On March 29th, Researcher LI Xingpu and LAN Suque from Institute of Cereal and Oil Crops paid field investigation to black wheat planting base in Hengshui. Affected by the flood in autumn, the sowing date of black wheat was delayed and varied greatly from plot to plot. It leads to a big difference in seedling growth.

According to different situation of plots, several field management measurements are pointed below:
1.For seedlings with 5 tillerings, from elongation stage, the management of farmland fertilizer and water should be conducted by 40 cubic meters of water irrigation and 8-10 kg of nitrogenous fertilizer per mu.
2.For seedlings with 4 tillerings, improve temperature and conduct irrigation and fertilization during the late standing stage.
3.For seedlings with 3 tillerings, do not irrigate before the plant has more than 3 leaves. After forming 3 tillerings, few irrigation should be conducted and spray potassium dihydrogen phosphate and brassinolide growth promotes.
