东北垦区国营农场种植小麦的面积约占粮、豆播种面积的45—50%左右。种小麦不仅机械化程度高,而且稳产保收。一般年成可获得亩产150—200斤以上的产量。在气候条件有利时产量更高,如1964年友谊农场五分场五队的春小麦平均亩产348斤。五九七农场三队一号的92垧地(每垧为15亩)平均亩产486.7斤,其中56垧平均亩产达到533.3斤。但目前各场生产极不平衡,如何挖掘潜力,找出增产关键,争取进一步高产稳产和均衡增产是当前农业技术急待解决的问题。 The area planted by the state farms in the northeast reclamation area accounts for about 45-50% of the sown area of ​​grain and beans. Wheat is not only highly mechanized, but also stable yield. As a general annual yield can be obtained over 150-200 kg per mu. Yields are higher when climate conditions are favorable. For example, the average yield per mu of spring wheat in the five teams at the Friendship Farm five-field stadium in 1964 was 348 pounds. The average output per mu of 486.7 jin (92 mu land per parcel of 15 mu) at No. 1 March 3 Farm One was 533.3 jin, an average of 566 mu. However, at present, the production of various fields is extremely unbalanced. Therefore, it is an urgent issue that agricultural technologies urgently need to solve the problem of how to tap the potential, find out the key to increasing production, and strive for further high and stable production and balanced production.
