Preparation method of compound fertilizer for preventing and controlling poinsettia leaf spot

Abstract

The invention discloses a preparation method of a compound fertilizer for preventing and controlling poinsettia leaf spot. The compound fertilizer is prepared from the following raw materials: 50-80 parts of corn cob granule carbon, 10-15 parts of silkworm excrement, 10-16 parts of camellia oil residue, 10 to 14 parts of calcium superphosphate, 14 to 18 parts of urea, 2 to 3 parts of betaine, 3 to7 parts of magnesium oxide, 2 to 4 parts of potassium sulfate, 3 to 5 parts of zinc sulfate, 2 to 5 parts of diammonium phosphate, 6 to 9 parts of dried aboveground part of artemisia annua, 1 to 4 parts of zinc sulfate heptahydrate, 20 to 24 parts of white stone powder, 5 to 9 parts of urea, 1 to 3 parts of cinnamon oil, 10 to 15 parts of activated carbon, 5 to 10 parts of amino acids, 2 to 4 parts of fulvic acid, 4 to 8 parts of tripterygium wilfordii, 10 to 15 parts of Chinese prickly ash, 4 to 8 parts of sulfur, 6 to 8 parts of radix puerariae and 50 to 100 parts of water. The compound fertilizer for preventing and controlling poinsettia leaf spot prepared by the invention not only has the advantages of low cost, high nutritional value, and high utilization rate, and remarkable prevention and control effect on poinsettia leaf spot.

Description

technical field [0001] The invention relates to a preparation method of compound fertilizer for preventing and treating poinsettia leaf spot. technical background [0002] With the rapid development of society and economy, the continuous improvement of people's quality of life and the gradual improvement of the environment, the demand for ornamental plants is growing. my country's flowers and other ornamental plants have a long history and rich heritage, and the people's appreciation level of ornamental plants is also constantly improving, which is very beneficial to expanding the consumption of ornamental plants. Among them, poinsettia, Euphorbiaceae Euphorbia plant, also known as Christmas flower, is a red flower used for decoration at Christmas. Euphorbia is a deciduous erect shrub. The single leaves are alternate, ovate-elliptic to broadly lanceolate, 10-15 cm long, with soft hairs on the back, and narrower leaves (also called bracts) on the top of branches. The flo...

Problems solved by technology

At present, the prevention and control method for the disease is single, generally only by spraying chemical agents to prevent and control, but if used for a long time, the disease is easy to develop resistance, resulting in a decrease in drug efficacy, thereby increasing the amount of pesticides and prolonging the use time, which will lead to Residual pesticides are more harmful to humans and animals, so it is necessary to reduce the application of chemical pesticides and improve the disease resistance of flowers

And the fertilizer of present prior art only has the nutritive function of fertilizer, does not have the generation of controlling flower disease and the effect of damage, therefore urgently needs to optimize fertilizer structure and formula, develops a kind of compound fertilizer of preventing and treating poinsettia leaf spot disease
