Can you cook corn in summer and solar terms?
There are three planting methods for spring sowing corn.
1, corn clearance. It accounts for more than 50% of the corn area, and is distributed in the plains of the three northeastern provinces and the alpine regions of Inner Mongolia, Shaanxi, Gansu, Shanxi and northern Hebei. Because of the short frost-free period and low temperature, corn is planted in one season, but it plays an important role in crop rotation, usually with spring wheat, sorghum, millet, soybean and other crops. This situation has changed a lot since the 1970s. Due to the rapid increase of corn planting area, it is very difficult to rotate crops, so continuous cropping system of corn has been developed.
2. Intercropping corn and soybeans. It accounts for about 40% of this area and is the main form of corn planting in Northeast China. Corn-soybean intercropping makes full use of the morphological and physiological differences between the two crops, and reasonable collocation improves the utilization rate of light energy, water, soil and air resources. Corn-soybean intercropping can generally increase the yield of grain and beans by about 20%.
3. Spring wheat interplanting with corn. Since 1970s, the planting mode of spring wheat interplanting with corn has gradually formed in northern Shaanxi, northwestern Shanxi and some areas with good water and fertilizer conditions in Liaoning, Gansu and Inner Mongolia. Generally, sowing wheat in wide border, interplanting on ridge or transplanting spring corn can increase yield by 20-30%.
