Technical Field
The invention mainly relates to the technical field of plant fertilizers, in particular to a foliar insecticide-fertilizer and the technical field of preparation and application thereof.
Background
The walnut planting area in south Xinjiang area reaches more than 300 ten thousand mu, and the walnut production becomes the post industry for increasing the income of local farmers. With the annual expansion of walnut planting area, the walnut tree age is increased, the requirements on water and fertilizer management are higher and higher, and walnut diseases are more and more serious, wherein the phenomenon of walnut leaf edge scorching is more and more common, so that leaves are reduced, become yellow, brown, withered, leaked, empty, slightly small and not full, the yield and quality of walnuts are seriously influenced, the commodity rate of diseased plants is only 50% -70%, and huge economic loss is caused, thereby influencing the healthy development of the walnut industry.
After the walnut is infected with leaf margin scorch, the walnut begins to dry from the edge of the leaf, gradually spreads to the main vein of the leaf center, the single leaf at the top of the compound leaf shows the symptom firstly, and the wilting symptom does not occur before the withering. The onset time is mostly 6 months and the onset peak is 7 months to 8 months. The overall symptoms in the field are as follows: sporadic spread of field plants or field-by-field plants; for a single plant, symptoms are shown as the disease of leaves on individual branches and the disease of the whole plant leaves; the disease does not occur or rarely occurs in young trees of less than 3 years in terms of age, the onset of the disease is most common in early bearing walnut trees of more than 5 years, and the onset of the disease is relatively mild in large trees of more than 15 years. Until now, no pathogenic pathogen and no sign of spreading are found, and the disease is preliminarily determined to be a physiological disease. The analysis and summary of the pathogenesis of the physiological disease comprise: freezing damage, nutrient deficiency, weak tree vigor, saline-alkali soil stickiness, unsmooth ventilation and light transmission of orchards, dry hot air, late spring irrigation and Na in leaves+、Cl-Enrichment, etc. However, no pesticide and fertilizer specially aiming at the marginal scorching of the walnut leaves is available in the market at present, and no product capable of providing sufficient nutrients, effectively reducing the incidence rate of marginal scorching and achieving the effects of improving the quality of the walnut and increasing the yield is available in the existing research.
