The good helper of sustainable agriculture
Release time:

Lin, a researcher at agriculture and forestry university in fujian, China, has a lifelong passion for research. Since 1983, he began to study the use of herbaceous plants to grow edible fungi, and thus the technology of fungus. For more than 30 years, the fungus technology has been expanded to produce animal feed and fuel, and then applied to soil erosion control, and achieved remarkable results. At the end of may to the United Nations headquarters in New York held a seminar, professor of he Lin to introduce this technology to foreign diplomats, aimed at helping developing countries to develop sustainable agriculture. Here's the UN news.

On May 26, the UN economic and social affairs headquarters in New York held a seminar, end "the implementation of the 2030 agenda: strengthen developing countries through JunCao technical ability of sustainable agricultural development to reduce poverty and promote productive employment". The keynote speaker at the symposium was Lin, director of the institute of fungus grass at China's fujian agricultural and forestry university.

After the seminar, professor Lin briefed us on his original intention to study the fungus. Until the 80 s, he says, artificial cultivation of edible fungi is mainly use deciduous tree, he began to study in 1983 in wild and artificial planting herbs instead of hardwood cultivated edible fungus, the purpose is to solve the problem of forest resource restricted the cultivation of edible fungi. At the same time, the solar energy of the fungus is very high, and the conversion rate of the solar energy into the fungus is four to seven times higher than that of the broad-leaved tree, and the biological conversion rate of edible fungus is also higher. Since then, more than 30 years have passed, and professor Lin's research on the fungus has expanded to a broader range.

Lin: "the fungus is a new field. It is not just a grass, or a few grass. We choose 46 kinds of grass. At the earliest time, it was used as a fungus to grow edible fungus. Later, the research was further expanded and expanded to the poor feed of mycelia, which is a part of high-quality feed. It is then expanded into biomass energy to generate electricity and produce biogas. Also as biomass material, make pulp, plank. In recent years, we have extended it to ecological governance."

Seagrass technology was awarded at the international invention exhibition in Geneva and the Paris international invention exhibition, and was extended to other countries from the very beginning.

Lin: "we first cooperated with Japan in 1992, and Japan needs it. And then we worked with other countries, countries that were lagging behind, like in the tribal economies, like Papua New Guinea. We can simplify the technology and adapt it to the needs of local villagers, so as to make it easier for the local villagers to see it and do it as soon as it is done. So this technology can be used in the most backward countries and in the most advanced countries. We are supported by the ministry of commerce and the ministry of foreign affairs, ministry of science and technology, through the international cooperation in foreign aid built 10 , are in developing countries, such as in Papua New Guinea, Fiji, Malaysia, Thailand, Rwanda, South Africa, lesotho."

As early as in 1994, the fungus technology is described by the United Nations development program (undp) as of priority cooperation projects of China and other developing countries, but also by the Chinese ministry of foreign trade as advanced and practical technical training programs in developing countries. In rural areas of the developing world, whether it is growing edible fungus, or producing feed and fuel, it can help farmers get rich out of poverty.

Lin occupies the place: "produce sheet - we have a demonstration to swim in the Yellow River, this demonstration to plant oasis no. 1. In the case of mu, one mu of oasis can produce seven cubic meters of plate, and one cubic meter of plate is worth 3000 yuan, which is much higher than the current agricultural development.

In the past 30 years, a series of studies and demonstrations on the ecological management of the fungus have achieved remarkable results and opened up a new way for ecological governance, said Lin. He cites, for example, the high utilization of the fungus for water. The crop yields the highest crop yield is corn, which requires 4,500 tons of water to grow a hectare of corn and 4,500 tons of water to grow a hectare of mycelia, which produces three times the yield of corn.

Lin: "the first time we were in changting in fujian province, we solved the problem that had not been solved for several decades in three months. Later, the technology was developed in the nyingchi region of Tibet, and in the high and cold regions of the Brahmaputra river, at an elevation of 3,670 meters, the sand dunes that govern the flow of fungus were also successful. On the basis of this, then apply the JunCao ecological governance in la shan, in the middle reaches of the Yellow River la shan river 85 km long river flows into the river a few years ago the sediment reached one hundred million tons - now, of course, less - often have 8 to 10 levels of winds, the sand a year into rivers propulsion 8 to 10 meters, is China's four big sandstorm source one. In 2013, we managed the experiment there and succeeded. On the basis of this, we have continued to ordos, usually it is called the earth's environment of cancer, than arsenic sandstone of governance, this is a very special phenomenon, when it rains suddenly became a sediment flow into the river, like the SLATE is not long after the weather is fine. We combined the giant fungus and managed well. This year, we continue to move to the upper reaches of the Yellow River. Last year, we found some suitable methods for the restoration of vegetation on the upper reaches of the Yellow River.

Of he Lin, said professor country attaches great importance to the research and extension of JunCao technology, relying on the fujian agriculture and forestry university in 2011 established the "national JunCao engineering technology research center", in 2013 and set up the "JunCao comprehensive exploitation and utilization of technology national local joint engineering research center", and give the two innovation platform a lot of preferential policies, brought together dozens of science and technology talents. The centre is also continuing to develop some emerging powers and is looking forward to making the fungus play a greater role in promoting people in developing countries to get rich and to achieve sustainable agriculture.

Of he Lin: "I hope this year in the Nile basin nine countries use JunCao ecological management, to poverty alleviation, promote the development of the industry, let the people of all countries in Africa in the technology of our country. The fungus technology originated in China, but it serves the society and serves the world and mankind.
