The source of this variety is M801× FM11,and it takes 133 days from emergence to maturity in the middle-mature spring maize group in Northeast China and North China, with a semi-compact plant type, a plant height of about 269 cm, an ear height of 97 cm and the number of leaves per plant.
1. Introduction of Fumin 985 Corn Seed
1, Fumin 985 maize seeds came from M80 1 × FM11,and the middle-maturing spring maize group in East and North China emerged to maturity 133 days, which was earlier than the control Xianyu 335/kloc-0. The ear height is 97 cm, the number of leaves per plant 19, the ear is tubular, the number of rows per ear 16- 18, the ear length 18.7 cm, the ear diameter 5. 1 cm, the ear axis is red, and the grain is half-dentate.
2. The bulk density of Fumin 985 corn seed is 76 1 g/L, the crude fat content is 4. 16%, the crude protein content is/kloc-0.10%, the lysine content is 0.29%, and the crude starch content is 73.3 1%.
3. This variety conforms to the national corn variety approval standard, and is suitable for planting in the eastern mountainous area of Liaoning Province and parts of northern Liaoning Province in the middle-maturing spring corn area of Northeast China and North China, most parts of Baicheng City, Jilin City and Tonghua City of Jilin Province, parts of Changchun City, Liaoyuan City and Songyuan City, the first accumulated temperature zone of Heilongjiang Province, Chifeng City, Wulanhaote City, Hohhot City, Tongliao City and Baotou City.
Second, matters needing attention before sowing corn seeds
1, Select plot: The planting site should be far away from the industrial and mining areas and highway environment, so as to avoid the influence of urban pollution and industrial production on the growth of corn. The suitable plot for sowing corn should be loose soil, deep soil layer and good fertilizer conservation performance, and it cannot be continuously planted in the same plot during the planting process, otherwise it will easily lead to the spread of pests and diseases.
2. Scientific land preparation: In the process of land preparation, excessive evaporation of soil moisture should be avoided as much as possible, and no large clods should appear in the raked stratum, and the overall effect should be that the upper part is empty and the lower part is solid. In the season of alternating freezing and thawing, the plots must be arranged in time, so that the surface cracks can be leveled in time, which is conducive to soil moisture conservation and moisture improvement.
3. Rational fertilization: In order to ensure sufficient nutrition supply for seeds in the development process, it is necessary to effectively cultivate soil fertility by applying base fertilizer to improve the physical properties of soil, which is beneficial to the root system development of corn seeds.
4. Reasonable close planting: The growing period of corn is short, and the demand for water is large. In the summer in Henan and other central plains, the precipitation is abundant and the temperature is high, so it is more suitable to plant corn twice a year.
