Black corn is not only nutritious, but its stalks also have a sugar content of 11.95%, which is 1-3 times higher than that of ordinary corn stalks, making it good feed for dairy cows and dairy goats. Black corn is a farm variety with short plants, narrow leaves, good kernel set, and tolerance to dense planting, so density can be increased by reducing plant and row spacing. Staggered sowing is used to extend the market supply period. Suitable regions: black corn is suitable for planting in most corn-growing regions of China and has already been widely promoted and planted in our province. There are few black corn processing enterprises and no deep-processing capacity, so batch production is difficult, and it is mainly sold as fresh young ears at retail. It is understood that there are also regional differences in our province, and market sales are not very good in some areas. Planting around large cities offers relatively broad market prospects. Main varieties
1. Black Pearl sweet corn. It is currently the main promoted variety. Its fresh kernels are purple and neatly arranged, and the fresh ears, when cooked, have thin skin, no residue, both sweetness and aroma, and a soft, delicious taste. This variety has good stress resistance, wide adaptability, and high yield, with dry grain yield reaching 450 kg/mu. Plant height is 2.4 m, ear length is 20 cm, and the double-ear rate is 95%. The fresh ear harvest period is 80-85 days, and the kernel maturity period is 105 days. The suitable density is 3500 plants per mu. This variety tolerates fertilizer at the seedling stage, so sufficient base fertilizer must be applied before sowing, with more phosphorus and potassium fertilizer. During the jointing and flowering stages, pay attention to hilling soil around the roots to prevent lodging.
2. Black (purple) waxy corn hybrids. These include Black Waxy No. 1, Black Waxy No. 2, and Black Waxy No. 3. Black Waxy No. 2 has a plant height of 1.6 m, ear length of 12 cm, conical ears, relatively small kernels, a compact plant shape, and black, shrunken kernels after maturity and drying. It tastes good, is sticky and fragrant with no residue, and is a medium-maturing, early-leaning hybrid. Planting methods: black corn can be sown in spring or summer, and the planting methods are basically the same as those for ordinary corn, with simple cultivation methods. The specific method is to sow the first period in early April, with row spacing of 1 m and plant spacing of 0.17 m, covered with plastic film. Carry out the second sowing in early May, with the row 0.33 m from the first sowing row. Carry out the third sowing in early June, no later than June 15, with the row 0.53 m from the second sowing row. Field management is the same as for ordinary corn. In this way, from the first period of ear harvest to the third period, the market period can last up to 3 months. At a seeding rate of 2.5-3 kg per mu, more than 4000 fresh young ears can be harvested. Suitable harvest period and storability: fresh ears of ordinary corn and sweet corn lose water and wrinkle after being stored for half a day or one night, and the taste deteriorates, so they can only be harvested and sold the same day. Black corn has much better suitable harvest period and storability than ordinary corn and sweet corn, and the taste remains unchanged even when eaten 2 days after harvest.
