京山县宋河区,是一个以一季中稻为主的地区。年平均温度13℃左右,年降雨量约1,000毫米,但分布极不均匀,在水稻需水量最多的7月,一般降雨量100毫米左右,而在播种育秧阶段的4月,又是寒潮频繁、阴雨较多的日子。由于劳畜力较缺乏,耕作较粗放,水稻单产一向较低。1964年进行了一系列栽培技术的改革,虽在水稻生长期中受到了长达40天(6月24日到8月3日)干旱的影响,但比收成较好的1963年增产23.6%。现在把这里推广科学研究成果,进行技术改革的主要经验总结如下。
Jingshan County Songhe District, is a season of rice-based regions. Annual average temperature of about 13 ℃, the annual rainfall of about 1,000 mm, but the distribution is extremely uneven, in paddy water demand in July, the general rainfall of about 100 mm, while in the sowing stage of seedlings in April, is cold, More rainy days. Due to the shortage of labor and livestock resources, extensive farming, rice yields have always been lower. A series of cultivation techniques were carried out in 1964. Although it was affected by the droughts of 40 days (June 24 to August 3) during the rice growing season, it was 23.6% more than that of 1963, which had a good harvest. Here is a summary of the main experience of promoting scientific research and technical innovations here.
