一项旨在减少水稻生产中的劳动强度和高产栽培的为期三年的项目已经完成。主要研究成果有:水稻覆膜直播播种机的研制、土壤参数测定装置的研制、高产栽培方法的建立和新型肥料的研制。2.湿水稻土硬度计的研制3.最大单产的最佳育苗密度的确定。4.明确了行间行距、行5.确定了三种不同施肥法(常规施肥法、全程施肥法、缓效肥整层施肥法)对水稻生长发育的影响。6.明确了水田水深与单位面积秸秆数的关系。7.建立数学模型,分别描述叶片明暗与有效茎百分率之间的关系,以及与茎长之间的关系。8.明确了穗粒数、第二叶长和第二节间长之间的关系。9.明确追肥次数和追穗次数与单位面积有效茎数和人均籽粒数的关系。10.通过使用叶绿素测定仪的管理实践,根据目标产量确定管理标准。11.引入新参数“茎长密度(m/lt;m^2>)”
英文摘要
A three-year project aiming at reduction of laber and high-yielding culturein rice production has been completed. The achivement includes developments ofthe seeding machine for DSSP (Direct seeding with coated rice in submerged paddyfi eld), a measuring device for a soil parameter, establishment of high-yieldingculture method and new type fertilizer.The followings are reading findings and developments in this project.1.Development of a direct rice seeder with narrow interrow spacing appricators (15 cm-20 cm). 2.Developemt of a soil hardness tester used for wet paddy soil. 3.Determination of optimum establishment of seedling and seeding density for maximum yield per unit area. 4.Clarification of the relationships between interrow spacing,intrarow spacing number of seeds to drill per spot and yield based on land productivity. 5.Confirmation of the effects of three different fertilizer application method (Conventional, fullow-side fertilizer application,whole layer application of slow-acting fertilizer) on the growth of DSSP rice. 6.Clarification of the relationships between water depth of paddy field and number of stems per uint area. 7.Development of mathematical models to describe relationships between light and shade of leaf and percentage of productive stems , and between that and stem length, respectively. 8.Clarification of the relationships between number of grains per head,second leaf length, and second internode length. 9.Clarification of the relationships between times of top dressing and ear manuring and number of productive stems per area and grains per head. 10.Determination of management criteria based on aiming yield by a management practice using the chlorophylemeter. 11.Introduction of a new parameter "Stem length density (m/ <m^2> )"
