Corn planting has always been an important planting variety in China's agriculture. With the development of agricultural science and technology and modernization, corn planting has undergone new changes. Based on this status quo, the article mainly analyzes the changes in corn planting methods, which is convenient for corn farmers to better grow corn.
1. Analysis of current status of corn planting
Maize is an important food crop and can be used as a feed for livestock farming. Its worldwide total production is the first in food crops. With the continuous development of modern agriculture, the problems in the traditional corn planting methods are gradually exposed, and some improved corn planting methods have emerged correspondingly, creating a good foundation for increasing corn production and increasing income. Therefore, it is of great practical significance to analyze the changes in corn planting methods. The article mainly analyzes the current corn planting methods.
1.1 Isometric cultivation
According to the actual production activities, most of the farmers are planting corn every spring. The planting spacing is relatively loose. Usually, 2~3 seeds are sprinkled in the excavated foundation pit, and the seeds are germinated and budded. After the seedlings exceed 2 cm, the sprouts with poor growth are removed and the most prolific sprouts are retained. Some scholars have proposed the concept of “directional plantingâ€, which means more rational use of planting land, scientific planning of planting density, and full use of lighting conditions to ensure the healthy growth of corn. The fact that this theory is not used in actual planting is mainly a problem of its own, mainly focusing on poor control of planting density, ventilation and light transmission.
1.2 Double plant cultivation
The cultivation of double plants is widely used in the northwest region, and has the advantage of reducing the rate of empty rods, which can increase the yield of corn. The application of this planting method in actual planting can effectively solve the lodging problem common in the planting process, and is suitable for large-scale corn planting, but the disadvantages of this planting method are also obvious, that is, the labor volume is large, and the management Difficulties and other issues.
1.3 wide and narrow row cultivation
The compact corn planting method is a new type of corn planting method. Based on the sunlight and foliar index required to ensure corn, the planting method can increase the planting density of corn by wide and narrow planting methods. Effectively solve the problem of ventilation and light transmission, but this method can not guarantee the nutrient and water demand during the growth of corn, which may affect the yield of corn.
2. Development trend of corn planting methods
2.1 Optimize planting methods
With the continuous advancement of modern science and technology, the method of crop planting has undergone major changes. However, most of the current planting methods have certain problems, and there is no completely ideal planting method. Therefore, the reform and optimization of planting methods are continuously carried out. Important practical significance. At present, the two-row staggered planting method is often used in developed countries. The method refers to changing the row that should be planted into two rows with a row spacing of 2.5 cm in actual planting, and then assigning the original number of plants to other rows when planting the seedlings, and then actually planting according to each row. Quantity, forming a staggered layout. The advantage of this planting method is that it can increase the number of planted plants, and at the same time increase the spacing between plants, ensure sufficient nutrients during plant growth, increase the absorption rate of fertilizers, and finally achieve the effect of increasing production and income. However, when applying this method, the place to pay attention to is: pre-treatment before formal planting, mainly through the form of ploughing, the effect of ploughing can be guaranteed if the ploughing is deep-turned; On the basis of the local planting environment, choose a variety with high nutrient content and good taste. Guided by consumer preferences, choose the corn variety that people like. In addition, in the transplanting work, a moderately sized hole can be cut on the mulch, and then the transplanted seedlings can be placed in a layer of fine mud to effectively prevent pests and diseases.
2.2 Improve management level
The planting and management of corn is constantly developing scientifically, especially the continuous development of agricultural planting techniques, which has led to the continuous improvement of the level of mechanization of planting, and the corresponding changes in the level of planting management. With the continuous development of China's urbanization level, young people in rural areas have gone to cities to seek opportunities for development, which has led to a significant reduction in rural labor, thus transforming the traditional planting mode and using mechanical equipment to improve planting efficiency. In the corn planting management, it is necessary to make appropriate adjustments, pay attention to ecological benefits, and pay attention to market demand. At the same time, combined with factors such as planting conditions and development level, the camp is committed to providing production technology guidance services for corn growers through integrated production technology. At the same time, strengthen the formation of the industrial chain, thereby developing the corn production base, continuously reducing production costs, and improving the planting efficiency of farmers. The management of corn has an important impact on its ability to maintain good growth and economic benefits over the long term. The maintenance and management of corn is a long-term work. Therefore, it is necessary to pay attention to the daily assessment of corn management, and pay attention to the inspection of corn management technology to ensure the orderly development of corn management. In addition, it is necessary to strengthen the professional training of growers and improve planting capacity, thereby improving the efficiency of corn management.
2.3 Improvement of mechanization level
With the continuous improvement of modern industrial level, mechanization, informationization and systemization are the main development trends of agriculture. Maize cultivation and management are also constantly developing towards mechanization. In recent years, more and more advanced machinery has been applied to agricultural production. In addition, not only the management efficiency is improved, but also the output and quality are improved. However, the application of the machine needs to be combined with the actual situation and cannot be blindly quoted. Otherwise, the machine may be scrapped, resulting in an increase in cost.
2.4 Improvement of planting level
At present, the problem of low professional level is widespread among growers, resulting in low efficiency and quality of corn planting, which cannot effectively guarantee the orderly development of corn planting work. Therefore, in order to improve the level of corn planting, it is necessary to improve the professional level of the growers through effective professional training and continuing education, so as to ensure the efficiency and quality of corn planting work. When selecting seeds, it is necessary to use the variety and adaptability as the assessment criteria, and do the appropriate selection work to improve the professional level of the growers, and continuously transmit new planting concepts, strengthen their own learning, and help improve corn planting work. s efficiency. In addition, there is a need to strengthen the management of corn cultivation to ensure the achievement of the goal of increasing production and income. In the process of planting, it is necessary to strengthen the management of corn, thereby promoting the development of corn planting and increasing the income of growers.
In order to improve the economic benefits of corn planting, planters need to have a deep understanding of corn planting techniques and follow-up management. Therefore, it is necessary to strengthen the reform and follow-up management of planting techniques to promote the economic benefits of corn planting.
The above is the analysis of the new changes in corn planting and the development trend of planting in the small series compiled by Huinong. I hope this article can bring you new corn planting thinking. Finally, I wish you a good harvest for corn growers!
