| 1 | Tomato Green Cultivation Technology of Reducing Fertilizer and Pesticide Input and Increasing Fertilizer Efficiency显示文摘According to the technical approach of green production and yield increase pattern,green,pollution-free,quality and efficiency improvement can be achieved by reducing nitrogen,controlling phosphorus and stabilizing potassium,replenishing sulfur,zinc,iron,manganese and boron from the aspects of controlling fertilizer,drug and water.The main measures include combination use of organic and inorganic fertilizer,effective control of the amount of nitrogen and phosphate fertilizer,reduction of the application amount of chemical fertilizers and pesticides,and rational crop rotation to reduce the occurrence of diseases and insect pests,which can improve the yield and quality of tomato. | Yongxun MAO Chun LI Lanxiang MA Yuanjing XU Tao WEI | 2022 | Plant Diseases and Pests2022，13，3： | 0 |
| 2 | Acute toxicity and chromosomal aberration toxicity of insect wax and its policosanol显示文摘An acute toxicity test in Sprague Dawley(SD)rats and a chromosomal aberration toxicity test in Chinese hamster lung(CHL)fibroblasts were conducted to promote the application of insect wax and its policosanol.Results of oral acute toxicity test showed that the LD;values of insect wax and its policosanol were higher than 5000 mg/kg.The rats showed no obvious toxic symptoms and survived,suggesting that these substances were not toxic.The chromosomal aberration rates of the CHL cells incubated with insect wax for 3-6 h under metabolic activation conditions and for 3-6 h and 24 h under non-metabolic activation conditions were lower than 5%.No significant difference was found compared with the negative control group.Also,no significant difference in chromosomal aberration rates was found between each dose group of policosanol under metabolic or non-metabolic activation conditions and the negative control group.Therefore,the chromosomal aberration rates of CHL cells treated with insect wax and its policosanol were negative regardless of metabolic activation conditions.These results indicate the absence of acute toxicity and potential chromosomal aberration in the tested dose range of insect wax and its policosanol. | Jinju Ma Kun Li Wenwen Zhang Liyi Ma Juan Xu Lanxiang Liu Xiaoming Chen Hong Zhang | 2022 | Food Science and Human Wellness2022，11，2： | 0 |
