A pesticide application method capable of reducing obstacles to continuous cropping of Lilium longya

Abstract

The invention provides a pesticide application method capable of reducing a longya lilium successive cropping obstacle. The pesticide application method comprises the step of spraying the following pesticides: a soil disinfectant, a soil remediation agent, a biocontrol agent, a soil conditioner and ethylicin, wherein the soil conditioner is a sugar alcohol calcium-magnesium fertilizer; the biocontrol agent is a Pseudomonas aeruginosa SU8 fermentation liquor; and the soil remediation agent is a low temperature extraction liquor containing alfalfa meal, aloe powder and soybean meal. The pesticides selected by the invention are beneficial to improving a PH (Potential of Hydrogen) value and nutrient elements of longya lilium successive cropping soil, and reducing the fungal disease of longya lilium, so that the yield and the quality of the lilium are improved. Through a synergistic effect of the pesticides selected by the invention, the aim of reducing the longya lilium successive cropping obstacle can be achieved.

Description

technical field [0001] The invention belongs to the field of crop planting, and in particular relates to a pesticide application method capable of reducing obstacles to continuous cropping of Lilium japonicus. Background technique [0002] Lilium (Lilium spp) is a perennial herbaceous plant with underground bulbs in the Liliaceae family. It is native to the temperate region of eastern Asia. There are about 96 species of Lilium plants in the world, and about half of them are in my country. Among them, 36 species, The 15 lily varieties are endemic to my country and are mainly cultivated as medicinal, edible and ornamental plants. At present, the edible lilies with large cultivation area in my country mainly include Lilium lancifolium, Lilium browniivar.viridulum, Lilium davidii var.unicolor and Lilium davidiiDuch. , as the nutritional components of lily are continuously excavated by researchers, lily has attracted more and more attention from consumers, growers and researchers....

Problems solved by technology

There is also a serious problem of continuous cropping obstacles in Panax notoginseng. Since Panax notoginseng is planted in a large area year after year, and Panax notoginseng is a perennial herbaceous plant, the loss caused by continuous cropping obstacles is as high as 30-40%. In severe cases, the loss can reach more than 70%, or even no harvest.

[0010] Relevant research results show that the continuous cropping obstacle of Lilium longya is caused by a combination of factors, and its mechanism is as follows: ①During the growth of lily, its roots can secrete a variety of organic compounds, making the soil acidic; ②Acidic soil destroys Lily's absorption of soil nutrients inhibits the normal growth of lily. On the other hand, acidic soil is conducive to the growth and reproduction of fungi, which leads to serious fungal diseases during the growth of lily, and seriously affects the yield and quality.

③Planting Longya lily in successive years will continuously acidify the soil and cause obstacles to continuous cropping of lily
