Reference examples uses general planting technology to carry out maize planting.
Comparative test:
1) portable chlorophyll meter (SPAD-502) is utilized to measure the content of corn growth stage blade SPAD in each embodiment；
Measure soil moisture content.
2) corn growth stage ground biomass, milpa stem cross-sectional area and Underground roots biomass are measured；
3), after gathering, measure that corn yield, fringe be thick respectively, spike length, row grain number, grain number per spike and mass of 1000 kernel, result is as follows
Table:
As can be seen from the table, nitrogenous fertilizer is the critical nutrients factor affecting corn yield height, the corn yield of four embodiments
Relatively compare and increase by 35%, 51%, 69% and 62% respectively.Along with nitrogen fertilizer amount increases, corn yield increases, but amount of nitrogenous fertilizer reaches
To 360kg ha-1Time, corn yield does not increase, and illustrates that excess applied nitrogen not necessarily can increase yield.Nitrogenous fertilizer is used
Amount appreciable impact corn yield may be by what the change of the character such as fringe thick, spike length, the row grain number of Semen Maydis was worked.
Fig. 1 shows that evening based on Rhizosphere of Crops nitrogenous fertilizer metabolism of the present invention receives maize growth in each embodiment of implantation methods
Phase leaf chlorophyll SPAD value and the contrast trend of soil moisture content.Corn growth stage embodiment 1, embodiment 2, real
Execute example 3 and embodiment 4 increases by 5%, 8%, 11% and 13% than reference examples respectively.Corn growth stage soil moisture content is being weaved silk
Phase is preferably minimized value.
Fig. 2 shows corn growth stage ground biomass (A) of the present invention and Underground roots biomass (B) variation tendency, with
Comparison is compared, and four embodiments process period of maturation the upperground part biomass meansigma methods increases by 59%.Underground root system in five embodiments
Biomass reaches maximum in the phase of weaving silk.Corn stem Biomass and root biomass are all in increasing trend, and reach in the period of maturation
To maximum, the stem stalk Biomass wherein compareed is consistently less than other four embodiments.The blade that corn growth stage five processes
Biomass variety feature is different, and compared with the control, period of maturation the upperground part biomass of four embodiments adds about 80%.
Fig. 3 shows and receives in implantation methods Semen Maydis in different embodiments evening based on Rhizosphere of Crops nitrogenous fertilizer metabolism of the present invention
Section of three stem cross-sectional area comparison diagram, as can be seen from the figure nitrogen fertilizer amount appreciable impact milpa stem cross-sectional area on the ground,
