花生玉米间作是我县的传统种植方式,历年都有一定的种植面积。近年来,随着科学种田水平的提高,对这一种植方式的经济效益提出了异议,大致有两种看法:一种认为,花生间作玉米,经济效益是高的,可以推广;另一种认为,间作的经济效益低,多收的玉米补偿不了花生的产量损失。为搞清这个问题,1985年我们进行了多点调查。 一、花生玉米间作的产量效应 花生田间作玉米,花生的产量受到较大影响。据对六个点考查所得的资料分析,种植7行“伏花生”的畦面一侧间作两行丹玉6号玉米,靠近玉米的第一行花生折合亩产花生果平均为229斤,比对照(指 Peanut and corn intercropping is a traditional planting method in our county, and has a certain planting area over the years. In recent years, with the improvement of the scientific farming level, the economic benefits of this planting method have been challenged. There are basically two opinions: one is that the peanut intercropping with corn has high economic benefits and can be popularized. Another is that , Intercropping low economic benefits, overcharged corn can not compensate for the loss of peanut yield. In order to clarify this issue, we conducted a number of investigations in 1985. First, the yield of peanut-corn intercropping Corn for the field of peanut, peanut production is greatly affected. According to the analysis of the data obtained from the six points survey, planting 7 rows of “peanut” noodles side to make two rows of Dan Yu 6 corn, near the first line of corn peanut yield per mu equivalent of 229 kg, Control
