播种施肥装置采用单体形式，地轮配置在播幅之内机架后方，能保证播种到地边；采用刀式破茬开沟器，入土阻力小，能在带麦茬未耕土壤里进行同位深施肥和播种作业。

The authors emphasize the importance of market prediction and suggest the establishment of a professional institution for market research. The adjustment of product mix must be considered in a macroview to avoid the dilemma of small scale, multi - varieties and low economic benefit. Not to abondon a certain variety: single superphosphate plays an important role and nitrophosphate takes an unique advantage in its process. Careful support is needed to the new nitrophosphate facility in an old enterprise. Triple superphosphate is a good product where its market launching and further processing are to be enhanced.

指出做好需求预测工作的重要性，建议建立我国化肥需求预测研究的专门机构；产品结构的调整应从宏观角度考虑，避免重新陷入小而全、低效益的国境；对磷复肥品种不宜轻易否定某一品种，低浓度磷肥过磷酸钙仍将发挥很大作用，硝酸磷肥有它工艺上独特的优点，支持老企业新建硝酸磷肥装置应慎重、重过磷酸钙是高浓度水溶性磷肥，是个好品种，应加强市场开拓，尤其是二次加工的研究开发工作。
