The Effect Of The Micro-fertilizer And The REEs On The Plant Character And The Physiology And The Yield Of Maize

Using Yedan 13 and Denghai 11 as the test varieties in this research, to search the influence of the huashuo 828 multi-functional nourishing liquid soaking seed and the rare earth elements (REEs) soaking seed on the maize seedling shape characteristic and the physiologyical characteristic of whole breeding time of maize, analyses the impact of the huashuo 828 multi-functional nourishing liquid soaking seed with the REEs soaking seed on two variety spike properties and yield finally. The main results were shown as following:1. Huashuo 828 and the REEs soaking seed have obvious influence on the plant character of the maize , through compare to find Huashuo 828 is more impact on maize seedlings. They are able to improve leaf numbers, leaf long, leaf wide, leaf area , single plant in weight ,and can reduce the height of seedlings , make the maize seedling display the good growth situation. It can infer Huashuo 828 and the REEs soaking can shorten maize seedling of section, can promote the maize leaf cell to divide and extend, benefit the production and accumulation of the organic matter, still there may be function of promoting the seedling root system to grow , thus improve the seedling quality of the maize, form the strong sprout, strengthen the ability of seedlings to resist cold, lay a good foundation for the growth for the future of maize.2. maize seedlings chlorophyll, soluble candy, soluble protein, the whole nitrogen and total protein content show a tendency to increase progressively from 3 leaf stage to 7 leaf stage. Huashuo 828 and the REEs soaking seed can raise the maize seedlings chlorophyll, soluble candy, soluble protein, the whole nitrogen and total protein content. This is mainly because these two kinds of reagent have raised the content of chlorophyll, strengthen the photosynthesis of the maize seedling, produce such organic matters as more carbohydrate, protein, etc, thus the one that improve the seedling is resisted cold.3. The content of chlorophyll, soluble protein and the whole nitrogen and total proteinin maize show unimodal curve in the whole breeding time, leaf soluble candy in maize show bimodal curve in the whole breeding time, it is relatively high before or after twintching tassel stage, form two pieces of peak value. Huashuo 828 and the REEs soaking seed have obvious effects to maize in the different breeding time, can improve maize content of chlorophyll, soluble candy, soluble protein, the whole nitrogen and total protein of leaf at the same time. This is because Huashuo 828 and the REEs soaking seed make maize form the strong sprout after emerging, raise the content of chlorophyll, strengthen the photosynthesis, produce more organic matter, improve seedlings to resist cold, lay a good foundation for the growth for the future. Make the leaf of the maize to delay old and feeble in growing on later stage, strengthen the photosynthesis and intensity of suppression, produce more organic matter, improve and resist against the adversity, and can promote the nutrition of nitrogen in the leaf to shift to the seed.4 Huashuo 828 and the REEs soaking seed can obvious accelerate accumulation of the dry matter weight in the whole breeding stage. The trends of accumulate the dry matter in maize is lower at earlier stage or later stage in generally,but higher in middle period relatively, the relation of plant grow speed and time present model S curve. For each varieties and treatments dry matter accumulate and accumulating speed were greater than contrast each every variety. But the dry matter of Yedan 13 was accumulated by Huashuo 828 soaking seed is smaller than other treatments at later stage. Study indicate, Huashuo 828 and the REEs can strengthen the dry matter to synthetic and accumulation, this is because after Huashuo 828 soaking seed and REEs soaking seed, the maize formed the strong sprout in seedling stage, form good growing situation, establish good foundation for the growth and development of maize afterwards, benefit the maize to accumulate more organic matter in the following growth.5.Huashuo 828 and the REEs soaking seed can obvious can improve maize spike properties obviously, show as high bald and sharp long to reduce than contrast, spike long, spike array numbers and ear number per array increase mainly; the spike kernel in weigh, per one hundred ear in weight and the yield of theory were indicated by analysis of variance, except that Denghai 11 was treated by the REEs, other all of the weight in the spike kernel, the weight per one hundred ear and yield were greater than contrast notably or extremely.
