摘要
干旱缺水是影响旱作农业的重要因素,研究旱作节水技术是保证国民经济正常发展和农业可持续发展的前提和基础。流体播种是一种抗旱、节水、增产的新技术。为此,在调查和试验研究的基础上介绍了流体播种技术及其在节水,提高出苗率、成活率等方面的特点;简述了保水剂的发展和应用情况以及流体播种机具的研究现状;分析了影响流体播种技术应用的排种器伤种、流体播种液的配制、播种精度和均匀度、保水剂的使用经济性等关键技术问题,并探讨了其解决措施,可为流体播种技术和播种机具的研究提供参考。
Drought is critical problem in agricultural production; water-saving technique in dry farming is significant for sustainable agricultural development and the national economy. Fluid seeding is a new drought relief technique which can save water and increase yield. On investigation and experimental study, this paper introduces fluid seeding technique and it＇s features in saving water, increasing germination and increasing the survival rate of the seedlings, describes the development and application of water-conserving agent, reports the research and achievements on fluid seeding machines, analyzes the key problems and counter measures of application of fluid seeding, such as seed damage by metering device, preparing water conserving agent solution, precision and evenness of seeding, economical effect of water conserving agent utilization, etc. This paper may provide references for the study on fluid seeding technique and sowing machines.
