我县地处赣西北山区,中、低产田面积较大,土壤普遍缺磷,严重影响水稻的早发及穗粒性状,对产量影响极大。为了探索在我县土壤件条下水稻田对磷肥的吸收和利用的特性及不同磷肥用量的增产效应,寻求磷肥的最佳用量,去年,在何市乡进行了磷肥不同用量试验,为合理施用磷肥,提高磷肥的经济效益,提供科学依据。
My county is located in the mountainous area of northwestern Jiangxi Province. The area of medium and low yield fields is large and the soil is generally deficient in phosphorus, which seriously affects the characteristics of early-onset and spike grain of rice and has a great impact on the yield. In order to explore the paddy soil under my works on the absorption and utilization characteristics of phosphate fertilizer and phosphate fertilizer production effects of different yield and seek the best use of phosphate fertilizer last year in Hexiang Township conducted a different dosage of phosphate fertilizer test for the rational use of phosphate fertilizer , Improve the economic benefits of phosphate fertilizer, to provide a scientific basis.
