Abstract
The invention discloses a foliar spray fertilizer for preventing yellow leaf disease of a pear nursery stock. The foliar fertilizer is prepared by mixing raw materials such as urea, potassium dihydrogen phosphate, ferrous sulfate and magnesium sulfate in a certain ratio. After the foliar fertilizer is used for preventing the yellow leaf disease of the pear nursery stock, leaves normally grow and are thickened, tissues are full, and a root system is developed.
Description
Technical field
The invention belongs to fruit tree disease prevention technical field, be specifically related to a kind of foliar applied fertilizer that prevents pear tree nursery stock yellowtop.
Background technology
Because pear tree produces adventive root difficulty, by the method for group training, be difficult to realize the production of nursery stock, graft seedling growth is still a kind of main method of China pear tree, and the main standard of weighing seedling quality is that the height of nursery stock, rugosity, root system situation and tissue enrich degree.Because birch-leaf pear adaptability is extensive, strong with the avidity of pear tree, in the pear tree of China is grown seedlings, the nursery stock with birch-leaf pear as stock has accounted for more than 70%.And the flourishing growth downwards of birch-leaf pear main root, seldom, seldom, surviving rate is lower for the seedling root of producing for lateral root.For improving the root system quality of pear tree nursery stock, in the eighties in last century, China starts to adopt the nursery new technology of being completely cured, and has effectively increased the lateral root number of nursery stock, and the person of growing seedlings is the overground part quality that realizes nursery stock, also adopted grafting pinching growth-promoting then branch more simultaneously, and enrich macronutrient, and caused therefrom the nutritive props imbalance of nursery stock, make the slightly excessive growth of nursery stock pair inspiring after pinching, yellow leaf, does not organize and enriches.
Summary of the invention
The object of the present invention is to provide a kind of foliar applied fertilizer that prevents pear tree nursery stock yellowtop, this fertilizer recovers the green demand to nutrition according to the physiological reason of pear tree generation yellowtop and blade face, will be big or middle, micronutrient is by proper ratio compatibility, thereby make leaf growth normal, thickening vanes, tissue enriches, well developed root system.
For achieving the above object, the present invention takes following technical scheme:
Prevent a foliar applied fertilizer for pear tree nursery stock yellowtop, the weight ratio of choosing feed composition is urea (18-22), potassium primary phosphate (34-38), ferrous sulfate (38-42), magnesium sulfate (3-4).In fertilizer, the weight ratio of effective ingredient and content is nitrogen (20-23), phosphorus (18-20), potassium (23-25), iron (31-35), magnesium (1-2).Above-mentioned each feed composition fertilizer is mixed, can obtain having the fertilizer of corresponding effective component content.
The present invention compared with prior art, has following advantage:
By the mode of blade face supplementary fertilizer, supplemented nursery stock unbalance in the soil nutrient supply of ramp phase, nutrient content is complete, and nutrient reasonable ratio is used saving of labor, and fertilizer efficiency is fast, and utilization rate of fertilizer is high.
According to this formula, the pear tree nursery stock of being completely cured after pinching is used, can make comparatively rapidly Pears recover normal, the prosperity of nursery stock lateral root can produce the lateral root 3-4 of diameter rugosity more than 0.2cm, increase length and be more than 30cm pair slightly more than 3, tissue enriches, robust growth after seedling planting, surviving rate is high.
Embodiment
The invention provides a kind of foliar applied fertilizer that prevents pear tree nursery stock yellowtop, in described fertilizer according to weight ratio, comprise following component: urea (18-22), potassium primary phosphate (34-38), ferrous sulfate (38-42), magnesium sulfate (3-4), mix each feed composition.In fertilizer, the weight ratio of effective ingredient and content is nitrogen (20-23), phosphorus (18-20), potassium (23-25), iron (31-35), magnesium (1-2).Preferably, in described fertilizer, according to weight ratio, comprise following component: urea (18-20), potassium primary phosphate (34-36), ferrous sulfate (38-40), magnesium sulfate (3-3.3), mix each feed composition.
Can also preferably, choose following raw material weight ratio: urea (20-22), potassium primary phosphate (36-38), ferrous sulfate (40-42), magnesium sulfate (3.3-4), mix each feed composition.
