GPIT technology in Yunnan province breaks through many world problems in agricultural production (7.2)

OA show ('918 '); Professor Na Zhongyuan, director of Yunnan Institute of ecological agriculture, after 10 years of concentrated research and invention of GPIT technology, is the first successful solution in the world to improve the photosynthetic efficiency of crops, which integrates stress resistance, early maturity, high yield, high quality and pollution-free as a whole, and is a leading new technology of biological genetic engineering in the world GPIT is the abbreviation of crop gene phenotype induction technology This technology can increase the ability of cold resistance, high temperature resistance, disease resistance and insect resistance of crops, improve the adaptability of crops, and achieve the effect of early maturity, high quality, high yield, stress resistance and pollution-free More than five years of limit test and production demonstration show that this technology breaks through the traditional theory of "gene phenotype can not be induced and regulated", and overcomes the problem of "photosynthesis efficiency greatly improved" which has puzzled many developed countries for many years The photosynthesis efficiency is increased by 50% - 400% At the same time, it is the only high-tech bioengineering without worries of genetically modified ecological pollution Technology In 1999, GPIT technology was used in 21 million mu crops nationwide, which solved several key problems in agricultural production - solved the problem that the warm loving crops in high altitude areas and cold and cool mountain areas could not resist the invasion of low temperature and cold damage As well as the problem that crops can't be precocious in the areas of low temperature and low accumulated temperature Zhongdian plateau dam area in Diqing Prefecture, Yunnan Province, with an altitude of 3276 meters, is considered to be a restricted area for crops other than highland barley, potato and spring wheat In 1997, the maize was planted in Zhongdian by GPIT technology The tolerance temperature of maize seedling was - 5.4c, and the surface temperature was - 9.5c The effective accumulated temperature in the whole growth period is 493 ℃, less than half of the world's recognized minimum limit of effective accumulated temperature of 1100 ℃, but the yield of 499 kg / mu is still achieved In 1999, this technology was used to plant corn in the logistics base of Lhasa armed police force at an altitude of 3658 meters, which was high-quality and high lysine corn The experiment and demonstration in Zhongdian, Lhasa, Hebei, Shandong, Heilongjiang, Jilin and other cold areas of Yunnan Province showed that the application of GPIT technology can shorten the growth period of crops greatly, shorten the average of 7-15 days for wheat, 10-20 days for rice and 30-40 days for corn - solved the problem of "high quality but not high yield, high yield must be polluted", and provided a new scientific way for high quality and high yield of crops The comparative experiment in Baoding City, Hebei Province shows that the yield of apricot trees using GPIT technology is 7 times of that of the control trees, and the benefit is 14 times of that of the control trees At the beginning of 2000, hadatun, Wugang Town, Harbin used GPIT technology to plant greenhouse cucumbers, all of which were applied with farmyard manure The color of cucumbers was dark green, the taste was excellent, and the yield was nearly doubled The photosynthetic rate, vitamin and amino acid increased by 409%, 28.7% and 9.5% respectively - solved the century's problem of crop self resistance expression, high resistance to root, stem and leaf diseases, and opened up a new way for the development of ecological agriculture and green food In 1999, a 100 mu wheat continuous control experiment was carried out in Guandu District of Kunming City, in which pesticide was applied three times per mu of wheat without GPIT, and powdery mildew was still very serious; while in the 100 mu of wheat treated with GPIT, no pesticide was used, and almost no infected plants were found In 1999, rice blast was very serious in Hexi 35, Guandu District, Kunming Most rice fields only collected 200-300kg per mu, some even lost However, the whole village of Yangxi village in this area uses GPIT technology in a unified way, and no rice field is affected The average yield per mu reaches 700 kg In 1998, the Crop Genetics Laboratory of Yunnan Agricultural University carried out three kinds of tobacco disease resistance tests on "Honghuadajinyuan", a high-quality flue-cured tobacco None of the diseased plants was treated with GPIT technology, while the other two were infected with powdery mildew and catarrh FAO paid close attention to this technology and obtained information from Yunnan Institute of ecological agriculture The expert review group chaired by the township enterprise development center of the Ministry of agriculture of China in Beijing gave a very high appraisal to this technology The experts believed that GPIT technology has the function of enhancing the cold resistance and frost resistance of crops and improving the photosynthesis efficiency It is of great significance to enhance the resistance and yield of agricultural products in the high altitude and poverty-stricken mountainous areas of Southwest China and wheat and other crops in the north Cold disaster and drought disaster often occur in the north of China Seasonal drought and high degree of cold disaster are common in the south mountainous areas There are many rainy days and insufficient light in the southern dry rice seedling raising period This technology has a broad market prospect in the above areas This technology takes Yunnan wild plants as the main raw material, and through the multi-point crop test, it is conducive to the production of green agricultural products, with advanced technology China feed industry information network xee (author:)
