The top drought-resistant corn varieties were introduced, saving water and fertilizer 50
Preface. Drought-resistant varieties have always been the focus of agricultural scientists. China faces the challenge of vast arid and semi-arid regions, and the search for water-saving and efficient drought-resistant maize varieties can reduce the planting pressure of farmers in arid areas and increase food production. In this context, after years of research and experiments, Shanxi Institute of Dryland Agricultural Science and Technology has successfully cultivated a new drought-resistant maize variety, Hongyu No. 7.
Features and experimental results of Hongyu-7.
Hongyu No. 7 is a corn variety that has been scientifically bred and experimentally observed, saving more than 50% water and yielding better than other varieties. Its unique drought-resistant properties make it the best choice for water-saving cultivation, guaranteeing high yields and reducing dependence on water resources.
In the experiment, Hongyu 7 was compared with the control variety ZD958, which used the traditional ratio of nitrogen, phosphorus and potassium, while Hongyu 7 used controlled-release fertilizer, and the experiment proved that the fertilizer saving effect of Hongyu 7 reached more than 50%. In addition, Hongyu 7 has better drought tolerance and disease resistance than ZD958, showing stronger adaptability to arid environments.
At the time of harvest, Hongyu 7 yielded 1596 kg mu, while ZD958 produced 1408 kg mu. This result was a pleasant surprise and proved that Ruby 7 can maintain high yields while saving water and fertilizer. In addition,"Ruby No. 7"None of them were infected with rust in the two-year test, and they had good green retention, which provided a guarantee for continuous photosynthesis.
Analyze the advantages of Hongyu 7
1) Well-developed root system: The root system of Hongyu No. 7 is more than 21% longer than that of the control variety, and the lateral roots are developed and more favorable, which can better absorb water and fertilizer in the deep and surface layers, and improve drought resistance.
2.Good disease resistance: Hongyu No. 7 has strong resistance to southern rust, good green retention in the later stage, uninterrupted photosynthesis, and can continue to produce brittle seeds, thereby increasing yield.
3) Save fertilizer and water:"Ruby No. 7"With controlled-release fertilizer, the amount of fertilizer applied is halved, and more than 50% of fertilizer can be saved through precise fertilization technology. At the same time, under normal irrigation conditions,"Ruby No. 7"There is no need for watering, further reducing the need for water.
4) Trademark Certification:"Ruby No. 7"Trademarks with"Twin provinces"At the same time, the trademark was approved by the State Intellectual Property Office, which provides a better guarantee for the promotion and application of the variety.
Personal reflections and conclusions.
Cultivating drought-resistant maize varieties is of great significance to China. Large areas of land in arid and semi-arid regions are irrigated and water resources are limited, so it is important to find a drought-resistant maize variety that can guarantee high yields under water-saving conditions. The breeding of Hongyu 7 has successfully filled the gap of drought-resistant maize varieties in China, and has good market prospects and economic benefits.
However, the development of drought-tolerant varieties still faces many challenges. In addition to drought resistance, many factors such as disease resistance and market adaptability need to be considered to meet the planting needs of farmers in different regions and with different needs. At the same time, the key to further promoting the development of drought-resistant agriculture is to strengthen the demonstration, popularization, and training of drought-resistant varieties and to improve the awareness and use level of farmers.
In the future research and development process, I hope to see further progress and application of drought-resistant corn varieties. Through continuous investment in scientific research and experimental verification, we will continue to improve and optimize the performance of drought-resistant varieties, achieve true green agricultural development, and make greater contributions to China's food security and sustainable agricultural development.
