根据我们在农业生产中多年实践证明,凡是施用磷肥的地块,都有增产的效果。1976年我县进行土壤普查,提供了“缺氮少磷,钾不足”的科学依据,我县严重缺磷面积,占普查面积的56.5%。这已经引起人们的重视,近几年施磷量逐年增加,如1980年用170吨,1981年用580吨(包括复合肥在内)。施磷能促进作物籽粒饱满,块根块茎增加,含
Based on our years of practice in agricultural production, it has been proved that all plots that use phosphate fertilizer have the effect of increasing production. In 1976, the county conducted a soil survey to provide a scientific basis for “lack of nitrogen and phosphorus and insufficient potassium”. The county has a serious phosphorus deficiency area, accounting for 56.5% of the census area. This has drawn people’s attention. In recent years, the amount of phosphorus fertilizer has been increasing year by year, for example, 170 tons in 1980 and 580 tons in 1981 (including compound fertilizers). Phosphorus can promote full crop seeds, tuberous tubers increased, with
