Abstract
The invention belongs to the field of agricultural fertilizer application, and in particular relates to a technology for improving the utilization rate of Zn fertilizers applied to crops. In the agricultural application of Zn fertilizers, after the Zn fertilizers of about 3kg (equivalent to pure Zn) are applied into farmland soil (per hectare) with zinc deficiency, a theoretical concentration of a farmland plowing layer containing low-level available Zn can be improved by 130% to 260% in comparison with an initial concentration of the available Zn in the original soil, and thus the supply capacity of the available Zn in the soil can reach a high level, i.e., the Zn fertilizers can meet the demand of Zn absorption of crops within 3 to 4 years. Therefore, when the Zn fertilizers are applied, only the Zn fertilizers of about 3kg (equivalent to pure Zn) need to be applied to the farmland soil (per hectare) with zinc deficiency at an interval of 3 to 4 years, and the application of the Zn fertilizers each year is not required.
Description
Technical field
The invention belongs to agricultural fertilizer field, proprietary code is A01C.Be specifically related to improve the technology using benefit in zinc fertilizer fertilising.
Background technology
Zinc is one of required trace element of plant, and zinc is with cation Zn
2+form is absorbed by plants, and it the synthesis of growth hormone making remote-effects in object, and the growth hormone content when crop lacks zinc in stem and bud reduces, and growth stays cool, and plant is short and small; Zinc is also the activator of many enzymes simultaneously, by producing wide influence to plant carbon and nitrogen metabolism, therefore contributes to photosynthesis; Zinc also can strengthen the resistance of plant simultaneously, improves kernel weight, changes the ratio of seed and cane;
The metal activation agent of zinc mainly as enzyme in plant corpus is the component of some dehydrases, carbonic anhydrase and zinc lipase, and these enzymes play an important role to the synthesis of the Substance P hydrolysis in plant corpus, redox process and protein; The zinc-containing metal enzyme found the earliest is carbonic anhydrase, and this enzyme is very wide at plant distribution in vivo, is mainly present in chloroplast.The aquation of its catalysis carbonic acid gas, in promotion photosynthesis, carbonic acid gas is fixing, and scarce zinc makes the activity of carbonic anhydrase reduce.Therefore, the formation of zinc to carbohydrate is important.Zinc also participates in the synthesis of growth hormone (heteroauxin) in plant corpus, and when lacking zinc, the growth hormone content in plant corpus decreases, grow and occur dead state, stipes shortens, and plant is short and small, leaf expansion extends and is blocked, and forms leaflet, and in leafage shape; Zinc is the neccessary composition of cytoribosome, participates in chlorophyllous formation; Plant zinc deficiency grows, and stagnation, blade reduce, stipes shortens.
China's zinc deficient soil is more.Zinc deficient soil executes zinc obvious effect of increasing production, and different plants is different to the sensitivity of scarce zinc.Some plants are responsive especially to soil zinc deficiency, can be used as the indicator plant lacking zinc area; The most responsive to zinc with paddy rice, corn in gramineous crop, can be used as the index crop judging the effective Zn content of zinc in soil; In dicotyledon, potato, tomato, beet etc. compare susceptibility to zinc; Perennial fruit tree as oranges and tangerines, grape, peach, apple, etc. also very sensitive to zinc; Light green, yellow or white rust staining is there is, especially on Lao Ye between vein when crop lacks zinc; In field, visible plant height is uneven, and the maturing stage postpones, and fruit development is bad; Report that the plant of scarce zinc has " rice contracting seedling ", " stiff seedling ", " the seat root and stem of certain plants " of paddy rice in China, " little leaf " of the fruit tree such as " white bud ", oranges and tangerines, " bronzed disease " of tung oil tree etc. of corn; Crop dry matter zinc content is generally greater than 20mg/kg, may lack zinc lower than during 20mg/kg.
Full Zn content excursion in soil is very large, and from lower bound to height, the scope of limit is roughly 10-300mg/kg, and average zinc content is 50mg/kg; The full Zn content mean value of Chinese soil is higher than global mean value, is roughly average 100mg/kg; The full Zn content of soil is mainly by the impact of environmental condition in parent soil material and soil-forming process; In general the soil zinc content of basic rock growth is higher than acid rock, the most easily lacks zinc from soil texture sand, because be easy to weathering containing the rock forming mineral of zinc, and forms the thinner soil particle of quality; Due to clay and organic suction-operated, zinc is usually enriched in table soil; When surface soil layer suffers erosion, Zinc content of soil is in reduced levels.
At present to the research of soil and plant zinc mainly concentrate on each Plants to the quantity delivered research of the absorptive amount research of zinc, various Soil Available Zinc, the research of soil zinc deficiency symptom, zinc to the murder by poisoning research of plant, cadmium and the interactive plant effect of cadmium zinc, zinc to fields such as carbonic anhydrase study on the synthesis, the method provided in zinc fertilizer application makes the annual application of zinc fertilizer of base fertilizer once or 2 years once, make seed manure to plant at every turn and use, foliage-spray per season is time-consuming once or several times; This patent is on the basis of analyzing and researching to the testing result of Soil Available Zinc, use in conjunction with zinc fertilizer and from soil, absorbed the total amount of Soil Available Zinc by adsorption by soil every year with crops afterwards, create a kind of agricultural application technology of zinc fertilizer, this technology can improve zinc fertilizer availability in Crops in Applying Fertilizer, saves manpower and zinc fertilizer fertilizer.Through retrieving domestic and international pertinent literature: find no the report with " a kind of agricultural application technology of zinc fertilizer " identical content.
Summary of the invention
When the agricultural fertilizer of zinc fertilizer, lack zinc agricultural land soil per hectare application of zinc fertilizer (amounting to pure Zn) about 3kg, just can make the effective zinc theoretical concentration of medium level agricultural land soil plow layer, zinc initial concentration raising 130 ~ 260% more effective in original agricultural land soil, ensure that the supply capacity of Soil Available Zinc reaches higher level, the effective zinc of zinc fertilizer just can meet the absorption of crop 3-4.Therefore when zinc fertilizer applies fertilizer, lacking zinc agricultural land soil need only every 3-4 per hectare application of zinc fertilizer (amounting to pure Zn) about 3kg, need not all application of zinc fertilizer every year.
Embodiment
According to effective zinc assay method unified at present, all adopt DTPA lixiviate-atomic absorption spectrophotometry or ICP method to measure, with diethylene triamine pentacetic acid (DTPA) (DTPA) for chelating agent, triethanolamine by atomic absorption spectroscopy determination Available Zn content in soil, then contrasts grade scale determination Soil Available Zinc rich scarce as buffer.When executing per hectare using in farmland zinc fertilizer (amounting to pure Zn) 3kg, the effective zinc theoretical concentration of plough horizon just can be made to improve 1.3 mg/kg, just can make the effective zinc theoretical concentration of the farming operation layer of the effective zinc of medium level, improve 130 ~ 260% than original Soil Available Zinc initial concentration, ensure that the supply capacity of Soil Available Zinc reaches the higher level of graded index; And the zinc that plant absorbs from soil calculates according to annual seed and crops straw 30000 kg, about 600g Zn-ef ficiency is taken away for annual from soil, under the prerequisite not calculating the effective zinc supply capacity of soil self, the zinc fertilizer in being manured into soil can meet absorbing of crop 5 years in theory; Therefore in conjunction with soil self zinc-supplying capacity and other effect of natural conditions (as impacts such as soil acidity or alkalinity, the soil organic matter, available phosphorus impact, calcium magnesium), lack zinc agricultural land soil per hectare application of zinc fertilizer (amounting to pure Zn) about 3kg, zinc fertilizer just can meet the absorption of crop 3-4 to zinc; To adopt when zinc fertilizer is used and macroelement fertilizer, particularly nitrogen, potash fertilizer mix to use and does that base fertilizer is disposable to be applied; Need only every 3-4 per hectare using in farmland zinc fertilizer (amounting to pure Zn) about 3kg, need not all application of zinc fertilizer every year.
