目的和方法我院1959年曾用1%的硫酸铵和0.3%的过磷酸钙溶液浸秧根,其效果为:提前返青,增加了产量。又因我省大多数稻田,均以浸种后直接播种,因此进一步探讨幼芽的肥育甚为必要。所以,我们于1960年三月分别以硫酸铵(以后简称硫铵(、硫铵加过磷酸钙(以后简称过石)及硫铵加过石加硫酸钾溶液,肥育水稻幼芽,以观察其对幼苗生长的影响。
Aims and Methods Our hospital in 1959 with 1% ammonium sulfate and 0.3% superphosphate solution soaked roots, the effect is: early green, increase the yield. Because most of the rice fields in our province are sowed directly after soaking, so to further explore the buds of young sprouts is very necessary. Therefore, in March 1960 we used ammonium sulfate (hereinafter referred to as ammonium sulfate (ammonium sulfate plus superphosphate (hereinafter referred to as stone) and ammonium sulfate plus stone plus potassium sulfate solution, fattening rice buds to observe its Effect on seedling growth.
