Black corn is not only nutrient-rich, but also has a sugar content of 11.95%, which is 1-3 times higher than that of common corn stalks. It is a good feed for dairy cows and dairy goats. Black corn is a farmer's breed. It has a short plant, narrow foliage, good solidity, and dense planting. Density can be increased by narrowing the plant and row spacing. Planting in stages to extend market supply. Appropriate areas of black corn are suitable for planting in most of the corn planting areas in China. The province has generally promoted planting. There are few black corn processing enterprises, no deep processing capacity, and difficulties in mass production. It is understood that there are also regional differences in our province. In some areas, the market is not very good. Planting around big cities has a relatively broad market prospect. Mainly cultivated varieties 1. Black pearl sweet corn. It is the main cultivar currently being promoted. Its fresh purple grains are arranged neatly, and fresh spiked cooked foods are thin, no slag, sweet and savory, and soft and delicious. The variety has good stress resistance, wide adaptability, high yield, and dry seed yield of 450 kg/mu. Plant height 2.4 meters, spike length 20 cm, double ear rate 95%. Fresh ear harvesting period is 80-85 days and grain maturity period is 105 days. Mu suitable density 3500 strains. The variety is seedling-tolerant, and the base fertilizer must be applied before sowing, and more phosphorus and potassium fertilizers should be applied. Jointing period, flowering period, pay attention to rooting and preventing lodging. 2. Black (purple) waxy maize hybrids. There are Black Dragonfly 1, Black Dragonfly 2 and Black Dragonfly 3. Heilongjing No. 2 has a height of 1.6 meters, a spike length of 12 centimeters, a conical ear, and a small grain. The plant has a compact shape. After ripening and drying, the grain black shrinks. Good taste, sticky fragrant, no slag, is a mid-maturity and early-maturing hybrid. The black corn can be planted in spring and summer. The planting method is basically the same as that of ordinary corn, and the cultivation method is simple. The specific method is to broadcast the first phase in early April, with a spacing of 1 meter and a 0.17-meter spacing, covered with a plastic film. The second sowing was conducted in early May and the distance from the first sowing line was 0.33 meters. The third seeding was carried out in early June. It was not later than June 15 and the spacing was 0.53 meters from the second seeding line. Field management is the same as normal corn. In this way, the duration of listing from the first phase of the ear to the third phase can last up to 3 months. With 2.5-3 kg of seeds per mu, more than 4,000 fresh sticks can be harvested. Appropriate harvesting period and storage resistance Fresh ears of common corn and sweet corn are dehydrated and wrinkled after a half-day or night of storage. The taste deteriorates and can only be sold on the day of harvest. Black corn is much better than ordinary corn and sweet corn in terms of appropriate harvesting time and storability, and the taste is unchanged after 2 days of harvesting.
Chair
With the deepening of the aging of society, the transformation of aging furniture around the aging population has been launched, and the aging furniture has also closely followed the needs of the elderly.
Due to the degradation of bones and joints of the elderly and the gradual weakening of the muscle strength of the waist, higher requirements are put forward for the seat, and the aging chair came into being.
The height of the aging chair should be slightly lower than the knee height of the elderly, and the sitting depth should be the same as the thigh.
In order to prevent the elderly from falling into the cushion, the cushion and backrest of the aging chair should be made of high-density high-rebound sponge, which is soft and hard to sit.
At the same time, the waist position of the backrest is raised to provide a certain support for the waist. With the soft cushion under the backrest, the lumbar spine fits the back leaning curve of the human body, providing strong support for the waist and keeping the body in the most comfortable state.
The aging chair should be made of skin-friendly, breathable, waterproof and easy-to-clean fabric, which can effectively protect the sensitive skin of the elderly.
