Heilongjiang agricultural reclamation region is one of the main commercial soybean production regions in our country, but soybean yield was low and unstable in the past years.Studies on the high-yield cultural practice and analysis of the fac tors of the low and unstable yield of soybean in this region based on environmental conditions, technical methods, and relationship between soybean growth and development had been carried onto sets of comprehensive farming technical methods were assembled depending on different cological conditions and climatic conditions. Limiting factors of yield were overcome, and natural resources and potential of technical methods of conprehensive cultural practice were well used. Through the experiments the optimum technique of high-yield of the definite soybean variety in each ecological region were chosen.Through large-scale three years tests in different climatic conditions and regions, yield reaches 350 to 400 jin per mu in the six middle-yield localities, the yield increase was 75.1 percent more than the average yield of the last three years. In the three low-yield lacalities yield reaches 250 jin per mu and is 2.27 times more than the average yield of the last three years.

黑龙江垦区是我国重要的商品大豆生产基地之一,但亩产长期处于低而不稳的状况。 大豆高产栽培开发研究,用系统观点,从环境条件、农艺措施和大豆生长发育的相互关联中,分析了大豆单产低而不稳的原因;用系统工程方法,依据各地生态特点,气象条件的变化,综合组装农艺措施,突破限制因素,有效地发挥了自然资源优势和技术措施的增产潜力;用回归设计方法,试验优化了各生态区主要品种的高产农艺组合。 通过三年在不同地区,不同气候条件下的大规模试验,使六个中产变高产基点亩产达到350—400斤,比前三年平均亩产提高75.1%;三个低产变中产基点亩产达到250斤左右,增产1.27倍。

Atmospheric circulation is a decisive factor causing temperature difference, drought or waterlogging in a large area, other words, it is a main factor affecting crop growth and yield.

Atmospheric circulation is a decisive factor causing temperature difference, drought or waterlogging in a large area, other words, it is a main factor affecting crop growth and yield. This paper describes the relationship between soybesn yield per unit aroa and the composite index of atmospheric circulation feature-the parameters of latitude stripe spectrum at 500 hpa in the North-East region and there is a good time lag correlation between crop yield and the parameters of latitude stripe spectrum of field monthly mean during early growth period of crops. The mechanism of the correlation is the self time lag correlation of atmospheric cricuiation and the organic connection of atmospheric circulation with the climate over a long period. An equation was established with the parameters related to latitude stripe spectraum,named IDW and it could be applied for soybean yield forecast in the North-East region because it fitted the past situations and could be extrapolated for soybean yield well.

大气环流是形成大范围地区旱涝和温度异常,影响农作物生长发育和产量波动的主要原因。本文探讨了东北地区大豆单产与描述大气环流特征的综合指标——500hPa纬带谱参数的关系。揭示了农作物生育前期500hPa月平均的纬带谱参数与农作物产量有很好的时滞相关,其相关机理是大气环流自身的时滞相关以及大气环流与长期天气过程的有机联系。用这些参数组建的I_Dw予报方程,其历史拟合和外推都比较稳定,可以用于产量予报。

This paper illustrated, oil Sanjiang plain,surface ploughing and deep digging could effectively improve the physical property of plough layer and subsoil, increase the total and rapidly available nutrients.resist waterlogging, prevent drought and promote the growth of soybean and could obviously increase the yield of soybean with the combination of other high yielding techniques.This provided a effective way for raising the unit yield level of soybean on loW-wet land of Sanjiang plain.
