Description
Technical field
The present invention relates to plant nutrition field, be specifically related to the method that a planting fruit-trees uses trace element fertilizer.
Background technology
China is world's apple first big producing country, and apple is also Chinese first main product fruit.According to Food and Argriculture OrganizationFAO (FAO) statistics display, the national apple cultivation total area 2,000,000 hm in 2007
2, ultimate production 2,750 ten thousand tons, cultivated area and output account for 18.7% of the fruit total area and 26.5% of fruit ultimate production respectively, and apple cultivation area, ultimate production, occupancy volume per person all occupy first place in the world.The area and the output that are wherein positioned at two large advantage producing regions of northwest loess plateau and Bohai Rim account for 87% and 89% of the whole nation respectively, and still have the trend of increase.
Not only need the macroelement such as nitrogen, phosphorus, potassium in apple production process, also need the trace elements such as boron, zinc, calcium, magnesium, iron, copper, only when various element ratio is suitable, could mutually play a role well, if ratio is improper, then mutually restrict, affect assimilation effect.In recent years there is inclined nitrogen fertilizer application in apple production, lack the serious problems of trace element, and in these trace elements, the shortage of iron, zinc, boron is then the most serious.During fruit tree boron deficiency, there will be shoot tip meristem suppressed, even withered, dead; The tip of a root extends and stops, and in brown, side root is encrypted, and expands below collar; Young leaves shrinkage, curling chlorosis, petiole is short and thick; Spend little less, pollen granule deformity, vitality is weak, and flower bud comes off, and setting percentage is low.Fruit tree lacks showing as of zinc: plant is short and small, leaf minor malformation, and chlorosis or albefaction between blade arteries and veins, often with irregular blotches; Fruit tree germinates evening in early spring, and caulody or side shoot are rosette-stape, and grow thickly, shortened internodes; Fall leaves gradually from base portion to top, blade is narrow and small, matter is crisp, is called " little leaf disease "; Can occur spike top or sick branch withered phenomenon time serious, flower_bud formation reduces, and spending on sick branch significantly diminishes, and not easily bears fruit, and fruit is little and lopsided.The classical symptom of Chlorosis in Fruit trees is young sprout leaf chlorosis yellowish-whiteization, and vein color is deeper than mesophyll, and look circle is clear, claims " yellowtop "; Chlorosis degree from bottom to top increases the weight of successively, and summer, autumn growth morbidity are more than the spring tip, and sick leaf is many in netted floral leaf clearly, serious yellowish-whiteization, and leaf margin be calcination, withered, comes off ahead of time, formation spike top or bald branch.Above-mentioned three kinds of micro-shortages can produce larger impact, trace element supplement of should adopting an effective measure to apple production, quality.
For control apple tree generation trace element deficiency or unbalance disease, the method for trace element supplement is mainly base and grants the micro-fertilizer of foliage-spray.But some meeting of the ferrous sulfate in being manured into soil be oxidized to insoluble high price iron very soon and lose efficacy, and easily causes soil compaction, and zinc sulfate also can be fixed by Soil Phosphorus acid group, thus causes the utilization ratio of micro-fertilizer lower.The micro-fertilizer of foliage-spray is the method for a kind of effect comparatively obviously and fast trace element supplement, but because of its concentration sprayed lower, need repeatedly to spray, by the interference of weather and the factor such as blade is smooth, add burden to orchard worker.
Root Absorption is the most important approach that plant obtains nutrient, and soil available nutritive element concentration is lower and the poor major cause being k-index and absorbing of movability.Be in the patent of invention of CN 103190235 A at application publication number, disclose a kind of arid hillside field applying fruit trees with fertilizer method, it to underground by insertion plastics tubing, is added the method for composite fertilizer and moisture, can ensure the utilization of liquid manure greater efficiency by plastics tubing.Be in the patent of invention of CN 102396319 A at application publication number, disclose a kind of method of applying fruit trees with fertilizer, increase soil fertility and fruit quality by applying organic manure material, balance fertilizing, waste water integration etc.Although all multi-methods can improve macroelement in fertilizer utilization ratio, but two Big Apple advantage producing regions of northwest loess plateau and Bohai Rim are located in the north, soil is based on alkalescence, and soil water content is lower, still the contact avoiding trace element fertilizer and soil is difficult to, trace element movability is poor, easy to be oxidized fixing, is difficult to the utilising efficiency significantly improving trace element.
Summary of the invention
The object of this invention is to provide the method that a planting fruit-trees uses trace element fertilizer, be intended to by analyzing apple tree in 1 year to the demand rule of trace element, root system is adopted directly to absorb the method be combined with slow controlled release, improve fruit tree to the assimilated efficiency of trace element, especially the iron, boron, the zinc element that comparatively lack effectively is supplemented, the method is simple to operate, and effect is rapid and lasting, is conducive to reducing the expense that orchard worker buys micro-fertilizer.
