Practice And Discussion On High Yield Of Maize In Baoji City

In recent years, with the rapid development of urbanization in our country, the area of cultivated land is decreasing year by year. At the same time, with the restriction of the natural environment resources, the rigid growth of the total population of the country, the demand for grain crops increased year by year. In order to ensure the effective supply of food, to ensure the security of our country, the realistic choice is to rely on science and technology, increase crop yield, to ensure that the total grain yield. Implementation of the project to create a high grain yield is an effective measure to improve the sustainable development of grain production, enhance the comprehensive production capacity and ensure the absolute safety of food rations.Beginning in 2009, Baoji began to implement the project of corn production. By the end of 2015, from the original two counties to 8 counties to achieve full coverage of the city's main maize producing counties. 7 years, a total of 86 thousand and 800 hectares of land to build a model of hectares, a total increase of 207 million 140 thousand kg corn, the total value of 435 million 649 thousand and 100 yuan. Compared with the average yield of three years before the implementation of the project area, summer maize high yield per 666.7m2 yield 140.68 kg, high yield of spring maize yield per 666.7m2 create 232.52 kg, the city's corn high yield average revenue per 666.7m2 increase of 334.73 yuan, the implementation of benefit is very obvious. The implementation of the project to create a high yield of corn, driven by the level of corn per unit yield in Baoji city. The city's corn yield by 2009 4965kg/km2, increased to 2015 of 5175kg/km2, an increase of 4.23%. Demonstration leading role of the project, to achieve a balanced production of corn in Baoji city.In view of the existing Baoji corn production varieties and miscellaneous, main varieties yield potential of maize planting rice is not high, low density, degree of mechanization harvest, high cost problems in the implementation of production, high yield of Maize to create the project, promote the introduction of the Shaandan 609, Yu Dan No. 9 and Zhengdan 958 Jundan 20, a number of new varieties of compact corn. On the basis of experiment and demonstration on the assembly support the extension of high yield and high efficiency cultivation technology, through the promotion of rational close planting, timely control, fertilization, irrigation, scientific and timely late harvest integrated technology, the formation of the spring and summer maize high-yield technology rules. Implementation of the project, the city's corn density than before the implementation of the increase in 7500-15000 strain /km2. Corn harvest time in the case does not affect the sowing of wheat, to achieve the appropriate late harvest, the general harvest time around October 5th. Through the implementation of the project, the city's new corn varieties to promote the cultivation of a large area, to speed up the pace of maize varieties.In the implementation of the project, through the implementation of subsidies, subsidies from seeds, fertilizer, plastic film, pesticides and other production to tractor Mechanized Sowing and harvesting and other sectors, to reduce production costs improve the masses, planting benefit. Through the establishment of a typical model of high yield, demonstration to guide the production of large areas, there have been a number of typical corn yield. At the same time, actively explore new ways of scale management in the project area, relying on the project area of new business entities, the concentration of land, stock cooperative, managed their scale of production, the appropriate scale of operation, to improve the quality and level of grain production. In the project area, and actively guide the new business entities, agricultural cooperative organizations, as organizations, food processing enterprises, providing social services, agricultural machinery farm supply, irrigation and pest control of the whole or individual sectors for high yield, improve the new technology should be used in place rate and rate. In the implementation of the project, and constantly improve the creation of performance evaluation mechanism, and fully mobilize the enthusiasm of all aspects of the formation of a joint force, to ensure that the high yield to create activities carried out in depth.Aiming at the key technology demonstration area to create unbalanced regional development, coverage needs to be improved, the mechanism and system is not perfect, with agricultural agricultural problems closely enough, new subject cultivation work still needs to speed up project implementation, put forward the development strategy. Through the establishment of a new development ideas to create new ideas, to create a new concept, highlighting the number, quality and effectiveness of both, take the green development path of weight loss. Strengthen promotion departments, research institutes and relevant agriculture related departments such as multi link, collaborative technology, realize the close combination of research and extension. Strengthen and improve the promotion system, focusing on strengthening the construction of the town village network, to carry out technical personnel training, improve the quality of Personnel Science and technology. Promotion of integrated and simple technology, the introduction of new breakthrough varieties, the promotion of integrated technology. To further promote the integration of agricultural machinery and agriculture, focusing on the training of agricultural machinery. Actively cultivate new business entities, to promote the development of norms and other measures to promote the production of corn in Baoji to create a better work.
