Soil testing and fertilization
Since last year, the Municipal Soil and Fertilizer Station has carried out field experiments on the application of “Good Kang Like†and “Compound Microbial Ingredients for Plants†in greenhouse eggplants. They have achieved good application of 71% and 28% respectively on “Blita†eggplant. effect. Applying soil and fertilizer technology to increase crop yield in greenhouses is the goal pursued by agricultural development.
For a long time, due to the serious unevenness of the land in the city, especially since the implementation of the household contract responsibility system, due to the different planting and fertilizing habits of each farmer, the ways, forms and mobility of various nutrients in the soil have been Different, it leads to large differences in soil nutrients between different fields, achieving high yield and stable production of agriculture, and implementing a soil and fertilization plan is imperative. It is understood that in order to implement the "provincial soil testing and formula fertilization action plan", the municipal soil and fertilizer station thoroughly implements the scientific development concept, closely surrounding the city to improve the comprehensive grain production capacity, reduce production costs, increase farmers' income, and closely integrate pollution-free food action. Planning and technology entry projects. From spring to begin to carry out soil testing and fertilizer technology promotion in the massive (cities, districts).
By the end of October last year , the city had completed the collection of soil samples of 4.88 million mu of cultivated land. The project area covered 145 towns and villages, 1058 villages, 7 soil testing laboratories , and more than 100 sets of testing equipment ; class 98 times, the training of professional and technical personnel 4618 people, farmers 108,800 people; the use of television, radio, newspapers and other media to promote soil testing and fertilizer technology, issuing 405,000 fertilization of technical information through a large set of technological rush, farms and other forms of on-site meetings This has greatly improved the level of farmers' scientific and technological farming. A farmer in Yangshuwan Township, Chaoyang County, with the help of experts from the station, introduced high-quality eggplant varieties, from planting to field management. Every time there is a key link in production, experts always come to the greenhouse to propose technical measures. The eggplant is still being harvested, and the expert came to his home to help solve the problem of imbalance in nutrients in the greenhouse. Up to now, the farmer has received a real income of 12,000 yuan. With their help, the farmer and a farmer in Longcheng District implemented straw reactor technology in the shed.
The city's soil and fertilizer station received 38 consultations from farmers and 4 special reports . The CD-ROM of the formula fertilization seminar was broadcasted on TV stations several times. The farmers who requested soil testing and fertilization services were given on-site guidance, which not only facilitated farmers. And played a good role in promoting this work. They also announced nine soil testing and formula fertilizing hotline service telephones in the media such as Yandu Morning News , so that the majority of farmers can consult the soil testing and fertilization technology issues in time.
In the past, farmers' land was often planted regardless of the soil fertility structure, and the fertilization was not changed, which not only wasted fertilizer, but also had low economic benefits and destroyed the soil and ecological environment. In order to improve the soil organic matter content, experts in the soil and fertilizer station have developed a scientific and rational fertilizer formula with strong pertinence and practicality. It is understood that the city's major acquisition of farmland soil samples 61800, acquiring detection data 352 200; fertilization card issuing 519,100; built 72 demonstration area, an area of 21.5 hectares; the implementation of 3414 31 test, proofreading test 33 recipes Screening 101 fertilizer formulations for the main crops in the city . The city has a total of 34 fixed-point production enterprises , screening and identifying 140 designated fertilizer manufacturers, the application area of ​​formula fertilizer is 3.055 million mu, using formula fertilizer 83,000 tons, accumulating 5449 tons of fertilizer , saving cost of RMB 51 million. . The experts at the soil and fertilizer station regretted that due to the special drought last year, the benefits of formula fertilization technology were seriously affected, and the advantages of most formula fertilization plots were not well reflected.
In order to introduce and promote new fertilizers in a timely manner, and to develop green and pollution-free agricultural products production services in the city, the municipal soil and fertilizer station last year introduced and supported local and foreign compound fertilizer production enterprises to promote various humic acid fertilizers on the protected land of the city. The promotion volume reached more than 2,000 tons, the application area reached 50,000 mu times, an increase of more than 4,000 acres compared with the same period of the previous year , and the number of application sheds was nearly 15,000 . The application effect was very good, and the increase in production and income was obvious, which effectively matched the green and pollution-free agricultural products. Development.
Last year, the city won a special fund of 2.5 million yuan for national-level formula fertilization and 1.66 million yuan for provincial soil-measuring formula fertilization . The injection of these special funds strengthened the quality of formula fertilization in the city.
