国内外研究者在锌肥研究方面进行了不少工作,但有关田间试验的报告,数量尚少。我们在1970—1978年的工作中,曾多次涉及石灰性土壤玉米锌肥肥效的问题。1979—1981年进行多点试验,1982年与黄陵县农业局,武功、眉县农科所和扶风揉谷公社等单位协作,选择有代表性的地块进行对比示范和小区试验。示范面积6.42万亩,试验小区100多个(实收88个),均取得较好的结果。一、试验设计 (一)田间试验 1.1979年设如下处理,重复3次,3×3拉丁方排列。
Researchers at home and abroad have done a lot of work on zinc fertilizer research, but the reports on field trials are still small. In our work from 1970 to 1978, we talked a number of times about the efficiency of corn zinc fertilizers in calcareous soils. In 1979-1981, a number of experiments were conducted. In 1982, in cooperation with units such as Huangling County Bureau of Agriculture, Wugong, Meixian Agricultural Science Bureau and Fufeng Rough Valley Commune, representative plots were selected for comparative demonstration and plot experiment. Demonstration area of 64200 acres, more than 100 pilot area (received 88), have achieved better results. First, the experimental design (A) field test 1. 1979 set up the following treatment, repeated 3 times, 3 × 3 Latin side arrangement.
