摘要：

为解决现有的固体水稻苗床调理剂在生产应用中存在的与床土拌和花工费时、不容易拌匀施匀等问题，经多年攻关研究，成功开发出可拌种/包衣、播时洒施、播后芽前喷施、立针期喷施的液体水稻苗床调理剂——苗壮丰。产品除N、P2O5、K2O总养分≥210（140-45-25） g/L，有机质含量≥30 g/L，pH值≤6，微量元素≥5.5 g/L (其中Zn≥2.0 )之外，还添加了促进根系发育、提高光合效率、控制养分流失等成分。跟现有产品相比，不仅使用方便、省事省工，且对出苗较为安全，能达到比较好的壮苗效果，根系发达、株高适中、假茎增粗、干物质量增加、秧龄弹性增大。2017年海安试验表明，与空白对照相比，播后芽前喷施苗壮丰的处理白根数增40.5%，株高矮1.98 cm，茎基宽增38.9%，SPAD值增55.1%，百苗干物质量增44.9%。为了更好的使用该新产品，文中最后给出水稻新型苗床调理剂——苗壮丰的使用技术。

Abstract:

Solid rice seedbed conditioner was used frequently in rice seedling raising and it is time-consuming and difficult to mix evenly. In order to solve this problem, we have successfully developed a liquid rice seedbed conditioner - Miaozhuangfeng, which could be used though seed mixing/coating or spraying when sowing or after sowing before bud or seedling standing period. This liquid rice seedbed conditioner contains nutrients of N, P2O5, K2O≥210 （140-45-25） g/L, organic matter content≥30 g/L, pH value≤6, and microelements≥5.5 （including Zn≥2.0） g/L. In addition, some ingredients were also added to promote root system development, improve photosynthetic efficiency and control nutrient loss. Compared with the existing products, it is not only safe for seedling emergence and convenient to use and labor saving, but also efficient to cultivate strong seedlings with developed roots, moderate plant height, thickened cauloid, which could increase dry matter weight and seedling age elasticity. According to the experiment in haian in 2017, compared with the blank control, spraying Miaozhuangfeng before bud after sowing could improve the seedling quality, the number of white roots increased by 40.5%, plant height decreased by 1.98 cm, basal stem width increased by 38.9%, leaf SPAD value increased by 55.1%, and dry matter weight of 100 seedlings increased by 44.9%. Moreover, application technology was put forward in this article for its better use.
