Cultivation and fertilization control sorghum production levels are important measures. This experiment to the output of sorghum and physiological characteristics of cultivation and fertilization measures as the focus, Green elected to the 2nd wine quality sorghum for the materials, design a different culture and different ways of fertilization, the study on the physiological characteristics of sorghum And yield. The results showed that: the handling process between the growth period, effective tiller ears, the number of grain, grain weight, the theoretical yield, the actual output are obvious differences, the process of reproductive age, height, and other indicators of the final output of sorghum and was positively correlated, in 0 -- 24kg/667m2 the N-fertilization, within covered cultivation and fertilizer can significantly improve the sorghum grain yield. In this experiment to T4 (24kg/667m2) deal with the theoretical maximum output and actual output, the best solution-based experiments.
Cultivation pattern and fertilizer levels both are the important measures to adjust and to control the yield of sorghum. By emphasis on planting patterns and applying fertilizer measures exerting effects on physiological properties and yield of sorghum, the experiment takes the quality Qingxuan 2 in brew as raw material to study effects of the controls on physiological properties and yield by designing different cultural patterns and different levels of fertilizer. The result indicates there is remarkable difference among treatments in the course of growth period, stem length, valid tiller ear numbers, number of grain per ear, weight of thousand grains, theoretical yield and actual yield. The indexes such as the course of growth period and stem length are positively correlated to the final yield of sorghum. Within amount of fertilizer, film mulch and fertilizer increase remarkably grain yeild of sorghum. in the experiment, it is the best plan for this experiment because Treatment B2(495.02kg/mu)has the highest theoretical yield and actual yield.
