The climate in Gansu Province is arid and belongs to the arid and semi-arid climate. In recent years, a new technology has been proposed for dryland farming, which is based on overcoming the shortage of traditional cultivation techniques. Planting as one of the dry farming. In recent years, with the promotion of full-film double-ridge furrow sowing cultivation techniques, the total film plantation of double-ridge furrow sowing in Gansu province has reached more than 66.67 million hm., and the technology has been demonstrated in some agricultural regions in Qinghai, Ningxia, Inner Mongolia and other provinces. The promotion and application of the full-film double-furrow planting technology has played an important role in the development of dry farming in China. The soil moisture measuring instrument has an extremely wide application in the determination of soil moisture content, and is an important instrument for modern soil research.
At present, the viewpoint that the straw is returned to the field to improve the physical and chemical properties of the soil and affect crop growth has been widely recognized by many scholars at home and abroad. Straw returning can delay the senescence of maize leaves to a certain extent, and promote the transport of corn dry matter to grains. Ma Yongliang et al. studied the effect of corn stalk return on the physical and chemical properties of the soil and found that the soil bulk density decreased, the aggregate structure increased, the soil seepage capacity increased, and the soil conservation performance increased. The return of straw to the field increases the amount of soil microorganisms and enhances the activity, which accelerates the decomposition and transformation of soil organic matter. It is the most effective measure to increase soil organic matter. In the context of the combination of maize full-film double-furrow planting techniques and the return of corn stalks to the field, the literature on soil physiochemical characteristics and maize growth has not been reported. In this experiment, the effects of straw returning on the physical and chemical characteristics of soil and corn growth in the double-ridge furrow layer of maize were studied through different corn straw returning methods, in order to further clarify the development of full-film double-furrow sowing maize technology and ensure that Gansu corn steadily Increase production, promote the corn industry to provide a reference for the sustainable development of circulation, high efficiency, and low consumption.
The soil moisture measuring instrument determines the moisture content of the straw-covered soil, considering the long-term development of the dry corn industry in Gansu, adopting the full-film double-furrow sowing maize cultivation technology combined with the straw returning technology and the two-year application technology This will play a positive role in ensuring steady growth of maize production and improving the sustainable use of soil in dry areas. Comprehensive maize double-ridge furrow sowing technology, production efficiency, straw returning benefit and promotion technical difficulty, adopting the autumn and film-covered whole straw returning field full-membrane double furrow corn corn cultivation technology, with no-tillage for two years Combining with other straw returning technology combined with full-film double-ridge furrow sowing maize cultivation technology, Gansu dry-land corn planting technology can provide reference for the sustainable development of Gansu corn planting industry in the future.
