Starting from the tail of the potato pieces, the seeds are cut in a spiral shape(50 cell seedling trays wholesale). The top is divided into two. Make sure that each cut has 1-2 top sprouts, and the cuts must be uniform.
(plant germination trays manufacturers vietnam)At the same time, the planting period of suitable land cultivation mode in Tianjin is generally from mid-March to early-April(nursery plant pots). Generally, the weight of each seed potato is about 25 grams, and the cutting tool is 75% alcohol. Strict disinfection. Growth is robust and rapid at 18 ° C. Seeding is possible when the local temperature is stable at 5 ° C(6 cell propagation trays wholesale). When planting, use an opener to punch 8-10 cm deep colonies depending on the row spacing hole.
It takes about 120 kg of seed potatoes per 667 square meters(square grow pots). Medicinal treatment, put the cut potato pieces into 0.01% boric acid or 500 times 50% carbendazim solution, soak them for 5-10 minutes and then drain and drain to dry. Move the dried potato blocks to the warm and sunny place for 3 to 5 days. Maintain a temperature of about 15 ° C to allow the young shoots to grow green(18 cell propagation trays wholesale). During the planting period, the black potato shoots started to germinate when the temperature exceeded 5 ° C.
Premature. Seedlings are susceptible to freezing damage, and they cannot be marketed early, which affects planting efficiency(wholesale nursery pots). High mulch mulching, double-row cultivation High mulch mulching can increase ground temperature 3-5 ° C, and early planting period is about 15 days(8 cell propagation trays wholesale).
