我们自1973年开展春小麦丰产栽培试验工作以来,在各级党委的正确领导下,经历了各种自然灾害的考验,获得了较好成绩。亩产由1972年的474斤提高到1976年的715斤,增长59.3％。近五年来,高产田块都稳定在900斤以上的水平。1976年,战胜了苗期低温、霜冻及收获期阴雨等自然灾害,百亩丰产方平均亩产超过八百斤,其中,最高的一块1.47亩,亩产962.8斤。今年在4月下旬严重低温、寡日照及5月下旬花粉母细胞减数分裂期的低温情况下,仍有50亩过江和小面积超过900斤田块出现。通过五年试验,现将春小麦丰产栽培中几项技术措施分析如下。 (编者按:本刊77年1期已刊载《春小麦丰产栽培中几项关键技术措施的探讨》一文,可与本文参照阅读。)
Since we started the experiment of spring wheat cultivation in high yield in 1973, under the correct leadership of party committees at all levels, we have undergone various tests of natural disasters and achieved good results. The yield per mu increased from 474 kg in 1972 to 715 kg in 1976, an increase of 59.3%. The past five years, high-yield plots are stable at the level of more than 900 pounds. In 1976, it overcame natural disasters such as cold and frost at harvest and rainy days at harvest. The average yield per mu of high-yielding crops exceeded 800 kilograms, of which the highest was 1.47 mu and the yield was 962.8 kg per mu. This year in late April severe low temperature, oligospermia and late May pollen mother cell meiosis at low temperatures, there are still 50 acres across the river and a small area of more than 900 pounds field appears. Through five years of testing, now spring wheat high yield cultivation in several technical measures are as follows.
