Insect egg killing composition for soil improvement and application of insect egg killing composition

The invention belongs to the technical field of agriculture and forestry, and discloses an insect egg killing composition for soil improvement and application of the insect egg killing composition. The composition comprises the following components in parts by weight: 500-2000 parts of macleaya cordata and 10-35 parts of calcium hydroxide. The composition has an excellent insect egg killing effect, the ovum killing rate can reach 90% or above and is greater than the sum of the ovum killing rate of macleaya cordata and the ovum killing rate of calcium hydroxide, the synergistic interaction effect is achieved, and meanwhile the composition is safe, nontoxic and free of pollution to the environment. The composition can be used for pest control and under-forest flower scene construction. 本发明属于农林技术领域，公开了一种用于土壤改良的灭虫卵组合物及其应用。该组合物包含以下重量份的组分：博落回500～2000份、氢氧化钙10～35份。该组合物具有优异的杀虫卵效果，杀虫卵率能达到90％以上，大于博落回的杀虫卵率和氢氧化钙的杀虫卵率之和，具有协同增效的作用，同时，该组合物安全无毒，不会对环境造成污染。该组合物可用于害虫防治和林下花景构建。
