汉沽农场四分场地势低洼盐碱,远离自然河道,虽一向以种植水稻为主,但一直靠机井灌溉。所以,长期处于耗能大、成本高、效益低的生产状况。为了扭转这一不利局面,1992年全面推行了水稻小苗旱育稀植机插新技术,并在当年即取得了平均亩产550公斤,比1991年常规稻亩增产9.4%,亩成本下降20.50元的好成绩。为了推广这一新技术,现将他们的经验介绍如下: Hangu farm quarter of low-lying low-lying saline-alkali, away from the natural river, although rice has always been the main planting, but has been by well irrigation. Therefore, long-term energy consumption, high cost, low efficiency of the production status. In order to reverse this unfavorable situation, in 1992 the rice seedling cultivation and cultivation and sparse planting and planting technology was introduced in an all-round way. In the same year, it achieved an average yield of 550 kilograms, an increase of 9.4% over the conventional rice mu in 1991 and a decrease of 20.50 yuan in mu cost Good grades. In order to promote this new technology, their experience is now introduced as follows:
