The mantle land, the ridge ridge, the same corn variety, the same cultivation method, but the growth of corn has a world of difference: the live stalk is mature, the root system is developed, there is no lodging, no baldness, the grain is full, the other side leaves Yellow, stalked, knotted corn cobs are thin and small. This is the true portrayal of the corn demonstration field of the Heilongjiang Provincial Soil Testing and Formula Fertilization Project that the reporter saw in the Mandian Township of Acheng District, Harbin.
Good prescription and good for the people
Linshan, Linshu Village, Yangshu Township, Acheng District, told reporters: "I planted 90 acres of land this year, using soil testing formula fertilizer, glutinous rice is very good, Miao Qi, Miao Zhuang, the root system is developed, the autumn is big and the grain is not bald. There are almost no yellow leaves, and the live stalks are ripe, which increases the grain output. Through the demonstration field comparison, the villagers actually see the effect. The formula fertilizer not only saves the cost of planting land, but also allows us to get a good harvest. I think this formula will be next year. Fertilizer will advance throughout the village."
Jin Yuyu from the urban construction village of Acheng District also said: "I planted 78 acres of rice this year, including 33 acres of soil testing and fertilization test. In the depression, I used 45% of the formula fertilizer, 25 kg. The land was not lost at all; when it was split, it used 12 kg of 40% formula fertilizer. I think that the ear fertilizer is very useful. First, the granules are good for farmers, and the second is high organic matter and potassium, so they don't fall."
Yuan Yongcheng of Jixiang Village, Yagou Town, Acheng District, has been planting rice for 6 years. He said that the rice planted in the past few years is a wide variety of rice, and the “old two†urea and diammonium are used every year. It is also often affected by lodging and rice blast. Not 900 pounds, the income is meager. This year, according to the guidance of the teacher of the district agricultural technology promotion center, he used the soil testing formula fertilizer, and the rice grows very well. It is estimated that one mu can hit 1,500 kg.
Habitual fertilization still has some misunderstandings
In the interview, Hu Ruixuan, the station manager of the provincial soil and fat management station, pointed out that this year, the area of ​​corn and rice lodging in our province is relatively large, which has a direct relationship with the unscientific fertilization. The reason for lodging is objectively speaking, there are factors such as wind and pests; but from the perspective of fertilization technology, the nitrogen content of base fertilizer (base fertilizer) is too high, which is also an important cause of lodging. In addition, after fertilization for 25 days after the rice is inserted, it is easy to cause lodging. The peasants worked hard for a year, but due to improper fertilization, on the one hand, the inefficient investment of funds was caused, on the other hand, the disasters and production of crops were caused, and it was really impossible to make a decision.
At present, there are still many misunderstandings in the fertilization of farmers. First, long-term application of chemical fertilizers does not apply farmyard manure, resulting in reduced soil porosity and increased incidence of pests and diseases; second, blind pursuit of high nutrition of fertilizers; third, partial emphasis on nitrogen and phosphate fertilizers, neglect Potassium fertilizer; Fourth, pesticide poisoning is passed on, for example, the phytotoxicity caused by herbicides will make rice seedlings rigid. Therefore, fertilization is not a trivial matter, it is a very scientific technology.
Shi Wenrui, deputy director of the Agricultural Bureau of Acheng District, also said: "Now the farmers are saving trouble, reducing the work link, regardless of the level of fertilizer, blind fertilization, causing soil compaction and limiting the increase in grain yield."
Hu Ruixuan emphasized that scientific fertilization requires agricultural technology experts to pass the soil testing formula, and then through the fertilizer station, with the cooperation of farmers, the soil and fertilizer station will try to expand the coverage and penetration rate of soil testing and fertilization according to local conditions. A farmer can really use scientific fertilization technology to increase production and increase income.
The picture shows the farmers in the corn demonstration field of the soil testing formula fertilization project to check the growth of corn.
