How to manage celery in winter if you want to produce high yield? (with key technology)
Celery is a vegetable that people like very much. It has high nutritional value and good medicinal value. It can be eaten by cooking or juiced. It is a vegetable with a market. Many people will grow vegetables, so what kind of management measures should be done to grow celery in winter? Let's take a look!
Celery winter planting high yield management
Celery prefers a cold and humid growing environment, and it is more common in the north of China to grow spring and autumn celery. In the winter, in addition to the winter land that is used to grow winter wheat, it is almost idle for a whole winter. If the autumn sap crops are harvested, the winter celery is planted, not only the unused land is used, but also the high-quality celery with fine meat and crispness and fine fiber can be planted without affecting the cultivation of spring sorghum crops. Moreover, growing vegetables in the off-season, the market supply is small and the sales volume is large, and it can be sold on New Year's Day, Spring Festival, and after the year. The price is also good, and the return is still very rich.
Breeding seedling
Celery cultivation is relatively simple, and management is relatively less troublesome. Only frosty areas need only ordinary plastic greenhouses. In winter greenhouse cultivation, it is recommended to use varieties with low temperature resistance, strong disease resistance and high growth potential.
In the greenhouse, winter celery, usually begin to grow in mid-August. The celery seeds are small, in order to ensure the emergence rate, we should deal with the seeds before planting. Dry the selected seeds for 2-3 days, then soak them in clean water for 1 day (24 hours), then smash the seed shells of most of the seeds, and then wrap them in a damp cloth and place them in the environment of 15-20 degrees Celsius. Usually 4-5 days, most of the seeds are white, so you can plant them. During germination, pay attention to the seeds and do not let it mold.
The celery seeds are small, the seedlings are thin and thin, and the seeds are germinated and emerged after over-drying, and the seedling management is not good. Therefore, the nursery bed should be selected in a place where the soil is fertile, the terrain is high, and the irrigation and drainage is convenient. Before planting, fertilize and turn the ground to make the cockroaches. The width of the raft is about 1.5 meters, the length is about 20 meters, the soil is fine and flat, and then the seeds are evenly spread in the raft, and then the soil is covered.
It should be noted that when small seeds are spread, it is not advisable to grasp them. The seeds and fine soils can be mixed evenly before being spread; when sowing, the soil moisture in the sputum should be ensured. If the drought can be sown after irrigating. After the sowing, a sunshade net can be set up on the surface to prevent the sun from squeezing and causing the soil to smear, and to prevent the rain from scouring the surface.
Colonization and management
Before the emergence of seedlings, the soil should be kept moist to ensure the emergence of seedlings, seedlings and seedlings as soon as possible. After the seedlings, when the seedlings are 2-3 leaves, it is necessary to make a seedling between the seedlings, keep the distance between the seedlings about 2 cm, and remove the weeds at the same time. During this period, the amount of water should be controlled as much as possible. Keep it moist and avoid water accumulation.
About one month after sowing, nitrogen fertilizer can be applied once according to the growth condition to promote seedling growth. At the seedling stage, it is necessary to pay attention to observation, actively control pests and diseases, mainly to prevent mites and trips, and avoid loss should be treated as soon as possible.
When the seedlings grow 5-6 leaves, they can colonize the field. The field is applied to the base fertilizer, about 3,000 kilograms of high-quality organic fertilizer is applied, and about 30 kilograms of phosphate fertilizer is used. The deep tillage is fine and flat, ready for transplanting and planting.
When seedlings are planted, the seedlings should be screened for survival of the fittest, and the sick and sick seedlings, weak seedlings should be eliminated, and the strong seedlings should be planted. The depth of planting is suitable for the soil and soil. The roots are not exposed, and the plant spacing is about 30 cm. The density should be appropriate. After planting, watering should be done in time to speed up the growth of seedlings. In addition, the air temperature is higher after planting, and the soil moisture evaporates quickly. Generally, water is poured once every 4-5 days to ensure the growth of new roots. After watering, it is generally necessary to cultivate once to keep the soil loose and transparent.
Field management
In order to maximize the benefits, the celery in our greenhouse will be harvested and listed near the Spring Festival. Therefore, we must have a scientific and strict management of celery.
1, temperature. After planting, the temperature in the previous period should be kept at 15-25 degrees Celsius during the day, not less than 10 degrees Celsius at night, and the ground temperature is maintained at around 20 degrees Celsius. In the early stage, when the temperature is high at noon, the window can be properly ventilated and damp. After the frost falls, when the temperature drops to 12 degrees Celsius, the window is ventilated. After the frost, it is also necessary to cover the grass and other things that are cold and warm. After covering the heating objects, pay attention to uncover the light in time and cover the insulation in the evening.
2, topdressing. Probably in November, when celery grows a lot of new roots and leaves, it needs a large amount of fertilizer at this time. It can apply about 20 kg of compound fertilizer per mu, and then follow up the growth of the plant and apply nitrogen fertilizer once. The growth of celery requires trace elements. Boron can prevent the celery stem from being rough and cracked. In order to avoid these phenomena, 0.2% of boron-based water soluble fertilizer can be sprayed after planting the seedlings, which can effectively avoid this situation and thus improve The quality of celery.
The above is about the introduction of celery winter planting. As an off-season vegetable, it has a lot of profit, so in order to ensure the high yield of celery, these points must be managed. For winter celery cultivation, you have more Do you share good management skills?
