Insect attractant capable of improving pollination rate and fruit set percentage of jujube tree and application of insect attractant

Abstract

The invention particularly discloses an insect attractant capable of improving the pollination rate and the fruit set percentage of a jujube tree, and application of the insect attractant. The insectattractant comprises a nutrient solution and an animal and vegetable decomposition liquid, wherein the nutrient solution comprises the following ingredients by weight percent: 27.56-38.38% of honey, 0.01-0.09% of putrescine, 0.01-0.09% of spermidine, 0.1-1.3% of salicylic acid, 0.1-0.5% of gibberellin and 60.36-71.5% of urea; the animal and vegetable decomposition liquid is a supernate obtained byfiltering after fermentation of egg, cooked beans and chicken entrails for 7-8 days at 25-35 DEG C; and the nutrient solution, the animal and vegetable decomposition liquid and water are compounded at the proportion of 3:1:16. By spraying the insect attractant onto jujube flowers in the flowering stage, the proportion of fly flower-visiting insects in the total flower-visiting insect number is averagely increased by 5-8 percent. The insect attractant can be sprayed to achieve a remarkable trapping effect on flies and bees, the number and the flower-visiting frequency of flower-visiting insects are increased in a unit time, and the pollination and fertilization rates of jujube flowers are increased. After spraying of 100 times and 200 times of the insect attractant, the single-plant yieldsof the jujube tree are increased by 56.94% and 35.08% respectively, the prune single-plant yields are increased b6 36.36% and 25.38% respectively, and the almond single-plant yields are increased by48.11% and 44,30% respectively.

Description

technical field

[0001] The invention relates to the technical field of plant foliage fertilizer, in particular to the technical field of an insect attractant for improving jujube pollination and fruit setting rate and its application. Background technique

[0002] Jujube has high nutritional value and medicinal value, and is deeply loved by domestic consumers. The consumption is increasing. It has become a large fruit tree with an area equivalent to that of apples and citrus, and its output ranks first in dry fruits. In recent years, the output has increased rapidly and the market has continued to expand, and the demand for jujubes is increasing. Jujube jujube trees are more resistant to drought and waterlogging, but higher air humidity is required during the flowering period, otherwise it will be unfavorable for pollination and fruit setting, especially in Xinjiang where the humidity during the flowering period is too low, the temperature changes greatly, and the climate is...
