Method for applying pine needles in seedling growing at onion land seedling bed

The invention provides a method for applying pine needles in seedling growing at an onion land seedling bed. The pine needle is ecologically friendly and has no virus source body, so that no disease is caused at the seedling bed. The pine needle has an insect repellent effect and thus plays a certain role in preventing subterranean insects. The pine needle can protect and support the root of the onion seedling to prevent the lodging. The pine needle is capable of keeping the humidity and temperature of the seedling bed. With the pine needles, the impacts on the seedling roots by rainwater or poured water can be reduced, the soil is prevented from being washed away, and the cleaning of the seedling root is kept to prevent disease occurrence. The pine needle has the acidic property and the soil in the seedling bed has the alkaline property, so that the pH value of the soil is adjusted by pine needle coverage. 本发明提供了种葱类陆地苗床育苗中松针的使用方法，松针本身生态环保，无任何病毒源体；不会在苗床引发病害；松针本身具有驱虫作用，它对防治地下害虫有定的作用；松针对葱苗的基部保护和支撑作用，可预防倒伏；松针能保持
