滕县小麦丰产栽培的趋势是,随着生产条件,特别是地力水平的提高,行距在扩大,播量在减少,春季水肥要推迟,群体相应地缩小。大面积丰产栽培的实践证明,创千斤以上小麦高产,必须根据生产条件,合理地利用分蘖成穗。过去,我们使用分蘖力较弱、穗重较高的“阿夫”品种,在土壤肥力较差,茬口较晚的情况下,靠主茎成穗的途径,搞出一批千斤丰产田。随着地力水平的提高,品种的更换,靠主蘖并重的途径,使千斤田的面积,进一步扩大。如1973年,史村大队使用“2411”品种,每亩基本苗22万,成穗48.8万,穗重1.06克,亩产1,030.8斤(8.6亩);近三年,随着地力的增强,播期的提前,穗重潜力较大的“百泉”品种的引进,对分蘖的利用数量有所增加,
The trend of high yield wheat cultivation is that with the improvement of production conditions, especially the improvement of soil fertility, the row spacing is expanding and the amount of sowing is decreasing. The spring water and fertilizer should be postponed, and the population should be reduced correspondingly. The practice of large-area high-yield cultivation has proved that it is necessary to make high-yielding wheat above a thousand kilograms and make rational use of tillering into ear according to the production conditions. In the past, we used “Afu” varieties with weaker tillering ability and higher panicle weight to produce a large number of high-yielding fields under the condition of poor soil fertility and later stubble. With the improvement of geotechnical level, the replacement of breeds and the multiplication of main tillers will further increase the area of cropland. As in 1973, the history of the village brigade using “2411” varieties, basic seedlings per acre 220,000, 488,000 spike, spike weight 1.06 grams, 1,030.8 pounds per mu (8.6 acres); the past three years, with the enhancement of fertility, The introduction of the “Baiquan” cultivar, which has a higher potential for spike weight, has an increase in the utilization of tillers,
