With the warming of the climate, the prospect of tropical fruit trees is promising, but farmers must be patient from planting seedlings to harvest. According to the way of planting, it takes 2 to 5 years for golden fruit to bear fruit, 3 to 6 years for durian honey to be harvested, and 2.5 to 6 years for rambutan to be harvested. Even after some farmers have planted saplings, they do not expect a single fruit to be planted for 10 years with longer ─ planting time and increased harvest variables, and no one can guarantee the economic value of future fruit trees.

Liu Bijuan, an associate researcher at the Fengshan Branch of the Agricultural examination Institute, said: "are the farmers who planted these new things pioneers or martyrs? He is likely to fail and is at great risk. " Due to the uncertainty of the adaptation of emerging fruit trees to the environment, farmers are currently planting a large number of trial plants. However, there are not too many diseases and insect pests, little need for pesticide spraying, and low-level manual work, which attract many retired silver-haired people to plant or the general public to activate idle land use.

Yen Chang-Rui, a professor in the Department of Agriculture at the University of screen Science and Technology, analyzes that compared with extensive operations in Thailand, Indonesia, and Malaysia, cultivation management in Taiwan is more sophisticated, such as sparse fruit to retain fruits of better quality, and there is also a period of adjustment to face market supply. Taiwan farmers and research institutions continue to improve varieties and technology, and the fruit is large and sweet. "this is also the reason why our varieties and cultivation techniques are almost adopted in Southeast Asia and the mainland."

To maintain better varieties, improve survival and shorten the infancy of fruit trees, Yan Changrui suggests grafting propagation, such as rambutan and durian honey. "the golden fruit can be planted with seedlings, and the seeds will bear fruit in about a year and a half to two years, but there will be some variation, which is an acceptable range."

Yen Chang-Rui also reminded farmers who are interested in trying to grow that because of the particularity of the industry, emerging fruit trees often become a tool for speculation among seedling merchants. "for a while I dared not hold a viewing party, because as long as it was held, the price of the seedlings would rise after a year, and the price of a tree had changed from 200 yuan to 2000 yuan. Fruit is fruit. Don't use it as a hype tool. Growers should also have this concept. There is no need to buy a seedling worth 2000 or 3000 yuan. " Before purchasing seedlings, in addition to doing a good job in homework and comparing goods, you can also obtain a small number of seedlings for trial planting from academic research institutions with high credibility, such as agricultural testing institutes, agricultural reform farms, or agricultural extension committees of colleges and universities.

Yan Changrui, a professor in the Department of Agriculture of the University of screen Science and Technology, extended the advantage of fewer diseases and insect pests and avoided a vicious circle.

How to maintain the advantage of "fewer diseases and insect pests" of emerging fruit trees is also a lesson given to farmers by the natural environment. Yan Changrui recalls that when he first began to study Honglongguo 30 years ago, there was no problem of diseases and insect pests, but now it is becoming more and more serious. "when farmers are under cultivation and management, they apply fertilizer improperly and spray too much, causing pests to develop resistance to pesticides."

Farmers who invest in new fruit trees should take precautions against using an appropriate amount of medicine. Yen Chang-Rui says: "in the past, many farmers sprayed medicine whenever they had diseases and insect pests, but now after propaganda, people may gradually know that ecological ── of diseases and insect pests can be better controlled as long as you grasp the right time to spray medicine." In recent years, industry officials have advocated farmers' friendly environmental farming, which is also conducive to new fruits from embarking on a vicious circle.

"We will also recommend these new fruits in organic cultivation, which are less harmful to diseases and pests and are easier to manage," Yan said. " Liao Junsheng adopts natural farming methods for the cultivation of golden fruit. He says: "every month, we have to spray chitin, actinomycetes, and Bacillus subtilis to carry out biological control. We control it at the front end, instead of spraying pesticides at the back."

Most of the emerging fruits are produced and sold by themselves, which is verified by the resume of the production and marketing class.

At present, the unit prices of durian honey, golden fruit and rambutan are high. Most of the emerging fruit manufacturers are self-producing and selling on the Internet, and a small number of fruits have entered the auction market. It is also a way to have market competitiveness and highlight the value of the products.

Promote the establishment of Golden Fruit and durian Honey "Taiwan good Agricultural practices (Taiwan Good Agriculture Practice, TGAP)" by the Agriculture and Food Department and the Agricultural testing Institute, which is the 31st class of fruit tree production and marketing in Chaozhou, Pingtung. Most of the 31 class members are retired public education staff. after a visit to the six tortoise orchards in Kaohsiung in 2010, the class members came up with the idea of planting durian honey and golden fruits. In order to improve the quality of fruit, the production and Marketing Class Association asked Fengshan Branch of Agricultural testing Institute to prepare TGAP. Later, durian honey and gold fruit followed the TGAP standardized operation process and mode of production, which were verified by the production and marketing experience of agricultural products.

"We also conduct agricultural observation and two large-scale agricultural cultivation studies every year." Luo Xiumei, a member of the class, mentioned that she would learn from other people's experience in the process of observation, and would also hire domestic scholars and experts to come to the production and marketing class to explain cultivation techniques.

Liao Junsheng's golden fruit channel is mainly based on online homestead, and his sales strategy is not to enter the market for wholesale and drive down the price of his own products. "We use the natural farming method with higher cost. When we get to the market, the price will be the same as that of the usual agricultural method, so we don't go to the market for sales. We'd rather not go into the market and sell it. We'd rather make vinegar and enzymes from bad or surplus fruits." It not only increases the planting cost, but also uses better material packaging to make the huge bright yellow fresh fruit appear in front of customers. Liao Junsheng's high-quality golden fruit house can be sold at least twice as high as the market price.
