我省红黄壤土地面积9,761.1万亩,其中耕地为3,068.5万亩,占全省耕地面积的30％,仅温江地区就有红黄壤130多万亩。该区普遍存在着不同程度的“三害”(湿害、草害、病害)和土壤肥力低等问题,严重地影响着大、小春作物产量的提高。针对这个问题,我们于1981年9月在邛崃县卧龙公社二大队二队建立了红黄壤低产变高产中试点,运用现有各专业的科研成果和先进技术,对红黄壤进行了综合治理,取得了显著的增产效果。全队55.45亩小麦平均亩产608.1斤,比1981年80.1亩平均亩产278.8斤每亩增产329.3斤,单产提高1.18倍,总产比1981年22,330斤净增11,389.1斤,增产51％,产值增加2,847.3元。油菜91.97亩(集体耕地67.85亩,自留地24.12亩),平均亩产275.7斤,比1981年37亩平均亩产196.2斤每亩增产79.5斤,总产
The area of red-yellow soil in our province is 97,611,000 mu, of which 30,685,000 mu are arable land, accounting for 30% of the arable land in the province. There are over 1.3 million mu of red-yellow soil in Wenjiang alone. There are widespread problems of “three pests” (wet damage, grass damage, diseases) and low soil fertility in the area, which seriously affect the increase of crop yield of big and small spring. In response to this problem, in September 1981, we established a pilot project of low-yielding and high-yielding red-yellow soil in the Second Team of the Second Brigade of Wolong County, Qionglai County. Using the existing scientific research achievements and advanced technologies of various professions, we comprehensively managed the red-yellow soil to obtain A significant increase in production. The team average yield of 608.4 kilograms of 55.45 acres of wheat than in 1981, an average of 80.1 acres per mu 278.8 kg yield 329.3 kg per mu, yield increased by 1.18 times the total output of 22,330 pounds in 1981 net increase of 11,389.1 pounds, an increase of 51% increase in output value 2,847.3 yuan. Rape 91.97 mu (67.85 mu of collective farmland and 24.12 mu of reserved land), with an average yield of 275.7 kg, an increase of 79.5 kg compared with the average yield of 196.2 kg per mu in 37 mu in 1981,
