Embodiment Construction

[0011] In order to make the means, creation features, objectives and effects of the present invention easy to understand, the present invention will be further elaborated below.

[0012] In the process of cultivating chrysanthemums in the greenhouse, when aphids are found, immediately use a mixed solution of 0.3% urea, 0.5% ammonium bicarbonate and 0.3% ammonia to spray the chrysanthemum leaves evenly, spray once every 5 days, continuously Spray 3 times. During the flowering stage of chrysanthemum plants, the survival rate of aphids in the whole plant including flowers was investigated. The survey results show that the nitrogen fertilizer has a control effect of more than 98% on the aphids of the whole chrysanthemum plant, so as to obtain aphid-free chrysanthemum plants.

[0013] The invention obtains an effective method for preventing and controlling the harm of the chrysanthemum aphid by utilizing the nitrogen fertilizer.

Abstract

The invention discloses a method of utilizing nitrogenous fertilizer to prevent and control aphids of chrysanthemums for tea. The method comprises the steps that in the process of cultivating the chrysanthemums in a greenhouse, when the aphids are found out, a mixed solution of a 0.3% urea solution, a 0.5% ammonium hydrogencarbonate solution and a 0.3% ammonia solution is immediately used and sprayed uniformly onto the leaves of the chrysanthemums, wherein the mixed solution is sprayed once every 5 days and sprayed continuously three times. By utilizing the nitrogenous fertilizer solutions fortreatment, the aphid damage prevention and control effect on the whole chrysanthemums reaches 98% and above. The effective method of utilizing the nitrogenous fertilizer to prevent and control the damage caused by the chrysanthemum aphids is obtained, and plants of the chrysanthemums without aphid damage are obtained.

Description

technical field [0001] The invention relates to a method for controlling chrysanthemum (Chrysanthemum morifolium Rmat.) aphids by utilizing nitrogen fertilizer, and belongs to the field of cell biology and biology. Background technique [0002] Chrysanthemum (Chrysanthemum morifolium Rmat.) is one of the top ten traditional flowers in my country and one of the four major cut flowers in the world. The chrysanthemum is colorful and rich in flower patterns, and is very popular among people. Chrysanthemum is mainly used for landscaping, ground cover, interior decoration, tea, medicine and so on. At present, the cultivation area of ​​chrysanthemum is constantly expanding. With the continuous expansion of chrysanthemum cultivation area and the continuous improvement of intensive production, insect damage is becoming more and more serious, seriously affecting the yield and quality of chrysanthemum. Aphids are one of the main pests that harm chrysanthemums. Aphids (Aphidinea) bel...
