于1982-1983年,在印度泰米尔纳德农业大学进行田间试验,以研究施氮和杀虫剂(呋喃丹和甲拌磷)之间的交互作用对水稻生长和产量的影响,并比较这些杀虫剂的植物毒性作用,为水稻生产确定有效而经济的氮肥与土施杀虫剂组合。试验在三个季节重复进行。呋喃丹和甲拌磷能提高水稻根系干重、地上部分干重、叶面积指数、氮吸收量、施用氮素的吸收率、产量构成因素和稻谷产量,施氮量达90kg/ha对上述特性也有类似的影响,杀虫剂与氮肥结合施用可使水稻对氮的需求量减少30kg/ha。从产量来看,最高的配合效果出现在夏季,且呋喃丹和甲拌磷的影响基本相似,对水稻生产来说,氮杀虫剂的最佳组合是60kgN/ha_0.75kg/ha呋喃丹或1.0kg/ha甲拌磷。
In 1982-1983, a field experiment was conducted at the Tamil Nadu Agricultural University in India to study the effects of nitrogen application and interactions between pesticides (carbofuran and phorate) on rice growth and yield, and to compare these Phytotoxic effects of insecticides for the production of rice to determine the effective and economical combination of nitrogen and soil pesticides. The test is repeated in three seasons. Carbofuran and phorate could increase dry weight, dry weight of above-ground parts, leaf area index, nitrogen uptake, nitrogen uptake, yield components and rice yield with nitrogen up to 90 kg / ha. There is also a similar effect. The combination of insecticide and nitrogen fertilizer can reduce the nitrogen demand of rice by 30kg / ha. From the yield point of view, the highest with summer effects, and carbofuran and phorate the impact is basically the same, for rice production, the best combination of nitrogen insecticides is 60kgN / ha_0.75kg / ha carbofuran or 1.0kg / ha phorate.
