Good quality, strong disease resistance, not easy to get sick(cell trays), high resistance to leaf blight, rust, high disease resistance to root rot and stem blight, suitable for greenhouse and open planting. The substrate is made of loose, fertile, water-storing and fertilizer-preserving commodity matrix. Before the substrate is loaded, add appropriate amount of water mixed with carbendazim(72 cell propagation trays), fully stir and then plate, on the matrix and The trays have a disinfecting effect.(best shallow microgreen germination trays)
A 32-hole plug was used to pour the water(plastic nursery pots manufacturers), and the substrate in the plug was pressed out of the seeding hole by a mold, and artificially sown. Covering the substrate with a thickness of 1cm or more after sowing, it can maintain good gas permeability and water retention, and can ensure that the asparagus seedlings do not fall after emergence(200 cell seed starting trays). The sowing time of asparagus spring seedlings is in late March and early April, and the greenhouse temperature is preferably 15~25 °C.
Before planting(plastic nursery pots), it is necessary to check whether the heat preservation and ventilation measures of the nursery greenhouse are in place to prevent problems when needed, which may cause the temperature in the greenhouse to be too high or too low to affect the growth of asparagus seedlings(72 cell plug trays supplier). The germination is carried out in 3 steps: the asparagus seeds are repeatedly washed in warm water, and the water is continuously washed until the color of the water is no longer turbid.
(best shallow microgreen germination trays)It is not easy to absorb water, but asparagus can be planted in open air and planted in two ways(wholesale nursery pots). The 1000-grain weight is 25g, the budding rate is 80%, and the seedling volume of 500g seeds is about 16,000. The main components are charcoal, vermiculite and perlite. The white roots should be lightly handled and try not to break(128 cell plug trays supplier). The asparagus seed coat is hard and has a thick layer of wax. Around 4d, when 35% of the asparagus seeds are white, they can be sown.
The asparagus seedlings and cultivation techniques are concentrated in the membrane-free greenhouse without soil trays(plastic nursery pots wholesale). The variety is green asparagus. The asparagus seeds are immersed in warm water of 55~60°C, which has the function of disinfection and sterilization, and the water is changed every 4 hours(128 cell seed trays wholesale). Soak for 2d, put the net bag into the incubator (temperature 25~28 °C, humidity 80%~90%), take out the net bag every morning and evening, and clean the seeds for ventilation.
It must be soaked in germination to sow(32 cell seed starter trays). The actual sprouting rate will show different results depending on the temperature and humidity of the nursery greenhouse. Asparagus seeds emerged about 10 days after sowing, the humidity should always keep the substrate moist, the temperature is best at 20~25°C, and the sprouting rate is 75%(seed starting trays supplier). The temperature is 25~30°C, about 5d, the sprouting rate is 60%, the temperature is 30°C, the sprouting is fast, but the budding rate is low.(best shallow microgreen germination trays)
The temperature and humidity in the nursery greenhouse should be controlled before the asparagus emerges(black plastic nursery pots). About 10 days after the emergence of asparagus, when the plant height is 3~4cm, spray 70% of the 100% carbendazim solution to prevent rickets. When the second stem is produced around 15d, 0.2% trace element fertilizer is added(32 cell plug trays supplier). In the drought and high temperature, pay attention to the control of aphids, you can use 50% pymetrozine 75g / hm2 spray control.
