早稻丸粒化育秧技术试验报告

THE EXPERIMENTAL REPORT ON THE PELLETIZING SEEDLING RAISING OF EARLY RICE

早稻丸粒化育秧技术,是选用方便廉价的保温性和防病、杀菌、助长的药剂及适量的肥料作为配制丸粒的主要原料,使之具有良好的保温、抗寒、杀菌和促进秧苗健壮生长的作用.其技术关键在于掌握配料中的肥料要适量,控制在30%～40%。丸粒化育秧技术的效果效益是肯定的,它操作简便易行,适合长江流域稻区千家万户农民应用,育秧成本低,秧苗素质好,单株叶数多0.3～0.5片,白根多10%以上,苗病少17%～25%,结实率2%～4%,单产增长1成以上,成秧率高20%～30%,均比薄地膜育秧优胜,经微机检测达到了显著或极显著水平。并且每推广0.067 ha 丸粒化秧比薄地膜育秧降低成本79元左右,加上增产因素(1 ha 栽8 ha本田),可增加纯收益285.91～446.66元,经济、社会效益显著,有广泛的应用价值和推广前景。

The pelletizing seedling raising of early rice is a technique of raising early rice seedlings by means of wrapping the rice seeds with a coat of conveniently available and low-price chemicals or pesticides with function of preserving heat,killing bacteria and helping devel- opment together with proper amount of fertilizer,in other words,compounding the seeds with other materials into pellets.The materials should perform the function of heal preser- vation,cold resistance,bacterium killing and development promotion.The key of the tech- nique is the proper selection of pesticides,in the compound,which should be dead on the target.And the fertilizer should also be appropriate.The results of a few years' experiments show that the seedlings raised with this technique are of good quality,more leaves per plant,high seedling rate,fewer diseased plants.In short,this technique is worthy of wide practical application.
