近年来随着稻麦面积的扩大,复种指数增加,水源日感不足,加之初夏干旱,又缺乏相应的栽培措施,水稻产量出现了徘徊的局面。1979年以来,我县针对上述影响麦茬水稻高产的主要矛盾,采取了“稀播育壮秧,插秧减少基本苗,合理使用肥水和稻田化学除草”的措施,即省种、省水、省肥、省工(简称“四省”)高产栽培技术,并于1981年开始进行推广应用,取得明显效果。现将“四省”栽培技术要点及应用效果分析如下:
In recent years, with the expansion of the area of rice and wheat, the increase of multiple cropping index, the lack of water quality, combined with the drought in early summer and the lack of corresponding cultivation measures, the output of rice has been hovering. Since 1979, our county has adopted the measures of “thinning and breeding strong seedlings, reducing basic seedling by planting seedlings, rational use of fertilizers and chemical weeding in rice fields” according to the above major contradictions that affect the high yield of wheat stubble, that is, provincial species, provincial water and provincial fertilizers , Provincial workers (referred to as the “four provinces”) high-yielding cultivation techniques, and in 1981 began to promote the use and achieved significant results. Now “four provinces” cultivation techniques and application of the results as follows:
