This kind of corn is called popping corn also known as wheat corn. China's popcorn planting area is related to the selection of varieties. 1980 began in the mid-1980s to yellow rose varieties, mainly in Beijing, Hebei, Xinjiang and Shanxi. 1990 began Liaoning became the rising star, Jilin also has a larger area planted. Now in addition to Xinjiang, Ningxia, Shaanxi, Shandong, Henan, Heilongjiang, Jilin and other places have a small amount of planting, mainly concentrated in Liaoning, Hebei and Shanxi area. Varieties are mainly yellow rose and Shen burst 2 and so on. Popping corn has two kinds of conventional species and hybrids, most of which are medium-early maturity varieties. Conventional species yield is low, mu yield 150 to 200 kilograms; kernel expansion burst rate is low, generally 85% to 90%. Hybrid high yield, mu yield 250~350 kilograms, expansion rate up to 90%. Production should be selected with high purity hybrids.

Selection of land isolation Bursting corn kernels are small, weak germination, should choose fertile soil, easy drainage and irrigation, good moisture content of sandy loam plots of planting, sowing depth of 3~4 cm. Because of the different quality with other corn, in order to prevent each other crosstalk affect the expansion rate, must be centralized and isolated planting. Requirements and other varieties of corn distance of 200 meters or more.

Ensure that the density of bursting maize compact, single plant yield is low, reasonable dense planting in order to obtain high yield. Equal spacing planting, row spacing 45 cm, plant spacing 18 cm. Wide and narrow row planting, wide rows of 50 centimeters, narrow rows of 40 centimeters, plant spacing 18 centimeters. Leave 8,000 seedlings per mu. It's better to plant with mulch.

Phased sowing Popping corn male ear development is slow, phased sowing favorable pollination, to prevent baldness. Generally the first spaced rows are sown, and then sown in the empty rows after 5 days. Source:Gold Digger Essay Sample Center

Field Management Early seedling setting and early plowing after emergence; promote strong seedlings early development. The whole development period of 120~150 kg of standard nitrogen fertilizer per mu. Before plowing, apply 10,000 kg of organic fertilizer per mu. When sowing, apply 10 kilograms of diammonium phosphate per mu, 30 kilograms of ammonium nitrate per mu during the trumpet period, and 20 kilograms of ammonium carbonate per mu during the flowering period. Prevent underground pests in the seedling stage, and control aphids in the late stage. Burst corn grout maturity is slow, fully mature before harvest.
