Spring celery sowing cultivation points
The seedling stage of spring sowing celery is cool, the temperature is low, and it is in an environment conducive to flower bud differentiation. In the future, long sunshine conditions are prone to convulsions in advance. Therefore, it is advisable to choose Beijing Boler spring celery and Tianjin Baimiao celery, etc. that are later in season. 1. Open spring celery spring celery can be exposed live lake seedling transplanting (1) seedling sowing 1 Live direct exposure: Generally, after the winterization of the soil, the average daily temperature of about 5°C can be used to germinate and sowing. The seeding rate per mu is 0.75 to 1?. Live spring celery due to early sowing, low temperatures, most of them will occur early convulsions, so the short growth period (70 to 90 days), in the management of special attention to seize the fertilizer, water management, promote vegetative growth, delayed spawning , harvesting when the stem is younger. 2 Seedling transplanting: In order to supply spring celery earlier, increase yield and improve quality, protect seedlings can be used for protection, such as solar greenhouses, Yangshuo improvement, Yangyang picking, etc., sowing time is generally from late January to late February and late March. Planting is scheduled for April, and the market can be harvested from late May to mid-June. Pay attention to sowing cover soil should be a little thin, about 0.5?, pay attention to moisturizing, pouring enough bottom water, sowing after the cover film, keep the bed temperature at 20 ~ 25 °C, in order to facilitate the excavation, the seedlings Qi timely cooling, keep cool and moist, Temperature 18 ~ 20 °C, seedling age 50 ~ 60 days. (2) Field management planting seedlings from 10 to 15 square meters, single plant or 3 to 5 plants per hole, individual plant can be slightly denser, due to the shorter growth period of spring celery, small growth, prone to premature boring, so appropriate Close planting depends on the group's increase in production. Apply sufficient organic fertilizer before planting. Maintain a certain temperature in the initial stage of planting. Strengthen the cultivator, increase the temperature and promote rooting, reduce seedling growth, and start growing after easing seedlings. Strengthen water and fertilizer management and promote vegetative growth. Delayed flower buds. 2. Plastic shed spring celery varieties selection, sowing the same with the previous period, generally in early January to late January, solar greenhouse or Yangshuo nursery, planting in late March, 20 to 25 days before planting, buckle cover film and small arch shed, And apply good fertilizer to improve the ground temperature, remove the small arch shed film when planting, break the membrane in the pod to open the hole planting, 2 to 3 plants per hole, the planting hole should not be too large, planting not too deep. After planting watering, it is best to cover the straw slats at night to cover the heat and cold. It should try to avoid the conditions below 13°C for a long time. Otherwise it will promote the differentiation of flower buds and cause the convulsions in advance. The sunshine time of celery can also prevent the formation of flower buds. The celery begins to grow to meet the supply of fertilizer and water, promote growth, and provide the morning market.
