遵照毛主席关于“有比较,才能鉴别”的教导,为了提高二晚趸秧的产量,我们进行了二晚趸秧播种期试验。一、试验的基本情况供试品种为新选二号,武农早、嘉农14、农垦58。均于6月19日、6月26日、7月3日,分三期播种。种子用2%甲醛闷种4小对,摧芽播种,播种量每亩600斤。趸秧苗床为水田,于6月12日开沟作厢,厢宽5尺,厢沟1尺,排出厢面水,保留沟水,使厢面湿润,让杂草发芽,然后自然落干,使厢面晒硬(即部分发裂)。播种前一天,厢面灌跑马水润泥,厢沟中灌深水,使沟泥融活。播种当天下午6时左右,将厢面杂草除尽,厢沟中泥巴和烂,均匀铺在厢面,泥厚一寸,浇水(?)平,随即播种,播后塌谷,复盖麦 Following Chairman Mao’s teachings on “comparison, ability to differentiate”, we conducted two nights of seedling sowing trials in order to increase the yield of two-seedlings. First, the basic situation of the test Varieties tested for the new election on the 2nd, Wu agricultural early, Jiaonong 14, Nongken 58. All were sown on June 19, June 26 and July 3 in three phases. Seed with 2% formaldehyde stuffy 4 pairs, destroy bud sowing, planting 600 acres per acre. The seedling seedbed is a paddy field and is ditched into a box on June 12, with a width of 5 feet and a width of 1 foot. The water is discharged from the surface of the box and the ditch water is kept to make the box face wet and the weeds germinate and then fall dry naturally. Make the car tan (ie, partially cracked). The day before sowing, car surface watering horse mud, filling the deep water in the ditch, so that ditch mud melt. Sowing day around 6 pm, the car weeds will be removed, the ditch in the mud and bad, even shop in the car, mud thickness, watering (?) Flat, sowing immediately after sowing after sowing, covered with wheat
