近年来,为了进一步探索小麦高产的适宜土壤,我们从大田生产出发,在深翻土地的基础上,着重探讨了深翻结合施肥,即改良土壤和合理使用化肥,在促进小麦增产方面取得了成果,全大队小麦亩产由一九七四年的579斤提高到一九七八年的917斤,79年虽受“倒春寒”及后期干热风气候袭击,小麦单产仍获得了873斤的好收成。现将我们在培肥土壤,合理使用化肥方面的试验资料整理如下,供参考。 In recent years, in order to further explore the suitable soil for high-yielding wheat, we started from the field production. On the basis of deep-turning the land, we focused on the deep-turning combined fertilization, that is, improving the soil and using fertilizers reasonably, . The output of wheat in the entire brigade increased from 579 kg in 1974 to 917 kg in 1978. Despite the “late spring cold” and the dry-hot wind weather in the latter half of the year, wheat yields of 873 kg were still well received . Now we fertilize the soil, the rational use of fertilizers test data are summarized below, for reference.
