| Abstract: | The spraying effect of pp333 with different concentration on wheat in different periods is discussed. The results indicated that the application of pp333 can effectively control the length of bottom internode, increase the dry weight per unit of length and the wall thickness of stem, thereby lodging resistance of wheat is increased. Meantime it can guard against the premature senility of later stage, reduce the numbers of sterile spikelet, enhance the numbers of gains per spike and thousand grain weight, increase the yield by 5% 26%. |
