Abstract:

The impact of foliar application of fertilizer on the characteristics of plant The impact of foliar application of fertilizer on the characteristics of plant growth and bulb yield of Lilium davidii var. unicolor have been studied with the random block design of two factors under the field farmland in semi-arid areas of the central part of Gansu province. The results showed that KH2PO4 can significantly increase the stem diameter and yield of bulb, and urea can significantly promote the growth of leaves.and plant height, stem diameter, leaf area and bulb yield of lily were increased by 16.7%, 17.6%, 11.6% and 12.4% compared with control and reached the highest value when KH2PO4 and urea spraying 3 times, and it is the combined application of two kind of fertilizer. KH2PO4 should be sprayed 3 times, and urea should be 2 or 3 times in the production of field land.
