Description

The Chinese Reed Canarygrass (Phalaris arundinacea L.) is a fine perennial herbage of Gramineae. The wild ripened seeds were collected and sown on the experimental field of the Zhelimu Animal Husbandry College. The former plant of experimental plot is Chinese Crabapple and the cultivating layer is light loam with pH 8.7. The content of nitric N is 33.58 kg/ha, amino N 42.54 kg/ha, organic P 5.6 kg/ha, k 55.97 kg/ha. Clones were set up according to different compositions, that is N, P, K, WP, NPK, CK. the total amount of fertilizer is 23.8 g. The coefficient of absorbing and utilizing of N, P, K were analyzed at tillering stage according to M.K. Kaeomobk’s formula. The contents of crude protein and fat were measured at tillering period. Fresh, dry and seed field were also measured at ripening stage. The result showed that the highest absorbing coefficient (Kn%) of N from soil is composition PK which is 12.36, while CK is 11.09 and composition K is 10.42. The highest absorbing coefficient (Ky%) of N from fertilizer is composition NPK which is 14.78, while CK is 11.09 and all the treatments are higher than control The highest absorbing coefficient (Kn%) of P from soil is composition NP which is 19.52, while CK is 16.30 and all the compositions were higher than CK. The highest absorbing coefficient (Kn%) of K from soil is composition NP which is 19.2, while CK is 16.30 and composition N is 18.12 which is higher than CK. The highest absorbing coefficient (Ky%) of K from fertilizer is composition NPK which is 28.44, CK is 16.30, composition NK is 26.77, while composition K is lower than CK. The highest fresh and dry yield are composition NP with 46.79 t/ha and 33.89 t/ha respectively as compared with CK (30.82 t/ha and 20.54 t/ha). The output of all the compositions is higher than CK. The highest seed field was composition NK which is 0.232 t/ha, while CK is 0.075 t/ha. the composition NK is the highest treatment with the crude protein amount of 25.33$, while CK is 16.8%. The crude fat of CK is 5.4% while the compositions NK and N are both the highest with the percentage of 6.2. The content of crude fat in compositions K, PK, P were lower than CK. The experiment indicates that the yield and quality of Chinese Reed Canarygrass may be increased by employing fertilizer at proper proportions, and the utilizing efficiency of nourishment element from soil and fertilizer was also enhanced. This result provided the theory basis for the production and further study.
