1970—1973年,我们在大通县后子河公社陈家庄基点,对 CCC 进行了防止春小麦倒伏的试验,比较了不同的施用时期、剂量、方式及其对春小麦增产作用的效果。CCC 防止春小麦倒伏,对增产起显著作用最适合的施用时期是分蘖中期及拔节始期。方式与剂量:喷施,每亩用量0.5～1斤;撒施,每亩用量2斤;浸种,每亩用量0.2～0.3斤;沟施,每亩用量2斤。CCC 处理之后,植株茎秆矮粗,叶片短宽而挺立,叶色深绿。群体间透光率增加,抗倒力加强。当前,在栽培品种还未达到一种“理想型”品种的条件下,可作为进一步夺取高产稳产的一项栽培管理技术。在我们的条件下,种子用 CCC 溶液浸种处理的,每亩产量796.5斤,比对照增产10.5%。播种期 CCC 拌砂沟施处理的,每亩产量917斤,比对照增产22.4%。分蘖中期至拔节始期 CCC 拌砂撒施处理的,每亩产量1012斤,比对照增产29.6%,分蘖中期至拔节始期 CCC 溶液喷雾,每亩产量1045斤,比对照增产31.8%,四种处理尤以喷施效果最好,分别较浸种、沟施、撒施增产23.8%、12.1%和3.2%。
From 1970 to 1973, we experimented with CCC to prevent spring wheat lodging in Chenjiazhuang, Houzihe Commune, Datong County. We compared the different application periods, dosages and methods and their effects on the yield increase of spring wheat. CCC to prevent spring wheat lodging, a significant role in increasing production The most suitable period of application is mid-tillering and jointing stage. Method and dosage: spraying, the amount of 0.5 to 1 kg per acre; spreading, 2 kg per acre; soaking, the amount of 0.2 to 0.3 kg per acre; ditch facilities, the amount of 2 kg per mu. After CCC treatment, plant stalks are short and thick, leaves short and wide and stand tall, dark green leaves. Light transmission between groups increased, anti-dumping strengthened. Currently, under the condition that cultivars have not reached a “ideal” variety, they can be used as a cultivation management technique to further seize high and stable yield. Under our conditions, seeds were soaked with CCC solution, yield 796.5 kg per acre, 10.5% more yield than the control. Seeding CCC mixed sand sand treatment facilities, the yield per acre 917 kg, 22.4% increase over the control. CCC mixed with sand from the mid-tillering stage to the jointing stage had a yield of 1012 kg per acre, an increase of 29.6% compared with the control. The CCC solution was sprayed from the mid-tillering stage to the jointing stage with a yield of 1045 kg / mu and a yield increase of 31.8% The spraying effect was the best, respectively, soaking, dunging, spreading yield 23.8%, 12.1% and 3.2%.
