How about Jingdan 29 corn seeds, is Jingke 2179 corn varieties suitable for Heilongjiang seeds

Suitable areas: Northeast China, Huanghuaihai, Hubei, Hunan, Guangxi, Yunnan, Sichuan, corn planting areas and similar ecological regions can be planted.

Yield performance: The average yield per mu of the variety was 667 kg in 2000, 715 kg in 2001 in Hunan, 794 kg per mu in 2002, 790 kg per mu in spring sowing, 750 kg per mu in summer sowing, and has the potential to increase yield of 1050 kg per mu.

Characteristics: good fruiting, high yield potential, short stem lodging resistance, developed root system, single plant large spike variety, live stem maturity, resistance to large and small spot disease, silk smut, bacterial wilt, need 10 effective accumulated temperature 2800, spring sowing growth period of about 115 days (spring sowing in Northeast China is 128 days), summer sowing growth period of about 96 days, plant height 250 cm, ear position 100 cm, leaf upstroke, leaf number 22, ear length 23-25 cm, spike row 18-22 rows, red axis grain deep, horse tooth type, Seed yield.

Cultivation points: 1) Spring sowing density of 2800-3000 plants is appropriate, summer sowing density should not exceed 3200 plants (not suitable for dense planting).

2) Medium or above plots should be selected for planting, and chlorine, phosphorus and potassium should be used in a balanced manner when applying chemical fertilizers, and the cultivation method should not be.

so that intercropping or planting is more suitable than empty planting to exert the potential for increasing yield. Sow wheat as early as possible after harvesting and harvest as late as possible.

Hello, the difference between Dongdan 509 and Dongdan 1331 corn planting is that the varieties of corn are different. Dongdan 509 corn is an economical corn with large grains, high grain quality, and strong disease resistance, but low yield, which is suitable for planting in warm climates. Dongdan 1331 corn is a kind of high-yield corn with smaller grains, lower grain quality and weak disease resistance, but higher yield, suitable for planting in warm climates.

Therefore, when choosing corn varieties, we should choose the right varieties according to our actual situation, and get better planting results.

Summary. Kiss: The maturity period of Jingke 2179 corn is about 90 days.

Is Jinke 2179 suitable for northern species.

Dear, I am glad to answer for you: According to the experts' experience in planting in different regions and the traits of Qingyu corn varieties, Jingke 2179 corn varieties can be suitable for planting in Heilongjiang. Experts comprehensively considered the drought tolerance, disease and pest resistance, stress resistance, leaf resistance and grain number of this variety under a variety of climatic conditions, and had a good planting economy of ridge concealment, which can be suitable for planting in Heilongjiang.

How many days of maturity.

Kiss: The maturity period of Jingke 2179 corn is about 90 days.

How many days does it take to plant until the autumn harvest.

Dear, according to the results of my inquiry, on average, Jingke Hanyan 2179 corn takes about 120-135 days from planting to autumn harvest. When the local climate and soil are good, it can be as short as 110 days.

How much is the yield per acre.

Reply to me. The average yield per mu reaches about 800 kg, and the specific yield depends on factors such as soil fertility, temperature and humidity.

The disadvantages of Jingke 836 corn are:1Low yield: The yield of Jingke Ranlugai 836 corn is lower than that of other varieties, which is not good for large-scale planting.

2.Poor disease resistance: Jingke 836 maize has poor disease resistance and is susceptible to pests and diseases, which affects its normal growth and development.

3.Poor drought resistance: Jingke 836 maize has poor drought resistance, and will suffer from severe water deficiency in the dry season, which will affect its normal growth and development.

4.Poor cold resistance: Jingke 836 jade.

The disadvantages of Jingke 968 corn seeds are that the planting area is relatively small, the yield of plum is not high enough, and it is not resistant to rust.

Cultivation technology of Jingke 968 corn seeds: 1Planted on plots above medium fertility.

2.The best sowing period is late April and early May. 3.

Reasonable dense planting: 4-5 leaf stage and time to set seedlings, suitable density of 4000 4500 plants per mu. 4.

Pay attention to the prevention and control of pests and diseases, and harvest when the corn kernel milk disappears or the kernel appears black layer. 5.Proper fertilization:

Apply farmhouse fertilizer or use 40-50 kg of compound fertilizer, 10 kg of potassium phosphate, and 1 kg of zinc fertilizer as base fertilizer. Fertilization is generally carried out 35-37 days after sowing, and about 35 kg of urea is used per mu.

The disadvantages of Jingke are that the planting area is relatively small, the yield is not high enough, and it is not resistant to rust.

Characteristics of Jingke 968 variety: compact plant type, plant height 253cm, ear position 96cm Growth period: about 98 days of summer sowing, about 125 days of spring sowing Accumulated temperature:

2800 Planting density: 3800-4000 acres Variety advantagesSlippery: resistant to bush dense and lodging.

The leaf sheath of the seedlings is lavender, the plant type is semi-compact, the anthers are lavender, and the filaments are red. The panicle is cylindrical, the cob is white, the kernels are yellow, and the semi-dentate is shaped. The disadvantage of Jingke 968 corn seeds is that the planting area is relatively small, the yield is not high enough, and the infiltration wheel is not resistant to rust

Jingke 836 Breeders of this variety: Maize Research Center of Beijing Academy of Agriculture and Forestry Sciences, Beijing Longyun Seed Morning Industry **** Variety performance Dwarf stem plant height 264 Ear position does not exceed 1 meter of panicle open tan Immunity to tung rust Resistance to wilt resistance High temperature resistance The preferred variety for large farmers.

The growth period of spring sowing in Hebei Province was about 132 days, which was 1 day longer than that of Zhengdan 958. The plant is compact, with a plant height of about 280 cm and an ear height of about 118 cm. The fruit panicle is conical, the spike length is about cm, the number of spike rows is 14-16 rows, the cob is red, the grains are yellow, the horsetooth is shaped, the weight of 100 grains is about grams, and the seed yield is produced.

High yield and stable yield, high quality and dense resistance, disease resistance and lodging resistance, small and fine shaft, deep horse teeth, suitable for mechanized harvesting. Yield performance: From 2013 to 2014, we participated in the regional test of spring maize varieties in North East China, and the average yield per mu for two years was kilograms, which was higher than that of the control.

In the production test in 2014, the average yield per mu was kilograms, which was higher than that of the control Zhengdan 958.

Hello dear, I'm glad to answer for you!Jingke 968 has a high output. Jingke 968 - a new variety of high-yield, high-quality multi-resistance and widely suitable corn, Jingke 968 is a new corn variety selected and bred by the Maize Research Center of Beijing Academy of Agriculture and Forestry Sciences, with an annual planting area of more than 20 million mu for many years, with a cumulative total of more than 100 million mu, which is the largest corn variety in China's current spring maize planting area, ranking second in the promotion area of major maize varieties in the country (statistics of the National Agricultural Technology Center in 2019).

Jingke 968 passed the national examination and approval in 2011, and has successively passed the examination and approval of the main corn producing areas such as Huanghuaihai, Northwest, Southwest, and Southeast, as well as the national silage corn approval, becoming the corn variety with the most approved areas and the widest coverage in China, and also the first corn variety approved by the state in China. Nearly 100 points of the national variety test increased the yield by more than 10% on average compared with the control, and set a record of high yield of grains harvested by machinery per mu. The grain quality and silage quality indicators have reached the national standard level.

It has medium resistance to large spot, silk smut, stem rot, gray spot and Curvularia leaf spot, high resistance to corn borer, broad-spectrum resistance to pests such as red spiders, and excellent characteristics such as "high yield, high quality, multi-resistance, wide adaptability, and easy seed production in the cautious calendar" and outstanding advantages such as nitrogen efficiency, barren resistance, drought resistance, salinity-alkali resistance and oligoshine resistance.
