During using anaerobic fermentation slurry as insecticide, there had many problems that are random using, non-strictly prevention and curing time, non-suitable temperature and consistency mixture ratio ctc. In this research, fristly the different mixtures are made according to the different ratio of slurry to additive. Then the insecticidal effects of the mixture are tested in different conditions so as to find the good matches of slurry and additive in laboratory. According to the up result of the good matches extents of mixture, the field experiment is made to test the mixture's insecticidal chraricter and is further found new dosage form which has many good indexes such as good insecticidal effectiveness, little additive dosis ctc. So as to looking for the dosage form's synergism, the significant analysis is done and the characters of the dosages are tested which are ecological and environmental and the new types of dosage are determined. At last, for proving the dosage's field insecticidal potency, the wide field area experiments are done and four new style dosages are triturated which adapt ecological agriculture development. Aadditionally the effective period of the mixtures are tested when other experiments are done.
本文针对厌氧发酵液作为杀虫剂施用时,随用即配和无严格的增效剂种类、喷施时间及温度、浓度配比等现象,首先对各添加剂与厌氧发酵液配成的不同浓度的混和剂在不同条件下进行实验室测试,确定杀虫率高的浓度范围,进一步细化各混和剂浓度范围作田间试验,选出杀虫效果好,添加剂量少等各项指标都好的剂型并进行显著测定,确定出各剂型的增效情况;然后对选出的剂型进行生态和环保特性测定,以便确定新剂型,最后对选定剂型作大区试验来验证田间杀虫药效,最终研制出了4种适合生态农业发展的新型无污染药肥,并对选出的混合剂进行了有效期实验测定。

The article reviews the advanced research on screening sheepbreeds with high resistance against fasciolosis. Screening sheep breeds with high resistance against fasciolosis has been tested by measuring parameter of plasma such as packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin concen tration, glutamate dehydrogenase, gamma glutamyl transferase and aspartate trans ferase and percent take of metacercariae. High resistance of Indonesian thin tail sheep against Fasciola gigantica has been confirmed. The mechanism of high res istance and the time of killing Fasciola gigantica has also been described.
