Rubber into Thailand rubber tree
was planted in the country. Since the name "Siam" is that it is the latter period of 2425, which was expanded from the seeds they plant 22 trees to plant rubber in the countries of Asia. The evidence is clear that since 2442 the prince made Ratsadanupradit Mahisorn loyalty (neck Sim Bee Na Ranong) is the same one. "Father of the tires," who had planted rubber trees on the province's first Kantang == then. Prince Ratsadanupradit invention. Sent to a rubber plantation to teach the people. Your students that they are all true and the village was the ruler of sheriff. At the same time he ordered the village headman of the tires were distributed. And encourage farmers to grow online. Which at that time. It can be said that the rush of rubber and was the rubber that it "rubber Tesa" Later, people used to grow the plantations more and the expansion of plantation rubber in the southern provinces of 14 provinces =. = from Chumphon to the provinces that border Malaysia.To date, Thailand has a land area of about 12 million hectares of rubber and are scattered in the South East and Northeast, a new rubber plantation development of the country's rubber industry. Has continued to make progress in a country that most tire manufacturers and exporters in the world.
Every time the government has focused on developing a rubber throughout. Has set up agencies responsible for research, development and technology transfer. Including grant aid for planting rubber varieties.
Rubber plants.
1. A species - high yield - good growth - are appropriate for the area - in areas where the disease has a very serious problem.
