Application Of Leaf Fertilizer And Green Control Technology In Grape Planting In Greenhouse

The experiment used two grape varieties,coloring incense and sunset red,as the material,and sprayed Taigu Le titanium fertilizer through the foliar surface,and set the concentration of 3 titanium in 1.43ml/L,lml/L,0.77ml/L,and spray the same amount of water.In contrast,the two grape fruits were harvested at maturity,and the light and characteristics of the foliage and fruit quality were determined.Therefore,it is understood whether the photosynthetic characteristics of grape leaves and the quality of grape fruit are affected and affected after spraying titanium fertilizer.Select the most suitable concentration of sprayed titanium fertilizer.The results are as follows:The intrinsic and extrinsic qualities of the fruit of the coloring and sunset red grapes are enhanced by the influence of titanium fertilizer.The test data showed that the soluble solid content of the colored grape and the red grape fruit reached the maximum value of the experiment at a concentration of 1 ml/L,and the two grape fruit pieces at a concentration of 0.77 ml/L.The hardness reaches a maximum.The photosynthetic characteristics of the coloring and sunset red grape plants are improved under the influence of titanium fertilizer.The test data showed that the chlorophyll a and chlorophyll content of the two grape leaves could reach the highest value in this experiment at 1 ml/L concentration.After spraying 0.77ml/L of titanium fertilizer concentration,the chlorophyll a/b of the two grape leaves showed the highest value in this experiment.Amblyseius cucumeris Oudemans could effectively inhibit the growth of Tetranychus urticae Koch population density.By summarizing the control effect of 60 consecutive days,it was found that the control effect decreased at the fourth survey(40 days after the release of Amblyseius cucumeris Oudemans).This time is just the end of the Amblyseius cucumeris Oudemans life cycle.It is necessary to supplement the Amblyseius cucumeris Oudemans release within 40 days of the first release,which can play a better preventive and control effect.In agriculture,the mixture of matrine and stone sulfur is the most economical,harmful and easy to clean.Using lOg/L mixture of stone sulfur and matrine 1.0ml/L in agricultural production,together with other drugs,can effectively inhibit the reproduction and survival of the common pest in grape production.
