Method for killing insets on kaffir lily

Abstract

The invention relates to a method for killing insets on kaffir lily. The method comprises the steps that (1) just hatched nymphs are killed with a 1000-fold to 1500-fold 80 percent dimethyl dichloroviny phosphate emulsion, 1500-fold to 2000-fold 90 percent dipterex crystal, a 1000-fold to 2000-fold 50 percent phoxim emulsifiable concentrate agent, 800-fold to 1000-fold 25 percent phosmet emulsifiable concentrate and the like in a spraying mode; (2) insects older than one year are killed with a 1000-fold to 1500-fold 40 percent omethoate emulsifiable concentrate agent, a 800-fold to 1000-fold 50 percent malathion emulsifiable concentrate agent or a 1000-fold to 1500-fold ethion 50 percent emulsifiable concentrate agent in a spraying mode; (3) for insects in a spawning period, 2500-fold to 3500-fold 30 percent moncrotophos is sprayed to a flowerpot or the ground or a plant. The water retention and cold resisting capacity of the kaffir lily can be enhanced, damage of freeze injuries is relieved, the resilience capacity is improved, the freezing point is lowered, and relieving and recovery functions are performed on plants with middle and light levels of freeze injuries. According to the method, the most suitable pesticide can be selected according to the different growth stages of insects for disinsection, the effect is good, operation is easy, and time and labor are saved.

Description

Technical field [0001] The present invention involves the maintenance method of plants, and specially involves a method of a Clivia. Background technique [0002] Clivia is a perennial herbaceous plant in the genus Clivia of the Department of Stone Harry, with a thick and well -drained acidic soil environment; Clivia has high ornamental value and is a more precious flower variety;Waiting for nutritional elements, but do not like thick fertilizer, too high fertilizer concentration will burn the root leaves, so long -acting organic fertilizer is more conducive to the growth of Clivia. At present, people generally use chemical fertilizers, urea, and large feces when applying fertilizer to Clivia.Wait for the fertilizer to the Clivia, although the effect is good, but the nutrients contained in chemical fertilizers and urea are far from meeting the nutritional needs of Clivia. Because of lack of nutrition, it is easy to cause gentleness to grow slowly, mild weight, poor disease resist...

AI Technical Summary

Problems solved by technology

[0002] Clivia is a perennial herb of the Amaryllidaceae Clivia genus. It likes thick, well-drained acidic soil environment; Clivia has high ornamental value and is a relatively rare flower variety; Clivia needs nitrogen, phosphorus and potassium for growth and other nutrient elements, but do not like thick fertilizers. Excessively high fertilizer concentrations will burn the roots and leaves, so long-acting organic fertilizers are more conducive to the growth of Clivia; at present, when people fertilize Clivia, they generally use chemical fertilizers, urea, and manure and other raw materials to topdress Clivia. Although the effect is good, the nutrients contained in chemical fertilizers and urea are far from meeting the nutritional needs of Clivia. Due to lack of nutrients, it is easy to cause Clivia to grow slowly, light in weight, poor in disease resistance, and poor in color. Prone to various diseases and insect pests
