Interpretation of result:
1. different treatment is to the influence of carnation output and economical character
Table 1 shows that the slow release fertilizer of using the embodiment of the invention 1 interpolation additive can improve the Other Main Agronomic Characters of carnation, improves carnation individual plant number of flowers.Though slow-release fertilizer is handled down carnation spray length and freshness date and is compared with common fertilizer processing (Conv-F, Opt-F) with fertilizer treatment not and do not have significant difference, can increase the individual plant number of flowers of carnation.The individual plant number of flowers is the important factor of carnation output.Under the test conditions, what individual plant bud output was the highest is Opt-F-7 ‰ processing, and mean value is 3.6/strain, Opt-F-8 ‰ takes second place, CK individual plant bud output is minimum, is 3.1/strain, and the carnation individual plant number of flowers of using slow release fertilizer has on average increased the 0.3-0.5 branch than CK.
The individual plant number of flowers is to weigh the whether important indicator of high yield of carnation.Under the test conditions, using slow-release fertilizer carnation output all extremely significantly increases (table 1).Fertilizer treatment (2,3,4,5,6) is fertilizer treatment (CK) more not, and yield increasing effect is all arranged, and amount of increase in production is 1.69%-22.88%, and volume variance all reached conspicuous level (table 1) between each was handled.Illustrate and add the required nutrient of growth that the mixed slow-release fertilizer applied once of additive can satisfy the Chinese rose plant influential to Chinese rose each of supply because the nutrient releasing speed difference of slow-release fertilizer breeding time, and cause each handle between output difference to some extent; Compare (3 processing fertilizer nutrient input amounts that Opt-F handled and used slow-release fertilizer equate, all are lower than Conv-F) with the Conv-F processing, Opt-F handles and uses the slow release fertilizer amount of increase in production and reaches 18.33%-20.83%, reaches significantly or utmost point significant difference level.Output just is followed successively by Opt-F-7 ‰＞Opt-F-8 ‰＞Opt-F-9 ‰＞Opt＞Conv-F.As seen, along with the increase of fertilizer input amount, the output of crop but reduces, and this is consistent with law of diminishing return, illustrates, Conv-F does not meet economic fertilization; With wait the NPK ratio to handle to compare with equal nutrient content, slow-release fertilizer (handling 4,5,6) still increases production 0.28%-2.11%, obvious difference between the output.
Table 1 different fertilization is to the influence of carnation output and economical character
Annotate: different upper and lower case letters represent that respectively difference reaches 5% and 1% remarkable water in the same column.
This shows, when using slow-release fertilizer and can effectively save fertilizer and drop into, can significantly improve the output of crop.Result of study of this test and Zhang Fabao etc.
[23]With Zhang Yushu etc.
[24]The research conclusion basically identical.
2. different fertilization is to the influence and the environmental protection effect thereof of carnation this season plant recovery of nutrient
There are notable difference in carnation nitrogen, phosphorus and potassium utilization ratio under the different treatment because of Fertilization Level is different.Under this test conditions, the plant recovery of nutrient that slow release fertilizer is handled is all handled high (seeing Table 2) than common fertilizer (Conv-F and Opt-F).Height with regard to the nutrient input amount is compared, and Conv-F handles N, P
2O
5, K
2Every mu of amount of application of O is respectively 36kg, 24kg, 39kg; Slow-release fertilizer is treated to 30kg, 21kg, 27kg.The two compares, and slow-release fertilizer is handled the plain every mu of amount of application of nitrogen (N) and reduced 6kg, reduces by 16.67% relatively; Phosphorus (P
2O
5) plain every mu of amount of application minimizing 3kg, reduce by 12.5%; And potassium (K
2O) plain every mu of amount of application reduces 12kg, reduces by 30.77%.This season utilization ratio that Conv-F handles azophoska all is starkly lower than other processing, the utilization ratio of N, P and K just is followed successively by Opt-F-7 ‰＞Opt-F-8 ‰＞Opt-F-9 ‰＞Opt-F＞Conv-F, it is the most remarkable that wherein Opt-F-7 ‰ handles its plant recovery of nutrient raising, and this season utilization ratio of nitrogen, phosphorus and potassium has improved 13.88,8.57 and 30.14 percentage points respectively than Conv-F.As seen, along with the increase of fertilizer input amount, the output of crop also reduces (table 1), and its plant recovery of nutrient also reduces greatly, and this is consistent with law of diminishing return, does not meet economic fertilization.
Just wait the NPK ratio and wait the nutrient input amount to compare, the nutrient input amount of Opt-F and Opt-F-7 ‰, Opt-F-8 ‰ and Opt-F-9 ‰ equates, yet the plant recovery of nutrient of using 3 processing of slow release fertilizer is all handled apparently higher than Opt-F, the this season utilization ratio that slow-release fertilizer is handled nitrogen has improved 1.04-3.87 percentage point than the Opt-F processing, phosphorus has improved 1.8-3.77 percentage point, and potassium has improved 5.05-10.23 percentage point.It is the most remarkable that wherein Opt-F-7 ‰ handles nitrogen, phosphorus and the raising of potassium nutrition utilization ratio, handles than Opt-F and improved 3.87,3.77 and 0.23 percentage points respectively.Song Fupeng etc. studies show that under identical amount of nitrogen condition, controlled release nitrogenous fertilizer is handled than common nitrogenous fertilizer and handled 10.1-29.7 percentage point of nitrogen utilization efficiency raising; The holy elder generation of Zheng etc.
[9]Utilize differential technique and tracer study to show, the nitrogen utilization efficiency ratio of slow-release fertilizer is used urea and is improved 37.5 and 32.2 percentage points respectively.The result of study of these results and test is used the conclusion basically identical that slow release fertilizer can effectively improve utilization rate of fertilizer.
Illustrate that slow release fertilizer can effectively regulate the nutrient dissolution rate, the release of nitrogen phosphorus potassium and the absorbing rule of carnation are identical substantially.Do that base manure is disposable to apply, its utilization ratio is higher than common fertilising, reduces the loss of corresponding nitrogen phosphorus potassium, improves utilization rate of fertilizer.As seen, use slow-release fertilizer, be controlled because nutrient discharges, loss approach such as the volatilization of nutrient, leaching are suppressed, and npk nutrient discharges supply to be exceeded in earlier stage, and the later stage has no lack of, and has the effect of " peak load shifting "
[26], more approaching with the nutrient demand curve of crop, reach running balance preferably, not only favourable to crop, and can significantly reduce pollution.
Studies have shown that in a large number utilization rate of fertilizer is low and cause the waste of earth Nonrenewable resources and the deterioration of environment for human survival, become the outstanding problem of influence agricultural and environment sustainable development.The chemical fertilizer rate of fertilizer application constantly increases and irrational using, and has caused pollution of area source such as water pollution and eutrophication, and the element that wherein plays a crucial role is nitrogen and phosphorus
[27]This experimental study is the result show; being accustomed to split application with peasant household handles relatively; on the basis that carnation output significantly increases; use slow-release fertilizer and can reduce nitrogen and the plain consumption of phosphorus significantly; improve utilization rate of fertilizer, the protection of ecotope and the Sustainable development of promotion agricultural are had important practical significance.
