celery, the petioles are white and tender, and the quality is improved. At the same time, the soil has a cold-proof effect, and the harvesting period can be appropriately delayed to increase the yield.
