Embodiment 1
[0024] The embodiment of the present invention provides a kind of biological control method of betel nut yellow disease, comprising the following steps:
[0025] S1. Carry out seedling cultivation after the betel nut seeds are germinated. During the seedling cultivation, every 15 days per plant is used to spray and irrigate with nutrient solution. The nutrient solution includes the following raw materials by weight: 20 parts of nitrogen, phosphorus and potassium compound fertilizer, 10 parts of superphosphate, 2 20 parts of % citric acid solution, 2 parts of enzyme, 90 parts of water, strengthen water and nutrient supply support, and enhance the seedling raising effect;
[0026] S2. After irrigating with nutrient solution, use fungicide to irrigate the roots of each plant every 15 days, and use nutrient powder to fertilize on the 10th day after applying the fungicide, and use it continuously until the root system grows more than 70cm, and the root system grows more than 70cm. ...
Embodiment 2
[0038] The embodiment of the present invention provides a kind of biological control method of betel nut yellow disease, comprising the following steps:
[0039] S1. Carry out seedling cultivation after the betel nut seeds are germinated. During the seedling cultivation, every 15 days per plant application adopts nutrient solution to spray and irrigate. The nutrient solution includes the following raw materials by weight: 10 parts of nitrogen, phosphorus and potassium compound fertilizer, 8 parts of superphosphate, 2 10 parts of % citric acid solution, 1 part of enzyme, 70 parts of water, strengthen water and nutrient supply support, and enhance seedling raising effect;
[0040] S2. After irrigating with nutrient solution, use fungicide to irrigate the roots of each plant every 15 days, and use nutrient powder to fertilize on the 7th day after applying the fungicide, and use it continuously until the root system grows more than 70cm, and the root system grows more than 70cm.

Abstract
The invention provides a biological treatment method for areca nut yellows, and relates to the technical field of plant disease control. The biological treatment method comprises the following steps that S1, areca nut seeds are subjected to seedling raising after germination accelerating, and during seedling raising, a nutrient solution is applied to each plant for spraying irrigation every 15 days; S2, after the nutrient solution is adopted for irrigation, a degerming agent is adopted for root irrigation of each plant every 15 days, nutrition powder is used for fertilization every 7-10 days after the degerming agent is applied, and the nutrition powder is continuously used till the root system grows to 70 cm or above; and S3, during planting, 30 cm trenches are dug around the crown of each areca nut every three months, a compound fertilizer is applied, soil covering after fertilization is completed, and the degerming agent is sprayed once every half a year. By enhancing moisture and nutrient supply support, the seedling raising effect is enhanced, disease occurrence is effectively inhibited, the incidence rate of yellows is remarkably reduced, fruiting of areca nuts is promoted, the annual yield of the areca nuts is improved, and the problem that the yield of the areca nuts is low due to high incidence rate of yellows is solved.
Description
technical field [0001] The invention relates to the technical field of plant disease prevention and control, in particular to a biological treatment method for betel nut yellowing disease. Background technique [0002] Betel nut (scientific name: Areca catechu L.), is an evergreen tree of monocotyledonous plants, primary order, palmaceae, betel nut, with erect stems, tree-like, more than 10 meters high, up to 30 meters high, with obvious ring-shaped leaves Scar, monoecious, multi-branched inflorescence, oblong ovary, oblong or ovoid fruit, ovoid seed, flower and fruit period from March to April, betel nut is native to Malaysia, and China is mainly distributed in Yunnan, Hainan and other regions It is widely cultivated in tropical areas such as Taiwan and tropical Asia. Betel nut is an important Chinese herbal medicine. Some ethnic minorities in the south still use the fruit as a chewing hobby. Betel nut yellowing disease is a plant disease that harms betel nuts. It shows tw...
