بررسی کارایی پوسته برنج به عنوان پوشش بستر کاشت قلمه در تولید نهال توت

In order to study the use of efficiency from different covers for nursery bed in production of mulberry sapling , an experiment was performed for 3 years. This experiment was carried out using as randomized complete block design with eight treatments and four replications. Treatments were rice husk in three thickness 4, 6 and 8cm, clear and black plastic covers , wood packing in thickness 8cm and two uncovered treatments with herbicide and without herbicide (control ). The percentage of rooting cuttings percentage, good sapling (sapling with the height more than 1m) and the rate of weed growing in mulberry cutting nursery were investigated in this research. The results showed that effect of treatments on weeds wet weight in first and second weeding out and percentage of rooting cuttings in three years is significant at %1 level. In the case of percentage of good sapling only in second and third years the significant effect was observed at %1 level. Clear and black plastic treatments with the highest percentage of rooting cuttings and the production of good sapling ( sapling with the height more than 1m) and acceptable control of weeds can be considered as the best treatment and control treatment with the highest weed growing and the least percentage of cutting grasping was considered as unsuitable treatment . Although rice husk in more thickness, wood packing and also the use of herbicide could decrease of weed growing to some extend but they prevented from cutting growing too.
