旱地在柳州地区分布面积较大,约占耕地总面积50％。这部分旱地,由于干旱缺水,土瘦缺肥,耕作粗放,历来单产很低,特别是旱粮低而不稳;各地针对当地自然环境特点,进行了多种不同耕作制度的改革试验,经多年实践,证明用玉米黄豆间套种轮作复种这样一个生物群体,去适应当地自然环境特点,能稳产、增产,又比较经济,因而黄豆种植面积迅速扩大,1982年全地区黄豆面积已达102万亩,超过常年三倍以上。为总结这些经验,我们在来宾、忻城、武宣等地进行大面积调查,并从六十年代初开始,断断续续在所内进行一些定点研究,现将调查研究的结果报道如下。
Dry land in Liuzhou area distribution larger, accounting for about 50% of the total arable land. This part of dry land, due to drought and water shortage, lack of soil and thin, extensive farming, has always been a low yield, especially low and unstable grain supply; various local characteristics of the natural environment, conducted a variety of different farming system reform test, Years of practice proved that inter-cropping with corn and soybean intercropping such a biological group, to adapt to the characteristics of the local natural environment, can be stable, increase production, and more economical, and thus the rapid expansion of soybean acreage, soybean area in 1982 reached 1020000 acres , More than three times more than normal. To sum up these experiences, we conducted a large-scale survey in the guests, Xincheng, Wuxuan and other places. Since the early 1960s, we have conducted some targeted studies in-house and intermittently, and the results of the investigation and study are reported below.
