尤溪县管前调节剂厂研制的穗粒灵Ⅰ号、Ⅱ号是用于促进水稻穗粒生长的新型植物生长调节剂。1991年我们组织在全省10个县进行了3项试验,获得成功。在再生稻上使用,平均增产28.4％;在中晚稻的增产幅度为4.0～7.2％。为了进一步筛选出经济简便有效的剂量和方法,1992年,又对穗粒灵进行了大面积示范试验,为大面积应用提供科学依据。 材料与方法 试验在双季稻上进行,组合汕优63,随机完全区组设计。丛插两粒谷,插植规格为20×17厘米,亩施纯氮10公斤,N:P_2O_5:K_2O=1:0.5:0.7。不同调节剂和不同喷施期两个试验的小区面积均匀为0.03亩,重复3次。其余
Youxi pre-regulator regulator plant developed spike tablets Ling, No. II is used to promote the growth of rice grain spike a new type of plant growth regulator. In 1991, we organized three experiments in 10 counties in the province to achieve success. Used on ratooning rice, the average increase of 28.4%; in late rice yield increase of 4.0 to 7.2%. In order to further screen out the economical and convenient dosage and method, in 1992, a large-area demonstration experiment was conducted on spike granule to provide a scientific basis for large area application. Materials and Methods Experiments were conducted on double cropping rice, combining Shanyou 63 with a randomized complete block design. Plexus inserted two valleys, planting specifications for the 20 × 17 cm, Mushi nitrogen 10 kg, N: P_2O_5: K_2O = 1: 0.5: 0.7. Different regulators and different spraying period of two test cell area of 0.03 acres, repeated three times. the remaining
