The results showed that it was effective fertilization way that no basal fertilizer,but seed manure and top-dressing in early stage was used,if seed and fertilizer could not be effectively separated by seeding and fertilization machine when summer maize was directly seeded.

Our study illustrates that interplant green manure may remarkably increase.

Based on the analysis on the relation between interplanted plants and fruit trees, the structure and function of the model of ecological fruit industry in which the fruit tree plant is dominant, animal husbandry, interplant green manure and protection forest are supplementary, are analyzed systematically.

To determine the suitable distance between wheat seeds and fertilizer during mechanical sowing,the seed-fertilizer distance experiments were carried out.
