Description
Technical field
The invention belongs to the Agricultural Information technical field, be specifically related to management area quantity of cultivated land, farmland production and soil nutrient status on visual map, instruct for peasant household provides the fertilising of science.
Background technology
At present Chinese people ground is particularly thorny, according to the numeral of the Ministry of Agriculture with Ministry of Land and Resources's announcement, from 1996 to 2004 8 in the period of, China's cultivated area reduces to 18.37 hundred million mu from 19.51 hundred million mu; 2005 reduce 5,400,000 mu; 2006 reduce 1,000 ten thousand mu.China has 1,300,000,000 populations at present, wherein 9.4 hundred million is agricultural population, about 2.5 hundred million peasant household units, cultivated area has only more than 7 mu per family, and national per capita area of cultivated farmland has only more than 1.4 mu, only is equivalent to 40% of world average level, farther average level far below American-European countries, therefore, the child care in arable land, the quality of increasing soil fertility is for guaranteeing that national food safety is most important.
Northeast black soil region especially song-Nen plain haplic phaeozem district is done for the problem of food and clothing that solves national food safety and tens00000000 populations and is appeared special contribution.But because people ground is particularly thorny, in order to improve grain yield on limited soil, the major part that the farmland is adopted is that light mode of supporting is managed and heavily planted to the predation formula for a long time, has therefore caused farmland quality to descend, the soil is planted thinner and thinner, and the natural production ability reduces.Data shows according to the study, black earth is opened up wasteland soil organic substance content decline 30-40% after 20 years, open up wasteland organic substance decline 50-60% after 40 years, meanwhile, the reserves of plant nutrient nitrogen and phosphorus also descend simultaneously 30-60% and 16-24%, in this case, the peasant has to keep higher grain yield by dropping into a large amount of chemical fertilizer, and the fund input of chemical fertilizer has accounted for whole production and dropped into more than 50%.
The nineties in last century, China's chemical fertilizer purity nitrogen consumption accounts for 21.6% of the total consumption in the world.China ploughs and on average uses the fertilizer nitrogen amount is 224.8kghm
-2, wherein have the average amount of application of 17 provinces to surpass internationally recognized upper limit 225kghm
-2National fertilizer amount was 4,766 ten thousand tons in 2005, and 2006 is 4,927 ten thousand tons, and 2007 is 5,108 ten thousand tons, whenever applies 0.5 kilogram of chemical fertilizer and only gains 4.9 kilograms of grains, and national fertilizer amount is annual to increase nearly 2,000,000 tons.China has become the maximum country of chemical fertilizer use amount in the world at present, chemical fertilizer has played enormous function in the grain high yield, but because the agricultural pollution that the chemical fertilizer improper use has caused is serious, the moderate of underground water, rivers and lakes and serious pollution, the ammonia concentration of rural area atmosphere is obviously higher, the discharge capacity of greenhouse gases nitrous oxide estimates to have accounted for the about 30% of world's total release, and farmland quality is degenerated and environmental pollution has reached surprising degree, is subjected to international concern.According to statistics, the annual farmland of China enters in soil and the water environment more than 1,000 ten thousand tons with nitrogenous fertilizer is nearly, and many agricultural product nitrate nitrogen contents are obviously exceeded standard.
The existence of these problems shows that problem of management is quite serious in process of crop growth.The undue input of chemical fertilizer and drop into does not unbalancedly have codes and standards.Such as in same zone, under the little situation of same crop and soil basic condition difference, the amount of application of different peasant households chemical fertilizer may differ 10 times.And organic manure application rate reduces year by year, and farmland quality descends obviously.The farming control measures that the peasant of contract cultivate land does not have a cover land used to increase soil fertility make the farming management be in state arbitrarily for a long time, thereby have limited the performance of crop yield.
