我省杂交水稻制种生产基地相对稳定,年度间组合变化较少,随着化肥用量急剧增加,有机肥投入较少,土壤缺素状况日益突出。特别是抽穗扬花期由于喷施九二○,穗茎节拉长,加上割去部分功能叶,营养缺乏症明显,急需新源微量元素补充。由浙江农业大学土化系监制,浙江省龙游县溪口化工厂生产的作物营养素,由氮、磷、钾及硼、锌等
The hybrid rice seed production base in our province is relatively stable, and there is less change in combination between the years. With the sharp increase in the amount of chemical fertilizers, less organic manure is input, and the status of soil deficiency is becoming increasingly prominent. In particular, the flowering stage of flowering as a result of spraying nine hundred and twenty, spike stem elongation, coupled with the removal of some functional leaves, nutritional deficiencies significantly, the urgent need for new sources of trace elements to supplement.
