我乡有粮田面积23535亩,属中低产地区,常年粮食均产在700kg左右。随着产业结构的调整和“一优两高”农业的发展,承包大户迅速增加。这些承包大户由于劳力缺乏,季节紧张,造成单位面积产量和经济效益偏低。为探索农田投入低成本,产出高效益的新路子,提高规模经营效益,我们在1992年作了单季撒直播试验,1993年扩大示范早稻188亩,晚稻821亩的基础上,1994年早稻推广撒直播面积1325亩,晚稻推广撒直播面积813亩,收到了水稻生产省工、省本、高产、高效的结果。现将撒直播的经济效益及主要栽培技术总结如下。 My rural area of ​​23,535 acres of grain fields, is a low-yield areas, perennial grain production in about 700kg. With the adjustment of industrial structure and the development of agriculture, the large contractors have rapidly increased. Due to the lack of labor and seasonal tension, these large contractors caused low output per unit area and low economic returns. In order to explore the farmland into a new low-cost, high efficiency and output of new ways to improve the scale of operating efficiency, we made a single seeding live broadcast test in 1992, in 1993 to expand demonstration demonstration of 188 mu of early rice, 821 mu of late rice, based on the 1994 morning rice Popularize 1325 acres of broadcast live broadcast, spreading late rice to spread live broadcast coverage of 813 acres, received the provincial, provincial, high-yielding and efficient results of rice production. Broadcasting broadcast now is the economic benefits and the main cultivation techniques are summarized below.
