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。

This paper deals mainly with the contents of trace elements in soils of Haitian Land Reclamation region at the present state.The contents of Ca,Mg and Cu.Mn.Zn.Mo,B etc in diverse Soil types.Parent materials and the dis- tribution of these elements in the horizon of soils are compared with.Moreover, the relationship between the avalable quantity and total quantity of several trace elements and the soil organic matter content are discussed. The results of survey show that the content of Ca in soils is tow low;Some Sandy Soils are deficient in Mg;However,the contents of Cu,Mn,are compar- atively abundant,but some parts of soils are deficient in Zn,Mo and most parts of the soils are deficient in B,especially in paddy fields.

本文着重介绍海南农垦地区土壤的微量元素现状。比较了不同土类、不同母质土壤的 Ca、Mg 以及 Cu、Zn、Mn、Mo、B 的含量水平,及其在不同类型土壤土层中的分布,并分析了几种微量元素的有效量与全量及有机质的关系。调查结果表明:海南垦区土壤 Ca 含量都很低;某些砂性土缺 Mg;Cu、Mn 皆较丰富,部分土壤缺Zn 和 Mo,而大部分土壤缺 B,水田缺 B 尤为普遍。

The desertification area in stePPe-reclamation region in the northern Part of Shangdu County has reached 1069000 mu,among which the developing desertification area is 926650 mu,the intensive developing area, 82350 mu,and the grave desartified area,60000 mu.

本文以商都县北部为例,对草原农垦区风蚀、沙漠化的现状,发生、发展及其特征进行了初步探讨,提出了该区土地风蚀、沙漠化的主要因素是在干旱多风的自然条件下,过度开垦沙质草原导致强烈风蚀所致。并认为该区现代沙漠化的发生时间为60—70年,沙漠化的发展则在近20—30年,并且以较大面积的风蚀地(风蚀残丘、风蚀洼地)、粗化地表、灌丛沙堆和片状流沙为主要地表特征。 本文提出乌盟后山草原农垦区沙漠化的整治应该是:调整土地利用结构,控制农垦,固定基本农田,退耕风蚀、沙漠化耕地,还林还牧;以农田防护林网为骨架,进行区域性控制,以片林堵风阻沙,提供生物防护;以草定畜,防止草原过牧;种树种草,增加植被,固定地表,进行综合性治理。
