Study On The Effects Of Organic Fertilizers On Millet Growing Characters And Yield

The article carried out systematic study on effect of chicken excrements, pig excrements and cow dung on millet growing characters, yield and quality with random block experiment, which aimed to offer theoretic and realistic means for production of safe and high quality millet. The results showed that organic manure can promoted the growth of millet .Comparing with CK, application of organic manure could regulate R/T and increase root dry weight, top dry weight, specific leaf weight, LAI, the content of leaf chlorophyll and net photosynthetic rate. Organic fertilizer can promotes seedling strength and root system in prophase, stem and leaf growth in metaphase and forms heavy strain and big spike in anaphase for prolonged functional period of leaf and high LAI, which set up a base of high yield.The application of organic manure affects accumulation of dry matter and increase the filling speed and per grain weight at the filling stage. In whole growing stage, organic fertilizer can increase the soluble sugar and soluble protein content, especially in anaphase. For the effect of organic fertilizer on millet growing characters, chicken excrements are best, and pig excrements is better than cow dung. For the effect of organic fertilizer level on millet growing characters, the middle-level of chicken and pig excrements is better than high-level and high-level is better than low-level, but the effect increases as amount of cow dung.The organic fertilizer significantly increased the yield of millet. Comparing with CK, the average yield increases 57.89% for chicken excrements, 48.21% for pig excrements and 45.57% for cow dung. Every treatment is significant at 0.05 levels comparing with CK. For the effect of different level of organic fertilizer on yield, the middle-level of chicken excrements and pig excrements are better than other level and yield separately reaches 6685kg and 6216kg per hector. But the effect increases as amount of cow dung and the yield of high-level cow dung reaches 6103 kg per hector. Yield of the middle-level of chicken excrements is significant at 0.05 levels with other treatments, but that of high-level of cow dung is not significant with middle-level of pig excrements.It is similar for effects of three fertilizers on grain weight per ear, ear length, weight of thousand grains as well as rate of grain and straw, but chicken excrements is better than pig excrements, pig excrements is better than cow dung and cow dung is better than contrast. For the effect of chicken excrements and pig excrements, middle-level is better than high-leveland high-level is better than low-level. But for the effect of cow dung, high-level is better than middle-level and middle-level is better than low-level. Organic fertilizer can increase grain weight per ear, ear length as well as rate of grain and straw, but the effect of chicken excrements and pig excrements is not significant on weight of thousand grains except for middle-level of chicken excrements and pig excrements, and the effect of cow dung is significant on weight of thousand grains except for low-level of cow dung.By regressive analysis of millet yielding and formed-factor of yielding, yielding is well linear-related with grain weight per ear, and the equation is y=39190.163+140.695x, r=0.907 R2=0.823 . But millet yielding is not related with weight of thousand grains, plant height and ear length.The treatment of organic fertilizers can increase content of protein, fat and volume weight of millet in some range except for low-level organic fertilizers. For protein content of millet, the effect of chicken excrements is greater than that of pig excrements and the effect of pig excrements is greater than that of cow dung. For fat content of millet, the effect of chicken excrements is greater than that of cow dung and the effect of cow dung is greater than that of. pig excrements as well as contrast. The protein and fat content of low-level (5t/hm2) of chicken excrements is lowest among all treatments of chicken excrements, but that of middle-level (20...
