1.1 experimental field basic conditions
Test site is in field experiment base, Shandong Province, be positioned at the southeast, the North China Plain, belong to the moistening monsoon climate in warm temperate zone half, parent soil material is the Yellow River alluvial deposit, soil type is moisture soil, the light earth of topsoil quality, foundation soil fertility index is organic 10.50g/kg, available nitrogen 53.5mg/kg, rapid available phosphorus (P2O5) 14.6mg/kg, available potassium (K2O) 70mg/kg, belong to medium higher fertile soil, in one's respective area, tool is broadly representative.
1.2 test design and enforcement
Test the Chemical Mixed Fertilizer that fertilizer used is obtained by embodiment 1, embodiment 2 and embodiment 3, N-P-K content is 30-11-10,30-10-10,31-11-9, respectively not apply fertilizer and to contrast with the 28-14-10 composite fertilizer that market is sold, the disposable base fertilizer experiment of arrangement summer corn.Following 4 process are set, repeat 3 times, plot area 5 × 5=25m
2, random district group arranges.Test corn variety is the line-spacing plantations such as No. 958, Zheng Dan, 60cm, in sowing on June 20th, 2010, and mu planting density 4500 strain.Experimental field front stubble is winter wheat, sows, do not use base manure after harvesting wheat after removing wheat stalk, rotary tillage soil-working.Each process test fertilizer topdresses in the ranks according to test design in summer corn large mouth (9 leaf stretching period) disposable trench digging in early stage, various management measures is consistent, according to corn different growing, the birth index such as plant height, leaf area respectively, ripening stage results are surveyed and are produced.Process is set to:
2. without fertile contrast;
2. common bulk blended fertilizer contrast: the common bulk blended fertilizer of 28-14-10, mu executes 40 kilograms;
3. embodiment 1:30-11-10BB fertilizer 100%: mu is executed 40 kilograms (1500 grams, every communities);
4. embodiment 2:30-10-10BB fertilizer 100%: mu is executed 40 kilograms (1500 grams, every communities);
5. embodiment 3:31-11-9BB fertilizer 100%: mu is executed 40 kilograms (1500 grams, every communities);
Experimental plot area 5 × 5=25m
2, repeat 3 times, random district group arranges.Each process test fertilizer adopts base manure single fertilization, evenly spreads fertilizer over the fields rotary tillage soil-working behind earth's surface, each community prior to seeding, then sows summer corn.Test corn variety is the line-spacing plantations such as No. 958, Zheng Dan, 60cm, in sowing on June 20th, 2010, and mu planting density 4500 strain.No longer topdress during corn growth, various management measures is consistent, and according to corn different growing, the birth index such as plant height, leaf area respectively, ripening stage results are surveyed and produced.Arrange as shown in Figure 1 between experimental plot.
2. Different Fertilization yield of Summer Corn
Test on October 6th, 2010 corn is ripe, and 8 row are planted in every community, removes limit, both sides row, 5 row results in the middle of selecting, departs from, air-dryly to weigh, and calculates each process maize grain yield in table 1.The results of analysis of variance shows, F=54.412**, P=0.0001 between process, and difference reaches extremely remarkable; Duncan multiple comparisons is then found out further, and each fertilizer treatment is all increased production compared with without fertile contrast, and difference reaches pole conspicuous level, illustrates that imposing different quantities two kinds of bulk blended fertilizers all has vital role to corn yield increasing.Under 100% rate of fertilizer application condition, embodiment 1:30-11-10BB fertilizer; Embodiment 2:30-10-10BB fertilizer; Embodiment 3:31-11-9BB fertilizer; Compared with commercially available 28-14-10 compound manure corn yield, there is obvious effect of increasing production, but all do not reach significance of difference level between three process.
Table 1. different treatment summer corn grain yield result (kg/ mu)
This field test is the single cropping test carried out on the medium higher soil of soil fertility, and the effect of increasing production of fertilizer not necessarily can fully reflect.Add test location and be subject to extreme weather conditions impact not seen once in a hundred years, corn growth Seasonal rainfall amount reaches 592mm, for 2 ~ 3 times of the normal time, long-term wet weather causes illumination, accumulated temperature is not enough, the general underproduction of corn, also produce a very large impact test, overall effect of increasing production is still close to expection.Also embody composite fertilizer of the present invention to the resistance improving corn, opposing natural disaster aspect has good effect simultaneously.
The above is not limitation of the present invention; be noted that for those skilled in the art; under the prerequisite not departing from essential scope of the present invention; can also make some changes, remodeling, interpolation or replacement, these improvements and modifications also should be considered as protection scope of the present invention.
