The stationmaster of agricultural technology is sure that there are four ways for wheat seedlings to become strong.

On April 3, although it was Qingming holiday, Wang Qingli, director of Qinggangji Town Agricultural Technology Station in Cao County, Shandong Province, was still concerned about wheat seedlings. Just after lunch, he came to the field head of Li Ji Village again."This is a thin land with sand alkali, and the seedlings are still weak. We should irrigate the jointing water and apply 30 catties of urea per mu. It's better to spray foliar fertilizer once." Wang Qingli told the director of the village committee.

Since the Spring Festival, Wang Qingli has been running in the fields of Qinggang Town, busy with the matter of "promoting the weak and strengthening" of wheat seedlings. "Affected by last year's autumn drought and winter frost damage, this year's wheat seedlings are not as good as in previous years, mainly for the three types of seedlings more than in previous years." Therefore, seizing the spring tube, the only opportunity for the transformation of wheat seedlings, to promote weak and strong is a top priority." Wang Qingli said.

After more than two months of running around, Wang Qingli summed up his own "turning strong scriptures".

First of all, there is knowledge in fertilizer and water management. Wang Qingli said that early management should be given priority to, highlighting the classified management of seedlings. Three types of wheat fields should be started as early as possible, and it is best to carry out fertilizer and water management at the re-greening stage, topdressing nitrogen and phosphorus fertilizer; two types of wheat fields should be topdressed and watered at the rising stage; and one type of wheat fields should be topdressed and watered at the jointing stage.

"This is especially thanks to the smallholder water project implemented in our town last year, which invested nearly 30 million yuan to develop efficient water-saving irrigation area of 26,000 mu, covering more than half of the land area of our town." Wang Qingli said,"In the past, we had to adjust the Yellow River water for watering in the town. First, when the water came, it was not certain. Second, the watering cost was particularly high, which cost labor and water." Now that the pipeline has reached the ground, farmers can water it whenever they want."

Second, we should mobilize the peasants to suppress hoeing, especially in wheat fields with excessive vegetation, loose soil and some flourishing crops and in dry lands. In early spring to suppress the hoe, can play a role in soil moisture conservation, temperature control and other multiple effects. "The problem now is that the peasants are all going out to work, and if we increase the links of suppression and hoeing, we especially need to mobilize them extensively. We also used various methods such as holding training meetings, inventing white papers, and shouting loudly to try our best to make farmers realize the importance of this link and take the initiative to go into the wheat field to work." Wang Qingli said.

Then there is herbicide and foliar fertilizer spraying. Herbicide is sprayed to prevent grass damage in spring, foliar fertilizer is sprayed to promote early green wheat seedlings, early prosperity. For this link, Wang Qingli particularly affirmed the role of cooperatives, family farms and social service organizations: "It is unrealistic to rely on farmers wearing masks and carrying sprayers." New plant protection machinery such as the 'self-propelled connecting rod sprayer' of large households has played a major role. A machine can be used for dozens of acres or hundreds of acres every day. Those with machines can do it themselves, while those without machines can spend some money to hire them to do it."

Wang Qingli also particularly praised the land trusteeship services launched by some cooperatives: "When farmers go out to work, they will work for farmers. From sowing to harvest, they can provide services. As long as farmers pay service fees, they can wait for wheat harvest, and the yield is not low at all."

Finally, it is to prevent cold injury in late spring. Winter frost damage often occurs in wheat at jointing stage, so pay close attention to weather changes and water in time before cooling down. If freeze injury occurs, we should seize the time to apply quick-acting fertilizer and spray plant growth regulators such as Yuncaiqin lactone and compound sodium nitrophenolate.

"Seize spring, do these four points, promote the weak to become strong." Wang Qingli said with a smile,"If the seedling situation is not good enough, you can seize the wheat flag-picking period to water, to reduce the flowering, increase the number of grains per ear, but also appropriate topdressing."

Does Wang Qingli's four moves work? Qinggangji town party secretary Li Song introduced, At present the town wheat field spring watering has been close to 90%, Topdressing area more than 80%. Compared with spring, the seedling situation has obviously improved, the population is moderate, the individual development is robust, and the proportion of first and second wheat seedlings exceeds 90%. "That is to say, the effect of promoting weakness and strengthening is very good. The transformation of seedling situation is obvious. The proportion of first-and second-class seedlings is basically the same as last year. Do you think it works?" (Author: Lu Bingbing)
