在有效态铜较低的土壤上施铜肥有明显增产作用。种子经硫酸铜拌种后可以显著提高小麦的发芽率。为此分别进行了不同剂量的硫酸铜拌麦种的室内发芽率试验和田间幼苗感病率调查。试验是在两个农场同时进行的。硫酸铜拌种的用量分别为种子重量的1%、0.3%和0.05%。拌种方法是:用相当于种子重量2%的清水,将硫酸铜溶解后,边喷洒边拌种,然后堆放闷种12～17小时再播种。以
In the effective state of copper on the lower soil fertilizers have significantly increased yield of copper. Seeds after copper sulfate seed dressing can significantly improve the germination rate of wheat. To this end, different doses of copper sulfate mixed wheat indoor germination rate test and field seedling susceptibility survey. The experiment was conducted simultaneously on two farms. The amount of copper sulphate seed dressing was 1%, 0.3% and 0.05% of the seed weight, respectively. Seed dressing method is: with the equivalent of 2% by weight of seed water, the dissolution of copper sulfate, while spraying while dressing, and then stacked bored species 12 to 17 hours before sowing. To
