近几年,随着农村产业结构的调整,使乡村部分农业劳动力转移到工副业生产上,粮食生产出现了较大土地面积的专业承包户和专业联营户。目前农户迫切需要一种简便易行、产量较高的水稻种植方式。为此,我们与郊县5个农业技术推广中心,总结了前几年的研究资料,根据直播稻的生育特性,提出了相应的栽培技术措施。直播稻与移栽稻相比,其生长与栽培特点是:播种期较移栽稻为迟,全生育期和总叶片数相应短少;直播稻根浅,根系分布大多在土壤表层:生长前期群体小,个体营养面积较大,分蘖成穗率高,空秕率亦低,因此与移栽稻在产量结构上有所不同。根据直播稻的这些特点,要充分发挥其丰产性能,在栽培技术上,应抓住防止倒伏和防除草害等五项
In recent years, with the adjustment of the industrial structure in rural areas, part of the agricultural labor force in rural areas has been transferred to the production of sideline and sideline products. There has been a large number of professional and contractual households in grain production. At present, farmers urgently need a simple and easy way to produce more rice. To this end, we and suburban five agricultural technology promotion center, summed up the research data in previous years, according to the characteristics of direct-seeded rice, put forward the corresponding cultivation techniques and measures. Compared with transplanting rice, the direct seeding rice had the characteristics of growth and cultivation as follows: the sowing date was later than that of transplanting rice, the whole growth period and the total number of leaves were short; the direct seeding rice roots were shallow and the roots were mostly distributed in the soil surface: Small, individual nutrient area larger, tillering into the ear, the empty rate is also low, so with the transplanted rice in the yield structure is different. According to these characteristics of direct-seeded rice, it is necessary to give full play to its high yield performance, cultivation techniques, should take to prevent the lodging and grass control and other five
