近几年来,许多研究资料证明,水稻苗期对磷素营养的反应特别敏感,早稻秧田集中施用磷肥,可以提高秧苗素质,培育壮秧。去年,我们在早稻育秧时进行了秧田施磷小区试验,供试品种为矮南早39,磷肥种类为过磷酸钙,4月27日播种,5月30日移栽时考查秧苗素质,现将试验结果简述如下:1.可以减少烂秧。试验证明,秧田集中施磷,尤其是在用肥量较多的情况下,可以
In recent years, many research data show that rice seedling response to phosphorus nutrition is particularly sensitive to early rice paddy field concentrated application of phosphate fertilizer, can improve the quality of seedlings, nurturing strong seedlings. Last year, when we planted rice seedling in early rice, we conducted the experiment of phosphorus application in the seedling field. The tested varieties are Dansanzao 39, the type of phosphate fertilizer is superphosphate, sown on April 27 and the quality of seedlings tested on May 30 transplanting The test results are summarized as follows: 1. Can reduce rotten seedlings. Test proved that concentrated phosphorous seedling, especially in the case of more fertilizer, you can
