As a chip for agriculture, fine seeds contribute 45% to increasing grain production. General Secretary Xi Jinping pointed out that it is necessary to make up our minds to develop the national seed industry, pay close attention to cultivating excellent varieties with independent intellectual property rights, and ensure national food security from the source. Heilongjiang comprehensively promotes the innovation of the seed industry and strives to firmly hold the Chinese rice bowl in the hands of Chinese.
"The same kind of farming, you hit more than 9 tons in one place, I hit more than 11 tons, how much more do you have to sell?"
Speaking of farming, Liu Yunsheng, a farmer in the prosperous village of Lifeng Township in Huachuan County, has a proud face. To ask Lao Liu's harvest secret, we have to start with the seed. At the beginning of the year, the Rice Research Institute of heilongjiang academy of agricultural sciences cultivated a new variety of rice, dragon japonica 3013, and Lao Liu, who has always loved to challenge, became the first person to eat crabs, with a yield of more than 750 kilograms per mu. Pan Guojun, a second-level researcher at the Rice Research Institute of heilongjiang Academy of Agricultural Sciences, said: Long japonica 3013 is likely to replace Long japonica 31, which currently has the largest production area in the future.
Ten years ago, the rice varieties in the third and fourth temperate zones of Heilongjiang Province were almost all foreign seeds, and it was "Dragon Japonica 31" that drove out the "foreign seeds". How do we grow our own seeds? This issue has been inspiring Chinese rice researchers. Selecting a species is like finding a needle in a haystack, and it is even more difficult to breed a good variety. After countless failures, "Dragon Japonica 31" finally broke through the ground, under the same climatic conditions, stronger than the rice seedlings grown by "foreign seeds" and resistant to plague.
If the seeds are firmly in the hands of Chinese, the Chinese rice bowl is in China's hands. With the start of the seed industry turnaround battle, more and more "Pan Guojun" have joined the "seed" cultivation army. This year, the new soybean variety Longken of beidahuangfeng Seed Industry produced more than 300 kilograms of 3,092 mu, setting a new high for the fourth temperate soybean variety in Heilongjiang Province. Usually it takes 10 to 12 years for fine seed breeding, but Hu Xiping, president of the Soybean Research Institute of Beidahuangkenfeng Seed Industry Co., Ltd., only took 7 years. Kenfeng Seed Industry ranked second in the country in seed sales revenue in 2020, with an average annual R&D investment of more than 80 million yuan in the past 5 years.
This year, Heilongjiang breeding success is frequently reported, Long japonica 3010 and Long japonica 3013 have reached the northeast early maturing japonica super rice yield index; the five soybean experimental varieties cultivated by the Northern Soybean Research Institute of Suihua City and the high-protein soybean varieties of the Provincial Academy of Agricultural Sciences have exceeded 520 jin per mu, exceeding the national average. The new corn varieties of the Jiamusi Branch of the Provincial Academy of Agricultural Sciences yielded 875 kilograms per mu, which was more than double the average yield of domestic corn per mu. At present, the main crops in the province have basically achieved full coverage of fine seeds.
