三垄栽培是旱作大豆综合高产栽培技术,已在黑龙江垦区推广。我场通过4年实践,认为在具体实施过程中,应特别注意以下技术的配套使用。一、计划秋起垄种大豆的麦茬地,应先深松耙茬或旋耕我场部分生产队,为了配合三垄栽培的秋起垄作业,在麦茬地先行深松耙茬或旋耕,均收到了良好效果。据调查,1987年,深松耙茬后起垄比平翻起垄亩增产20.8千克;1988年,深松耙茬,旋耕后起垄,比平翻后起垄亩增产分别为25.5千克和20.5千克。由此可见,计划秋起垄种大豆的麦茬地,应积极推广深松耙茬或旋耕。
Sanyu cultivation is a comprehensive high-yield cultivation of soybean cultivation technology has been in Heilongjiang reclamation area promotion. My field through 4 years of practice, that in the specific implementation process, special attention should be paid to the use of the following technologies. First, plan the autumn stubble soybeans stubble stubble, it should be deep loose stubble or rotary farm some of my field production team, in order to meet the three ridge cultivation of autumn ridge operations, the first in the stubble stubble stubble or rotary tillage, Have received good results. According to the survey, in 1987, after deep-seeding stubble, the ridge ridge increased by 20.8 kg. In 1988, the deep-seeding stubble and rotary furrow ridge increased 25.5 kg compared with that after flat-ridged ridge. 20.5 kg. Thus, the planned autumn stubble soybeans stubble, should actively promote deep-stubble stubble or rotary tillage.
