In the planting method of big leaf celery, farm manure is the main fertilizer.

Land preparation and bed preparation: turn the land deeply around 25cm, apply high-quality farm manure to make long beds. Colonization: choose the middle and first ten days of June for colonization, which needs to be watered thoroughly after planting. Fertilization: slow seedling before fertilization, fertilization frequency of about once a month, mainly farm manure, conditions allow to pursue biogas fertilizer. Management: to ensure the temperature to do a good job of watering, weeding, loosening soil and other work.

First, prepare the land and make beds.

First of all, turn the land about 25 centimeters deep, then apply the rotten high-quality farm manure to the soil at a rate of 3000 kilograms per mu, and then make a long bed every 2 meters, with a width of about 1.5 meters, a height of 18 centimeters, and a length of 12 meters. The spacing between the beds is about 35 cm. If it is planted in a solar greenhouse, two micro-spray water supply belts should be assumed at a height of 40 cm above the ground.

II. Colonization

The seedlings can grow to about 8 centimeters in mid-early June, and then the seedlings of celery can be planted. Before planting, the border surface should be raked flat, and the hole spacing and row spacing should be set up. The hole spacing and row spacing are all about 9 cm. About 3-4 plants should be planted in each hole, and the depth of ditching should reach about 15 cm. After planting, try to water thoroughly, so that you can ensure that the seedlings can grow better.

III. Fertilization

After slowing down the seedlings, you can start to apply fertilizer, the time of fertilization is once a month, mainly to apply thin farm manure, about 1000 kilograms each time. If the conditions are promised, biogas manure is more beneficial to the growth of celery. During the period from early August to late September, it will also be sprayed with 0.3% Mel 0.5% potassium dihydrogen phosphate 2-3 times and receive more sunlight, which can promote the development of root system and increase root tiller.

IV. Management

1. When the light is strong, it is necessary to hang a sunshade net to prevent sunburn, and at the same time ensure that the dishes are fresh and crisp.

Then, according to the weather conditions, it should be watered properly, and each watering must be thoroughly watered. At the same time, in the process of management, it is necessary to maintain the wetness of the surface at all times.

3. In the process of growth, weeding and loosening the soil should also be carried out. When loosening the soil, the depth is about 3 cm. Do not go too deep, so as not to hurt the roots.

4. The temperature of celery needs to be controlled during the whole growth process. For example, after the ground leaves withered, it will enter the physiological dormancy period, which needs low temperature to release, so it needs to be treated with pelvic membrane at this time to heat up at an appropriate time. If heating up too early, it will lead to dormancy difficult to release, heating up too late can not guarantee the time to market.

5. In December, the release time should be reduced as much as possible, and special attention should be paid to the heat preservation at night. When the weather is cold, grass grass can be used to adjust the temperature and humidity in the shed.
