Pure potassium 1.5kg is applied.
As a result of above-mentioned technical proposal, the present invention has the effect that compared with prior art:
The present invention adopts Formula fertilization by soil testing maize planting, by balance fertilizing, reduces applying quantity of chemical fertilizer, improves fertilizer
Material utilization rate, and by the growth phase rational application of fertilizer of corn, maize planting yield reaches 418.2kg/ mus, and economic benefit is obtained
Increase substantially.
Specific embodiment
With reference to specific embodiment, the invention will be further described:
A kind of corn soil testing and formulated fertilization method, comprises the following steps that:
A, soil nutrient detection:It is chad soil for trying plot soil property, topsoil thickness 20cm, the earth sample detection that fetches earth is contained by it
Nutrient is:Organic matter 15.609g/kg, pH value 4.8, full nitrogen 0.958g/kg, available phosphorus 37.2mg/kg, available potassium 24mg/kg;
B, fertilizer formula are formulated:According to pedotheque nutrient testing result and the related soil criteria for classifying, the plot soil is determined
Fertility, with reference to corn field fertilizer efficiency, determines target output for 400kg/ mus, with reference to the nutrient that corn growth needs, then
Calculate and determine fertilizer formula, per mu is applied completely nitrogen, phosphorus, the common 24.8kg of potash fertilizer scale, and nitrogen, phosphorus, potassium press scale 12.8:6:6 are carried out
With applying;
Corn field fertilizer efficiency is as follows:
1st, corn " 3414 " fertilizer efficiency plot experiment, tests kind:Corn honest 619, average annual output:320kg or so/mu.It is used
Fertilizer:Nitrogenous fertilizer is the urea of rivers and ponds nitrogen fertilizer plant production, containing purity nitrogen(N)46%;Phosphate fertilizer is the calcium and magnesium phosphorus of Fuquan, Guizhou phosphate fertilizer plant production
Fertilizer, it is phosphorous(P2O5)12%;Potash fertilizer is Canadian potassium chloride, containing potassium(K2O)60%.
2nd, test method
Using " 3414 " optimized regression design scheme, that is, refer to nitrogen, phosphorus, 3 factors of potassium, 4 levels, 14 process, it is specific as follows
Table 1, table 2:0 level refers to and do not apply fertilizer;2 levels refer to the approximation of local optimum fertilizing amount;1 level=2 level × 0.5;3 level=2
Level × 1.5(For excessive fertilization level).Experimental plot area 36m2 (12m×3m), 14 process, 3 repetitions, using random
Arrangement.
3708~3800 caves of corn planting density/mu(Line-spacing 60cm, spacing in the rows 30cm).Term Fertilization:According to weather reality
Situation, the 100% of phosphate fertilizer and 40% deep placement of the 50% of potash fertilizer, nitrogenous fertilizer make base manure, 60% nitrogenous fertilizer, 50% potash fertilizer carry seedling and attack luxuriant fertilizer.
3rd, test result analysis
Can be seen that from yield sequencing table 3, this test process 6(N2P2K2)Yield be per mu yield 418.2kg, space management(N0P0K0)Produce
Amount is minimum, and per mu yield is 182.3kg, and its yield is processed for 6(N2P2K2)The 43.59% of yield.Illustrate sheet experimental field in soil fertility level
Etc. low.
From fertilizer effect table 4 as can be seen that nitrogen stress area yield accounts for process 6(N2P2K2)Produce in 52.68%, the Que Lin areas of yield
Amount accounts for the 57.03% of optimal fertilization area yield, and potassium deficiency area yield accounts for the 60.02% of optimal fertilization area yield, illustrates this experimental field
