一、耕作保墒在北部黑土地区的重要意义借助于土壤耕作技术克服春季干旱,在东北北部黑土地区具有不容忽视的意义.下列实例,是最好的证明.在一九五九年春旱严重的年景里,在采取了较良好耕作措施的耕地上,在春旱的条件下,小麦仍有可能获得1,500—1,700公斤公顷的产量,这个产量接近于一九五五年小麦丰收年的地区平均产量(1780公斤/公顷).但在耕作粗劣的地上,产量急剧减低.试举6月25日在红五月农场调查研究结果(表1)加以说明.
First, the importance of tillage and soil moisture conservation in the northern black soil areas With the help of soil tillage technology to overcome the spring drought, it has the significance of being neglected in the black soil areas of northern Northeast China. The following examples are the best proofs. In the severe drought year of 1959 In the view of the land, cultivated land with better farming practices is still likely to yield 1,500-1,700 kilograms of hectares of wheat under spring drought conditions, which is close to the average regional output of the 1955 wheat harvest year (1780 kg / ha), but the yield was drastically reduced on the poorly plowed land and the results of the survey on May 25 in Red May Farm (Table 1) were cited.
