Maize is a medium-tillage crop, with tall plants, wide row spacing, easy breeding of weeds, and soil consolidation, which must be cultivated in time. According to the study, the role of cultivating in heading stage is even greater. At this time, the cultivator can maintain loose soil, good ventilation, enhance and prolong the vigor of the root system, promote the occurrence and development of secondary root systems, expand the absorption surface, thereby enhancing the resistance to drought and lodging; the cultivator is conducive to soil cultivation and promote the occurrence and support of roots. In order to promote the growth of stems and shoots of the shoots and the differentiation and development of male and female ear, the cultivator improves the permeability of the soil and can coordinate the water, heat and gas in the soil, thereby promoting microbial activity and facilitating the decomposition of organic nutrients. At the same time weeds can be eliminated. Heading cultivator: Perform twice. 1 After the jointing, intensive tillage 9～12cm, cut off part of the lateral roots to root down the roots, and at the same time promote the occurrence and development of support roots; 2 before tasselling (big bell season) combined with top dressing and then a shallow cultivator to breathe, dehumidify, reduce Insects and diseases are breeding. At this time, if any parturition occurs, they should be removed in time to avoid consumption of water nutrients.
