Study On The Land Production Potential Of Wheat And Maize In The Grain Yield Project Area Of Hebei Province

In recent years,the primary task of China's agricultural science and technology work is to increase China's total grain production,and on the premise of increasing the total grain production to ensure China's food security,maintain China's social stability,ensure the health of our people,and ensure the national economic development.Nowadays,under the influence of the development of global economic integration,as the world's largest food importer,China's food security problem will have a significant impact on world food security.The purpose of this paper is to calculate the natural production potential of the land in the research area,tap the land production potential,divide the whole project area,and determine the key construction area of the project area,so as to make good preparation for further establishing a scientific land grading system.This paper takes wheat and corn as research objects in the grain yield engineering project counties of hebei province,takes the natural land conditions of hebei province as the background,synthesizes the natural factors of light,temperature,water and soil in each country,and USES the"mechanism method"to estimate the land production potential,thus drawing the following conclusions:(1)light and production potential:under the influence of solar radiation,the production potential of wheat and corn in the northeast of heilong port and the piedmont area of yanshan mountain is significantly higher than that in the piedmont plain area of taihang mountain.The photosynthetic production potential of wheat and corn in shenzhou country was the highest,respectively 78599kg/hm~2 and 82075kg/hm~2.The photosynthetic production potential of wheat and corn in nanhe country was the lowest,which were53406kg/hm~2 and 55768kg/hm~2,respectively.(2)production potential of light and temperature:the northeast of heilonggang and the foothills of yanshan are greatly affected by temperature,and the production potential of light and temperature of wheat and corn has a significant decline.But overall,the production potential of light and temperature of wheat and corn in the grain abundant project area of hebei province is higher.Guangping country has the highest light and temperature production potential of wheat and corn,which are 42555kg/hm~2 and44437kg/hm~2 respectively.The light and temperature production potentials of wheat and corn in shenze country were the lowest,respectively 28054.48kg/hm~2 and29295.21kg/hm~2.(3)climatic production potential:the climatic production potential of wheat and corn decreased obviously under the influence of rainfall,and the shortage of precipitation has seriously restricted the production of crops.The climatic production potential in the piedmont area of yanshan mountain is relatively higher than that in the northeast of heilong port and the piedmont plain of taihang mountain.Zunhua country has the highest climatic production potential of wheat and corn,14880kg/hm~2 and 15538kg/hm~2 respectively.The climatic production potential of wheat and corn in dingzhou was the lowest,4351kg/hm~2and 4544kg/hm~2 respectively.(4)land production potential:the land production potential in the piedmont area of yanshan mountain is relatively high on the whole.The land production potential of wheat and corn in wuqiao country,dongguang country,botou country,shenzhou city,anguo city,anxin country,luancheng country and lingshou country is higher than that of other project counties in piedmont plain and black dragon harbor plain.The land production potential of wheat and corn is the highest in fengrun country,which is 13923kg/hm~2 and 14539kg/hm~2respectively.The land production potential of wheat and corn in dingzhou is the lowest,which is 4028kg/hm~2 and 4270kg/hm~2 respectively.(5)evaluation of land production potential:in the piedmont area of yanshan mountain,wuqiao country,dongguang country,nanpi country,botou country,wuqiang country,shenzhou city and rongcheng country,in the piedmont plain of taihang mountain,anguo city,lingshou country,shahe city,wu'an city and handan country have high potential and deep space for exploration.Counties with low promotion potential are mainly distributed in the central piedmont plain and the southeast of the heilonggang plain.The evaluation of upgradable production potential divides the whole project into four regions:high yield and high uplift potential area,high yield and low uplift potential area,low yield and high uplift potential area and low yield and low uplift potential area.In the study area,the main producing counties of wheat and corn have high potential of land production and large room for yield increase.We should make good use of light,temperature and water resources,improve infrastructure facilities in various regions,and make farmland of high standard through certain degree of governance.
