It generally takes about 126 days from emergence to maturity, the plant height is about 255 cm, the ear length is about 26-28 cm, the number of rows per ear is about 18-22 rows, and the ear height is about 100 cm. The ear is long and tubular, with deep axis, developed root system, strong aerial root, strong wind resistance, drought resistance and waterlogging tolerance. Generally, sowing in early May is the best, and plots with medium fertility or above are suitable for planting.
1 .ketai 58 maize seed characteristics
1. This variety generally takes about 126 days from emergence to maturity. The effective accumulated temperature of 10℃ is 2650-2680℃, the plant height is about 255 cm, the number of rows per panicle 18-22 rows, the panicle length is 26-28 cm, the panicle position is about 100 cm, the red axis is cylindrical, the axis is thin and deep, the rice quality is good, and the root system is good.
2. Key points of cultivation: Generally, it is best to plant 50,000-55,000 plants per hectare in plots with a spacing of 9 inches to 1 ft in early May. The adaptation areas are Tiannong 9 and Ketai 1608. Yield performance: the average yield per mu is 2200 kg, and the plots with good fertilizer and water conditions have high management level and high yield potential of more than 35000 kg.
Second, the main value of corn
1. The vitamin content in corn is 5- 10 times that of rice and wheat. Among all staple foods, the nutritional value is the highest, and it also contains high nutrients such as riboflavin. The moisture, active substances, vitamins and other nutrients of fresh corn are much higher than those of old corn, and the nutritional value of special corn is also higher than that of ordinary corn.
2. Corn silk contains crude protein, crude fiber, polysaccharide and crude fat, and the chemical composition of corn silk varies greatly in different periods and varieties, among which the total anthocyanin and total phenol content reach the highest in the milking stage, and the total flavonoids content and antioxidant activity reach the highest in the spinning stage.
3. The content of dietary fiber in corn husk is the highest, but most of it is wasted because of its rough taste and poor water solubility. Straw crushed and returned to the field can be absorbed and utilized by crops, and can slowly decompose and release mineral nutrients in the soil through the action of microorganisms in the soil. Humus and organic matter formed in the decomposition process can provide raw materials for microorganisms and soil organisms in the soil, improve soil fertility and effectively improve soil structure. After treatment, corn stalk can be used as a by-product (feces) produced by feed utilization.
