在棉花、玉米苗期的田间管理中,为了提高地温,传统的做法是实行深中耕、深松土。可是车排子试验站和气象站在沙壤土中进行试验却得出了相反的结论。这告诉我们:在农业生产的各个环节中,还有很多未被认识的东西,需要进行探索。当然,这个棉花、玉米苗期松土负效应的试验结果,也只是初步的,各单位仍需结合不同的土壤和其它不同的自然条件进一步研究,使我们的主观认识和客观实际更趋于统一,减少盲目性,以提高我们科学种田的水平。 In cotton, maize seedling field management, in order to improve ground temperature, the traditional practice is to practice deep plowing, deep loosening. However, the car row test stations and weather stations in sandy loam to the test reached the opposite conclusion. This tells us that in all aspects of agricultural production, there are many things that are unknown and need to be explored. Of course, this cotton, maize seedling pine negative effect test results, only preliminary, the units still need to combine different soil and other different natural conditions to further study, so that our subjective understanding and objective reality more unified , Reduce blindness in order to raise the level of our scientific farming.
