为了配合我省大力开展的间作套种的需要,结合教学工作,我们于1976年在户县进行了小麦边际效应的试验。试图摸清小麦边际效应的深度、大小及其与行、株距的关系等问题。现将试验结果报告于后。一、试验简况试验地设在户县东关农场,前茬是春播自交系玉米,地力甚好。试用品种为分蘖力强的“矮丰三号”。75年10月18日开沟点播,翌年6月14日收割。生长期中冬灌一水,中耕两次,追肥三次,每亩(麦带净面积)共追施硝酸铵100斤/亩左右,作到了肥饱水足,管理及时,生长正常。仅仅后期受赤霉病轻度为害和稍有青干现象。
In order to meet the needs of intercropping and intercropping in our province, combined with teaching work, we conducted a test of wheat marginal effect in Huxian County in 1976. Trying to find out the depth, size of wheat’s marginal effect and its relationship with row and spacing. The test results are reported later. First, the experimental profile Experimental site located in the Huxian Dong Guan farms, the former crop is spring sowing inbred lines of corn, soil very good. Trial varieties for strong tiller “Aphrodite three.” October 18, 75 Ditching on-demand, the harvest on June 14 the following year. Winter irrigation in the growing season, cultivator twice, topdressing three times, per acre (wheat net net area) a total of 100 kg of ammonium nitrate chase, made of fat enough water enough to manage timely and normal growth. Only slightly affected by the scab and sclerenchyma later slightly dry phenomenon.
