邵东丘陵紅壤稻田普遍缺磷,施用过磷酸鈣不仅能有效地防止鴨屎泥和冷浸田等“翻秋”之害,而且使水稻产量成倍增加。因此,过磷酸鈣在全县广大农村深受欢迎,經常脫銷。省委为了滿足生产单位的需要,就积极发展鈣鎂磷肥。但是,鈣鎂磷肥是一种新品种,可否代替过磷酸鈣和大面积合理施用技术問題等,尙缺乏試驗資料。为此,我所1964年在邵东县采取农村基点、农业技术推广站和試驗場三結合的方法,进行鈣鎂磷肥肥效試驗研究。茲将試驗
Shaodong hilly red rice paddy fields in general lack of phosphorus, the application of superphosphate can not only effectively prevent duck feces mud and cold dip fields and other “fall autumn” harm, but also doubled the yield of rice. Therefore, SSP in the vast rural counties popular, often out of stock. Provincial Party Committee in order to meet the needs of production units, to actively develop calcium magnesium phosphate. However, the calcium magnesium phosphate is a new species, can replace the superphosphate and a large area of rational application of technical problems, 尙 lack of test data. To this end, I in 1964 in Shaodong County, rural areas to take base, agricultural technology extension station and the combination of three test sites, the effect of calcium magnesium phosphate fertilizer test study. Will test
