"Let me introduce the rubber trees and banana trees that are common in Cambodia, these two trees are also very common, although they have not reached the status of Cambodia's national tree, but they are also the symbol of Cambodia!"

"Native to the Amazon forests, the rubber tree is a deciduous tree with milky sap, which requires more average annual precipitation and is suitable for growing in deep, fertile and moist acidic sandy loam soils with good drainage. ”

"The growth life span is about 60 years, this kind of tree has a long lifespan, there is an ancient Chinese saying that the predecessors planted trees, the descendants enjoyed the shade, the predecessors planted trees, it is really the descendants of the shade, this kind of tree is planted in the previous generation, and the next generation will enjoy the blessings. ”

"The word rubber tree, which comes from the Indian word for 'tree of tears', gives its name to the milky white sap that flows out if you carefully cut the bark. ”

"In the prehistoric period of rubber, it was simply mined and exploited only by the Indians of South America, and in the beginning, rubber may have been used as a treasure or an extremely valuable item. ”

"The rubber tree is very tall, up to 30 meters high, abundant**, with a pointed beak at the top, slightly concave at the base, thin exocarp, reticulate veins after drying, thick and woody endocarp, and the seeds are oval, pale grayish-brown with markings. ”

"Rubber trees like high temperature, high humidity, quiet wind and fertile soil, need to grow in a place with a higher temperature, not cold-tolerant, cold countries like Russia can not survive, suitable for deep soil, fertile and moist, well-drained acidic sandy loam growth, shallow roots, fragile branches, poor adaptability to wind, susceptible to wind cold and reduce rubber production. ”

"The gardener who plants trees must have a clear understanding of the varieties and preferences of various trees, as well as the external conditions suitable for their growth. ”

"Oh, that's not bad, Mom, please be my tour guide these days, I found that your personal knowledge system is still very rich!" Zhou Sen praised Xiao Yang.

Xiao Yang smiled, "You praise me, I know a little bit of everything, commonly known as the golden oil, my uncle likes to learn, he has educated me since he was a child, there are mountains outside the mountains, there are people outside the people, to be low-key and humble, to ask for advice like a knowledgeable person, plus I usually like to make friends, no matter what industry my friends are engaged in, I like to socialize, gardeners, chefs, have my friends, I have been in contact with them for a long time, I have heard and seen, I have seen more, I have heard a lot, I have learned a lot of knowledge." ”

"Your method is very good, there is also a saying in China, called 'threesomes must have my teacher', I also agree with this sentence!"

"This tree is planted in Indonesia, Thailand, Malaysia, China, India, Vietnam, Nigeria, Brazil, Sri Lanka, Liberia and other countries, and Southeast Asian countries are the most widely cultivated, the most rubber, Malaysia, Indonesia, Thailand, Sri Lanka and India and other countries, the rubber area and rubber production account for 90% of the world, China's rubber planting area is mainly distributed in Hainan, Guangdong, Guangxi, Fujian, Yunnan, Hainan is the main rubber planting area. ”

"The biggest use of rubber trees is to produce rubber, which is a major industrial raw material in Southeast Asian countries, and it is still widely used to produce economic value, so many tree farmers are willing to plant it. ”

"It is not easy to plant a good rubber tree, starting from planting seedlings, it is necessary to invest a lot of energy and time, when planting, the seedlings should be placed in the center of the planting hole, the plant should be perpendicular to the ground, the depth of planting, the bud joint pile is 2-3cm above the ground below the bud joint, the bagged seedlings are maintained in the original position, and the high rod bud seedlings are appropriately planted deep to bury the joint point into the ground. ”

"It is necessary to return to the soil, layer compaction, cover grass, water, drought-resistant planting, fertilization of rubber gardens, pest control, trees and people, sometimes not well planted, but also sick, but also to cure the disease and save the tree, insecticide and insecticide, tree farmers are very hard, hard work, in order to cultivate saplings, saplings grow little by little, in order to grow into towering trees. ”

Zhou Sen was very curious and asked Xiao Yang: "How do rubber trees produce rubber?

"The main raw material for rubber trees to make rubber is natural rubber, natural rubber is made by the rubber tree when the rubber tree taps the latex through coagulation and drying, Cambodia is relatively backward, basically with people and workers to cut, of course, there are tools, so it is easier to operate. ”

"Natural rubber is widely used in industry, national defense, transportation, medicine and health and daily life because of its strong elasticity and good insulation, plasticity, water and air insulation, tensile resistance and wear resistance, etc., and is widely used, and these fields are closely related to human daily life. ”

"Rubber can be used to make tires, for example, we are most familiar with the production of car tires, there are so many cars in the world that need tires, the production of tires need rubber, this material, can not be replaced by other materials, the elasticity and flexibility of rubber is very good, wear-resistant, and can move on the ground for a long time, with tires, cars can run, human cars, but also save a lot of effort. ”

"In addition to rubber trees, oil extraction from seeds can also be used as raw materials for making paints and soaps, rubber husks can be used to make high-quality fibers, and husks can be used to make activated carbon, furfural, etc. ”

"The wood material is light, the pattern is beautiful, the processing performance is good, and it can be used to make high-grade furniture, fiberboard, plywood, pulp, etc. after chemical treatment. ”

"When it comes to furniture, the furniture made of rubber trees is still very beautiful, because the rubber tree comes with a pattern, it looks very good, and then sent to the factory, painted by the workers, the furniture made is very beautiful, in Thailand and Cambodia, teak, rubber tree wood, to make furniture are very economical and practical, cheaper than mahogany, and firm, durable, so buy wood and furniture from Southeast Asian countries, there is still a broad market. ”

"In addition, rubber plantation is a sustainable tropical forest ecosystem, a pollution-free and renewable natural resource, and the best system to replace low-quality and inefficient tropical shrub and grassland ecology with rubber plantation ecology. ”

"The forest cover dominated by rubber trees has created a good environment for green environment, water conservation, soil and water conservation, and sustainable development, which not only greatly improves the forest coverage rate, but also improves environmental conditions. ”

Zhou Sen nodded, "Human beings and nature are peaceful coexistence, nature has an ecological environment, we must strive to protect such an ecological environment, can not artificially destroy the ecosystem, we must learn a lesson, if the ecological environment is destroyed, a large number of indiscriminate felling, reduce trees, will affect the weather, some areas are dry and short of water, the wind and sand are too large, easy to desertification." ”

"The northern region is dry, Southeast Asian countries are very close to the sea, the climate is hot, warm and rainy, this is the advantage of Southeast Asian countries, but also to make reasonable use of natural resources, especially Southeast Asian countries are the main force in the export of rubber, most of the world's rubber is produced in these countries, there are advantages!"

Xiao Yang nodded in agreement, "Yes!"
