采用随机区组的方法，对玉米免耕栽培生长情况及该栽培方法的化学除草、播种挖穴大小、肥料施用、鼠害防治方法等进行了详细研究。结果表明：玉米免耕栽培具有出苗快、易全苗齐苗、长势较高、产量提高10%---20%、水土流失得到控制等优越性。播种前选用灭绿等41%草甘膦异丙胺盐水剂，出苗后选用苗后乐（烟嘧磺隆与莠去津复配剂）除草，不仅效果好，且成本较低；宜挖小穴播种，即用小锄挖，一般只挖40ml水的体积那么大，只要能将种子放入大约3cm深的土中即可，尽量少动土；中等肥力土壤每公顷施150公斤氮较合理；用炒过的稻谷配制毒鼠饵料灭鼠效果较好。

The field experiments using method of randomized block design were conducted to study on cultivation techniques of no tillage (CTNT) in corn, which were composed by weed control using herbicides, fertilizer application, digging hole size for seeding, and techniques of control and protection for rodents.The results showed that fast and whole emergence, high growth, increase in rice yield by 10%-20% and reduction in outflow of soil and water were observed under CTNT, compared with conventional tillage method. High control efficacy and low cost could be achieved for weed control by applying 41% glyphosate isopropylamine salt AS (Mielv and Tekuai) before seeding and spraying Miaohoule (Nicosulfuron and Atrazine mixture agent)after emergence. Seeding in small holes dogged by small hoe could be more perfect, and the small hole would be 40 mL in volume and 3 cm in depth in order to minimize soil destroy. Additionally, Nitrogen in fertilizer application was 150 kg/hm2 in medium fertility soil and high control efficacy on rodents was achieved using poison baits prepared with fried rice.
