Helianthus annuus pollution-free environment-friendly type plantation method

Abstract

The invention discloses a Helianthus annuus pollution-free environment-friendly type plantation method comprising the following steps: placing selected Helianthus annuus seeds in brine for 2 hours of immersion under the temperature of 50 DEG C; removing immersed Helianthus annuus seeds and placing same into zinc sulfur phosphor solution for 1 hour immersion; naturally airing the seeds in a ventilation place; placing aired seeds into a nutrient solution prepared in advance, wherein the nutrient solution comprises inorganic nutriment, carbon source, vitamin, growth adjusting substance and organic additive; culturing the Helianthus annuus seeds in a thermostatic chamber with room temperature of 28 DEG C. The advantages are that the Helianthus annuus pollution-free environment-friendly type plantation method can solve the problems that a conventional method uses fertilizers and pesticides for fertilization and insect disease prevention in a long term; the novel method can reduce soil harmful substance to the bottom level, can increase Helianthus annuus survival rate, and can simplify a sowing process.

Description

technical field [0001] The invention relates to the field of sunflower planting methods, in particular to a pollution-free and environment-friendly planting method of sunflowers.

Problems solved by technology

[0003] Most of the fertilization of sunflower still adopts the method of applying organic fertilizer in the planting method of sunflower in the prior art, and sprays pesticide to sunflower simultaneously, uses such method to prevent the damage by disease and insect of sunflower, but such irrigation and preventive method, make The toxic substances of chemical fertilizers and pesticides remain in the soil, which affects the growth of plants. At the same time, the traditional irrigation method wastes a lot of water resources, which is not suitable for the current irrigation concept.
