Bulk Buy 15 Cell Seed Starter Tray

When the celery seedlings grow to a height of 5 to 6 cm(black plastic nursery pots), the upper leaves are cut with scissors, and only the core of about 1 cm above the substrate is left to grow. During the whole seedling period, 1 to 2 times of flattening can be carried out to promote root growth and prolong the seedlings. Growth time, so it is necessary to plant in advance and calculate the seedling time. Celery requires a large number of colonies per 667 m2(10 gallon nursery pots wholesale), and the seedling leaves are tender and require more labor and more standard technical colonization.

(bulk buy 15 cell seed starter tray)But at the same time, when the temperature in early spring is low(plug trays wholesale), if the physiological seedling age of celery seedlings is 4 to 6 leaves, the night temperature after planting should not be lower than 10 °C for a long time, otherwise it is easy to cause celery convulsions. 7 to 10 days before the celery seedlings are planted, the wind content of the wind is controlled at about 50%(20 gallon nursery pots wholesale), the greenhouse temperature is kept at 15 to 17 °C during the day, 12 °C during the night, and 3 days before the planting. It can be reduced to 0~5 °C for refining.

At the same time, in the early stage(plastic nursery pots), it is necessary to cooperate with techniques such as kneading finishing and bottom fertilizer application. Therefore, the experimental research of the Agricultural Technology Extension Station shows that the traction type 2ZB-2 type cup-type transplanting machine can simultaneously perform watering, film laying and laying drip irrigation pipe, with high efficiency, suitable for large-scale vegetable planting in open field; electric self-propelled The type 2ZB-2 transplanter can easily adjust the row spacing of the plant, but it can only run for 4 hours (hours) when fully charged(14 gallon nursery pots wholesale). It has a compact structure and is suitable for greenhouse operation.

According to the technical characteristics of the existing planter, the plant height of celery should be controlled at about 15 cm, and 72 holes should be used for the trays(15 cell propagation trays wholesale). When the number of holes in the tray is large, the substrate of the seedlings is small, and the seedlings are easy to transplant when mechanically transplanted. Dumping affects the colonization effect.

The seedling water and fertilizer are supplied together(plastic nursery pots wholesale). This method can automatically classify the seedlings through the plug tray, effectively avoiding the impact of rainwater on the seedlings, and reducing the occurrence of soil-borne diseases. The strawberry seedlings are robust and disease-free, the root age is suitable, and the survival rate is high. The trial was successful and the next step will be to promote large-scale in various townships. After the strawberry seedlings are slowed down, it is necessary to strengthen the management of water and fertilizer(15 gallon nursery pots wholesale), control the red spiders and aphids in the early stage, and control the powdery mildew in the middle and late stages.

(bulk buy 15 cell seed starter tray)Through the combination of fertilizer and water automatic drip irrigation technology(plastic nursery pots manufacturers), strong seedling technology, disease PCR rapid detection technology and anthrax drug control technology, the cultivation of high quality strawberry seedlings under open air conditions is better achieved, and the secondary mother planting technique and delayed cutting are adopted. The combination of technology can effectively improve the quality of strawberry plug seedlings, reduce the cost of seedling mother plants, improve the design of traditional fertilizer drip irrigation system(21 cell propagation trays wholesale), and realize the low cost, high efficiency and stable automatic supply of fertilizer and water.
