在毛主席无产阶级革命路线的指引下,随着“农业学大寨”群众运动的深入发展,一个群众性的土壤肥力鉴定和作物营养诊断工作正在我省蓬勃兴起。为了适应这一工作的需要,本期刊登了兴平县西吴公社土壤肥力普查报告,供各地参考。耕作土壤是农业生产的基础。作物在它生长的全过程中所需要的营养都来源于土壤。土壤肥力的高低将直接影响作物产量。为了适应和发展农业生产的大好形势,调查土壤肥力状况与植物营养诊断,结合观察作物的外部形态,可以及时了解作物体内的营养状况和土壤的供肥水平,进行经济合理培肥,不断提高土壤供肥能力,建设高产稳产农田,大幅度提高作物产量,实行科学种田,具有重大的现实意义。我省广大贫下中农和革命干部,在四届人大精神的鼓舞下,在学习外省先进经验的基础上,正在开展这方面的工作,从当前来看,西安市郊、榆林都进行了试点工作。汉中县于今年三、四月全面展开了普查工作。宝鸡市专门成立了土壤普查与作物营养诊断领导办公室,并于今年四月在岐山县召开了六县土壤普查工作会议,举办了试点学习班。目前,宝鸡、岐山、风翔、眉县、扶风、武功先后都在进行试点工作,准备全面普查。为了尽快的把我省农业生产搞上去,希望各地技术单位,积极行动,紧密配合,逐步开展此项工作。——编者 Under Chairman Mao’s proletarian revolutionary line, with the deepening development of “Dazhai Agricultural Studies” and mass movements, a mass identification of soil fertility and diagnosis of crop nutrition are beginning to flourish in our province. In order to meet the needs of this work, this issue published a survey report on soil fertility of Xixi commune in Xingping County for reference. Farming soil is the basis of agricultural production. The nutrients that the crop needs throughout its growth come from the soil. The level of soil fertility will directly affect the crop yield. In order to adapt to and develop the good situation of agricultural production, to investigate the status of soil fertility and plant nutrition diagnosis, combined with the observation of the external shape of crops, we can understand the nutritional status of crops and the level of soil fertilizers in time and carry out economic and rational fertilization to improve soil It is of great practical significance to provide fertilizers, build farmland with high and stable yield, greatly increase crop yield and implement scientific farming. Inspired by the spirit of the Fourth National People’s Congress, based on the advanced experience of other provinces, the vast majority of the poor peasants and middle peasants and revolutionary cadres in our province are carrying out their work in this respect. From the current point of view, the pilot projects in the suburbs of Xi’an and Yulin are under way. Hanzhong County launched a comprehensive census work in March and April this year. Baoji City set up a special office for soil census and crop nutrition diagnosis. In April this year, six county-level soil census work meetings were held in Qishan County, and a pilot study class was held. At present, Baoji, Qishan, Fengxiang, Meixian, Fufeng and Wugong have conducted pilot work in preparation for a comprehensive survey. In order to speed up the agricultural production in our province, I hope all the technical units, active action, work closely with and gradually carry out this work. --editor
