根据在有效态锌元素含量较低的土壤中,适当补施一定数量的锌肥,可以提高农作物产量。为此,我所对玉米进行了锌肥试验。一、试验概况试验地系湃阳河边冲积性沙土。据分析,有效锌含量为0.3972PPm。前作油菜,油菜收后,机耕、耙各一次,于6月8日播种玉米。品种为当地良种“二黄早”。试验设亩施锌肥6斤、4斤、不施三种处理,锌肥用作底肥一次施下。每处理重复三次,随机区组排列。小区面积7.5 x4二32平方米(合0.045
According to the effective content of zinc in the soil is low, appropriate replenishment of a certain amount of zinc fertilizer, can increase crop yields. For this reason, I conducted a zinc fertilizer test on corn. First, the test profile Test to the alluvial river surging Pai Yang sand. According to the analysis, the effective zinc content is 0.3972PPm. Before rapeseed, rapeseed after harvesting, plowing, raking each time, on June 8 sowing corn. Varieties for the local seed “two yellow early.” Test set mu fertilizer zinc 6 pounds, 4 pounds, do not apply three kinds of treatment, zinc fertilizer used as a base fertilizer once. Each treatment is repeated three times, randomized block arrangement. Area of ?? 7.5 x4 two 32 square meters (together 0.045
