我省历年栽培辣椒亩产6,000～8,000斤,七十年代产量逐渐下降.沈阳市南塔大队1965年平均亩产6,000～7000斤,1975年亩产1,000斤,1976年仅产500斤.全省辣椒科研协作网经过三年研究试验,认为定植期的低温冷害、定植后管理不善、6～7月份高温曝晒和病毒蔓延等是造成辣椒低产的原因.如果进行前期短期覆盖,则能提高地温,保持土壤水分,使植株上下部都能生长健壮,可提高抵抗外界不良环境条件的能力.据1978年省园艺所试验,覆盖的折亩产3,55 7斤,比对照2,572斤增产38.2%,前期增产效果则更为明显.海城县荒岭子大队覆盖的折亩产9,930斤,是对照的426%;营口柳树公社东柳二队覆盖的亩产达14,346斤.
The annual output of peppers in the province has been increased from 6,000 to 8,000 kilograms per mu in the past years, and the output in the 1970s has been gradually declining. The Nanta Brigade in Shenyang City averaged 6,000 to 7,000 kilograms per mu in 1965, 1,000 kilograms per mu in 1975 and 500 kilograms in 1976. The province After three years of research and experiments, the research network of chili peppers believed that the low temperature chilling injury during planting and poor management after planting, the high temperature exposure and virus spreading in June to July are the causes of the low yield of pepper.If the pre-term short-term coverage can increase the soil temperature, Maintain the soil moisture, so that plants can grow robust upper and lower, can improve the ability to resist the adverse environmental conditions.According to the 1978 provincial horticultural test, covering 3.55 7 kg per mu, compared with 2,572 catties increased by 38.2% The yield increase in the early stage was even more pronounced, with 9,930 kg of mu per unit covered by the Xialezi Sub-unit of Haicheng County, accounting for 426% of the control. The mu yield covered by the Liuliu Second Team of Yingliu Willow Commune amounted to 14,346 kg.
