淮北水稻持续高产技术途径探讨

Discuss on Technology Paths of Sustained High Production on Rice in Huaibei

江苏省十多年来水稻单产一直徘徊不前,其主要原因除缺乏广适的、增产潜力大的水稻新品种外,在栽培技术上,由于传统手栽、塑盘抛秧、机械栽插、直播等多种栽培方式并存,导致高产栽培配套技术应用不能到位,已成为进一步提升全省水稻单产的障碍。本文通过对手栽、塑盘抛秧、机械栽插、直播等多种栽培方式的试验研究,探讨淮北稻区水稻持续高产技术途径,解决该区稻麦周年生产季节矛盾突出,时常干旱缺水,农田基本建设脆弱,务农劳力匮乏等问题。

For more than 10 years, the main reasons on stagnant of rice yield in Jiangsu were expounded exception of lacking new rice varieties on eurytopicity and big yield improving potential, the suitable sets of planting technology were inadequate because of exist alongside traditional cultivation technique, plastic-plate-throwing transplantation, mechanized seeding technology and direct sowing, they were obstacle to increase the yield, the test of traditional cultivation tech- nique, plastic-plate-throwing transplantation, mechanized seeding technology and direct sowing were made discuss efficient ways to increase yield, solve the questions such as contradiction of produce season between rice and wheat, Water short- age, farmland capital construction were lagged, lack the huge work force et al.
