The precision seeding machine mainly has two kinds of mechanical rotary type and vacuum air suction type(plastic nursery pots). The mechanical rotary type requires strict seed shape, the seed needs to be pelletized before it can be used; the vacuum air suction type does not require strict seed shape, and the seed does not need to be pelletized. Most of the currently used trays are 54.9cm × 27.8cm, and each seed tray has 50 to 288 holes(18 cell propagation trays wholesale). The most common ones are 72 holes, 128 holes and 288 holes.(buy cheap plastic bonsai pots online)
The tray seedling substrate mainly includes peat, vermiculite, perlite, dried chicken manure, and oyster mushroom residue(plastic nursery pots wholesale). Peat is best to use gray fresh grass charcoal, Ph5.0 ~ 5.5, good hydrophilic performance. The matrix formula suitable for winter spring vegetable seedlings is vermiculite: grass charcoal = 1:2 or oyster mushroom residue(12 cell propagation trays wholesale); grass charcoal: vermiculite = 1:1:1. The matrix formula suitable for summer seedlings is peat: vermiculite: perlite = 1:1:1 or peat: vermiculite: perlite: 2:1:1.
Everyone knows that the benefits of facility nursery are not only reduced, but also reduce the labor intensity(black plastic nursery pots). It is suitable for long-distance transportation and entry into the circulation field. At the same time, the seedling process can control the release and disinfection of diseases, and reduce the occurrence of pests and diseases in the seedling stage. The erection of sports seedlings improves the utilization of space(8 cell propagation trays wholesale); the most important thing is that the quality of facility nursery is better than that of conventional soil seedlings. Then the author will first introduce what is soilless seedlings?
(buy cheap plastic bonsai pots online)It is also one of the methods of facility nursery(plug trays wholesale), which refers to the use of natural or artificial synthetic substrates and nutrient solutions such as vermiculite, peat, perlite, rock wool, or the use of hydroponic and aerosol culture for seedlings without natural soil. Also known as nutrient solution seedlings, generally 50 ~ 70cm. The vegetables used in daily use are free of soil seedlings(6 cell propagation trays wholesale). According to the different application equipments and main technical specifications, they are generally divided into two types: rapid seedling cultivation and seedling raising.
Knowledge of facility nursery technology can be found in: Facility nursery technology: one of the common vegetable seedling methods(plastic nursery pots manufacturers). The basic procedures for rapid seedling cultivation of the new method of rapid seedling raising techniques include five stages: seeding, seedling emergence, greening, seedling formation and seedling formation. The seedling substrate is a substance used to fix the root system and support the growth of the seedling(4 cell propagation trays wholesale). The nutrient content is high. The main materials are sand, slag, carbonized rice husk, vermiculite, perlite, and peat.(buy cheap plastic bonsai pots online)
Fertilizer water supply system: using micro-spray equipment, automatic water spray fertilizer(wholesale nursery pots). Nursery bed frame: The size of the bed frame is convenient to place the trays, and it is better to make full use of the facility area. The height of the bed frame can be determined according to the needs. Peat and vermiculite themselves contain a certain amount of large amounts of elements and trace elements, but still can not meet the needs of most vegetable seedling growth(24 cell propagation trays wholesale). When preparing the substrate, a certain amount of chemical fertilizer should be added, and the amount of chemical fertilizer used in seedling cultivation should be added.
