Effect Of Selenium Ore Powder On Rice, Honeysuckle And Three Vegetables In Selenium Accumulation

Selenium is a microelement of biological beneficial. Distribution of selenium is rare and the content of selenium in the interior of the earth is 13 μg/g higher than the natural abundance of 0.08 μg/g. Selenium shows zonal distribution in the crust on some degree. There are more than 40 countries and regions of the world lacking of selenium and lacking selenium population has reached 1.5 × 109. Productions abundant of selenium were sold better in the international market. China is rich in selenium resources and the industrial reserves takes the forth place in the world next to Canada, the United States and Belgium, but the distribution is very uneven.71.2% of the industrial reserves distributed in the middle South and the Northwest in China. Selenium lack was common in 2/3 areas in China, from the northeast to the northwest, southwest owned 15 provinces (autonomous regions) of more than 300 counties (cities) forming a narrow strip of selenium lacking region. There are selenium lacking area in regions which are rich in selenium as a result of the limitation and the imbalance of selenium making the Se enriching technology very significant. The research in the selenium content of crops in soil with different selenium content made the foundation for the utilization of selenium. Jiangxi is the main rice producing area in China and of great value for the use of development of Se enriching technology in rice.Experiments which aimed at researching the selenium accumulation cultivation technique of rice, cucumber, eggplant, bitter gourd and the effects on the next seasons’ crops by selenium-rich soil and non-selenium-rich soil were carried out in wan-you vegetable field which was located in fengcheng, jiangxi. Experiments in the effects of selenium mineral fertilizer through different application distances and quantities on honeysuckle and the next seasons’crops were carried out in zibo, shandong. Results were below:Different soil showed significant impacts on early rice effective panicle, setting rate, thousand grains weight, yield and very great significant impacts on number of filled grain. Average panicle (187.7thousands panicles/667m2) of selenium-rich soil treatments was significantly lower than the average panicle (196.3thousands panicles/667m2) of non-selenium-rich soil treatments; Average number of filled grains per panicle(94.90/panicle) in selenium-rich soil is significantly higher than average number of filled grain per panicle (88.76/panicle) in non-selenium-rich solid and average setting rate (82.76%) was significantly higher than the average setting rate (80.74%) in non-selenium-rich soil; Average thousand seeds weight (27.50g) of selenium-rich soil treatment was significantly higher than the average thousand seeds weight (27.40g) of non-selenium-rich soil treatment; Average yield (482.05 Kg/667m-) of selenium-rich soil treatments was significantly higher than the average yield (453.37 Kg/667m2) of non-selenium-rich soil treatments. That is to say, effective panicle of early rice reduced while filled grains per panicle, setting rate, thousand seeds weight and yield increased with the increase of the selenium content of soil.The application of selenium mineral fertilizer impacted effective panicle, filled grains per panicle, setting rate, thousand seeds weight and yield of early rice very significantly. The effective panicle was very significantly different from the other treatments and reached the highest level in treatment B1 with 200.6 thousands/667m2; The filled grains per panicle, setting rate, thousand seeds weight and yield were very significantly different from the other treatments and reached the lowest level in treatment B1 with 85.38 per panicle,74.63%,26.72g and 441.43kg/667 m2, respectively. In other word, the application of selenium mineral fertilizer reduced the effective panicle, but increased the setting rate, thousand seeds weight and total output.Different soil conditions had insignificant effects on panicle, significant effects on thousand seeds weight and yield and affected filled grains per panicle and setting rate of late rice very significantly. Selenium in soil had insignificant effect on the effective panicle on one hand. On the other hand, filled grain, setting rate, thousand grains weight and yield of the selenium-rich soil treatments surpassed non-selenium-rich soil treatments, respectively. Therefore, increase of selenium content in soil will reduced panicle and improved filled grains number per panicle, setting rate, thousand grains weight and total output.The application of selenium mineral fertilizer impacted effective panicle, filled grains per panicle, setting rate, thousand seeds weight and yield very significantly. The effective panicles was very significantly different from the other treatments and reached the highest level in treatment B1 with 167.5 thousands/667m’; The filled grains per panicle, setting rate,thousand seeds weight and yield reached the lowest level in B1 with 84.19 grains per panicle,66.21%,25.6g and 340.02k g/667m", respectively. In other word, the application of selenium mineral fertilizer reduced the effective panicles, but increased the filled grains number per panicle, setting rate, thousand seeds weight and total output.The differences among soil conditions impacted the selenium content of early rice grain and stem insignificantly and significantly, respectively. Ultimately, we reached the conclusion that the absorption of selenium is slowly relatively. This is the reason for the differences mentioned above.Selenium mineral fertilizer had great significant impacts on the content of selenium in grains and stem of early rice. The content of selenium in grains reached the lowest level with 0kg/667m" of the selenium mineral fertilizer treatment of 0.0827mg/kg. The content of selenium in stem reached the lowest level with 0kg/667m2 of the selenium mineral fertilizer treatment of 0.2181mg/kg. The content of selenium in grains and stem increased very significantly with the increase of the application of selenium mineral fertilizer.The soil conditions impacted the content of selenium of late rice grains and stem very significantly. The content of selenium of late rice grains and stem of selenium-rich soil treatment surpassed those of non-selenium-rich soil treatment very significantly. There must be some differences among rice varieties in selenium absorption, utilization and susceptibility.The application of selenium mineral fertilizer had great effect on the content of selenium of late rice grain and stem. The content of selenium in late rice grain reached the lowest level with Okg/667m2 of the selenium mineral fertilizer treatment of 0.0471mg/kg and the content was below early rice, respectively. The content of selenium in grains of treatments exceeded the control treatment very significantly with the increase of the application of selenium mineral fertilizer. The content of selenium of stem reached the lowest level with Okg/667m2 of the selenium mineral fertilizer treatment of 0.1538mg/kg and the content was below early rice, respectively. The content of selenium of late rice stem improved very significantly with the increase of application of selenium mineral fertilizer. In one word, the application of selenium mineral fertilize increased the content of selenium of grain and stem for a long time but the effect was different for rice varieties. Therefore, rice varieties with high utilization effect for selenium were good choice for extension.Effects of selenium mineral fertilizer application distances on the content of selenium of honeysuckle were very significant. The content reached the highest level in the treatment with distance of 5cm and the treatments with 30cm,10cm,25cm,20 cm and 10 cm were one by one in line. Therefore, the accumulation power of differ-ent root parts were different.Effects of selenium mineral fertilizer application quantity on the content of selenium of honeysuckle were very significant. The content increased with the increase of the application quantity of selenium mineral fertilizer under experime-ntal condition. That is to say, the content of selenium of honeysuckle would be imp-roved by increasing the application quantity of selenium mineral fertilizer.The leave-positions had very significant effects on the content of selenium of oneysuckle and the content increased with the increase of leave position. So, the accumulation of selenium of honeysuckle is relatively slow. The content increased with xperimental time. The application of sele- nium mineral fertilizer improved the content of selenium of cucumber and the content increased with the application quantity of selenium mineral fertilizer. The differences in content of selenium of productions from the same gap in time were insignificant.The application of selenium mineral fertilizer improved the content of selenium of bitter gourd. There is positive correlation between the content of selenium of bitter gourd and the application quantity of selenium mineral fertilizer. The differences in content of selenium of productions from the same gap in time were significant. The content of selenium of produce which were gained in second time were below the produce on the first time significant. We concluded that the selenium in selenium mineral fertilizer was gone.The application of selenium mineral fertilizer improved the content of selenium of eggplant limitedly.The content was below the criterion under experimental conditions. The differences in content of selenium of productions from the same gap in time were insignificant. The content of selenium of produce which were gained in second time were below the produce on the first time significant. That is to say, the selenium accumulation power of eggplant was weak and the selenium in selenium mineral fertilizer was gone.
