Evolution of Maize varieties in Northeast China

After the great baptism in 2012, just as in Chinese history, there were three Kingdoms after the Han Dynasty, five dynasties and Ten Kingdoms after the Tang Dynasty, and many years of scuffle among warlords after the Qing Dynasty. The northeast has entered a situation of both heroes and heroes. The varieties and evolution of northeast corn in 2013 are as follows:

1. In 2013, throughout the middle and late maturity areas of Northeast China, Xianyu 335 and Zhengdan 958 formed a "confrontation", covering an area between Zhong and Bo, but in the traditional planting areas of these two varieties, a large number of new varieties began to rise for the first time since 2007!

At that time, Xianyu 335 maintained the situation of the largest variety in Northeast China, but in Jilin, the province with the largest planting area, the area was only close to 10 million mu, and the second largest province was not in the Northeast but in the remote North China and Shanxi Province. Xianyu 335 has a statistical planting area of about 20 million mu in the Northeast. Although the lean camel is bigger than the horse, the northeast storm of Xianyu 335 has come to an end!

Nong Hua 101 is the first to rise in the traditional dominant area of Xianyu 335. Because of its long promotion time and excellent marketing work, it became one of the bright spots as the fourth largest variety in Northeast China, especially in Gongzhuling City, Jilin Province. Cao Manager, the local dealer, is also famous in Northeast China.

At the same time, Liangyu series varieties have also sprung up in an all-round way, among which Liangyu 88 has achieved great success in Liaoning and Liangyu 188 in Jilin, but they can not hide the dim light of Liangyu 99. Liangyu 99 has become the absolute main planting in the surrounding areas with pear trees in the second largest corn planting county in Jilin Province as the core. Liangyu has since become another flag of the Northeast, and Ma Xiaozhi of Jilin Lishu Jinhang seed Industry has also become another legend of Northeast dealers!

The varieties with greater synchronous influence were limin 33 and Dika 516, but they were soon submerged by the vast sea of varieties.

In that year, Tiannong 9 completed the layout with an area of nearly one million mu. Although the impact at that time was not great, it laid the foundation for the great development in the past two years.

Jinqing 707 sows the seeds of development in Jilin Nong'an, the largest county of corn in the country. After two years, it will become the main variety centered here!

2. In that year, Zhengdan958 was mainly concentrated in the Sanzhao area of Tongliao in Northeast Inner Mongolia, northern Liaoning, western Jilin and the first accumulated temperate zone of Heilongjiang, and most of the main planting areas were located in the semi-arid areas of the northeast. Generally speaking, it formed a situation of east-west separation with Xianyu 335, with a statistical area of about 18.17 million mu, ranking the second largest variety in Northeast China, which itself is a myth!

But at this time, Zheng Dan 958 finally met its strongest rival, Jingke 968! At that time, Jingke 968 completed the layout with an area of less than 2 million mu. What is the situation to 2015? We can find out through two reports!

The title of Farmer's Daily on October 12, 2015 is "good variety + good marketing ability to accumulate popularity". On October 19th, People's Daily said, "Why is Jingke 968 more popular?" "it is reported that the planting area of Jingke 968 has reached 16 million mu, and that of Tongliao, Inner Mongolia alone, has reached 9 million mu. In this regard, it is estimated that the replacement of varieties from Jingke 968 to Zhengdan 958 will be completed in the 2016 planting season!

3. When it comes to the very precocious corn area in Northeast China, "Demeya area 1" has become a synonym! Since its rise in 2008, with the rapid expansion of the very precocious corn area, Demeia 1 has become a variety of more than 10 million mu in 2013, ranking fourth in the country, third in the northeast, and the first very precocious variety, worthy of the name. At the same time, Demeya 2 ranks second in the extremely precocious area with an area of more than 3 million mu. However, it should be noted that the success of Demeya series varieties is mainly in Heilongjiang. In other regions of extremely precocious corn, such as Hulunbuir League in Inner Mongolia, Lihe 16 and Ji Chengdan 3 were much larger than Demeia in that year. One of the important reasons is that the soil fertility in this region is poorer than Heilongjiang, corn planting density is low, and Demeya's advantages suitable for high-density planting can not be brought into full play here.

Until now, the varieties in the extremely precocious areas of Heilongjiang have remained stable, but Inner Mongolia and other places are in a decisive situation of four varieties: Ruifu No. 1, Demeya No. 1, Tunyu 188 and Longping 702.

Throughout the very precocious area, Rifle 1 shows signs of rising.

4. In the precocious corn area of Northeast China, in 2013, according to the planting area of varieties, the order was Ludan 2, Zhe Dan 37, Ludan 1, Demeiya 3, Longdan 59, Suiyu 7, Suiyu 19 and Suiyu 20. The planting area of the above varieties exceeded one million mu. In the past two years, Suiyu 20 and Demeya 3 have risen the fastest, and Dongnong 254 has also made good achievements.

5. In the mid-precocious corn region of Northeast China, Jidan 27 still ranked third in 2013, while Longju No. 1 and Jidan 519 ranked the top two, but in fact, the planting areas of the three varieties were basically the same. The varieties with more than one million mu are Xinxin 1, Longju 7, Suiyu 10 and Longdan 49. Xinxin No. 1 and Suiyu 23 have made great progress in this area in the past two years.

6. In the middle mature area of northeast China, although Jidan 535 is the control variety, the planting area has fallen over one million mu, and Xianyu 335, Daming 3307 and Xinxin 2 are among the top three. In recent years, the competition in this region is particularly fierce, Huanong 887, first Zhengda 408, Fuer series varieties and so on fully participate in the competition.

7. The late ripening area of Northeast China is mainly in Liaoning. In 2013, Danyu 405, Shen Yu 21 and Danyu ranked among the top three. After that, the area of Danyu 405 expanded year by year. In addition, there is a very large variety, which is skipped here.

The northeast corn region experienced the continuous spread of leaf spot in 2013, 14 and 15 years. This major corn disease began in 2012 at the junction of the northeast semi-humid region and semi-arid zone from Songyuan to Shuangliao. With the serious incidence of Chifeng in 2015, we can see that there are no signs of stopping.

In 2014, the semi-arid region of Northeast China experienced a relatively severe drought.

The main problems encountered in the 2015 corn season are as follows:

(1) Local severe drought

(2) the sowing time in some areas is too late due to spring frost.

(3) small local lodging caused by swan typhoon. It should be highly noted that some very well-known and fast-growing varieties have also produced severe lodging in some areas, which has laid a "landmine" for the next two or three years!

(4) the armyworm occurred more frequently in the central and southern part of Northeast China after 2012.

(5) after the severe occurrence of ear rot and grain rot in Northeast China in 2010, the ear rot and grain rot occurred more seriously in 2014 and 2015.

According to the above situation, at the same time, the progress of grain storage and harvest in Northeast China is relatively fast, and grain sellers can get cash. Although the progress of seed sales in this season is generally later than that in previous years, the overall market situation has actually been determined for what kind of "fire". Many dealers have steadily acquired the profits of this quarter, which is highly consistent with the current market trend!

However, it should be seen that the corn inflection point in Northeast China is emerging. In 2016, in addition to the formal implementation of the revision of the seed Law, what else will be often mentioned by us in the future? wait and see!
