Weeds should be removed outside the nursery shed in time and sprayed evenly on the nursery substrate to meet the requirement of water discharge(15 cell seed trays). The nursery should be built in a place with convenient transportation, flat land, open land, no water accumulation, and water and power sources(injection molded nursery pots). Before plant cuttings, all facilities and equipment should be thoroughly disinfected, including seedling sheds, seed beds, substrates, plug trays, tools and the surrounding environment.
(fabric 1 gallon grow bags manufacturers russia)The surrounding environment should be clean and free of pollution sources such as garbage dumps and sewage outlets(21 cell seed trays). The location should be far from factories and villages, and maintain a certain spatial distance from ordinary vegetable fields. Should comply with the relevant provisions of "GB / T18407.1 Agricultural Products Quality and Safety Non-pollution Vegetable Production Environment Requirements"(2 gallon pots). The substrate is covered with plastic film 1 ~ 2d.
Each 1m2 can be sealed in a closed shed with 1% 2d of 40% formaldehyde 10mL + 5g potassium permanganate mixed gas, or 5 to 10g sulfur closed fumigation 1m2 per 1m2(32 cell seed tray). You can also choose to spray a wide range of mixed aqueous solutions of fungicides and pesticides (such as carbendazim and phoxim). The seedbed and ground in the nursery site shed should be kept clean and free of pollution and weeds(3 gallon pots). Lime can be used for disinfection.
The trays, scissors and blades used for seedling cultivation should be cleaned and immersed in 2000 times solution of potassium permanganate for 10 minutes(50 cell propagation trays), or immersed in 1% ~ 2% sodium hypochlorite aqueous solution for 30 minutes to disinfect(5 gallon pots). The disinfected utensils in the nursery shed must be rinsed with clean tap water and air-dried to evaporate all the attached water before use, and prevent the occurrence of diseases in red seedlings.(fabric 1 gallon grow bags manufacturers russia)

In order to cultivate seedlings with good growth conditions and robust plants, it is recommended that the substrate ratio of cuttings is: peat, perlite, vermiculite = 3: 1: 1, and 10% ~ 15% fully-fermented organic fertilizer is added(1 gallon pots). Red broccoli cutting seedlings should be prepared with a loose, finely divided, porous, organic-rich substrate with a pH between 6.0 and 7.5.
