江苏吴县无机化工厂生产的CPO—Ⅰ型供氧剂是以过氧化钙为主的多种营养元素的白色、无毒、粉状物。具有供氧和肥效的特殊产品。为了验证其功效,在四川省成都和广汉等地做了多项试验,其主要结果及供氧剂的性质综述如下。 一、CPO—Ⅰ型供氧剂的应用试验 1.玉米种子供氧剂包衣有提高出苗数,增加植株高度和增产的作用 供试种“高油6号”,以干种子重量30％秤取CPO—Ⅰ,加水调成糊状,干种子在糊状CPO—Ⅰ中滚动,就成了包衣种子。1993年3月29日播种,每穴4粒,设处理和对照。出苗后各调查34穴,136粒,处理者出苗42株,比对照31株多8.2％,其中每穴出苗2、3、4株的株率,对照依次少23.9％,48％和100％。收获时的株高:处理者268.9厘米,比对照243.7厘米高10.3％。收后考种:玉米果穗的
Jiangsu Wu County inorganic chemical plant production CPO-Ⅰ-type oxygen supply is a calcium peroxide-based variety of nutrients in white, non-toxic, powder. With oxygen and fertilizer efficiency of special products. In order to verify its efficacy, a number of tests have been conducted in Chengdu and Guanghan in Sichuan Province. The main results and the nature of oxygenating agents are summarized as follows. First, the application of CPO-Ⅰ oxygen agent test 1. Corn seed oxygen agent coating to increase the number of emergence, increase the plant height and the role of increased yield for the test “high oil 6” to dry seed weight 30% scale Take CPO-Ⅰ, add water into a paste, dry seeds in paste CPO-Ⅰ rolling, became a coated seed. March 29, 1993 sowing, four per hole, set treatment and control. After the emergence, 34 points and 136 grains were investigated, 42 of which were treated by the treatment, 8.2% more than the control, respectively. The strain rates of 2, 3, and 4 plants per shoot were 23.9%, 48% and 100% lower than that of the control. Plant height at harvest: Processor, 268.9 cm, 10.3% higher than control 243.7 cm. After the test seed collection: corn ear
