抛秧田的秧苗偏矮,但具有活棵快、出叶快、分蘖早、群体大、有效穗多、无效分蘖也多、消亡速度慢于手栽秧、成穗率偏低、生育期比手栽秧略短3～5天等特点,因此,在施肥技术上要注意做到扬长避短,以充分发挥抛栽秧苗的生理优势,夺取高产。 抛秧田的施肥方法主要有以下两种方式: (一)“前促、中控、后补”施肥法。即前期重施、早施,中期控氮,后期补氮。这样做的目的,是可以 The seedling throwing seedling is short, but with live trees faster, leaves faster, early tillering, large groups, effective spikes and more ineffective tillers are more, the demise rate slower than the hand-planting seedlings, spike rate is low, the growth period than the hand Sowing slightly shorter 3 to 5 days and other characteristics, therefore, fertilizer technology should pay attention to avoid weaknesses in order to give full play throwing planted seedlings physiological advantages, to obtain high yield. Throwing seedling field fertilization methods are mainly the following two ways: (A) “before the promotion, control, after the fill” fertilization method. Re-implementation of the previous, early Shi, mid-term control of nitrogen, nitrogen late. The purpose of doing so is OK
