我区河谷农区肥料、饲料不足,直接影响农牧业生产的进一步发展。这一问题随着冬小麦种植面积的扩大,豆料作物面积的缩小,表现更为突出。为此,我所从1975年再次从国内各省引进多种绿肥饲料作物,并搜集本区各地原有绿肥饲料作物进行试验观察,取得了一些初步结果。但限于人力尚未更广泛地开展试验,更未能在生产上广泛运用。为了我区农牧业生产有一个更大的发展,希望各地能注意开展绿肥饲料作物的试验研究和利用工作。现将我们所取得的资料整理如下,供各地开展这方面工作时参考。
Farming area in our valley fertilizers, feed shortages, a direct impact on the further development of farming and animal husbandry. This problem with the expansion of winter wheat acreage, soybean crop area reduced, the performance is more prominent. To this end, we have again introduced a variety of green manure crops from various provinces in China in 1975 and collected some raw green manure crops from all over the region for experimental observation. Some preliminary results have been obtained. But limited to manpower has not yet carried out a wider pilot, but also failed to widely used in production. In order to have a greater development of agriculture and animal husbandry in our district, I hope all localities can pay attention to the experimental research and utilization of green manure crops. The information we have obtained is now compiled as follows for reference when carrying out work in this regard.
