Seed treatment method for preventing and treating cucurbita pepo L. seedling rot

Abstract

The invention provides a seed treatment method for preventing and treating cucurbita pepo L. seedling rot and belongs to the technical field of agriculture. The method comprises the steps: firstly sterilizing seeds; then utilizing 14 kinds of traditional Chinese medicinal materials of radix pulsatillae, radix euphorbiae lantu, radix isatidis, folium isatidis, herba portulacae, radix scutellariae, szechwan sida herb, herba scuteliariae barbatae, Tibet lancea herb, osmanthus yunnanensis bark, suchow mosla herb, cleistocalyx operculatus leaf, Chinese tallow leaf and rabdosia eriocalys rhizome to soak the seeds; finally utilizing medicament chitosan oligosaccharide, fulvic acid, uniconazole, ABT rooting powder, propamocarb hydrochloride, glycine betaine, chitosan, pinolene and metalaxyl to perform seed dressing. The method disclosed by the invention can prevent varieties of diseases and insects of the cucurbita pepo L., especially has a very good preventing and effect on cucurbita pepo L. seedling rot, further has effects of resisting adverseness and strengthening seedlings and greatly improves yield and quality of the cucurbita pepo L.; meanwhile, the method delays plant drug resistance generation, reduces use amount and use times of pesticide and reduces agricultural cost; furthermore, pesticide residue amount is extremely low, and environmental friendliness is facilitated.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a seed treatment method for preventing and treating squash seedling rot. Background technique [0002] Zucchini belongs to the annual vine herb of Cucurbitaceae Cucurbita. It is native to southern North America. It was introduced from Europe to China for cultivation in the middle of the 19th century, and is cultivated all over the country. Zucchini is rich in vitamin C, glucose and other nutrients, especially high in calcium content, which has the effects of relieving restlessness and thirst, moistening the lungs and relieving cough, clearing away heat and diuresis, reducing swelling and dissipating stagnation, and can also increase immunity, anti-virus, anti-inflammatory Tumor, promote the secretion of insulin in the human body, prevent and treat diabetes, prevent liver and kidney disease, and enhance the regeneration ability of liver and kidney cells.

Problems solved by technology

[0003] Zucchini seedling rot, also known as root rot and wilting disease, is caused by Fusarium oxysporum and Phytophthora nicotianae. The disease usually presents symptoms during the flowering stage and continues until the seedlings are pulled. The disease causes the plants to wither and die. In severe cases The incidence rate is as high as 70%-90%. This disease has become an important factor restricting the cultivation and development of zucchini. At present, the prevention and treatment of rotten seedling disease is still dominated by chemical pesticides. Due to the high toxicity and high residue of chemical pesticides, and the late spraying period, the pesticide residues in edible zucchini exceed the standard, seriously endangering human health and polluting the environment
