Polybag, then written polybag, is a plastic bag with holes that are usually used as media containers where the plant seedlings grow
Polybag size is very varied. Starting just as big as your thumb finger (for sausage container, very small seedlings), until the segede gaban (for container of seedling durian montong that even already bear fruit).
The thickness of polybag plastic also has many kinds, ranging thin as thin as onion skin, to the thick as a leather jacket.
As for the quality of polybag plastic, there are three classes. Class A, AD class and ST class.
Class A is the best, the most moderate and fragile ST AD, usually from recycled plastic.
Polibeg class A plastic characteristics soft, evenly thick, smooth smooth surface, shiny, no spots, clay, no smell of zinc, and the price is more expensive.
Polygb of recycled plastic features: the smell is stinging, if it seems uneven thickness, spots, fragile, easily torn, and the price is cheap.
Currently the price of polybags in the city of Kisaran, Asahan, A quality Rp.23.000 / kg, AD quality Rp.21.500 / kg and the ST Rp.20.000 / kg. Price is valid for 1 bales @ 25 kg purchase.
Well, now, what is the criteria of choosing a good polythe for the seeds we will make?
Good type of polybag is determined by the type of plant seeds that will be embedded therein. Suppose to make baby palm, or small palm seed leaves 3-4 strands, then the good is polybag size 12×17 cm, thickness 0.18 mm-0.20 mm, class ST. Baby palm takes only 3.5 months before transferred to larger polybags, such as size 30×35 cm or 35×40 cm.
Thickness and class of polybags need not be good because ST-class polibags usually last for 7-8 months.When transferred to a large polybag, the selection of polybag back is based on the length of time the seedlings will be planted. If for example the planned seeds of oil palm will be planted at the age of 1 year or more, then wear A class of polybags, size 35×40 cm. If the age between 8-11 months, then the choice of AD class with size 30×35 cm is the most proportional.
That was polybags for plant seedlings rooted in fibers. What about polybags for seedlings rooted riding?
We take rubber seedlings aliases aka the hull. When planned rubber seedlings will be planted when one or umbrella umbrella two, then wear polybag class A size 17×25 cm. But if it will be planted in the umbrella phase 3 or more, then polybags class A size 17×30 is a good choice.
Rubber trees prone to wind, especially the varieties of GT. Therefore, try to keep the root of the stump has not been too much when planted into the field. The rupture of the riding root occurs because the root has penetrated the bottom polybag.
In addition to its length or height, the selection of polybags should also take into account the size of the width. Polibeg will be arranged tightly, so that if the size of the width is too narrow, then the plant seeds will grow skinny towering, unsightly eyes, due to growing space that is too crowded.
The polibeg is basically, the bigger the better. But must also be taken into account the extent of seed breeding land, and transportation.
For example, year-old oil palm seedlings in a 35×40 cm polybag (weight 14 kg average) only fit 425 stems if transported by Colt Diesel truck six-wheel standard or equivalent. If polibegnya size 30×35 cm (average weight 7.5 kg), it can be loaded up to 800 stems. For long hauling, the difference in the number of payloads has greatly affected the cost of transporting the trunk.
