Prevention of hollow cultivation of celery

To make celery not hollow, in addition to selecting high-purity, high-quality solid celery varieties, the first thing is to pay attention to the cultivation method.

According to measurements, under the same condition of fertilizer and water, celery cultivated in places with strong salinity, heavy stickiness, sandiness and serious pests and diseases is prone to hollow heart disease. Therefore, celery should be grown on plots rich in organic matter, strong in water retention and fertility, and good drainage and irrigation conditions. Cultivation of celery indoors, the daytime temperature is between 18°C ​​and 23°C, not exceeding 25°C, and at night, between 13°C and 18°C, not lower than 10°C, and the ground temperature is preferably between 13°C and 18°C. The base fertilizer must be adequately applied. The top topdressing in the growth period is mainly based on quick-acting nitrogen fertilizer. The topdressing should be watered in time and can not be defertilized. The measures of frequent watering with small water and frequent application of thin fertilizers should be adopted. Effective ingredient utilization rate of fertilizer. During the vigorous growth period, water and fertilizer should be supplied without interruption, and topdressing should be performed every 15 to 20 days.

In addition, spraying Zhuangqianling at the right time during the growth period of celery can make the plant stalks thick, thick leaves, fresh and tender leaves, lush plants, and strong natural taste. At the same time, it can improve the anti-disaster ability, reduce the amount of pesticides and fertilizers, and reduce the residual toxicity. At the same time, it should be harvested in time. If the harvesting period is too late, the petiole is aging, the ability of leaves to produce nutrients is reduced, and the absorption capacity of the root system is weakened. Insufficiency causes the parenchyma cells in the petiole to rupture and form a hollow phenomenon.
