Examination and approval opinion: This variety conforms to the national maize variety examination and approval standard and has passed the examination and approval. Tomorrow, 695 maize is suitable for planting in the middle and late maturing spring maize areas in East China and North China, the spring sowing areas in northern Cangzhou, Beijing and Tianjin. Tomorrow, 695 corn is also suitable for planting in Huanghuaihai summer corn area.
Brief Introduction of Seed Characteristics of Tomorrow 695 Maize
Tomorrow 695 is a new maize variety with high yield and density tolerance selected by Jiangsu Tomorrow Seed Industry through a series of pilot tests. The wholesale price of seeds of this corn variety is relatively reasonable.
And tomorrow, 695 corn will first pass the density group approval of 5000 summer-sown corn in Hebei Province on 20 17, with the approval number: Jishenyu 20 170003.
Short growth period
The growth period of maize 695 from emergence to maturity tomorrow spring is 127 days, and the whole growth period of summer sowing is 103 days, which is more than 1 day earlier than the control, and has no effect on the next sowing.
Good disease resistance
Tomorrow, 695 maize varieties will perform well in two-year national disease resistance identification test and three-year field natural disease identification.
This maize variety is resistant to big leaf spot, small leaf spot, Curvularia leaf spot and head smut, and highly resistant to dwarf mosaic virus, rough dwarf virus, stem rot and other major maize diseases.
High lodging resistance
Tomorrow, the plant type of 695 maize will be compact, with an average plant height of about 255 ~ 278 cm and an ear height of 90 ~ 1 10 cm. The number of leaves of this kind of corn seed is 20, the proportion is moderate and the ear layer is neat and consistent.
Tomorrow's 695 corn stalk has good elasticity, strong toughness, deep roots, three layers of air roots, many strips and strong functions. On the one hand, it enhances the lodging resistance of the plant, especially the lodging resistance.
A wide range of applicable species
Tomorrow, in the two-year experiment and one-year demonstration, in the 34-point experiment in East China, North China, Yellow River and Northwest China every year, the value of yield variation coefficient is the smallest for two consecutive years.
This fully shows that the sensitivity of this maize variety to climatic conditions is extremely low. In addition, corn 695 is suitable for spring planting in Huanghuaihai, Northeast China and Northwest China.
Super-large ear
The ear of this maize variety is large and uniform, with cylindrical ear, ear length of 2 1 ~ 25 cm and ear diameter of 5.3 cm.
In addition, tomorrow's 695 corn will bear good seeds with small bald tips, with 65438 rows per ear +04- 16 rows and 40 grains per row. The seed yield is 90.2%, the 1000-grain weight is 390g, and the average single ear weight is 0.786kg. It is a typical maize variety with large ear and close planting tolerance.
Yield performance
2017-2018,695 maize will participate in the regional test of middle-late maturity spring maize group in East China and North China tomorrow, with an average yield of 806.15kg per mu for two years, which is higher than that of the control Zheng Dan 9581.1.
According to the production test in 20 18, the average yield per mu of 695 maize will be 766.07kg tomorrow, which is119% higher than that of the control Zheng Dan 958.
From July, 2065438 to July, 20 18, he participated in the regional test of Huanghuaihai Summer Corn Group Consortium. Tomorrow, the two-year average yield of 695 maize varieties is 66 1.5 kg, which is 8.6% higher than that of the control Zheng Dan 958.
In the 20 18 production test, the average yield per mu of 695 maize varieties will be 634.6 kg tomorrow, which is 6.9% higher than that of the control Zheng Dan 958.
Good quality-means good quality.
In 695, the bulk density of corn seeds will be 740g/L, with crude protein content 10.29%, crude fat content 3.55%, crude starch content 72. 14% and lysine content 0.29%. Reach the national secondary standard of corn.
Key points of cultivation techniques of tomorrow 695 maize.
① sowing time
In the middle and late-maturing spring corn areas of East China and North China, it is suitable to plant 695 corn seeds from April 25th to May 20th tomorrow, with a planting density of 4,500 plants/mu.
In the Huanghuaihai summer maize area, it is suitable to plant 695 maize seeds from May 5 to June 20 tomorrow, and the planting density is 4500~5000 plants per mu.
When sowing, planting in equal rows or wide and narrow rows can appropriately increase the density of high-water fertile fields and decrease the density of low-water fertile fields.
(2) There should be enough water when sowing.
When sowing at 695 tomorrow, pay attention to soil moisture, ensure that all seedlings are sown at one time, ensure that seedlings are strong, sow at the three-leaf stage, and fix seedlings at the four-leaf stage.
③ Fertilization.
Tomorrow, in terms of fertilization, we will adopt the method of fertilization by stages, apply less seedling fertilizer, then apply ear fertilizer, apply 30~40 kilograms of urea per mu, and pay attention to drought prevention and drainage in the later stage.
④ Pests and diseases
Pay attention to the prevention and control of thrips, cutworms, cotton bollworms, cabbage caterpillars and other pests at the seedling stage of 695 tomorrow. Use phoxim granules to control corn borer at the big trumpet stage, water it in time in case of drought, plough and weed it in time to ensure that there is no shortage of grass throughout the growth period.
