红花草子是我省双季稻的当家绿肥。化学磷肥对红花草子增产效果显著,但化学磷肥的生产尚不能满足需要。我省磷矿资源丰富。研究磷矿粉肥对红花草子的肥效及施用方法,对推广利用磷矿粉肥,提高红花草子产量具有重要意义。 本项盆栽试验是配合大田试验示范进行的,目的是和大田试验相互印证,以摸清大田试验示范中提出的一些问题。试验包括:①磷矿粉肥与猪粪堆沤后的肥效;②磷矿粉肥全层施与表层施的肥效比较;③不同矿源(?)
Safflower grass is the double crop of rice in our province headed green manure. Chemical phosphorus fertilizer on the Safflower yield significantly, but the production of chemical phosphate still can not meet the needs. Phosphorus mineral resources in our province is rich. It is of great significance to study the effect of phosphate rock fertilizer on the growth and the application methods of safflower grass and promote the utilization of phosphate fertilizer and improve the yield of safflower grass. This potted plant experiment is carried out in cooperation with the field experiment demonstration, the purpose is to confirm each other and field trials to find out some of the problems raised in the field experiment demonstration. The test includes: ① fertilizer efficiency after phosphate rock manure and pig manure piling; ② fertilization effect of phosphate rock fertilizer on the whole layer and surface layer; ③ different mineral sources (?
