黑龙江垦区施肥机械概况及发展方向

施肥方法对作物增产效果有显著影响,根据目前垦区施肥机械的使用和研究情况表明,垦区施肥机械的发展方向,除用好已有的耕播机外,应研究改变现行耕作制,用旋耕深松深施肥机代替铧式犁翻地,以扩大秋深施肥的面积,同时研制小麦芽期深追肥的机具,以解决因不能秋深施肥所造成的小麦后期脱肥而减产。

THE SURVEY AND THE DEVELOPMENT DIRECTION OF FERTILIZER APPLICATION EQUIPMENT IN ST.TE FARMS OF HEILONS JIANG PROVINCE

The incroment of yield is greatly affected by application methods of fertilizers. According to present studies, the development direction of fertilizer application equipment for state farms has been indicated. Besides using the new models on hand, it is neccessary to change the tillage system, to substitute moldboard plow for rotary-deep tillage and deep-fertilizer-applieating units to till the land, which increases the effective area of deep-placed fertilizer in fall. Meanwhile, conduct research to develop new application units for fertilizer applieations. while wheat seeds are germinating, to compensate the yield losses caused by insufficient fertilizers at the later growing stage due to the lack of deep fertilizing in fall.
