Celery is a common vegetable variety in our life. Besides the common open-air celery cultivation, do you know the cultivation techniques of celery in the greenhouse in autumn and winter? The so-called solar greenhouse autumn and winter celery, that is, early autumn (late August to early September) seedlings, late autumn (late October) planted, harvested celery before the Spring Festival. The current low-yield cultivation techniques of Huinong.com are described below.
First, the selection of good varieties
The main varieties of celery can be selected from "Kaifeng Glass Crisp", "Jinnan Cing" and "American Celery".
Second, sowing seedlings
1. Selecting a seedbed
It is convenient to choose irrigation and drainage, loose soil, fertile loam or sandy loam. Generally, every 0.1 mu of seedbeds is applied with 300 kg to 500 kg of organic fertilizer, 2 kg to 4 kg of urea or other fine fertilizers, and finely prepared for planting.
2. Seed treatment
Soak the seeds in cold water for 12 to 24 hours. After picking up, rub repeatedly with your hands, smash the waxy outer skin, place it at 15 °C to 20 °C, sprinkle and moisturize twice a day, wait until 50% of the seeds are white. .
Celery is a cool, humid climate with semi-cold-resistant vegetables; it is not resistant to high temperatures. Drying can withstand low temperatures below short-term zero.
Third, the requirements for environmental conditions
1. Temperature: Celery is like a cool climate, and the growth temperature is 16 to 22 °C.
2. Illumination: The vegetative growth stage of celery is not strict with the illumination requirements, and the illumination intensity is low. Under weak light conditions, it can still grow normally.
3. Soil: Celery is suitable for growing in sandy loam rich in organic matter.
4, water and nutrients: celery like wet, so in the cultivation to keep the soil enough water; need a large amount of fertilizer, but because the root absorption capacity is weak, so in the cultivation to apply enough base fertilizer, and timely topdressing To meet the demand for celery for nutrients.
The above is the cultivation technique of the celery in the solar greenhouse in autumn and winter, which is compiled by Huinong. I hope to help everyone.
