机械化插秧技术因插秧机是采用切土块原理完成分秧动作,要求每土块上种子数相当,且90%以上要成苗,因此对种子发芽率及播种均匀度、床土有严格的要求。床土应取杂草、病菌少,轻粘性土壤,最好是冬天取用晒垡后的土,pH值4.5～7之间,土壤经粉碎过筛拌肥后使用。种子应选用发芽率95%以上,发芽势85%以上优质稻种,经翻晒除芒、盐水选种、浸种消毒、催芽至露白。用硬盘在播种流水线上完成铺底土(2厘米)、淋水、播种、覆土(0.5厘米)
Mechanized transplanting technology because the transplanter is the use of cutting block principle to complete sub-seedling action, requires that the number of seeds per parcel quite, and more than 90% to seedlings, so the seed germination rate and sowing uniformity, bed soil have strict requirements . Bed soil should be weeds, less germs, lightly sticky soil, it is best to take winter drying sun, pH 4.5 to 7 between the soil after smashing sieve mixed with fertilizer. Seeds should be used more than 95% germination rate, germination potential of more than 85% of high-quality rice species, in addition to drying through the sun, salt selection, soaking germicide, germination to dew white. With the hard disk in the sowing line to complete the subsoil (2 cm), watering, sowing, casing (0.5 cm)
