广西的旱地面积为1420.4万亩,占耕地面积的36.6％。旱地最多的百色地区占耕地面积的58％,该地区有55％左右的乡村人民以旱粮为主食。河池、柳州、南宁三地区亦有类似情况。但旱地作物的产量和产值均很低。为此,我们组织了旱地协作攻关组,组织以增产旱粮为主的粮、经、肥、饲相结合的旱地分带间、套、轮作多熟制的试验研究,共同探讨提高旱地作物的单产和年总产 The dry land area in Guangxi is 14,204 mu, accounting for 36.6% of the total cultivated land area. Baise, with the largest dry land, accounts for 58% of the arable land. About 55% of rural people in this region depend on dry land for food. Hechi, Liuzhou, Nanning, three areas have similar situations. However, the output and value of dryland crops are low. To this end, we organized a dryland collaborative research group to organize experimental studies on multi-cropping of dryland with grain yield, grain yield, grain yield, fertilizer and feedstuffs, Yield and annual output
