Reporter Du Yansa Li Haitao Zhang Yuxin Professor Wang Yiwen

Can sweet glutinous corn on the white saline -alkali land, and the output is not low?

In August of this year, Lu Tiannuo 191 officially passed the approval of the Shandong Crop Variety Review Committee. Shandong's first saline -resistant sweet glutinous corn variety was officially born.

What is unknown is that there are two "unexpected joy" behind the birth of this breed.

In addition to the "accidental joy", Lu Tiannuo's research and development team, Liu Xia, deputy director of the Corn Institute of the Shandong Academy of Agricultural Sciences, and his team are "ten years of grinding a sword": screening thousands of materials, running all over the sky in the South China Sea , Also fight with the birds and wisdom ...

Lu Tiannuo 191 is not only a scientific progress, but the added output value it brings is worthy of talking. Lu Tiannuo 191 can not only help farmers increase their income, but also create moon cakes, but also many merchants have smelled Lu Tiannuo's business opportunities.

Unexpected joy!

Shandong's first saline -resistant color sweet glutinous corn variety was born

One day in early August, Liu Xia, deputy director of the Corn Institute of the Shandong Academy of Agricultural Sciences, who was investigating in the field, received a phone call from Binzhou, Shandong. The sweet glutinous corn in the trial field in Xiaopou Town grows up, and Liu Guoli speculates that this year must be a big harvest.

After hearing this news, Liu Xia hurried to Binzhou to check, because these sweet glutinous corn did not grow from ordinary land, but grew from saline -alkali land.

Immediately afterwards, the Shandong Academy of Agricultural Sciences organized experts on August 11 to measure the sweet and glutinous corn selected by saline -alkali land in Wudi County. The planting density was 2957 plants/mu, and the output of fresh ears was 1333.4 kg. This means that Shandong has been successfully planted sweet glutinous corn in saline -alkali land for the first time, which also means that Shandong's first salt -alkali color sweet glutinous corn variety -Lu Tiannuo 191 was officially born.

Located on the Bohai Bay and the border of Jilu, the small Botou Town, the saline of land is high, and the freshwater resources are lacking. There are 63,000 acres of saline -alkali land among 82,000 mu of cultivated land. Wheat and corn acres are generally low.

In the spring of each year, there is a layer of white "gray" floating on the fields of Xiaopou Town, Wudi City, Binzhou. Salt.

There is a local saying called "salt comes with the water, and salt goes with the water", which is the impact of the land on the land on the land on the land of Xiaopou Town. Liu Xia said, "When you come to Xiaopou Town in May, you can still see the white salt on the ground."

Lu Tiannuo 191 corn, which was harvested in August this year, was planted on the land contracted by Sun Hongsheng. Sun Hongsheng told reporters that at the beginning, he had no hope.

Seeing the results of the production measurement, Liu Xia was deeply surprised. "In the first half of this year, because of the epidemic, this test field was in an extensive management state after sowing. In some places, there were no seedlings that could not be replenished in time, but I did not expect to have such a high output. "

Liu Xia estimates, "After refined management, Lu Tiannuo 191 can reach 3,500 plant density/mu, and the output of fresh ears can reach 1500 kg/mu."

Ten years of grinding a sword!

Filter thousands of materials and run all over the South China Sea

Talking about this high -yield, saline -tolerant corn variety -Lu Tiannuo's birth of No. 191, Liu Xia said that this is a "unexpected joy".

Time dates back to 2011. At that time, Liu Xia was studying low -phosphorus corn varieties, but accidentally discovered in the experiment that the variety of corn -resistant corn that was not resistant to low phosphorus showed a unique quality -salt -tolerant.

High -yielding crops in saline -alkali land have always been a difficult problem. This accidental discovery made Liu Xia overjoyed and turned to the second year. Liu Xia and his scientific research team concentrated on developing sweet and glutinous corn varieties with saline -tolerant.

Since 2012, in order to study the varieties of salt -tolerant, anti -falling, and high -yield corn varieties, Liu Xia and her team have paid a full ten years, which can be called "ten years of grinding a sword." From the laboratory to the field, there were countless difficulties during this period. Liu Xia said that the number of materials alone could not be remembered.

In the past ten years, Liu Xia and his team have been trying and error, screening from thousands of materials in the laboratory, and then trial species selected more than 120 varieties in the field. In order to exclude the interference factors to pick a good variety, Liu Xia and his team ran all over the South China Sea, from the province's Dongying, Heze, Linyi, Zibo, to Taiyuan, Ningxia, and Hainan outside the province, leaving their footprints.

In addition to running all over the country all over the country, Liu Xia said that there is also a cry that is crying and laughing, that is, fighting with the birds.

In the test field, the sweet aroma of corn often attracts birds for food. In order to prevent birds, the managers have repeatedly made surprise. At first, the scarecrow scared the bird, but soon the birds were not afraid. Then they mixed with watermelon and even used the meat to cause the birds. Is it watermelon or meat? Birds are ignored. "Sometimes the experimental field can't come out of the seedlings, and the seedlings must prevent birds from coming out." Liu Xia said, "But birds are also a good test standard. The corn that birds eat often are good seedlings." In the end, , Lu Tiannuo, a new species of saline -alkali -alkali -anti -alkali species, started in 2016. This year, it was planted and succeeded in the salt -alkali land containing two thousandths to three -tenth of Xiaopou Town, Wuxi County this year.

On August 19, the reporter saw on the mild saline -alkali land in Xiaopou Town. Lu Tiannuo's 191 plants were straight, and the trees were standing in the field, resistant to the invertedness, and formed a sharp contrast with other experimental varieties.

At the same time, Lu Tiannuo's 191 particles are fuller, and the bud leaves are more compact. The experimental varieties are compared, "some varieties of corn's top buds are not long enough to be easily suffocated."

Song Yuanrui, the Agricultural and Rural Bureau of Binzhou City and Zheng Senior Agricultural Artist, also highly evaluated Lu Tiannuo 191. The ears are neat and the ears are the same. "

In addition to the high output, Lu Tiannuo can be sown from the end of March to mid -July. Liu Xia said, "And the planting cycle is short, it takes 80 days to mature, and ordinary corn takes 110 days."

Not only saline -alkali land, Lu Tiannuo 191 achieved good results on various types of land.

In a park in a parking lot to a cultivated land in Fei County, Linyi City. The land in the park is mostly sandy land and the soil is barren. Liu Xia handed it to the corn species of Lu Tiannuo 191 in the park. In mid -August, Liu Xia came to this sandy park again and found that the corn of Rulu Tiannuo 191 has already been a lot higher than other varieties. Liu Xia said, "In Hainan, Shanxi and other places, Lu Tiannuo's 191 planting effect is also very good."

The value is high!

Can increase income and make moon cakes

The successful test of Lu Tiannuo 191 in mild saline -alkali land is not only scientific progress, but the added output value it brings is worthy of a good talk.

For farmers, Lu Tiannuo 191 has improved the comprehensive utilization benefits of saline -alkali land and also promoted income growth.

Sun Hongsheng had a conclusion of an economic account. "Now, the market price of sweet glutinous corn is 3 yuan/kg, ordinary corn is 2 yuan/kg, deducting the cost of fertilizer and pesticides of 1100 yuan, and the income per mu can reach 2900 yuan. According to this calculation, calculate this calculation. The income of planting Lu Tiannuo 191 is nearly twice the ordinary corn. "

Lin Yixu said that there are already local community group buyers who have contacted Lu Tiannuo 191 corn. "The wholesale price can be given 2 yuan/piece."

Why can local merchants smell Lu Tiannuo 191 corn business opportunities so early? In fact, Lu Tiannuo's 191 corn's name has long been spreading.

Liu Xia said that at this time at this time, after opening the salt -alkali -base corn planting scene in Xiaopou Town, Lu Tiannuo 191 corn in the field was snatched by the local villagers. Lin Yixu said that Lu Tiannuo 191 corn was large, good, and sweet in the saline -alkali land.

In addition, it is worth mentioning that Lu Tiannuo's 191 corn color is still beautiful, and pink purple and rice white indirectly, which also gives Liu Xia inspiration. This year, Liu Xia developed a new type of moon cake. Unlike the traditional moon cake, this moon cake from moon cake skin to moon cake filling, all Lu Tiannuo 191 corn make raw materials.

The biggest feature of this moon cake is the color of moon cake skin. It is the pink purple and rice white of Lu Tiannuo 191 corn, but the color shape is not fixed. "This random sense is also a manifestation of the original ecology." The introduction said that she named this moon cake "Lotus Moonlight" and was applying for an invention patent.

In August of this year, Lu Tiannuo 191 has just passed the approval of the Shandong Crop Variety Review Committee. Liu Xia said that many companies inside and outside the province are contacting the Shandong Academy of Agricultural Sciences to try to obtain the right to use and further develop. On August 19, after hearing the news, Lin Yixu also threw an olive branch to Liu Xia, hoping that the local enterprise could take over the right to use Lu Tiannuo 191 and transform the results on the spot.

Regarding future development, Liu Xia said that at present, Lu Tiannuo 191 has been in good growth in pilot areas in Hainan, Ningxia, Hebei and other places. It is expected to be further promoted in the Yellow River Basin provinces and even southern provinces in the future.
