我们从1970年开始搞春小麦小面积高产栽培试验,摸索高产稳产规律。几年来,小麦亩产均达千斤以上。1973年种植的“青春5号”高产试验田3.38亩,每亩成穗60.87万,穗粒数34.46粒,千粒重43.17克,亩产1585.3斤。1974年扩大到16.05亩,验收亩产1,512.5斤。1974年我们主要采取了以下栽培措施: 一、打好基础,为高产创造条件我队高产田的前作为小麦连作地。上年9月上旬收获后,对土层比较薄的纯砂地段(约0.45亩)进行了换土。随后灌水,于9月29日用马拉步犁耕翻,耕深17厘米。翻前每亩施有机肥16,500斤。耕后晒垡60天左右。当年11月下旬,按规划平整土地,小区面积0.1—0.2亩。11月下旬至1974年1月下旬,复平土地三次,挖拣小麦残茬二次,土地基本做到平整。
We started from 1970 to engage in spring wheat small-area high-yielding cultivation experiment, explore the law of high yield and stable yield. In recent years, wheat mu produce up to a thousand pounds or more. In 1973, “Youth No. 5” high-yield experimental field of 3.38 mu, per acre into a peak of 608,700, 34.46 grains per spike, grain weight 43.17 grams, 1585.3 kg per mu. 1974 expanded to 16.05 acres, acceptance of 1,512.5 kg per mu. In 1974 we mainly adopted the following cultivation measures: First, lay a good foundation to create conditions for high-yielding Our team before the field of high yield wheat as the land. After harvesting in early September last year, soil replacement was carried out on the relatively thin pure sand area (about 0.45 mu). Subsequent irrigation, on September 29 with Mara Step Plow plowing, plowing 17 cm deep. Turned 16,500 pounds of organic fertilizer per mu before turning over. Plow 60 days after drying. In late November of that year, according to the planning of the land, the plot area of 0.1-0.2 acres. From late November to late January 1974, the land was planted three times in succession, the wheat stubble was dug twice and the land was basically flat.
