优聪素是一种全水溶、高含量、易吸收的高效叶面肥。其中N(NO3-N)含量为14%,P_2O_5含量为7%,K_2O含量高达39%,总成份大于60%。为探讨该叶面肥对杂交水稻的应用效果,于2014年在宁都县湛田乡井源村的一季晚稻田进行了试验使用,并同万家宝、爱多收叶面肥进行了对比试验。期以同样方法调查,优聪素处理与对照的实粒数分别为242.3粒、215.4粒、210.6粒和157.9粒;成熟期采用五点
Youcong Su is a water-soluble, high content, easy to absorb high efficiency foliage fertilizer. The content of N (NO3-N) was 14%, the content of P2O5 was 7%, the content of K2O was as high as 39% and the total content was more than 60%. In order to investigate the application effect of this foliar fertilizer on hybrid rice, the experiment was carried out in a quarter of late rice paddy in Jingyuan Village, Zhantian Township, Ningdu County in 2014, and compared with that of Wanjiabao and Amorpha. The same method was used to investigate. The actual numbers of gifted and unfrozen treated and control fruits were 242.3, 215.4, 210.6 and 157.9, respectively. The maturity period was five
