Softening cultivation technique of celery

Celery is a vegetable with petiole for edible. If the cultivation and management is not fine, the fiber often increases and loses its edible value. The cultivation of celery by softening method can reduce the content of cellulose, decompose the chlorophyll in the petiole and form lutein, so as to improve the edible value, increase production and generate income. The method of softening cultivation is: pile soil softening method pile soil softening requires celery row spacing 33-40 cm. When the seedling is 35-50 cm high, apply heavy fertilizer once and pour enough water three times in a row. After 5-7 days, tie up the base of each clump of plants with straw, loosen the soil again to make the soil slightly dry, then cultivate the soil on both sides of the plant, and pat the soil tightly to make the soil surface smooth. The thickness of the first cultivation is about 4 cm, and then the soil is cultivated again after 2-3 days, so that the soil is cultivated continuously for 5-6 times, with a height of about 20-25 cm, so that the heart leaves of the plant are exposed and do not hurt the buds. The best time to cultivate the soil is in the afternoon when the soil is sunny and the soil is not wet. It will be harvested in about 30 days. The baffle softening method also requires the celery row spacing of 33 cm to 40 cm. When the seedling is about 35 cm high, first lift the plant up so that it stands upright, exposing the soil between the rows. Then two boards or plastic boards with length 1.7 to 3.5 meters, width 13 centimeters 17 centimeters and thickness 2 centimeters 3 centimeters were placed on both sides of the celery plant, and the ends of the boards were fixed with wooden piles. Cultivate soil 13cm to 17cm thick between the two plates, so that the plant will not be injured, and the soil will not fall into the heart of Chinese cabbage, so as to prevent the plant from rotting. Precocious celery only needs to be cultivated for 1 or 2 times and can be harvested after about 30 days. The requirements of row spacing and seedling height of bamboo pole softening method are the same as above. With a slender bamboo pole, clamp the petiole of the plant along the planting line, tie the two ends of the bamboo with grass or nylon rope, and then cultivate the soil step by step according to the soil softening method, which can be harvested in about 30 days. Natural softening method this method belongs to the softening of close planting and semi-shade. Autumn sowing celery is planted according to 7 cm × 7 cm plants and row spacing, 3-4 plants per clump. The border is surrounded by 20-28 cm of soil, surrounded by straw or reeds, thatched grass and so on. Before the closure of the plant, the middle tillage for 2 times and the application of available nitrogen fertilizer for 3 times combined with the application of available nitrogen fertilizer for 3 times to promote the tillering and leaf growth of the plant, cover the top and seal the row as soon as possible, make the petiole grow in the dark environment and achieve the purpose of petiole softening.
