One of important equipment in reforestation or tree planting is a pot for mulching tree saplings. Originally pots were made of clay but they were too strong. When the trees grow up the pots must be smashed in order to let the roots and the stems grow up. Plastic pots are a popular alternative to be potted tree saplings due to their longer usability flexibility keeping and easy cleaning. In addition they are light and easy to move or transport. Typical pots usually have holes at the bottom which make poor ventilation that caused the slow tree saplings growth. Pots with holes in the side let the air comfortably flow and the roots do not go to the bottom of the pot. When the pots are moved the tree sapling roots are not ragged this help reducing the mortality rate of tree saplings. To Construct and find out the efficiency of plastic pot injection molded with 7.7 cm. in size 8 cm. high 0.10 cm. thick and the weight of 20 grams in the specification form the work-piece can be injected. For Construction and finding out the efficiency of holes for putting the plastic pot injection molded with 41 cm. wide 51 cm.long0.20 cm. thick and the weight of 330 grams in the specification form every work piece can be injected. There are 18holes for putting the plastic pot and all 18 holes are in the same size. Asst. Prof. Prasong KanKaew

The purpose of this thesis were: 1) to develop skills practice sets with a Macramé plant hanger for students with learning disabilities. 2) to examine the effect of using a Macramé skills practice Kits to make the Macramé plant hanger for students with learning disabilities. The sample group were 3 students with learning disabilities in home economics department Saowabha Vocational College. The instruments used in this research were student behavior observation forms Expert interview and Macramé skills evaluation forms. The findings revealed that: 1) Practice sets for Macramé work with Macramé plant hanger for students with learning disabilities had 2 sets with 8-10 patterns. Which skill training set A consists of Macramé methods handouts and the skill training set B consists of Macramé methods video. 2) The results of the study were the 1st student can be used the both sets. Which they were finished their works in time and had a good quality Macramé work pieces. And the 2nd and 3rd students can be used the skill training set B to be made work pieces with correct pattern more than the skill training set A set.

The effect of azimuth and pot color on the variation of pot surface and growing media temperature was studied. Four pot colors that including with black brown silver and white color were used. The growing media comprised with soil : rice husk : coconut dust at 1:1:1 ratio. From the result of this study the azimuth and pot color effected the variation of pot surface temperature. The azimuth effected the variation of pot surface temperature at 8.00 10.00 14.00 and 16.00. At 8.00 and 10.00 pot surface temperature in east direction was the highest while at 14.00 and 16.00 pot surface temperature in west direction was the highest. Whereas pot color effected the variation of pot surface temperature at 8.00 10.00 and 14.00 with black color was the color that had the highest 33.3 39.1 and 46.4 C respectively. On the other hand the white color was the color that could the highest reduces the pot surface temperature when compared with the temperature of black pot color which were 4.6 3.9 and 4.3 C lower than that in a black pot respectively. Not only the effect on the variation of pot surface temperature pot color was also affected on the variation of growing media. Pot color effected the variation of growing media temperature during 8.00 to 18.00. When compare the growing media temperature among the pot color with that in black pot color which was the highest temperature white color pot was the highest efficiency to reduce the growing media temperature especially at 10.00 and 12.00. White pot color could reduce the growing media temperature about 5 C follow by silver color pot was about 3 C while the growing media temperature in brown color pot was not difference with that in black color pot
