Breeding is strengthening - whether there is a dominant breed
Breeding corn grain machine harvesting harvesting machinery to keep up with the pace
[China Agricultural Machinery Industry News] In the past few days, the on-site demonstrations and exhibitions around the corn grain machine have been featured. Huanghuaihai has made breakthroughs in the “double early double night†varieties selected for wheat and corn. Corn varieties with a grain water content of less than 25% have been highlighted.
Breeding the corn grain machine to harvest the harvester to keep up with the pace
The two-year northeast corn grain harvesting project has been excavating and developing grain varieties for corn harvesting in different major maize producing areas in the Northeast. Nowadays, "Dayu 919", "Xiangyu 998", "Huamei No.1", "Dika 516", "Jidong 705" and other varieties have become the promotion varieties of Jilin Province, and it is expected to become the northeast corn grain machine in the future. The leading varieties, "Jingnongke 228", "Dika 517", "Fengyu 139", "Yulong 9" and other more than 10 varieties are also explored in Heilongjiang, Liaoning and Inner Mongolia.
“From the perspective of 27 varieties planted in the core area of ​​Jilin Province and 20 demonstration sites, there are still some gaps between the requirements of some varieties and suitable traits, but it is gratifying that many varieties have shown good performance. Appropriate machine traits can be used to promote grain harvesting or promote under certain conditions.†Zheng Qing, director of the Jilin Provincial Seed Management Station, said after analyzing the data, “From the perspective of multi-point harvesting, agricultural machinery and agronomy Mutual matching can reduce the difficulty of grain harvesting. Higher agricultural performance can partially compensate for the lack of variety agronomy; varieties with better agronomic performance have higher tolerance for agricultural machinery performance. The test models improve some parameters. It is closer to the needs of the northeast region, for example, the line spacing should be more flexible to adapt to the diverse planting patterns in Jilin Province, and the agricultural machinery should have higher adaptability. In addition, the corn in Jilin Province is generally high in stalks, and the power of harvesting machinery is strong. Improve machine efficiency."
Throughout the northeastern four provinces, the grain variety of corn harvested, there are not many varieties, mainly concentrated in the very early maturity area, the middle and early maturity, middle and late maturity and other areas still lack the shaped directional grain machine to harvest corn varieties. “At present, the variety of grain harvesting in the Northeast is mainly 'Demeia No.1'.†Chen Xuejun, director of the Jilin Province New Variety Breeding Center, said, “The other varieties are mostly in the exploration and demonstration stage.â€
With a good variety - harvesting machinery and not keeping up with
Planting a grain machine to harvest corn varieties can increase the efficiency of the growers, while buying corn grain direct harvesting machinery? The Northeast Corn Grain Harvesting Project analyzes the costs and benefits of purchasing corn grain direct harvesting machinery from Heilongjiang Wudalianchi Farm and Shuangcheng Dongguan Agricultural Cooperative. "For example, the Case 6088 corn grain direct harvester with a value of 1.8 million yuan is calculated according to the operation season of 30 days per year. The daily working area is 50 hectares, the cost per hectare is 1,000 yuan, the operation cost is 105 yuan, and the annual benefit is 450,000 yuan. The service life of the machine is 10 years, and it takes 4 years to recover the cost. In the 6 years after the recycling, it can earn a net profit of 2.7 million.†Chen Xuejun analyzed, “Whether it is a domestic model or an imported model, the cost recovery period is In about 4 years."
According to data from the National Bureau of Statistics in 2014 and 2015, the corn planting area in the four northeastern provinces exceeds 40% of the country. “Northeast corn planting area is about 220 million mu, of which the suitable machine harvest area is about 120 million mu, which is about 61.5% of the total corn planting area. In these areas, the grain harvesting area is only 33,500 mu, which only accounts for all The 0.1% of the machine-receiving area can be said to be basically blank.†Chen Xuejun said, “Even if you count 8 million mu of Heilongjiang Reclamation Area and 238,000 mu of Inner Mongolia Reclamation Area, it is only 3.6%.â€
According to the survey of the Agricultural Machinery Bureau (station) in the four northeastern provinces, the number of grain harvesting machinery in the four northeastern provinces is 2,826, including 593 imported machinery, which is far from satisfying the large-scale promotion of grain harvesting. demand. A John Deere S660 with a rated power of 320 hp is calculated on the basis of 50 hectares of harvest per day and 30 days of harvest per year. The corn kernel machine is 140 million mu, which requires 6222 units. The rated power of 160 hp Dongfeng E518 is 24888. station. From this point of view, the development of grain machine harvesting corn supporting agricultural machinery can be seen as the "blue sea" derived from the innovation of corn varieties. When selecting corn varieties suitable for grain harvesting in Northeast China, we must continue to strengthen the screening of supporting machinery. The agricultural machinery professional cooperatives are also indispensable as the grassroots carrier of agricultural machinery, and the orderly development of specialized service organizations is crucial.
