Sunshine News (reporter Zheng Wei) "In the middle of the two fruit trees to dig a 60 cm deep, 80 cm long, 80 cm wide square pit, prepare a punched plastic pipe, in the pit cushion a layer of 10 cm thick straw or organic fertilizer steady, put the plastic pipe in the middle of the pit, fill the surrounding area with a layer of straw and a layer of organic fertilizer, until the pit is filled, and steadfast, flat ..." In the mountain orchard in the pagoda district, the staff is teaching the fruit farmers the operation of pit fertilization water.
In recent years, the apple industry in Baota District is in a critical period of high-quality transformation and development and quality improvement and efficiency improvement. Cultivating advantageous characteristic industries, innovating and developing new technologies, new models and optimizing the team of scientific and technological talents is particularly important, and Baota District has promoted and implemented the integrated technology of pit fertilization and water in mountain orchards for the actual development of dryland and mountain fruit industries in northern Yan'an, with the help of scientific and technological achievement projects.
Pit fertilization water is an efficient, labor-saving, time-saving, convenient new technology, easy to take materials, less investment, fast results, water conservation, widely used in arid water-scarce, less fertilizer orchards, in the production of advantages: one is to absorb soil nutrients and water has a strong ability; the second is the orchard water retention and growth and development effect is good; the third is that trace nutrients are easy to decompose, easy to absorb. Wang Hao, director of the Fruit Industry Bureau of Baota District, said, "In recent years, the pit fertilization water technology has been promoted in the whole district to an area of 30,000 mu, and the radiation has driven the promotion area of the whole city to more than 100,000 mu, which has played a demonstration and typical driving role for the high-quality development of the city's fruit industry."
It is understood that after the implementation of the pit fertilization water project, the first is economic benefits. From the analysis of labor, the saving per mu is up to 200 yuan, the cost reduction per mu is analyzed from the utilization rate of water and fertilizer sources, and the increase in apple production and income is analyzed, and the yield per mu is increased by more than 200 jin, and the income increases by about 500 yuan. The economic benefits are considerable. The second is social benefits. Radiation can drive the steady improvement of the fruit management level in the project area and surrounding townships, which not only improves its own scientific fruit and fruit management capabilities, but also increases economic income. The third is ecological benefits. The implementation of pit fertilization water is the construction of ecological agriculture mode, mainly to green, environmental protection as the theme, the completion of the entire project will not only not produce link pollution, but also can reduce soil erosion, fertilize the soil, improve the use value of land, increase the content of soil organic matter, and promote the sustainable and healthy development of the fruit industry has great practical significance.
