1965年,我所样板田作了珍珠矮高产示范栽培829宙,平均单产904斤,其中有136.9亩,获得每亩1,030斤。在进行栽培示范的过程中,我们进行了施肥技术的调查研究和科学试验工作,现将所得结果初步总结如下。 一、珍珠矮的需肥特性 样板田的土壤为冲积平原油砂土,砂性重,速效养分释放快,保肥力不好,肥料容易损失(土壤物理性粘粒31.9％,土壤代换 In 1965, I made a demonstration of paddy short high-yielding demonstration cultivation of 829 hectares, with an average yield of 904 kg, of which 136.9 acres, 1,030 kg per acre. In the process of cultivation and demonstration, we conducted a survey of fertilization technology research and scientific experiments, the results obtained are summarized below. First, pearl short fertilizer characteristics Sample field soil alluvial plain oil sand, heavy sand, fast-acting nutrient release fast, poor fertility, fertilizer easily lost (31.9% of soil physical clay, soil replacement
