发展旱稻生产是我省沿江旱三熟制地区开辟细粮资源、增加秋粮产量的一条经济有效的新途径。1990年试种8000亩,1991年发展到6万亩左右。随着面积的不断扩大,及时防除杂草已成为旱稻高产栽培技术体系中的重要一环。本文则根据近几年旱稻生产示范点的考察调查,简要阐明旱稻田杂草的生态特点及其防除对策,以供有关生产部门及广大旱稻农户参考。一、旱稻田杂草的生态特点目前,旱稻推广种植主要在我省沿江地区淡水资源贫乏的启东、海门、如东、海安等县
The development of upland rice production is a new economic and effective way to open up fine grain resources and increase the output of autumn grains in the three dry farming areas along the Yangtze River in our province. 8000 acres planted in 1990, developed to about 60,000 acres in 1991. With the continuous expansion of area, timely control of weeds has become an important part of high-yielding cultivation techniques for upland rice. Based on the investigation and investigation of the demonstration sites of Upland rice production in recent years, this paper briefly describes the ecological characteristics of weeds in Upland rice and its control measures for the reference of the relevant production departments and the majority of Upland rice farmers. First, the ecological characteristics of arid rice field weeds At present, the promotion of Upland rice cultivation mainly in the Yangtze River in our province freshwater resources Qidong, Haimen, Rudong, MSC and other counties
