The operation of growing seedlings in a box consists of different stages. Among the soil suitable for growing box seedlings, the most important characteristics of a good soil for a seedling box are suitable acidity (PH), medium texture with sufficient organic matter and water retention capacity. Clay loam soil (clay mixed with loam and plant material) which is the most suitable soil for this purpose.
The amount of soil required for one box is about 5 kg. The depth of the soil bed in the seedling box should be 2 cm, and the thickness of the soil used to cover the seeds should be 0.5 cm.
Cleaning and drying the soil by collecting the soil 2 to 3 months before sowing, adjusting the PH (acidity) of the seedbed soil, using fertilizer in the seedling breeding box, preparing high-quality seeds in rice, selecting seeds using weight. Especially, disinfecting seeds, soaking rice seeds, accelerating germination, which sufficient measures to accelerate germination before sowing, causes uniformity in seed germination, which is a good start for the growth of rice plants, and also Seeding operation, filling the seed boxes with soil, irrigation of the boxes, seed amount, management of seed germination in the growth chamber, initial greening, preparation of the vault in the main land and transfer of the seedling boxes to the vault, preparation of the vault bed, Placing the boxes in the bed of the treasury is one of the other stages of growing rice seedlings in boxes.
The main difference between mechanized and traditional rice cultivation is in transplanting, transplanting and harvesting, which in the mechanized system, machines have replaced human labor in these stages. The purpose of mechanized rice cultivation is to reduce the difficulty of work, regular and geometrical planting in such a way that the desired plant density per unit area is provided, increase yield and achieve macro management.
