Pollution-free environment-friendly sunflower cultivation method

Abstract

The invention discloses a pollution-free environment-friendly sunflower cultivation method. The method comprises the steps that sunflower seeds are treated, and the sunflower seeds are taken out about one month before sowing for screening; the seeds are put into tap water, standing is conducted for 3 min, and the seeds floating on the water surface are removed; then salt is added into the water, stirring is conducted, standing is conducted for 3 min, and then the seeds floating on the water surface are removed. The pollution-free environment-friendly sunflower cultivation method has the advantages that the novel sunflower cultivation method solves the problem that in the prior art, seed death often occurs when sunflowers are planted at home, two layers of screening is conducted on the sunflower seeds which are in a germ state, the adaptive capacity of the seeds is improved by soaking the seeds in frozen water and normal temperature water repeatedly, and meanwhile the vitality is improved; naturally rotten leaves or weeds or the like are added in soil, the pH value of the soil is improved, and an environment capable of enabling the sunflowers to grow easily is provided.

[0003] In the prior art to the cultivation method of sunflower, still adopt the method of applying organic fertilizer to the fertilization of sunflower great majority, spray pesticide to sunflower simultaneously, use such method to prevent the diseases and insect pests of sunflower, but such preventive method, make chemical fertilizer and Toxic substances of pesticides remain in the soil, which affects the growth of plants. At the same time, the traditional sunflower pot cultivation method cannot guarantee a high survival rate
