经1973～1974连续两年大田药效与残留分析测定表明,“速灭威”农药在水稻上使用后残效短,残留物少,是一种高效低残留的农药。现将研究初步结果整理如下: 试验设计与分析方法一、田间残留试验设计: 1.水稻不同生育阶段施药后的残留量:试验于1973年早、晚稻。由台州地区农科所,东阳县玉米研究所,平湖县良种场在水稻分蘖、孕穗、齐穗、灌浆等四个不同生育阶段,结合蟓虫的防治用20％“速灭威”粉剂,每亩用量半斤,加水150公斤喷雾一次。于水稻收获时采样分析。
By 1973 ~ 1974 two consecutive years of field efficacy and residue analysis showed that the “quick destroy Wei” pesticide residues in rice after the short, less residue, is a highly efficient pesticide residues. Now the preliminary results of the study are summarized as follows: Experimental design and analysis methods First, the field of residual test design: 1 rice at different stages of fertilization after the application of residues: test in early 1973, late rice. By the Taizhou Regional Agricultural Research Institute, Dongyang Corn Research Institute, Pinghu County, seedling in tillering, booting, full heading, grouting and other four different stages of growth, combined with the prevention and treatment of pinworm with 20% Mu dosage half a catty, add water 150 kg spray once. Sampling at rice harvesting.
