新乐县是花生产区,属沙质土壤,肥力不足,养分含量低,PH 值较高。1990年我们在彭家庄沙滩地搞了施用磷石膏试验,面积200亩,平均增产71.5%;1991年试验,平均增产74.3%,大区施用增产48.01%。施用磷石膏的植株生长势强,成熟期调查10穴双饱果比对照多18个,单饱果少5个,10穴果重比对照多118.5克。增产机制。花生是喜钙作物,适宜在微酸性土壤上生长,而供试土壤的 PH
Xinle County, flower production area, is sandy soil, lack of fertility, low nutrient content, high PH value. In 1990, we experimented with Phosphogypsum in the beach of Pengjiazhuang with an area of 200 mu, an average yield of 71.5%. In 1991, the average yield was 74.3% and that of the large area increased by 48.01%. Phosphogypsum plant growth potential strong maturity survey 10 points double saturation than the control more than 18, a single fruit less 5, fruit weight 10 points 118.5 grams more than the control. Increase production mechanism. Peanuts are hi calcium crops, suitable for growth in slightly acidic soils, but for the test soil pH
