我队地处关中北部黄土高原,年雨量600毫米,多集中在夏秋两季,气候干燥。在无产阶级文化大革命推动下,我们实行科学种田,采用“抓全苗、育壮苗、促春发”的技术措施,使近几年来680亩油莱亩产达到200斤以上。1974年又获得亩产237斤的好收成。下面谈谈我们是怎样育壮苗、促春发的: 提早管理,培育壮苗 (一)施磷肥作种肥随条播机或耧顺沟溜施磷肥,对促进根系发育、培育壮苗,增强抗逆能力,增加产量有显著作用。据试验,亩施20斤过磷酸钙可增产13-44％以上,每斤过磷酸钙增产油菜籽2-6.2斤,薄地增施磷肥效果更为显著。多年来,我们每亩施用30斤过磷酸钙。随着氮素肥料和产量水平的提高,现在又增加到50斤左右,并采取分层施入。
My team is located in Guanzhong northern Loess Plateau, the annual rainfall 600 mm, mostly concentrated in summer and autumn, the climate is dry. Under the impetus of the Great Proletarian Cultural Revolution, we have adopted a scientific approach to farming and adopted the technical measures of “grasping whole seedlings, nurturing strong seedlings and promoting spring development” so that the yield per mu of 680 mu of oil ramies will reach over 200 kilos in recent years. In 1974 and received a good harvest of 237 pounds per mu. Here to talk about how we grow strong seedlings, promoting spring hair: early management, nurturing strong seedlings (A) of phosphate fertilizer as seed fertilizer with seed drill or shun Shun furrow phosphate fertilizer, to promote root development, nurturing strong seedlings, enhanced Reversal ability, increase yield have a significant role. According to the test, Mushu 20 kg superphosphate can increase 13-44% more, per kg of superphosphate increase rapeseed 2-6.2 kg, the effect of phosphate fertilizer application is more significant. Over the years, we applied 30 pounds per acre superphosphate. With the increase of nitrogenous fertilizer and output level, it is now increased to about 50 kg and taken into layers.
