水稻基质板育秧试验研究

近年来,水稻种植机械化水平不断提高,但仍存在一些亟待解决的难题,制约了水稻生产。在黑龙江高寒地区,春季育苗存在用土量较大、化冻慢,不能适时育苗、秧苗素质不稳等多种因素影响了水稻农业生产。通过大量试验示范表明,采用基质育秧无需到田间大量取土,解决了田间取土难问题,同时避免了采挖客土带来的杂草籽多、土传病害、药害现象的发生,既保护了环境,又实现了农业有机固废资源化高值利用,推动了水稻育秧向规模化、集约化、产业化、基质化发展。

Study on Rice Substrate Plate Seedling

In recent years,the level of rice planting mechanization has been increasing,but there are still some difficult problems to be solved,which restrict rice production.In the Alpine region of Heilongjiang,the agricultural production of rice is affected by many factors,such as large amount of soil,slow thawing in spring,untimely seedling raising and unstable seedling quality.Through a large number of experiments and demonstrations,it is shown that it is not necessary to take a large amount of soil in the field to raise seedlings with the substrate,which solves the problem of difficult soil collection in the field,and at the same time avoids the occurrence of many weed seeds,soil-borne diseases and medicaments brought about by the excavation of alien soil,thus protecting the environment,the high-value Utilization of agricultural organic solid waste resources has also been realized,which has promoted the development of rice seedling raising to large-scale,intensive,industrialized and matrix.
