In order to ensure the harvest quality of corn ears and the effect of straw treatment, reduce the fragmentation rate of ears and grains, and meet the qualified rate of returning straw to the field, the qualified rate of root stubble and the requirements of straw cutting silage, Knapsack Fertilizer Machine must meet 3 operations condition. 1. The harvest of corn with straw silage should be carried out in a timely manner, and the combined harvesting operation should be carried out when the corn ears are just mature and when the straws gradually turn yellow and dry. At this time, harvesting increases the nutrients and moisture of the straw, which is beneficial to silage. 2. The harvesting of corn with straws returned to the field should be carried out at an interval of 3 to 5 days after the fruit kernels are mature, so that the corn kernels are fuller and the corn cobs have low moisture content, which is conducive to the peeling operation. The corn stalks slowly turn yellow, and the reduction in water content is more conducive to crushing the stalks and reducing power loss. 3. According to the size of different plots and the actual situation of the integration of agronomy and agricultural machinery, its planting distance and operation quality requirements, choose suitable machinery and tools, and plan and formulate harvesting routes.
